CPU Intel Core i9-13900K Raptor Lake 24-Core Overclocked to 6.1GHz, 5.5GHz All-Core Benchmark Beats Threadripper 2990X 32-Core at 30%

More and more Intel Core i9-13900K Raptor Lake CPU benchmarks are leaking and this time around, we’ll see the full power of the chip inside Cinebench.

The latest overclocked performance standards have been published by a member of China’s Baidu Forum, Xiaochun. In the benchmarks, we can once again see the sample Intel Core i9-13900K ES2 CPU that has been making the rounds online. We also saw the Intel Core i7-13700K overclocked to 6GHz yesterday, but not only did we get another record-breaking overclocking but we also see the overall Core i9-13900K overclocking performance potential.

Intel Core i7-13700K 16 Core Raptor Lake CPU Specifications

The Intel Core i7-13700K CPU will be the fastest 13th-generation Core i7 chip on offer in the Raptor Lake CPU lineup. The chip contains 16 cores and 24 threads. This configuration is made possible with 8 P-Cores based on the Raptor Cove architecture and 8 E-Cores based on the Grace Mont infrastructure. The CPU comes with 30MB of L3 cache and 24MB of L2 cache for a total of 54MB of cache. The chip was running at a base speed of 3.4GHz and a boost clock of 5.40GHz. The overall boost is rated at 5.3 GHz for the P-Cores while the E-Cores feature a base clock of 3.4 GHz and a boost clock of 4.3 GHz.

According to the link, the latest benchmarks were made with all cores enabled. The Raptor Cove P-Cores were operating at an overall frequency of 5.5 GHz while the electronic cores were operating at a quad-core frequency of 4.3 GHz. The CPU was running at 1.3V and it is reported that the maximum frequency of the loop was around 4GHz. The 5.5GHz CPU mentioned before is the single-core limit out of the box, so running all cores at 5.5GHz will definitely draw a much higher power draw.

We’ve been told that the Intel Core i9-13900K CPU has a power consumption of around 350W, and while it runs pretty hot, high-end air coolers will have no problem taming the chip at full load. It should also be noted that this overclocking was again done on a high-end cooler (Liquid AIO) and doesn’t include fancy cooling setups like the LN2 or Chillers. In terms of performance numbers, we first have the CPU-z where the chip scores 16605.6 in the multi-threaded tests and 879.7 on the single core. This is lower than the 6 GHz standard because the cores run at a constant clock speed of 5.5 GHz.


The real deal is the Cinebench R23 benchmark which shows a multi-threaded score of 39,365 points. That’s a 43% improvement over the Intel Core i9-12900K processor. We also used some Cinebench R23 performance numbers for AMD’s Ryzen Threadripper chips from the Pugetsystems database and it looks like Intel’s Raptor Lake Core i9-13900K will more or less match the Threadripper 5965WX which also has 24 cores but 48 threads total which is 50% more threads over 13900K .

The CPU outperforms the 32 core / 64 thread Threadripper 2990X by 30% and it is also very close to the Threadripper 3975WX 32 core / 64 chipset which is quite impressive. Note that Ryzen Threadripper chips have a higher base TDP of 280W to work with.

But like I said, the leaker also set a new overclocking record with the Intel Core i9-13900K CPU. While the Raptor Lake Core i7-13700K was pushed to 6.0GHz, the flagship was pushed to 6.1GHz across all eight cores.

The leaker reported that the single-core CPU-z score was above 1000 points. There’s also the core 5.5GHz CPU-z numbers that show a 27% improvement in performance over the stock chip, a 42% improvement over the Core i9-12900K, and a 40% improvement over the Ryzen 9 5950X processor. The single-core score at 6GHz is a bit lower because there are some apps running in the back but it should be around 980-990 like the 13700K 6GHz score we saw yesterday.

Overall, this appears to be some good multi-core performance for the upcoming Raptor Lake chips. We’d still like to wait for some detailed power and temperature numbers, but one thing’s for sure, in the MT missions, Raptor Lake could give AMD’s Raphael a hard time. Intel 13th Gen Raptor Lake Desktop CPUs including the flagship Core i9-13900K are expected to launch in October on the Z790 platform. The CPUs will face AMD’s Ryzen 7000 CPU which will also launch in fall 2022.
