i7-3930K vs i7-4820K specifications comparison

The graphs below compare the most important Intel Core i7-4820K and i7-3930K features. These characteristics, together 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 represents 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. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
