E7-4830 vs X5660 specifications comparison
The graphs below show the difference between Xeon X5660 and Xeon E7-4830 most important features. These characteristics, together 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 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. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
