E7-4830 vs X5660 specifications comparison

The graphs below compare the most important characteristics of the Xeon X5660 and Intel E7-4830 processors. These features, along 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, offered 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. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
