Intel Core i9-12900K "Alder Lake" Beats Ryzen Threadripper 2990WX at Cinebench R23 nT
An alleged Intel Core i9-12900K "Alder Lake-S" sample is shown beating the 32-core AMD Ryzen Threadripper 2990WX HEDT processor at AMD's favorite benchmark, Cinebench R23, in its multi-threaded (nT) test. At this point it's not known whether the i9-12900K is overclocked, but the CPU-Z instance in the screenshot reads 5.30 GHz, which could very well be the processor's stock Thermal Velocity Boost frequency. The sample scored upward of 30000 points, putting it above the Threadripper 2990WX reference score in Cinebench.
The 2990WX is based on the "Zen+" microarchitecture, and released in 2018, but is a 32-core/64-thread chip that should have ripped through this rendering workload. The i9-12900K, on the other hand, has eight "Golden Cove" performance cores that have HyperThreading, in addition to 8 "Gracemont" efficiency cores that lack HTT. This benchmark was run on Windows 10, which lacks awareness of the Intel Thread Director, a hardware component that optimizes utilization of the two kinds of CPU cores. Windows 11 is known to feature better awareness of hybrid core architectures. The i9-12900K sample is possibly installed on a Gigabyte Z690 AORUS Ultra motherboard, and has 32 GB of DDR5-5200 memory (two modules, logically four 40-bit channels).
