Intel Core i7 940 2.93GHz LGA 1366 130W Quad-Core Processor
 
Our today's article will be devoted to aspects not covered in the reviews of the Intel Core i7 architecture and its first representative Intel Core i7 920. Our readers might remember that we have evaluated performance of Core i7 920 in the nominal mode -- with enabled Turbo Boost and Hyper-Threading -- as it works in users' computers.

However, the urge to research is hard to suppress, so we wonder how much performance is added by new technologies used in these CPUs. In this review we shall analyze Core i7 performance in the "minimalistic" mode (without Turbo Boost and Hyper-Threading), with only Hyper-Threading enabled, and with only Turbo Boost enabled. And, of course, we'll compare the results to the nominal mode (both are enabled).

There are some changes in the testbed configuration: in this series of tests we use 6 GB of DDR3 SDRAM memory from Corsair and the ECS X58B-A motherboard. The other parts haven't changed since our previous Core i7 review. Unfortunately, judging by results, our usage of 6 GB of memory instead of 3 GB in the previous series of tests does not allow to compare them directly. So we re-tested the standard configuration with enabled Turbo Boost and Hyper-Threading with the new memory volume and motherboard.
