According to the tweet by @ 9550pro, Intel’s upcoming Raptor Lakei 7-13700K and i5-13600K engineering samples have been tested in numerous benchmark applications by Chinese content creators. bilibili.com. These applications significantly improve the performance of the new Raptor Lake parts and differ by 40% to 60% in CPU horsepower compared to the previous Alder Lake parts.
According to bilibili video, the test included a Core i7-13700K with 8P and 8E cores clocked up to 5.3GHz with a combination of DDR4-3600 and DDR5-5200. These results were directly compared to the Core i7-12700K running on the same memory kit.
For core i5-13600K results, the specification shows this chip with 6P and 8E cores at frequencies up to 5.1GHz operating at the same DDR4 and DDR5 frequencies as 13700K. The test was compared to its predecessor, the 12600K, using the same memory kit.

According to the benchmark results above, the 13700K shows a performance improvement of about 10% for single-threaded workloads. This is most noticeable on CPU-Z and Cinebench R20. But the multithreaded results share a different story. The performance of the 13700K and 12700KF has improved by 120-140%.
The 7-Zip results are particularly interesting, with 13700K completely dominating the compression results, with an average of 140.51% for Alder Lake DDR5 compared to baseline DDR4 results, compared to DDR5 testing. It is 164.84% better than its predecessor. This shows that Raptor Lake can take advantage of DDR5’s capabilities in memory-intensive applications compared to Alder Lake.

The i5-13600k results are similar to the 13700K, but with a slight bias towards chip multithreaded performance. In these results, single-threaded performance is slightly worst, with an average of 105-108%. However, the multithreaded performance is better than the 13700K than the previous model, with most benchmark results averaging close to 140%.
This is probably related to the closer frequency delta between 13600K and 12600K. In addition, the 13600K E-core count is far more influential than the 13700K. This is because both feature exactly the same number of core jumps compared to Alder Lake’s predecessor, but the 13600K has fewer P-cores available.
If the core clock of the Raptor Lake part is suspiciously low, a salt dose is recommended
Overall, these results should be taken with large amounts of salt. On the surface, these benchmarks appear to show that Raptor Lake will be a more multithreaded-focused architecture with slightly improved single-threaded performance.
However, I have heard reports of the opposite. RaptorLake focuses primarily on single-threaded performance as well as multi-threaded performance. Raptor Lake has the highest core frequency ever seen in a processor to date, and some models are believed to have a maximum official boost clock of 5.8GHz. Therefore, these benchmarks do not seem to give the big picture. The overwhelming core frequencies of 13700K and 13600K are only 5.1GHz and 5.3GHz.
Fortunately, however, these chips aren’t official product silicon, but perhaps some engineering sample. Traditionally, engineering chips have been characterized by lower inventory frequencies than current generation chips. Therefore, the fact that engineering samples with core clocks that exceed current generation (Alder Lake) chips have already been seen is a good indication that Raptor Lake has ample frequency headroom.
However, the very fast DDR5 performance of 13700K and 13600K on 7-Zip cannot be ignored. In this case, the compression score went through the roof compared to the 12700KF and 12600K. If this type of performance improvement also applies to other memory-intensive apps, the launch of Raptor Lake could lead more people to switch to DDR5. However, it will be known over time whether this will happen.
