The Reviewed CPUs

In the tables below, we compare the main features of the CPUs we included in this review. The Core i7-2600K supports Hyper-Threading technology, which simulates a processing core in each physical core available. Therefore, this CPU is recognized as an eight-core CPU by the operating system. The Phenom II X6 1100T doesn’t support SSE4 and AVX instructions, and its HyperTransport bus works at 2 GHz (8 GB/s), while FX-8150s work at 2.6 GHz (10.4 GB/s). Another difference between the two is in the memory controller. In the AMD FX-8150 this component works at 2.2 GHz, while in the Phenom II X6 1100T it works at 2 GHz.

The prices were researched at Newegg.com on the day we published this review. The MSRP for the AMD FX-8150 is USD 245; however, today Newegg.com’s price is way above that, probably due to the Law of Supply and Demand. We expect the price of this CPU to drop substantially in the next few weeks.

TDP stands for Thermal Design Power which tells the maximum amount of heat the CPU can dissipate. The CPU cooler must be capable of dissipating at least this amount of heat.

Below we compare the memory cache configuration of the reviewed CPUs. The L2 memory cache of the AMD FX-8150 is shared by each pair of cores. Thus, it has four L2 caches instead of eight.
