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) Motherboard : Intel X48

Intel X58 Memory DDR3-1333Mhz 1GB x2

DDR3-1333Mhz 1GB X3 Video card : Geforce Gtx 260 (576/1998/1242) HDD : Seagate SATA 500 GB Operating system and Driver: Windows Vista ultimate SP1

Video Driver : Forceware 177.98

Intel Chipset : 9.0.0.1011 Super Pi and winrar : 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) . Fritz Chess Benchmark is a multi-threaded benchmark which measure the CPU power . The performance noted above is relative to P3 (480 Kilo Nodes Per Second) . Multi-threading help nehalem processor in this benchmark . And here as it was expected the memory bandwidth is huge with nehalem generation processors , thanks to the three channel integrated memory controller . CInebench belong to the rendering tests category : higher core number will result in better result , The 4 virtual cores boost the nehalem processor score while the performance in the single core regime is almost identical to the QX9770 ( 5 % only boost) Some encoding and 8 % performance boost . 3D 2006 overall score do now any significant boost since it is based mainly on the video card . And here the CPU test come with over 13 % increase . The Core i7 940 CPU score just fly . And again thanks to hyper-threading . Overall score was boosted by the CPU score (check above) For gamer as show the picture above , CPU's do no play a big role ( it is better to update the video card for better gaming ) . But let us note the small boost from nehalem CPU in some games , Note Core i7 loose over older Yorkfiled in 2 Games .
