Intel Pentium G6951 vs Intel Pentium G620: comparison

Comparison of Intel Pentium G6951 and Intel Pentium G620: key differences and a full specification table.

Key differences

Intel Pentium G6951 has a higher base clock (2.8 GHz vs 2.6 GHz).

At the same time, Intel Pentium G620 has a lower TDP (65 W vs 73 W) and a higher maximum memory size (32 GB vs 16.38 GB).

Both processors match on: core count (2), thread count (2), L3 cache (3 MB), process node (32 nm), memory channels (2), PCIe version (2).

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.
