  • Higher operating frequency of the processor allows it to run most programs faster.

i7-920 vs i7-950 specifications comparison

The charts below show the difference between Intel i7-950 and Intel i7-920 most important characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a microprocessor 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, 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.
