SiSoftware Sandra outlines benchmarks. The SoC features 36 MB of unified L3 cache compared to Alder Lake's 30 MB. The SoC uses the latest IO and memory standards, including 5600 MT/s DDR5 and PCIe 5.0. Large P-cores have 2 MB of L2 cache per core and no AVX-512. 4 MB of L2 cache for a cluster of E-cores. 

Atom E-cores now have AVX/AVX2 functionality, a first. The author gathered appropriate tests to compare to Alder Lake model. Raptor Lake outperformed Alder Lake in ALU/FPU testing by 33 to 50%. Raptor Lake did this using 3.7 GHz P-Core and 2.76 GHz E-Core. The 13th generation design enhanced vectorized and SIMD scores by 5% to 8%. For now, we'd take these results with a grain of salt, you should await proper reviews.

Eight performance cores and sixteen efficiency cores comprise the 24-core Intel Core i9-13900 processor. This family of CPUs, according to SiSoftware, is built on upgraded Intel 7+ process technology, has a 20 percent larger L3 cache, and supports faster DDR5 memory of up to 5,600MT/s (vs. Alder Lake).

Additionally, the L2 cache has been enhanced for Raptor Lake and is now twice as large, enhancing core performance efficiency (2MB per core for large cores and 4MB per 4-core cluster on small cores). AVX-512 support is absent from Raptor Lake CPUs, as it has been totally deactivated (or not even present at all).

Overall, the ALU/FPU test findings demonstrate a 33 to 50 percent improvement over Alder Lake. Raptor Lake operates at 3.7 GHz for P-Core and 2.76 GHz for E-Core, whereas Alder Lake operates at 5.0 GHz for P-Core and 3.8 GHz for e-cores. Meanwhile, vectorized/SIMD studies reveal a performance increase of 5 to 8 percent over Alder Lake.

The debut of Intel 13th Gen Core desktop processors is anticipated within a few months. According to multiple reports, it will be a month before the NVIDIA GeForce RTX 40 is released, potentially in August or October.
