i7-3960X vs i7-4960X specifications comparison

The charts below compare the most important characteristics of the Core i7-4960X and i7-3960X microprocessors. These features, along with an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph displays 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 for 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.
