A trio of Intel 13th Gen Raptor Lake (RPL) processors seem to have recently checked into SiSoft’s sysinfo and benchmarking tools. Prolific Twitter Technical Data Detective Tum Apisak spotted (opens in new tab) When highlight (opens in new tab) SiSoft database entries referring to Core i3-13100, i5-13400, and i9-13900 desktop CPUs. Of course, we’ve seen plenty of leaks and leaks regarding Raptor Lake’s top-end and upcoming flagship CPUs, so it’s interesting to see a more mainstream offering by Intel in the light of this example.
Tum_Apisak neatly collected the basic specs of each CPU from online charts. One important thing to take away from this is that the new Intel Core i3-13100 model is configured with performance cores (P cores) only. So it’s a very similar product to the previous (current generation, Alder Lake or ADL) Intel Core i3-12100 with 4C/8T. This is the configuration we expect to see on most entry-level 13th Gen CPUs, which are essentially slowed-down 12th Gen parts.
Conversely, the Core i5-13400 marks a significant departure from its ADL predecessor by adding several Efficiency-Cores (E-Cores) to the chip. Also, the Core i9-13900 (a close relative of the widely leaked Core i9-13900K) features twice as many E-Cores compared to its ADL predecessor.
Remember, Rator Lake data needs a bit of salt until confirmed by Intel.

The data Apisak unearthed also included various benchmark data. Each processor seems to have undergone various tests by users. However, they all did one specific test, which is why SiSoft recorded the “Processor Multimedia Score”, a test of iGPU processing performance. It also records the number of GPU compute units and the average clock speed.

The iGPU scores are interesting, but the number of compute units and clock speeds are not as expected. For example, his CU on the Core i5 is nearly double, but the GPU clock is much slower and he doesn’t deliver the nearly 10x performance boost compared to the Core i3, SiSoft said. Additionally, rumors suggest that Raptor Lake won’t make much of a difference in the iGPU stake compared to Alder Lake, offering just a few MHz of extra speed. So if you want to know how a particular 13th Gen Core Processor iGPU performs, look for reviews of the corresponding 12th Gen parts.
Intel is rumored to reveal extensive details about its Raptor Lake CPUs at the Intel Innovation event on Wednesday 28th September with a review on the same day. Pre-orders and sales will reportedly begin in mid-to-late October.
