AMD's Zen 6 just got one of its first rough per-clock comparisons against Zen 5, and the early numbers look good. Leaker HXL spotted a Geekbench 7.1.0 listing for the 256-core EPYC 9996, the flagship "Venice" chip AMD launched in July, scoring 2,847 points in single-core on a Dell PowerEdge R9815 server running Linux. User three twenty six on X then locked a Ryzen 7 9700X to 4.1 GHz, matching the EPYC 9996's maximum boost, and got 2,444 points on the same Geekbench version. That works out to roughly 16.5% higher single-core performance for Zen 6 at the same frequency. Apparently, Zen 6 came out ahead in all 15 single-core subtests, with gains ranging from 8.2% in File Compression to 25.7% in HTML5 Browser.
Of course, these scores only give us a general idea about the gains. The EPYC 9996 uses the dense Zen 6c cores, not the full Zen 6 cores expected in desktop Ryzen chips, so it's hard to say how closely these numbers will carry over. The two systems are also wildly different, with a server platform on one side and a 9700X running DDR5-6000 CL34 under CachyOS Linux on the other, and the EPYC listing has since been pulled from the Geekbench database. Still, a double-digit per-clock gain from the dense core variant is quite encouraging. AMD has already confirmed that "Olympic Ridge" desktop CPUs will stay on AM5, though they reportedly won't arrive until 2027, so we can expect more comprehensive performance leaks well before then.
