Intel Core i9-13900 (non-K) Spotted with 5.60 GHz Max Boost, Geekbenched

An Intel Core i9-13900 "Raptor Lake" (non-K) processor was spotted in the wild by Benchleaks. The non-K parts are expected to have 65 W Processor Base Power and aggressive power-management, compared to the unlocked i9-13900K, although the core configuration is identical: 8 P-cores, and 16 E-cores. Besides tighter power limits out of the box, and a locked multiplier, the i9-13900 also has lower clocks, with its maximum boost frequency for the P-cores set 5.60 GHz, compared to the 5.80 GHz of the i9-13900K. It's still a tad higher than the 5.40 GHz of the i7-13700K.

Tested in Geekbench 5.4.5, the i9-13900 scores 2130 points in the single-threaded test, and 20131 points in the multi-threaded one. Wccftech tabulated these scores in comparison to the current-gen flagship i9-12900K. The i9-13900 ends up 10 percent faster than the i9-12900K in the single-threaded test, and 17 percent faster in the multi-threaded. The single-threaded uplift is thanks to the higher IPC of the "Raptor Cove" P-core, and slightly higher boost clock; while the multi-threaded score is helped not just by the higher IPC, but also the addition of 8 more E-cores.

So here is the highest 12900K score I could find. I wonder if the 13900K will be able to beat the single core score here.

Solid State BrainSingle-core or even 2-core performance should be at a power below the stated long-term/base TDP of 65W.

For MT performance, you should blame hardware reviewers and motherboard manufacturers. The latter especially most often use high or no power-current limits and tons of load voltage (leading to effectively overvolted operating conditions, i.e. voltages exceeding values in the CPU-fused voltage–frequency curve), making default settings far from being true Intel defaults. They are allowed to, since power limits are not a processor specification and any current/voltage is allowed if below the specified limit and temperatures do not exceed TjMax.

Hardware reviewers seem generally clueless about all of this.

If Intel-recommended PL1 (65W) and Tau time for locked processors (recently usually 28s) were actually respected, due to how the algorithm works the CPU would go from 200W to 65W (PL1) within 10 seconds, making PL2 influence on long benchmarks like Cinebench scores limited.

People who want to efficiently use their 65W CPU at 65W no matter what, should tune their motherboard settings accordingly.
the default settings should be default, or either they should allow to select tdp by cooler selection like msi boards.
