Core i7-3770K vs. AMD FX-8150 and Core i7-2600K CPU Review
The Reviewed CPUs
Contents
In the tables below, we compare the main features of the CPUs we included in this review. The Core i7-3770K and the Core i7-2600K support Hyper-Threading technology, which simulates a processing core in each physical core available. Therefore, these processors are recognized as eight-core CPUs by the operating system.
| CPU | Cores | HT | Internal Clock | Turbo Clock | Max Turbo | Core | Technology | TDP | Socket | Price* |
| AMD FX-8150 | 8 | No | 3.6 GHz | 3.9 GHz | 4.2 GHz | Zambezi | 32 nm | 125 W | AM3+ | USD 250 |
| Core i7-2600K | 4 | Yes | 3.4 GHz | 3.8 GHz | 3.8 GHz | Sandy Bridge | 32 nm | 95 W | 1155 | USD 310 |
| Core i7-3770K | 4 | Yes | 3.5 GHz | 3.9 GHz | 3.9 GHz | Ivy Bridge | 22 nm | 77 W | 1155 | USD 313 |
* The prices were researched at Newegg.com on the day we published this review, except for the Core i7-3770K, which is the price provided by Intel.
TDP stands for Thermal Design Power which advises the user of the maximum amount of heat the CPU can dissipate. The CPU cooler must be capable of dissipating at least this amount of heat. It is important to see how the Thermal Dissipation Power (TDP) of the new Core i7-3770K dropped to 77 W, thanks to the new manufacturing process. (Usually, the smaller the manufacturing process is, the less heat is generated.)
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.
| CPU | L1 Cache (I + D) | L2 Cache | L3 Cache | Memory Support | Memory Channels |
| AMD FX-8150 | 64 kB per module + 16 kB per core | 8 MB x 4 | 8 MB total | Up to DDR3-1866 | Two |
| Core i7-2600K | 32 KB + 32 KB per core | 256 KB per core | 8 MB total | Up to DDR3-1333 | Two |
| Core i7-3770K | 32 KB + 32 KB per core | 256 KB per core | 8 MB total | Up to DDR3-1600 | Two |
