Intel Core i7-4770K vs i7-4820K

Mini Review

Intel Core i7-4770K advantages



Intel Core i7-4770K
  • The i7-4770K includes AVX2, F16C and FMA3 instructions, that appeared in modern CPUs not too far ago. Although these extensions are not widely used by applications yet, this should improve in future programs.
  • The i7-4770K comes with integrated HD 4600 Graphics Processing Unit. This GPU is not fast enough to play latest games with all settings on, but it can be used for casual gaming and 3D apps.
  • The i7-4770K processor is 35% more energy efficient than the Core i7-4820K.

i7-4770K vs i7-4820K specifications comparison

The graphs below compare the most important i7-4820K and i7-4770K characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a CPU performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph represents the number of additional threads, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, while 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. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
