i5-8400B vs i5-6500 specifications comparison

The graphs below show the difference between Core i5-6500 and Core i5-8400B most important features. These characteristics, as well as an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Operating frequency" graph 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. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
