Intel Xeon Gold 6246R vs Intel Xeon Gold 6256: comparison
Comparison of Intel Xeon Gold 6246R and Intel Xeon Gold 6256: key differences and a full specification table.
Key differences
Intel Xeon Gold 6246R has more cores (16 vs 12) and more threads (32 vs 24).
At the same time, Intel Xeon Gold 6256 has a higher base clock (3.6 GHz vs 3.4 GHz) and a higher maximum clock (4.5 GHz vs 4.1 GHz).
Both processors match on: TDP (205 W), process node (14 nm), maximum memory size (1 TB), memory channels (6), PCIe version (3).
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.
