A trio of Intel 13th Generation Raptor Lake (RPL) processors has recently checked into SiSoft's sys info and benchmarking tools. Tum Apisak, best known for being a prolific Twitter tech data detective, spotted and highlighted SiSoft database entries for Core i3-13100, i5-13400, and i9-13900 desktop CPUs. A lot of leaks and spills are seen regarding Raptor Lake's top-end and upcoming flagship CPUs; thus, it is interesting to see some hopes that have been shown on the more mainstream offerings by Intel. 

Tum Apisak collected the CPUs' necessary specs from the online charts. One of the major things to be seen from this is that the new Intel Core i3-13100 model has a Performance-Cores (P-Cores) only configuration. Thus, this is a very similar offering to the previous (current gen, Alder Lake or ADL) Intel Core i3-12100, with 4C / 8T. It is the configuration that we want to see with the most entry-level 13th Gen CPUs that are essentially speed-bumped 12th Gen parts. 

Conversely, the Core i5-13400 displays some important differentiation from its ADL predecessor, by adding some Efficiency-Cores (E-Cores) to the chip. And the Core i9-13900 has double the number of E-Cores compared to its ADL predecessor. 

Remember, the Rator Lake data needs a pinch of salt till confirmation comes from Intel.

The data by Apisak also had a mishmash of benchmark data. Each processor seems to have been put to test by its user. However, they all did a particular test, so have a 'processor multimedia score' recorded by SiSoft, which is a test of the GPU processing performance and it also notes the number of GPU compute units and average clock speed.

The iGPU scores are quite interesting whereas, the compute unit counts and clock speeds are not up to the mark. Moreover, rumors claim that Raptor Lake will provide no significant changes vs. Alder Lake in the iGPU stakes - only a modest few MHz of extra speed. Therefore, if you want to have an idea about how a 13th Gen Core processor GPU might perform, search for the reviews of the corresponding 12th Gen part.
