E3-1240 vs E5-2403 specifications comparison

The charts below compare the most important Intel E5-2403 and Intel E3-1240 characteristics. These features, as well as 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 corresponds to the number of additional threads, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent 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.
