Intel Core i9-13900 “Raptor Lake” Processor Gets a Preview

Intel is preparing to launch its 13th generation of desktop processors codenamed Raptor Lake. Succeeding Alder Lake, the 13th gen design will implement up to eight P-cores with 16 E-cores manufactured on Intel’s improved 7+ technology node. Today, we got a performance preview from SiSoftware that has collected SiSoftware Sandra database scores of Intel Core i9-13900 Raptor Lake-S processor. They present an overview of a few benchmarks. Firstly, the SoC features 36 MB of unified L3 cache versus 30 MB in Alder Lake. With DDR5 memory running up to 5600 MT/s and PCIe 5.0, the SoC features the latest IO and memory standards. The big P-cores now lack AVX-512 and feature 2 MB of L2 cache per core. We see 4 MB of L2 cache for a cluster of small E-cores. An exciting addition to E-cores is the AVX/AVX2 support, which is a first for Atom cores.

Regarding testing, the author has collected a few tests that seemed appropriate to compare to the equivalent Alder Lake model. Starting with ALU/FPU tests that benchmark basic arithmetic tasks, Raptor Lake delivered 33% to 50% improvement over Alder Lake. The Raptor Lake design achieved this with 3.7 GHz P-Core and 2.76 GHz E-Core frequency. In vectorized and SIMD tests, the 13th gen design showed only 5% to 8% improvement over the previous generation. For more benchmarks and accurate results, we have to wait for TechPowerUp’s test, which will be coming on the release day.
