Intel Core I 7-940 REVIEW

The overclock performance data of bloomfield processors began to appear. Since core i7 processors are the representatives of the new nehalem architecture , the built-in memory controller will help to raise speed in the appropriate applications, the presence of hyper-Threading technology will allow to accelerate multi-threaded applications, but games can not demonstrate a explosive increase in comparison with core 2 Quad processors .

Associate reported some results which compare the processors core i 7-940 (2.93 GHz) and Core 2 Extreme QX9770 (2.93 GHz) in many applications.


Associates used the engineering model core i 7-940 (2.93 GHz), based on B0 stepping. It is completely possible that the series processors will show a higher speed level ; therefore results in question should not be assumed as final.

For simplification in the results analysis we give below the boost value in the selected applications after transfer from yorkfield to bloomfield processor:

• SuperPi - > 19.3%;
• WinRAR 3.71 - > 77.3%;
• Fritz chess benchmark - > 29%;
• Everest memory (Copy) - > 149,7%;
• CineBench - > 25.7%;
• TMPGEnc 4.5 - > 8%;
• 3DMark06 CPU - > 13.9%;
• 3DMark vantage CPU - > 50.5%;
• Half life 2-> 2.3%;
• World In conflict - > 6.7%;
• May's Devil Cry 4-> 5.1%.

In two games, Call of duty 4 and company of heroes, the processor core i 7-940 lose over their predecessor by 8.6% and 7.2% . In the remaining cases the confident superiority of this new architecture is observed. The intensive boost is observed in multithreaded applications memory bandwidth hungry application . Games, as it was assumed, demonstrate only a moderate increase in the performance.

Now here is the detailed info :

CPU :

* Intel Core 2 QX9770 (344x8.5=2.93 GHz ,12 Mb L2 Cache)
* Intel Core 2 QX9770 (400x8=3.2 GHz ,12 Mb L2 Cache)
* Intel Core i7 Extreme 940 (2.93 GHz , 8MB L3 Cache)

* Intel Chipset : 9.0.0.1011

Super Pi and winrar :

Intel Core I 7-940 REVIEW

Super pi is based on the processor cache (and memory for large calculation) while winrar love tide timing and high memory bandwidth , In both case the CPU power also play a large role . Winrar in this case do not miss the occasion to show the large gain from the integrated 3 channel memory controller (this will be confirmed also in memory bandwidth tests)
