Intel Core i7-3770K advantages



Intel Core i7-3770K
  • The Intel i7-3770K incorporates F16C instructions, that were introduced in modern CPUs not too far ago. These extensions are not widely used in programs yet, but this should improve in future apps.
  • The processor features on-chip HD 4000 GPU. This Graphics Processing Unit can be used for casual gaming and 3D applications.
  • The Intel i7-3770K microprocessor is 49% more energy efficient.
  • The official price of the processor is significantly lower than the price of the Core i7-3970X microprocessor.

i7-3970X vs i7-3770K specifications comparison

The graphs below show the difference between Core i7-3770K and Intel i7-3970X 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 represents 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. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
