Intel Raptor Lake-S 24C/32T CPU with Arc A770 spotted on UserBenchmark with 4.6 GHz average boost and up to 32% higher multi-core performance compared to Core i9-12900K

Intel only gave a fleeting glimpse of the upcoming 13th gen Raptor Lake parts in action, but early samples have begun cropping up on various benchmarking sites. The latest such leak comes via User cough... cough... Benchmark, which shows a 24-core 32-thread Raptor Lake CPU in action. 

It is already known by now that Raptor Lake will see an increase in core counts from Alder Lake. While Alder Lake topped at 16 cores (8P + 8E) and 24 threads with the Core i9-12900K. Raptor Lake is expected to amp-up the core counts to 24 cores and 32 threads. Of these 24 cores, eight cores are Performance cores while 16 are Efficiency ones. 

According to the new UserBenchmark listing, the unnamed Raptor Lake-S part (Core i9-13900K?) has a base clock of 2.4 GHz and a boost of 4.6 GHz. The boost clock seems quite low given that a 16-core Ryzen 7000 prototype was demoed by AMD to boost between 5.2 GHz to 5.5 GHz. We've previously reported about Intel wanting to hit 5.5 GHz boosts this time and secure its single-core hegemony.

However, the benchmark listing indicates the Raptor Lake boost as the average boost clock that likely includes both P and E cores, so we should still be able to see higher frequencies with the P-cores alone notwithstanding the fact that this could be an engineering sample in all likelihood. The system also appears to be using 32 GB of DDR5-4800 memory — we expect faster DDR5 memory to be available by the time Raptor Lake hits market. 

The other interesting find from the benchmark is the mention of an Arc A770 Alchemist GPU. The Arc A770 seems to be the main limiting factor that is affecting the benchmark scores for this Raptor Lake system. That being said, the benchmark doesn't seem to be fully compatible with this card yet as it is able to detect just 1 GB of VRAM.

Apart from this preliminary info, there's not much that can be gleaned from the benchmark entry itself. Compared to a Core i9-12900K system, however, the Raptor Lake configuration in question ties with an average bench score of 114%. That being said, the multi-core performance seems to be up to 32% higher compared to the Core i9-12900K owing to the higher core/thread count.

While significant performance bumps over Alder Lake are being speculated with Intel's upcoming dinosaur of a CPU, the present comparison should still be taken with a big pinch of salt.
