Intel’s Core i9-13900K Raptor Lake CPU leaks are not over and the latest tests ExtremePlayer show us some crazy multi-threading features that simply destroy the Core i9-12900K and Ryzen 9 5950X CPUs.
Intel Core i9-13900K Raptor Lake CPU Delivers A Behemoth Over 12900K and 5950X and Multi-threaded Performance Boost Over 65% 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 is configured at 3.0 GHz base clock, 5.8 GHz (1-2) core single-core boost clock, and 5.5 GHz all-core boost clock (all 8 P-Cores). The CPU has 68MB of combined cache and a 125W PL1 rating that goes up to 250W. The CPU can also consume up to 350W when using “Extreme Performance Mode”. which we detailed here a few hours ago..

The tech store has published CPU-z, Cinebench R23, and AIDA64 cache and memory tests on three different chips, the Intel Core i9-13900K, Core i7-13700K, and Core i5-13600K, using various overclocking configurations and memory DIMMs. According to the results, the Core i9-13900K can overclock up to 6.2 GHz on all P-Cores and up to 5.2 GHz on all E-Cores. Intel Core i7-13700K can also reach 6.2 GHz frequency on their P-Cores, but E-Cores can only go up to 4.7 GHz. Testing was done on the ASUS ROG Maximus Z690 APEX motherboard, while memory overclocking was achieved on the MSI MEG Z690I Unify. The cooling setup includes a liquid-cooled AIO.
As for performance benchmarks, the Intel Core i9-13900K clocked at 6.2GHz P-Core and 4.7GHz E-core scored 1011 points in CPU-z in single core and 16,627.8 in multi-core tests. However, with the 6.1 GHz P-Core and 5.2 GHz E-Core clocks, the multi-threading score increased by 18 percent to reach 195550 points. The single core score saw a small difference and dropped to 991 points, but considering the overall E-core count was higher than the P cores (8 vs 16), multi-threaded performance definitely benefited 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 was over 65% faster than the AMD Ryzen 9 5950X and Intel Core i9-12900K. This shows how much performance can be achieved with chips that will come with the motherboard through proper cooling setup and overclocking.

We also achieved an even better Cinebench R23 result for the Intel Core i9-13900K with 5.8GHz P-Core and 4.7GHz E-Core overclocked. The results show a 57% performance increase over the Core i9-12900K and a 77% improvement over the Ryzen 9 5950X.

But that’s not all, Intel Raptor Lake CPUs also appear to provide great memory support of up to 7400 Mbps on current Z690 motherboards. Core i9-13900K supported DDR5-7400 and Core i7-13700K/Core i5-13600K offers good support for DDR5-7000 memory, while DDR5-6800 is said to be the top spot. There is also Gear 1 support for DDR5 memory up to DDR4-4256-CL17. As for power consumption, the Intel Core i9-13900K consumed about 400W at 1.5V, while the Core i7-13700K consumed about 290W at a voltage over 1.5V to achieve a similar 6.2GHz P-Core overclock.
Judging by the power numbers needed to reach such frequencies, you’ll need the best of the best cooling configuration to keep Raptor Lake in check while overclocking. Intel 13th Gen Raptor Lake Desktop CPUs including the flagship Core i9-13900K expected It will launch on the Z790 platform in October. CPUs will oppose AMD’s Ryzen 7000 CPU series that starts in the Fall of 2022.
