Intel Core i7-4770 advantages
- The i7-4770 features AVX2, F16C and FMA3 instructions, that were introduced in the recent past. These extensions are not broadly supported by programs yet, but this should improve in future apps.
- The Core i7-4770 has on-chip HD 4600 GPU. While this graphics is not fast enough to play latest games at full resolution, it can be used for casual gaming and 3D applications.
- The CPU is 35% more energy efficient.
Intel Core i7-4820K advantages
- Base frequency of the processor is higher than the frequency of the Core i7-4770.
- The microprocessor is unlocked. As a result, the processor can be freely overclocked on most motherboards to achieve better performance.
i7-4770 vs i7-4820K specifications comparison
The graphs below compare the most important Intel i7-4820K and i7-4770 characteristics. These features, along with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Number of cores / threads" graph displays the number of cores (darker area). Lighter area on the graph corresponds to the number of extra threads, offered 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.
