10% Faster Than Core i9-12900K In Single-Core & A Massive 35% Gain In Multi-Threaded Tests

Tech News

Intel’s Core i9-13900K Raptor Lake Desktop CPU has once again seen its benchmarks leak out way ahead of launch, offering a huge multi-threaded performance uplift over its 12th Gen predecessor.

Intel Core i9-13900K Raptor Lake 5.5 GHz Desktop CPU 10% Faster In Single & 35% Faster In Multi-Threaded Benchmarks Versus The Core i9-12900K On Average

The Intel Core i9-13900K Raptor Lake CPU tested in the leaked benchmarks is a QS sample that features 24 cores and 32 threads in an 8 P-Core and 16 E-Core configuration. The CPU carries a total of 36 MB of L3 cache and 32 MB of L2 cache for a combined 68 MB of ‘Smart Cache. It also comes with a base (PL1) TDP of 125W & an MTP of around 250W. This chip seems to be running around the same 3.0 GHz base and 5.5 GHz boost clocks as the previous sample though that was leaked yesterday but the same chip also showed boost clocks of up to 5.7 GHz.

In terms of performance, the Intel Core i9-13900K Raptor Lake CPU offered up to a 10% single-core performance increase over the Core i9-12900K Alder Lake CPU on average. In multi-threaded tests, the CPU saw a 35% average performance increase over its predecessors and also reached up to 2.3 times the performance in PugetBench which is very impressive.

At the same clocks, the Raptor Lake chip offers virtually no performance improvement which means that the Raptor Cove cores aren’t delivering any architectural IPC uplifts and the main performance benefits come from the higher clock speeds and increased cache layout.

Once again, these aren’t the final clock speeds so the final performance is expected to be even higher than this leak. At 5.8 GHz, we can expect a single-core improvement of 10% and a multi-core improvement of 40% over the Core i9-12900K. That should also mean a 50% multi-threaded CPU performance increase over the 5950X. AMD on the other hand has said that Zen 4 increases multi-threaded performance by 35% over Zen 3 so it will be an interesting battle for sure.

The Intel 13th Gen Raptor Lake Desktop CPUs including the flagship Core i9-13900K is expected to launch in October on the Z790 platform. The CPUs will be going up against AMD’s Ryzen 7000 CPU lineup which also launches in Fall 2022.
