Intel Xeon Gold 5318S vs Intel Xeon Gold 6334: comparison
Comparison of Intel Xeon Gold 5318S and Intel Xeon Gold 6334: key differences and a full specification table.
Key differences
Intel Xeon Gold 5318S has more cores (24 vs 8) and more threads (48 vs 16).
At the same time, Intel Xeon Gold 6334 has a higher base clock (3.6 GHz vs 2.1 GHz) and a higher maximum clock (3.7 GHz vs 3.4 GHz).
Both processors match on: TDP (165 W), process node (10 nm), maximum memory size (6 TB), memory channels (8), PCIe version (4).
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.
