Intel Xeon Gold 6234 vs Intel Xeon Gold 6238L: comparison
Comparison of Intel Xeon Gold 6234 and Intel Xeon Gold 6238L: key differences and a full specification table.
Key differences
Intel Xeon Gold 6234 has a higher base clock (3.3 GHz vs 2.1 GHz), a higher maximum clock (4 GHz vs 3.7 GHz) and a lower TDP (130 W vs 140 W).
At the same time, Intel Xeon Gold 6238L has more cores (22 vs 8), more threads (44 vs 16) and a higher maximum memory size (4.5 TB vs 1 TB).
Both processors match on: process node (14 nm), 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.
