The leak comes from @wxnod, who posted screenshots showing the specs of Intel’s Raptor Lake engineering samples. The CPU is labeled as a “Raptor Lake” chip and has an 8+16 core configuration. These include 8 P cores based on Raptor Lake and 16 E cores based on the Gracemont core architecture. This CPU has all of today’s modern instructions, with the exception of AVX-512, which Intel has removed from the consumer lineup.
The CPU’s P-Cores have 16MB of L2 cache (2MB per core), and the E-cores also have 16MB of L2 cache (4MB per group of 4 cores). This provides a total of 32MB of L2 cache, combined with the L3 cache for a total of 68MB of cache, which is rumored to be labeled “Game Cache”. for direct responseAMDRyzen 7000 CPUs have higher L3 caches, but Intel’s competitors also have their V-Cache parts, confirmed to be coming later this year.
In terms of clock speeds, the Intel Core i9-13900 Raptor Lake CPU is rated at 3.8-4.0 GHz. This is a non-K 65W model, so it will have a much lower clock speed, plus it’s an engineering sample as well, so the clocks are expected to be lower. The final clock speed should be the same as the Core i9-12900, which can be boosted to 5.0GHz. The same chip also appeared in the SiSoftware Sandra performance preview recently, demonstrating 50 percent more performance than the Alder Lake Core i9-12900, but the chip is also an early sample.
Intel’s 13th-generation Raptor Lake desktop CPUs are expected to launch later this year and will be powered by existing LGA 1700/1800 socket platforms, supporting both DDR5 and DDR4 DRAM.
