Intel Core i9-13900K Raptor Lake Benchmark leaks online

- Advertisement -

Once again, benchmark results for Intel’s Core i9-13900K Raptor Lake Desktop CPU have been leaked ahead of time, showing a significant multi-threaded performance improvement over its 12th Gen predecessor.

Using an 8 P-Core and 16 E-Core arrangement, the Intel Core i9-13900K Raptor Lake CPU examined in the leaked benchmarks is a QS sample with 24 cores and 32 threads. A total of 68 MB of “Smart Cache” are carried by the CPU in the form of a combined 36 MB of L3 cache and 32 MB of L2 cache. Additionally, it has an MTP of about 250W and a base (PL1) TDP of 125W.

We should anticipate similar clock rates from this sample since it appears to be operating at roughly the same 3.0 GHz base and 5.5 GHz boost clocks as the prior sample that was leaked yesterday. However, that same chip also showed boost clocks of up to 5.7 GHz. It is anticipated that the final chip will achieve single-core boost clocks of up to 5.7–5.8 GHz, however, this won’t be known for sure until the final version hits the market.

The T-Force Delta 32 GB (16 GB x 2) DDR5-6400 memory, a 360mm AIO cooler, and a 1500W Coolermaster Silence II power supply were used to test the CPU on the ASUS ROG Maximus Z690 Extreme motherboard. The GeForce RTX 3060 Ti 8 GB graphics card was utilized for both the 13900K and 12900K.

On average, the Intel Core i9-13900K Raptor Lake CPU outperformed the Core i9-12900K Alder Lake CPU by up to 10% in terms of single-core performance.

 It is particularly impressive that the CPU outperformed its predecessors in multi-threaded tests by an average of 35 percent while also reaching up to 2.3 times the performance in PugetBench.

In terms of performance, the Cinebench R23 benchmark saw a 13.5 percent increase in single-threaded performance and a 40.2 percent increase in multi-threaded performance. Geekbench saw a 10 percent increase in single-threaded performance and a 23 percent gain in multi-threaded performance. CPU-z Bench saw a 9.5 percent increase in single-threaded performance and a 46.3 percent jump in multi-threaded performance. The Core i9-13900K outperformed its predecessor by up to 42 percent in Blender.

In other words, the Raptor Cove cores aren’t giving any architectural IPC uplifts, and the main performance benefits come from the higher clock rates and improved cache layout on the Raptor Lake device, which gives essentially no performance improvement at the same clocks.

The Intel Core i9-13900K Raptor Lake CPU’s package power increased to 420W (PL4) when running the XTU Benchmark, and the 360mm AIO cooler proved insufficient to keep it below 100C. Under premium coolers, the chip appears to be hitting its thermal limit, though this could be a problem with the QS sample. We won’t know for sure, but AMD’s Zen 4 will be significantly more efficient if Intel has overstepped its bounds with Raptor Lake’s power constraints.

Because these aren’t the actual clock speeds, the actual performance is likely to surpass this leak. We can anticipate a single-core improvement of 10% and a multi-core improvement of 40% over the Core i9-12900K at 5.8 GHz. Additionally, it ought to result in a multi-threaded CPU performance improvement of 50% over the 5950X. On the other side, AMD claims that Zen 4 enhances multi-threaded performance by 35% over Zen 3, so the competition will undoubtedly be exciting.

On the Z790 platform, the Intel 13th Gen Raptor Lake desktop CPUs, including the flagship Core i9-13900K, are anticipated to go on sale in October. The Ryzen 7000 CPU family from AMD, which also debuts in the fall of 2022, will compete against these CPUs.
