Intel Xeon W11955M vs AMD Ryzen 7 6800U: comparison
Comparison of Intel Xeon W11955M and AMD Ryzen 7 6800U: key differences and a full specification table.
Key differences
Intel Xeon W11955M has a higher maximum clock (5 GHz vs 4.7 GHz), a larger L3 cache (24 MB vs 16 MB) and a higher maximum memory size (128 GB vs 64 GB).
At the same time, AMD Ryzen 7 6800U has a finer process node (6 nm vs 10 nm) and a higher maximum integrated graphics clock (2.2 GHz vs 1.45 GHz).
Both processors match on: core count (8), thread count (16), memory channels (2), 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.
