More and more Intel Core i9-13900K Raptor Lake flagship CPU benchmarks are leaking and this time, we can see the full power of the chip inside Cinebench.
Intel Raptor Lake Core i9-13900K 24 core CPU overclocked to 5.5 GHz all core, matches 24 core Threadripper 5965WX
The latest overclocking performance benchmarks were posted by Chinese Baidu forum member Xiaochun. In the benchmarks, we can once again see the Intel Core i9-13900K ES2 CPU sampler that has been making the rounds on the internet. We also saw the Intel Core i7-13700K overclocked to 6GHz yesterday, but not only did we get another overclock record, but we also got to see the overclocking performance potential of the all-core Core i9-13900K.
Intel Core i7-13700K 16 Core Raptor Lake CPU Specifications
The Intel Core i7-13700K CPU will be the fastest 13th Gen Core i7 chip offered within the Raptor Lake CPU lineup. The chip has a total of 16 cores and 24 threads. This configuration is possible with 8 P-Core based on Raptor Cove architecture and 8 E-Core based on Grace Mont core architecture. The CPU comes with 30 MB of L3 cache and 24 MB of L2 cache for a combined total of 54 MB of cache. The chip was running at a base clock of 3.4 GHz and a boost clock of 5.40 GHz. The all core boost is rated at 5.3 GHz for the P cores, while the e-cores feature a 3.4 GHz base clock and a 4.3 GHz boost clock.

According to the leaker, the latest benchmarks were done with all cores enabled. The Raptor Cove P cores ran at an all core frequency of 5.5 GHz, while the E cores ran at an all core frequency of 4.3 GHz. The CPU ran on a voltage of 1.3 V and it is claimed that the maximum ringing frequency was around 4 GHz. The 5.5 GHz CPU mentioned above is the single core limit out of the box, so having all cores running at 5.5 GHz definitely will result in much higher power consumption.
We’ve been told that the Intel Core i9-13900K CPU has a power draw of around 350W and while it runs very hot, high-end air coolers will have no trouble taming the chip under full load. It should also be mentioned that this particular overclock was once again done on a high-end cooler (Liquid AIO) and does not involve fancy cooling setups like LN2 or Chillers. So when it comes to performance numbers, we first have CPU-z where the chip scores 16,605.6 points in multi-threaded tests and 879.7 points in single core. This is lower than the 6 GHz benchmark as the cores run at a fixed 5.5 GHz clock speed.
The real deal is the Cinebench R23 benchmark which shows a multi-threaded score of 39,365 points. This is a 43% improvement over the Intel Core i9-12900K. We also used some Cinebench R23 performance figures of AMD’s Ryzen Threadripper chips from the Pugetsystems database and it looks like Intel’s Raptor Lake Core i9-13900K would more or less match the Threadripper 5965WX, which also has 24 cores. but a total of 48 threads, which is 50% more threads than 13900K.
The CPU outperforms the 32 core/64 thread Threadripper 2990X by 30% and also comes very close to the 32 core/64 thread Threadripper 3975WX chip, which is very impressive. Note that Ryzen Threadripper chips have a higher base TDP of 280W to work with.
But as I said, the leaker also achieved a new overclocking record with the Intel Core i9-13900K CPU. While the Raptor Lake Core i7-13700K was pushed to 6.0 GHz, the flagship was pushed to 6.1 GHz on all 8 P.
The leaker reports that the single core CPU-z score was above 1000 points. There are also the numbers for all 5.5 GHz cores in CPU-z showing a 27% performance improvement over the standard chip, a 42% improvement over the Core i9-12900K, and a 40% improvement over the standard chip. compared to the Ryzen 9 5950X. The single core 6GHz score is slightly lower because there were some apps running on the back, but it should be around the same 980-990 points as the 13700K 6GHz score we saw yesterday.
Overall, this seems like very good multi-core performance for the upcoming Raptor Lake chips. We still want to wait for some detailed power and temperature figures, but one thing is for sure, in MT tasks, 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 go up against AMD’s Ryzen 7000 CPU lineup, which will also launch in fall 2022.
