Intel Core i7 920 review benchmark and overclocking



The announced in 2006, core architecture , marked the beginning of new high performance desktop and mobile systems. Processors on base Of core combined the superiority on performance over NetBurst architecture , low energy consumption ( low heat emission ) and overclocking potential. The architecture core helped Intel company to avoid the economic problems, connected with relative unpopularity of NetBurst processors . During the last two years Intel consecutively enlarged the possibilities of core architecture , released new revisions, and recently transferred the release of processors to the 45nm technical process. In 2007 Intel stated about the announcement of nehalem architecture ( processors core i7), built on base Of core with a number of cardinal update :

  • The memory controller was transferred from the north bridge (motherboard) directly in the processor itself
  • support 3- X (triple) channel operation mode
  • in contrast to Kentsfield/yorkfield, which consist on two crystals with 2 core each, all 4 core Bloomfield are located on one crystal

At the given moment, the presented core i7 consists on three 4- core processors: 920, 940 and 965 Extreme edition.

Thus, before us the elder and the low-end Core i7 representatives , Core i7 965 Extreme and core i7 920.

The new processor Core i7 is different from Intel core .

core i7 920

The integration of memory controller in the processor core, increased the crystal size , grew in the number of pins , in consequence the CPU surface increased from 38x38 to 42x45 mm.

Core I7 920 Cooler :

Since Core i7 920 is more interesting for most user due to its price (let us recall it will cost $284(wholesale) vs 562$ and 999$ ) we decided to focus mainly on this processor .

Here is the default cooler for this model (Core i7 920).

The new cooler has a larger size and bigger fan in comparison with LGA 775 .

Note the cooling of 775 processor will not be compatible with 1366 socket .

Core I7 920 in details :

But here thermalright company already propose for its most popular cooler a fasting in order to use the old cooler with 1366 socket . The model thermalright ultra-120 eXtreme will be used in out test .

After installing this processor on the motherboard Intel DX58SO on base of x58 chipset , CPU-z will reflect the following information:

Our processor is based on the early stepping C0. Series models will have a newer stepping and correspondingly, possess lower VID (standard voltage), and also, they can be characterized by higher overclocking potential…

Core I7 920 operating temperature :

According to the utility CoreTemp version 0.99, the processor temperature with the regular box Intel cooler , varies in the region 35-40 degrees . Under load (using OCCT utility version 2.0.0 ) the temperature rose to 55-60 degrees .

Core I7 920 overclocking :

The default voltage for this processor is 1.2V (1.16 with full load) , in this case the processor was stable at the frequency 3000 MHz (@ default voltage), but @3100Mhz it immediately crashed under OCCT test. After raising the core voltage to 1.3V it was possible to pass OCCT test at the frequency 3200 MHz . In this case 1.4V gave a stable 3400Mhz. The tendency is clear. We decided to give this processor 1.5V ( :-) , note it is not recommended to use 1.5v ), but @ 3600 MHz the system could not even POST. As it was explained later, the reason for the observed limitation is due to the QPI bus , in other words, The max stable QPI bus is 175 MHz (motherboard limitation ); therefore the processor overclock was limited to 3500MHz.

Core i7 920 overclocked

This result is modest taking in account the 45nm (4 GHz and above is typical ) and the relatively high voltage ( vcore ) simply does not impress.

Now let us say a few words about the memory : The memory frequency as before relay on (multiplier and QPI frequency) ; however, in our case only two multiplier are available : x3 and x4 , correspondingly to the maximum memory frequency 700Mhz , which is very small for DDR3. Therefore, memory timing were lowered to the smallest possible, 6-5-5-15. In this case the memory voltage was 1.74V (Note Intel recommend to not go over 1.65 v for the memory).

Core I7 920 vs Core architecture :

For comparison we used some popular four core processor : Intel Q6600 and Q9450, based on 65nm and 45nm technical processes.

Here is the list of used computer hardware:

Socket 1366:

  • Intel core i7 920 (Engineering sample) Bloomfield C0
  • Intel DX58SO (Engineering sample, Bios 2260 )
Socket 775:
  • Intel core2 quad q6600, Kentsfield G0
  • Intel core2 quad q9450, Yorkfield E0
  • ASUS P5W64-WS evo (Intel x48, Bios 0601)

  • 2x1Gb Kingston KHX14400D3/K2 (DDR 3-1800 CL8, micron D9GTR chips )
  • 1x1Gb OCZ3P16002GK platinum (DDR 3-1600 CL7, micron D9GTR chips )
  • XFX 8600GT XXX edition
  • Intel SSDSA2MH080G1GN (80Gb SSD)
  • Chieftec CFT-750-14CS (750W)
  • No case :-)

Software:

  • Microsoft Windows XP service pack 2
  • Intel INF drivers version 9.1.0.1007
  • nVidia forceWare version 169.21
  • Futuremark 3DMark06 version 1.1.0
  • CineBench r10 version
  • CPUmark99
  • Everest version 4.60.1500
  • Fritz chess benchmark
  • NucleaRUS version 2.0.0
  • ScienceMark version 2.0.0
  • SuperPi version 1.5
  • TechArp x264 HD version 0.59.819M
  • WinRAR version 3.71
  • wPrime version 1.55

Dual vs Triple-channel memory operation modes :

First we decided to answer the question about the real advantages from the three(triple)-channel regime vs two(dual)-channel.

In practice there is no noticeable difference between dual and triple-channel memory operation modes . In the majority of tests the advantage or loss is reduced to a error of measurement, AND the advantage was seen only in some rare case . Later we will check if this advantage is so small due to the sufficiently low processor frequency .

Core i7 920 processor performance at default speed :

Let us examine the processor performance at default speed

Due to HT technology (Hyper-Threading) the advantage Of core i7 920 in multi-threaded tests reaches almost 100%, which greatly impresses.

Core i7 920 processor overclocked performance :

Since our Q6600 refused to overclock over 3.2 GHz we used in this test the Q9450 overclocked to 3.6 GHz and The i920 at 3.5 GHz .

It is clear that Core i7 920 could hold its advantage over Q9450 almost in all tests.

The average performance increase composed 30% which is already good.

Core i7 965 Extreme edition overclocking :

As we said above the overclock of our Core i7 920 was limited by the motherboard QIP bus , We decided to use in this case the extreme version which come with free multiplier. With air cooling, our copy overclocked to 3.8 GHz only , this is relatively modest for $1000 processors. At this frequency it was possible to pass SuperPi 32M, in 9 minutes 20 seconds.

Core i7 965 Extreme edition overclocking

Since our extreme processor proved to be a poor overclocker we decided to start another review with a new copy (to be published later) . But even with the low CPU overclock speed we set a records in the memory information exchange , which composed 21269MB/s and 21.1ns .

The maximum screen shot stable frequency was 4034MHz with 1.55V. Again the overclock of processor is a pure lottery, this is a matter of luck .

Core i7 965 Extreme edition overclocking

A few words a conclusion about Core i7 :

First, we give confirmation about the memory performance, that the difference between two and three- channel operation modes is low even at high CPU frequencies , and the memory latency is better (lower) in the dual-channel regime.

Core i7 920 dual channel

Core i7 920 triple channel

Core i7 does not love excessively high memory capacity . We can reach the frequencies 920-930Mhz with 6-6-5-15, but, absolutely all tests showed a performance loss relative to the same frequency with 7-7-7-16 or 8-7-6-18.

Now let us say a few words about the Intel memory voltage limit equal to : 1.65 v . In practice a constant use of memory with 2.2-2.3V have not influenced at all the overclocking potential/stability (Note we deal here with few days test , the time required to write this review , So some defect may appear for longer operation , but in our case 2.2-2.3 v was pretty safe).

Since the memory controller is build in the processor, the memory overclock depends now also on the processor temperature .

As conclusion, I can say only that core i7 is a new step in the development of desktop processors. Yes, the overclocking potential is low currently , but this may be fixed with time or luck . The use of HT technology and built-in memory controller considerably improved the performance in comparison with previous families processors.

Now this is a question of price since user have to pay not only for the processors. and motherboard Socket 1366 but also for the DDR3 memory ..
