Intel Core i7-4770K advantages



Intel Core i7-4770K
  • This microprocessor includes AVX2, F16C and FMA3 instructions. Although these extensions are not extensively used in applications yet, their support should improve in future programs.
  • Like many modern processors, the Core i7-4770K integrates Graphics Processing Unit. This graphics is not powerful enough to run latest games at full resolution, but it can be used for casual gaming and 3D apps.
  • The Intel Core i7-4770K is 44% more energy efficient than the Core i7-3970X.
  • The CPU is priced 66% cheaper.

i7-3970X vs i7-4770K specifications comparison

The graphs below compare the most important Intel Core i7-4770K and i7-3970X characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph displays the number of cores (darker area). Lighter area on the graph corresponds to the number of additional threads, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for extra frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
