Intel Core i7-4770 advantages



Intel Core i7-4770
  • The Core i7-4770 includes AVX2, F16C and FMA3 instructions, that were introduced in modern microprocessors not too far ago. While these extensions are not broadly used by programs yet, this should improve in future applications.
  • Besides 4 CPU cores, the processor has integrated HD 4600 GPU. This GPU can be used for casual gaming and 3D apps.
  • The CPU is 35% more energy efficient.

i7-3820 vs i7-4770 specifications comparison

The graphs below demonstrate the difference between Intel i7-4770 and Core i7-3820 most important features. These characteristics, as well as an IPC (instructions per cycle) number, determine how well a microprocessor 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.
