Just hours ago a CPU-Z screenshot of an Intel Raptor Lake ES CPU appeared and the same CPU now appears to have been put through a full battery of benchmark tests, courtesy of Expreview. This upcoming 13th gen Core CPU from Intel is limited to a maximum clock speed of 3.8 GHz and as such, was tested against a Core i9-12900K that was clocked at the same speed, for a fair comparison. Both CPUs were used with an unknown Z690 motherboard, 32 GB of DDR5 5200 MHz memory with unknown timings and a GeForce RTX 3090 Founders Edition graphics card. According to Expreview, the 13th gen CPU is on average around 20 percent faster than the 12th gen CPU, although the extra eight E-Cores might have something to do with that in certain benchmarks.

In Sisoft Sandra 2021 the ES sample is as much as 51.5 percent faster in the double precision floating point test, which is the extreme outlier, but it's ahead by around 15-25 percent in most of the other tests. In several other tests, it's ahead by anything from as little as less than three percent to as much as 25 percent, with more multithreaded types of benchmarks seeing the largest gains, as expected. However, in some of the single threaded tests, Alder Lake is edging out Raptor Lake by 10 percent or more, for example in Pov-Ray and Cinebench. Most of the game tests favour Intel's 12th gen over the 13th gen ES sample, although it's possible that the limited clock speeds are holding back the Raptor Lake CPU. The two are either neck in neck or Alder Lake being ahead with anything from a couple of percent to almost nine percent. Keep in mind that it's still early days and everything from UEFI support to drivers will be improved before Raptor Lake launches later this year. There's also the limited clock speed which is likely to play a significant role in the final performance as well, but this does at least provide a first taste of what's to come.
