Expreview has released a full performance preview just a few hours after the Intel Core i9-13900 Raptor Lake CPU was discovered.
In multi-Threaded benchmarks, Intel Core i9-13900K ''Raptor Lake'' ES CPU is 20% faster than Core i9-12900K ''Alder Lake.''
The Intel Core i9-13900 ''Raptor Lake'' CPU that was tested is a science experiment similar to that we previously thought. It has an 8+16 core configuration. These include 8 P-Cores based on the Raptor Cove and 16 E-Cores based on the Gracemont core architecture.
The Core i9-13900 Raptor Lake CPU has a clock speed that is expected to be lower thanks to 16 MB of L2 cache for the P-Cores (2 MB per core) and 16 MB of L2 cache for the E-cores too (four MB per cluster of four cores). This is a non-K 65W component, indicating that the CPU will carry a clock speed that is similar to that of the other, but clocks are expected to be lower.
Both the Intel Core i9-13900 ''Raptor Lake'' and Core i9-12900K ''Alder Lake'' CPUs were tested on the Z690 platform with a pair of G.Skill DDR5-5200 memory and an NVIDIA GeForce RTX 3090 graphics card. As such, clock speeds shouldn''t be as low as the final chip. Expreview was able to set the Core i9-12900K at 3.8 GHz across all cores
The performance of Intel''s Raptor Lake Core i9-13900 CPU is significantly higher than the Alder Lake Core i9-12900K chip, which includes an optimized BIOS and a greater TDP limit. However, the Raptor Lake CPU''s clock speeds aren''t stable in multi-threading tests, although the 50% higher core count is boosted the performance by 20%, while the final retail chips should provide even better performance.
The Intel Core i9-13900 is mostly on the same level as the Core i9-12900K, but the differences are within the margin of error. With that being said, Raptor Lake CPUs are expected to launch later this year and will be supported by the existing LGA 1700/1800 socketed platforms with both DDR5 and DDR4 DRAM support.
