SiSoftware recently published a performance review of the upcoming Intel Raptor Lake Core i9-13900, based on aggregated results in its database. The Raptor Lake i9-13900 engineering sample handed in 50 percent better performance in ALU workloads, despite running at a low 3.7 GHz.

SiSoftware recently published a performance preview for the Raptor Lake Intel Core i9-13900. The results, aggregated from various test runs in SiSoft's data base indicate that Raptor Lake could deliver substantial IPC gains over Alder Lake. The Core i9-13900 is a Raptor Lake chip with 8 big Raptor Cove cores and 16 little cores. The engineering sample in the tests ran at 3.7 GHz in the benchmark runs but still managed to trounce both the Ryzen 9 5900X and the Core i9-12900 in a number of tests. 

In the ALU/FPU tests, the Raptor Lake chip actually handed in up to 50 percent higher performance, again despite the clockspeed disadvantage. It's important to note here that shipping Raptor Lake chips will be clocked substantially higher, in excess of 5 GHz. This means that real-life gaming performance could see a significant uplift on Raptor Lake.

As with Alder Lake, however, Raptor Lake chips will not support AVX-512 instructions, something AMD's "Raphael" chips will do. This could have tangible implications in terms of emulation performance. With Raptor Lake and AMD's Raphael chips set to arrive in a few months, it'll be interesting to see how the preview results here align with real-world numbers.
