EPYC Turin vs Xeon 6 for AI Servers: The Spec Sheet Fight
Under every serious AI server sits a host CPU feeding the accelerators, and in this directory the fight is AMD EPYC Turin against Intel Xeon 6. The dataset carries 27 EPYC 9005 series SKUs and 25 Xeon parts with core counts published, enough to compare the shapes of the two lineups honestly.
AMD's top Turin parts reach 192 cores in this data (the dense Zen 5c SKUs), with the mainstream line stacked thick between 64 and 128 cores and 12 channel DDR5 across the range. Intel's Xeon 6 answers with a split personality: big P core parts for latency sensitive host work and dense E core parts that climb past 100 cores for throughput nodes. For AI serving, where the host mostly moves data and runs tokenization and scheduling, core count per socket and memory channels matter more than peak single thread speed.

Core counts at the top of each line
Neither lineup publishes prices in this dataset; server CPUs move through vendor quotes and system configs, and the blank price column is the truthful one. What the specs do decide is the shape of the node: EPYC for maximum cores and memory bandwidth per socket in GPU dense boxes, Xeon 6 where the workload mixes AI serving with general enterprise compute on the same fleet.
Memory channels deserve one more line, because they are the spec AI hosts feel daily. Both families at the top of this data run 12 channel DDR5, which is what keeps dozens of data loader workers fed while the GPUs compute. Where the families differ is how low the core counts reach: the directory's EPYC list goes down to 16 core parts for light nodes, while the Xeon list concentrates higher up, a hint that AMD is happier selling the small end of the rack as well.
The servers built on both live on the server page, and the rack server build shows how the parts come together at the top end.
