Intel Core i7-4770 advantages



Intel Core i7-4770
  • The Intel Core i7-4770 processor incorporates AVX2, F16C and FMA3 instructions, that were introduced in the recent past. Even though these extensions are not extensively used by applications yet, their support should improve in future programs.
  • This CPU comes with integrated HD 4600 graphics. This GPU is not fast enough to play latest games at full resolution, but it can be used for casual gaming and 3D apps.
  • The Intel i7-4770 is 35% more energy efficient.

i7-3820 vs i7-4770 specifications comparison

The charts below show the difference between Core i7-4770 and Core i7-3820 most important characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to the number of extra threads, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for additional 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. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
