AMD Ryzen 9 7900X >30% Faster than the Intel Core i9-12900K in Leaked Benchmark Despite Fewer Cores and Lower Power Draw

AMD Ryzen 7000 CPUs allegedly bring about a near-60% increase in performance compared to rival Intel’s Alder Lake-S flagship. These figures come from internal testing at AMD labs using rendering software, V-Ray. The Ryzen 9 7950X manages an impressive 30,168 points, beating the Core i9-12900K (18,646 points) by a fat 57% margin. This drives home the point that not all cores are equal, and sometimes a chip with fewer (more powerful) cores will easily defeat a rival with many more cores. Just look at AMD’s Bulldozer legacy!

An SiSoft benchmark of the Ryzen 9 7900X has been shared by APISAK on Twitter, demonstrating the exception integer compute capabilities of the Zen 4 core architecture. Vermeer and the Zen 3 core powering it were already quite good at processing INT-heavy instructions. With Raphael, AMD has further increased its lead in this department. The 12-core Ryzen 9 7900X is over 30% faster than the 16-core i9-12900K in Dhrystone Long (double-length integer) while also beating it by 27-28% in the Dhrystone Int benchmark.

The floating-point compute capabilities of Zen 4 are less impressive, leaving a fair bit to be desired. In Whetstone single-float, the Ryzen 9 7900X is less than 5% faster than the Core i9-12900K, expanding the lead to just over 10% in double-float. The Zen core’s execution capabilities seem to have improved with longer instructions (perhaps a result of the AVX512 optimization?).

An SiSoft benchmark of the Ryzen 5 7600X has also surfaced (via: momomo_us). Unsurprisingly, the hex-core Ryzen 7000 CPU one-ups the 10-core i5-12600K in integer workloads as well as in double-length floating point instructions. The budget Zen 4 processor is over 40% faster than the 12600K in the Dhrystone double-float benchmark, an interesting observation considering that it falls behind in the single-float test.
