Intel Core i9-13900K Raptor Lake CPU overclocked to 6.2 GHz, more than 65% faster than 12900K and 5950X

Intel’s Core i9-13900K Raptor Lake CPU leaks don’t seem to be over yet, with ExtremePlayer’s latest benchmarks showing us some insane multi-threading capabilities that will only destroy the Core i9-12900K and Ryzen 9 5950X CPUs.

Intel Core i9-13900K Raptor Lake CPU delivers behemoths over 12900K and 5950X and over 65% multi-threaded performance boost when overclocked

The Intel Core i9-13900K is the flagship Raptor Lake CPU with 24 cores and 32 threads in 8 P-Core and 16 E-Core configurations. The CPU was configured with a base clock of 3.0 GHz, a single-core boost clock of 5.8 GHz (1-2) cores, and an all-core boost clock of 5.5 GHz (all 8 P cores). The CPU has 68 MB of combined cache and a 125W PL1 rating of up to 250W. The CPU can also draw up to 350W when using the “Extreme Performance Mode” we detailed here a few hours ago.

The tech outlet has released CPU-z, Cinebench R23 and AIDA64 cache and memory benchmarks using three different Intel Core i9-13900K, Core i7-13700K and Core i5-13600K Intel Core i9-13900K, Core i7-13700K and Core i5-13600K in various overclocked configurations and memory DIMMs chip. Based on the results, the Core i9-13900K can be overclocked up to 6.2 GHz on all of its P-Cores and up to 5.2 GHz on all of its E-Cores. The P-Core of the Intel Core i7-13700K can also hit 6.2 GHz, but the E-Core can only hit 4.7 GHz. Testing was done on an ASUS ROG Maximus Z690 APEX motherboard, while memory overclocking was done on an MSI MEG Z690I Unify. The cooling unit includes a liquid-cooled AIO.

In terms of performance benchmarks, the P-Core i9-13900K has a P-Core clock of 6.2 GHz and an E-core clock of 4.7 GHz, scoring 1011 points and 16627.8 points respectively in the single-core and multi-core tests within CPU-z. But at the 6.1 GHz P-Core and 5.2 GHz E-Core clocks, the multithreading score improved by 18% to 19,550 points. The single-core score was slightly different, down to 991, but given that the total number of E-cores is higher than the P-cores (8 vs. 16), multi-threaded performance definitely benefits more from E-core overclocking.

As for how this performance compares to existing chips, the Intel Core i9-13900K with 6.1/5.2 GHz overclock is over 65% faster than the AMD Ryzen 9 5950X and Intel Core i9-12900K. This shows how much performance can be achieved by overclocking with the right cooling settings and motherboard.

But that’s not all, Intel Raptor Lake CPUs also show excellent memory support up to 7400 Mbps on existing Z690 motherboards. Core i9-13900K supports DDR5-7400, Core i7-13700K/Core i5-13600K provides good support for DDR5-7000 memory, and DDR5-6800 is said to be the best choice. Gear 1 also supports DDR5 memory up to DDR4-4256-CL17. In terms of power consumption, the Intel Core i9-13900K draws about 400W at over 1.5V, while the Core i7-13700K draws about 290W at over 1.5V for a similar 6.2 GHz P-Core overclock .

Judging by the power figures required to reach such frequencies, you will need the best cooling configuration to control Raptor Lake when overclocking. Intel’s 13th Gen Raptor Lake desktop CPUs, including the flagship Core i9-13900K, are expected to launch on the Z790 platform in October. These CPUs will compete with AMD’s Ryzen 7000 CPU lineup, which is also due to launch in fall 2022.
