Platform LGA1156
The processors created under plug LGA1156, actually represent the simplified versions of the first "Nehalemov", the storages which have lost one channel and speed of bus OPI, but grown in low families own videoadapter under one cover with CPU (let while and on the separate chip). Whether it is capable to replace such "scrap" to users топовые "stones" of last generation? We check up! On the test we managed the most powerful binuclear processor of family Core i5 - Core i5-670. Ensured functioning ASRock N55M Pro motherboard on a chipset of Intel N55 with support of the integrated drawing of processors Core i5/i3 and a two-channel set of random access memory DDR3-2200 of manufacture of Kingmax (at the test of not dispersed system frequency of storage made 1333 MHz - above did not allow to expose BIOS). In remaining the configuration of system for Core 15 did not differ from our normal test bench.
To begin with we consider our fresh accessories separately, then we estimate productivity of a new platform and in summary we state an estimation its estimation as a whole.
Processor Core I5-670
Clock rate: 3,46 GHz the Amount of kernels: 2 Technology Hyper-Threading: Tehprotsess:32 of Nanometer the Maximum power consumption is supported: 73 W Cache L1: 2 х 64 KB Cache L2: 2 х 256 KB Cache L3: 4 MB (general) the Integrated graphic kernel: Intel HD Graphics (733 MHz, support DirectX 10) the Price: $300 the Site of the vendor: inlel.ru
On our tests the fastest processor of family Core i5 got. As it is possible to judge by results of tests, this "stone" in overwhelming majority of applications and games overtakes our deserved Core 2 Extreme 0X6700 with its high-grade four kernels without НТ, and frequently overweight of a novelty more than is imposing. It is necessary to mark low enough heating of the processor. With our cooler of Thermaltake MaxOrb with the fixing loosened from numerous reinstallations at the exposed minimum turns of the fan even on frequency of 4,4 GHz the temperature of kernels of the processor under the full loading was nearby quite safe 60°С. And it - at almost full noiselessness of cooling. The built in video kernel, 1 apparently by results of our express test, is absolutely helpless in games even in comparison with far not game discrete videocard Radeon HD5450. But even in the absence of interest to Intel HD Graphics games remains the carrier of pair lacks. Switching-on of the integrated drawing in itself reduces high-speed performance of the computer: productivity in процессорозависимых applications, indifferent to capacity of a graphic subsystem, falls approximately on 5 % in comparison with a configuration equipped with the discrete videocard. Besides, though this problem will excite hardly many, "интеграшка" does not pull resolution above 1920x1200 even in 2D.
Advantages: high-speed performance at level last "квадов" generations Core 2; a low thermal emission at high frequency thanks to the newest technical process of 32 nanometers; good разгонный potential.
Lacks: absolutely powerless in games the built in video kernel; the high price of given specific model CPU.
Verdict: Not exacting to cooling and thus rather fast processor. However, from the point of view of a price and productivity ratio are much more attractive to the buyer of model Core J5-660/661 and Core i5-650. On high-speed performance their difference from the tested copy minimum, and the price more low approximately in one and a half time. The first impression of acquaintance to this tath-board appeared rather pleasant: strict design, solid-state condensers and cabling convenient for the assembly which did not become a noise the small sizes and the dense configuration of elements. Functionality, except for an amount of expansion slots in what it is cut down concerning boards of a standard size of a АТХ (especially pleases presence of four slots of storage instead of two at many miniature матплат). It is possible to consider as the big bonus compatibility with coolers for connector LGA775: at an upgrade from systems of Intel of last generation it is not necessary to be spent for new system of cooling.
To criticize prior to the beginning of operation it is possible only for steam of the moments. Objectively: a modest complete set (only a disk with drivers and a software, a screening stub for a back wall of the case and steam of unpretentious "tails" SATA without latches-fixers) and absence of output DisplayPort (though under it on the back panel it is enough a place, and many competitors have it). Subjectively: complexity of connection of winchesters to connectors SATA (for casings of classical configuration with bay HDD behind a front wall of problems would not arise any, and here in our casing of a non-standard configuration of length of loop SATA there was no for the third, the most remote from connectors, the winchester).
The power supply system amazes imagination with set of phases, but as a whole is quite sufficient for a reliable mass product. Stabilizing of pressure is constructed under the circuit "4+1+1": four phases are given immediately CPU, one is selected for the integrated video kernel, one more for the storage controler (also built in the processor).
Adjustments BIOS are grouped logically and clearly - problems with orientation do not arise. There is a row разгонных adjustments "for teapots": it is possible to set desirable finite frequency CPU and storages from available variants then матплата automatically picks up factor CPU, frequency of the bus, and also raises pressure for support of stability of operation a little. However, if in modes with small acceleration of action of "automatic machine" are faultless, at a choice us of frequency CPU of 4,4 GHz (maximum in an automatic mode of acceleration frequency), pressure appeared are raised матплатой insufficiently for stability support: OS booted, but any ресурсоемкая the task led "to the dark blue screen
Thanks to the letter of our constant reader Maxim it was possible to install a problem because of which leader ATI in any way did not want to work for us at the full capacity "двухголовый" - Radeon HD 5970. The small chest opened simply: excessively artful programmers ATI fastened switching-on CrossFire in drivers on resolution оптимизаций CatalystAI which under our last requirements to tests of graphic cards are disconnected. But now, armed with knowledge, we have possibility to estimate the true productivity of a leader of "a red command".
And as it is impossible coincided with the test of a platform of Intel LGA1166 as gives the chance to compare more adequately high-speed performance old "квада" and new "дуала" with НТ more successfully, Productivity of this videocard explicitly exceeds possibilities of both compared processors so "brake" in tests even in the heaviest graphic modes should become CPU - that to us and it is necessary for detection of the leader in processor tests.
Small manual editing of pressure in adjustments BIOS gave to system of iron stability on frequency of 4,4 GHz (we cited the data of measurements for system in acceleration for these adjustments, but it would be possible to reach and the best result - drew in only time).
It is necessary to mark that at exhibiting attempt it is noticeable more optimistical adjustments, system Boot Failure Guard, called to eliminate a reacceleration error, showed the неработоспособность: to drop excessively uprated setting jumper Clear CMOS on a board helped only. Other defect is board failing to regulate turns of a processor cooler with the 3-contact plug: irrespective of the exposed adjustments, the fan continued to "thresh" on full that forced to use a regulator of turns on the cooler.
Advantages: excellent functionality for small form-factor; convenient cabling; good functions "acceleration for teapots" in BIOS; convenient system of update BIOS from any carrier; compatibility with coolers for LGA775; support of out-of-date interfaces the CATFISH and LPT; / rather reasonable price.
Lacks: inability to regulate turns of a processor cooler with the 3-contact plug of a supply; almost disabled function of protection against reacceleration Boot Failure Guard; problems with acceleration at essential increase of frequency of the bus (the greatest reached stable frequency in operation: 187 MHz against 133 MHz in a nominal); absence of output DisplayPort for integrated in CPU schedules.
Verdict: the Accessible and functional motherboard which quite approaches almost any user who is not fond of extremal acceleration. A dial-up of units of storage of Kingmax Hercules DDR3-2200 storage Type: 240-pin DDR3-2200 Capacity: 2 х 2 Gb Latency: 10-10-10-30 on effective frequency of 2200 MHz Pressure of a supply: 1,5-1,7 In In addition: support of profiles of storage XMP the Price: $320 the Site of the vendor: www.kingmax.com
The first that attracts a sight in this set - package. Not customary even for expensive units of storage футлярчик from the transparent plastic, and a stylish and refined cardboard box with a magnetic latch and the dense filler reliably protecting units from damages.
Advantages: magnificent package; excellent frequency potential; problemless serviceability in mode Command Rate IT.
Lacks: high тайминги on the maximum frequency; / the high price
Verdict: the Magnificent gift for the acquaintance оверклокера by a large holiday. But, perhaps, not the best variant for purchase by criterion of a ratio of cost and efficiency: hardly slow "оверклокерские" 2 х 2 Gb DDR3-2000 can be found dial-ups almost twice more cheaply.
Practical part
For CPU we included following applications in test set: WinRAR 3.90 (the built in test of high-speed performance): determination of productivity CPU in tasks архивирования; SuperPi 1.5 Mod (1 MB, calculation of number of "Pi" with accuracy of 1 million signs after a comma): determination of productivity of one kernel since the multithreading is not supported by this program;
3DMark Vantage (result under two tests CPU): the general estimation of productivity CPU in games; х264 Benchmark HD 3.18 (videoclip code conversion in quality 720р in two passes): an estimation of efficiency CPU in media coding tasks. Also we led comparing of the integrated drawing of Intel HD Graphics with budgetary videocard Radeon HD 5450 in the easiest modes of our graphic tests (even such minitest completely uncovers a sad subject of productivity of the built in drawing of Intel - at increase of adjustments гарантированно will be even worse). Besides, we measured game productivity of both platforms with usage of videocard Radeon HD 5970 under the full program of our tests for videocards (therefore for comparing in the videograph we add Radeon HD 5850 with appropriate explanations on productivity двухчипового a leader in comparison with одночиповым analog). Before looking at schedules, explicitly we describe characteristics of a sheaf "processor/memory" in our configurations: Core 2 Extreme QX6700 in a nominal mode of 2,66 GHz (266 MHz х 10) with storage DDR2-8O0 (тайминги 5-5-5-12 2T); Core 15-670 in a nominal mode of 3,46 GHz (133 MHz х 26) with storage DDR3-1333 (тайминги 8-9-9-24 IT); Core i5-670 in acceleration to 4,4 GHz (176 MHz х 25) with storage DDR3-1760 (тайминги 9-9-9-24 IT).
So, we pass to performance review - at first in CPU-tests, then - in graphic.
WinRAR 3.90
двухьядерника with support of technology Hyper-Threading over aged четырехьядерным a leader of a ruler of Intel it is impossible to name advantage of modern suppressing, but it makes notable enough 15 %. Acceleration to 4,4 GHz (approximately 26 % from a nominal) allows to raise productivity of the leader of the given test for 25 % - quite worthy result. It is necessary to tell that in days of old and our deserved veteran ОХ6700 problemlessly worked on frequency of 3,33 GHz instead of regular 2,66 GHz (25 % of acceleration from a nominal), but taking into account a high thermal emission of this model and collapsing fixing of a cooler to repeat these feats now we did not dare.
SuperPi 1.5 mod
In it однопоточком toast Core i5 has been doomed to an undoubted victory with devastating result: its kernel noticeably exceeds on frequency a kernel old Core 2 Extreme, and the architecture is more perfect. Therefore its overweight in 64 % in a nominal mode looks quite naturally. However "profit" on acceleration at new model is less, than in WinRAR, only 22 % (that, however, too is quite good).
3DMark Vantage CPU
Бенчмарки CPU a popular graphic benchmark package show that occasionally the present kernels it is more useful НТ: advantage Core i5 over "old man" in a nominal falls to a mark of 9,2 %. The gain from acceleration for new model makes 23 %.
х264 Benchmark HD
The unique test where the old leader could struggle as equals practically with середняком new generation: minimum loss (5,3 %) in coding of the first pass has been compensated small (3,3 %) by overweight at handling of the second pass. Since the second pass occupies time approximately in 3,5 times more than the first, it is possible even to tell that actually "veteran" benefited the given test, - let and minimum overweight on points. The gain of high-speed performance from acceleration Core i5 on 26 % made for each pass approximately 23 %. Now it is time to pass to graphic tests (in them we ran Core i5 only on nominal frequency).
ЗОМагк Vantage
Running in each of four official пресетов: Entry, Performance, High and Extreme. Core i5 gives in this test a breath of fresh air двухчиповому to leader ATI: advantage of system on fresher "stone" at the majority of presets of the test makes 18-20 %, but at adjustments High jumps up to 26 %. Notable overweight (and that is characteristic, much more noticeable, than in tests only productivity CPU given бенчмарка: means, the processor will effectively be involved and in graphic tests). If to speak about comparing Radeon HD 5970 with the colleague on the chip - Radeon HD 5850 its advantage is quite expected grows together with adjustments of the test from almost imperceptible quality at minimum setting to almost that 60 % - at maximum. Certainly from two chips Radeon HD 5970, each of which is hardly more powerful 5850 (10 MHz of frequency and superfluous 160 stream processors) it would be possible to expect kernel Radeon HD большего, - but also processors at us at present not the most powerful.
Resident Evil 5 (Benchmark Demo)
The fixed test, рендер DXIO, the maximum adjustments through the menu, resolution 1280х 1024, 1680x1050, 1920x1200 and 2560x1600 on setting by default and with sharing of full screen smoothing 4х and a non-isotropic filtration 16х. If for the previous application passage on Core i5 was a breath of fresh air RE5 from this processor acquires indeed reactive acceleration almost in 60 % at any adjustments. It is obvious that лого "Runs great on Core i7" which game at loading sports, it is quite spread and on Core i5 in which basis the similar architecture lies. One and двухчиповых videocards ATI hinders adequate comparing old CPU: results of both cards practically do not differ, resting against productivity of the processor.
Far Cry 21.03 (built in бенчнарк)
Scene "Ranch Long", рендер DXIO, quality Very High, resolution 1280x1024, 1680x1050, 1920x1200 and 2560x1600 on setting by default and with sharing of full screen smoothing 4х and a non-isotropic filtration 16х. The African jungle brings to fresh architecture of Intel of 10-20 % of a handicap depending on adjustments, but it is difficult to name this superiority solving. For pair videocards the situation is similar with 3DMark Vantage: modest enough overweight двухголового a leader over odnochipo-howl a card up to the highest adjustments at which advantage Radeon HD 5970 becomes devastating.
Crysis Warhead 1.1
Testing by means of utility FRAMEBUFFER Crysis WARHEAD Benchmarking Tool. A demo "frost", рендер DX10, adjustments of quality Gamer, resolution 1280x1024, 1680x1050, 1920х 1200 and 2560x1600 on setting by default and with sharing of full screen smoothing 4х and a non-isotropic filtration 16х. Advantage Core i5 at modest resolutions is expressed much more explicitly, than in the previous game (to 34 % at the most modest setting), but it comes almost to naught at the maximum adjustments - loading on the videocard in heavy modes "Warhead" gives where big, than on the processor. But the gain from the superfluous chip on the videocard is quite notable at any adjustments and in heavy, but enough spread, modes 1680x1050 and 1920x1200 with smoothing and a filtration comes nearer to 50 % and exceeds 60 % accordingly. However the unexpected dip followed in the heaviest mode: leader overweight suddenly fell to rather modest against the described achievements of 27 %.
World in Conflict: Soviet Assault 1.11 (the built in test)
Рендер ПХ10, as much as possible accessible adjustments through the menu (except point "the Image is polluted"), resolution 1280x1024, 1680x1050, 1920х 1200 and 2560x1600 on setting by default and with sharing of full screen smoothing 4х and a non-isotropic filtration 16х. The gain of speed from passage to faster processor made about 20 % at any adjustments - a quite good bonus, considering not the fast rate of game at our setting of quality. The difference in high-speed performance between pair the videocards working with the old processor, becomes explicit only in the heaviest mode - but at once without small on 40 %.
S.T.A.L.K.E.R.: call of Pripyat
(Official бенчмарн)Рендер DX10 and, in the presence of support by the videocard, DX11 (with activated тесселяцией and realistic shades), scene Sun Shafts, quality "High", "the Refined dynamic lighting", mode SSAO "By default", quality SSAO - "High", resolution 1280x1024, 1680х 1050, 1920x1200 and 2560x1600 on setting by default and with sharing of full screen smoothing 4х and a non-isotropic filtration 16х.
This application breaks already settled pattern of absolute and invariable superiority Core J5-670 over Core 2 Extreme 0X6700 the same as and х264 Benchmark HD in purely processor tests. As it is surprising, but last "Stalker" hardly runs on the processor of out-of-date architecture more quickly. Yes, overweight is minimum, - but it nevertheless stablly is available at any adjustments, except the heaviest mode. Obviously, more modern, than our veteran, processors of generation Core 2 (we tell, Core 2 Quad Q9450) bypass Core i5 with more noticeable lift-off. But advantage dvuhchipo-howl videocards here it is uncovered more full and more stablly, than in any other test application: even in the most easy test mode overweight Radeon HD 5970 comes nearer to 50 %, and in more high resolutions approaches to a lath of 60 %.
As a whole we mark that in game configurations двухчиповой the top videocard has nothing to do without the processor of high family (however, it is true also reverse). Is short we comment also on results of comparing of integrated video of Intel HD Graphics with low-end videocard Radeon HD 5450. Rather comparable indexes of high-speed performance are watched only in 3DMark Vantage - but not too considerable lag of the built in decision appreciably consists in application of more powerful processor, whose result at adjustments of quality Entry is rather powerful. In Far Cry 2 the built in decision could not launch game - sheer failure. In Crysis: Warhead and World in Conflict: Soviet Assault the discrete decision shows about double overweight (at drawing reduction, possibly, on Radeon HD 5450 even it turns out to receive conditionally-igrabelnyj фреймрейт). At last, in mode DXI0 frequency of change of frames of an integrated solution conceded in last "Stalker" already in 5 times (however, owners Radeon HD 5450 do not need to be under a delusion: in practice the difference between 1 fps and 5 fps is absolutely not basic).
The abstract for a platform As you can see, productivity of a present average segment from Intel as a whole exceeds позавчерашний "top" (nevertheless for a role of yesterday's leaders approach Core 2 Quad on the updated kernel of Repgup more - with which, seemingly, Core i5 can struggle approximately as equals at lower price). It would seem - well. But it is necessary to mark a row of tendencies causing natural fear in the present policy of Intel. At first, rising разнобой with processor connectors. As all was simple earlier, at the time of Socket 370, Socket 478 (whose existence saddened only presence deadborn Socket 423 with RAMBUS), LGA775... Each of these platforms lived till some years, being a basis for all modern to it of Intel processors. What now? The analog разнобою with LGA1366 and LGA1156 can be found only in the history AMD with parallel existence Socket 754 and Socket 939 (but as a result and AMD came to the sensible decision on unification). Moreover: Platform LGA1156 is shattered because of presence of processors with the built in video kernel and without that, and for involvement of this video kernel is necessary матплата on other chipset. Unless the traditional system where the graphic chip is built in the motherboard, and buyer of the processor looks no more logical forces to pay extra nobody for functionality unnecessary it (to us it explain increase of high-speed performance of a sheaf "processor-storage-video" - whether but so it is necessary for low-end without game claims?) . And after all that second chip under a cover costs money, as well as promised on the future both main vendors of processors additional segments of silicon under a video kernel on one crystal with CPU! Where unification and uniformity for the user? In the second queue we mark permanent increase of cost of motherboards, including and intended for usage of the integrated drawing. If to take the same production of ASRock, that a cheap board of present generation on Intel N55 chipset, ASRock H55M-LE, $80 (besides, by the way, that we pay for the integrated video chip separately, buying the processor) costs dearer. Whereas the decision on a chipset of last generation of Intel G41 in the name of ASRock G4IM-S it is possible to take cheaper than $50, and such difference in the price cannot be justified only cheap more quality elements. As a result our judgement on platform LGA1156 as a whole can be expressed as follows:
Advantages: the reasonable price of processors; / worthy productivity; good possibilities of the extension.
Lacks: absence of cheap motherboards; разнобой with the chipsets which are supporting and not supporting to the drawing built in the processor (for example, chipsets of Intel R55 and Н55 - on them earn any processors LGA1156 but to use the integrated drawing it will be possible only on the second chipset); the mandatory overpayment for any buyer CPU with the integrated drawing even if to use it it does not intend.
Verdict: Despite our grumbling hardly above, LGA1156 as a whole is enough balanced on the price, high-speed performance and power consumption by a platform, except for impossibility of creation on its basis of superbudgetary configurations for that money in which products of last generations (are not present absolutely cheap processors, матплат a category "$50") allowed to be laid down. Besides, self-collectors need not to be tangled in indexes of chipsets not to take a product with unnecessary functionality which or does not allow to use the integrated drawing, or on the contrary - takes video outputs a place on the back panel which would be useful for superfluous USB-ports or others raze. Generally is better for us, users, there would be a decision of Intel on release of models CPU Core i5/i3 without unnecessary for many makeweight in the form of the integrated drawing: judging by the area of a crystal of the video chip to overpay for it it is necessary fairly.
