Intel Core i5-8265U vs Intel Core i5-8500B: comparison

Comparison of Intel Core i5-8265U and Intel Core i5-8500B: key differences and a full specification table.

Key differences

Intel Core i5-8265U has more threads (8 vs 6) and a lower TDP (15 W vs 65 W).

At the same time, Intel Core i5-8500B has more cores (6 vs 4), a higher base clock (3 GHz vs 1.6 GHz), a higher maximum clock (4.1 GHz vs 3.9 GHz) and a larger L3 cache (9 MB vs 6 MB).

Both processors match on: process node (14 nm), maximum memory size (64 GB), memory channels (2), PCIe version (3), maximum integrated graphics clock (1.1 GHz).

These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
