![]() ![]() ![]() Raptor Lake’s P-cores are codenamed Raptor Cove, and are designed with what Intel is calling their 3rd generation SuperFIN transistors, improved speed paths and a new dynamic prefetcher algorithm. So, are there anything that’s actually new with the Raptor Lake cores? Yes. Faster DDR5-5600 support (up from DDR5-4800 of Alder Lake).Larger 元 smart cache, up to 36MB for the i9-13900K (up from 30MB in the i9-12900K).The i9-13900K will feature a whopping 32MB of L2 (up from 14MB on the i9-12900K). Expanded 2MB L2 cache per P-core, and 4MB L2 cache per E-core cluster, more than doubling the total L2 cache of its predecessors.Expect to see 6P+8E for the i5-13600K and 6P+4E for the rest of the i5s. Intel will also extend the performance hybrid architecture to the entire i5 lineup for Raptor lake. Double the Efficiency Cores (E-core) of its Alder Lake counterparts with the i9-13900K having 16 E-cores, for a total processing capability of 24 cores (and 32 threads).Same number of Performance Cores (P-core) as its predecessors, but with faster boost clocks, up to 5.8GHz for the i9-13900K.If there is any thing you take away from this article, it should be these points. Let’s first take a look at the top level changes that will come to the desktop K-class CPUs before diving into some technical stuff. What’s new for Raptor Lake and performance hybrid architecture? Now, I used air quotes for merely in the last paragraph because as easy as it is to write off Raptor Lake as Alder Lake+, Intel managed to squeeze so much gains from these tweaks that they claim Raptor Lake’s performance matches or even exceeds the expectations of a microarchitecture generation gap. However, the underlying architecture and technology remains the same. Raptor Lake has more of everything compared to Alder Lake - faster P-cores, more E-cores, more L2 and 元 cache, and faster DDR5 support. However, unlike AMD’s brand new Zen 4 microarchitecture that’s now based on a 5nm process, Intel’s Raptor Lake is “merely” another refinement of their 10nm process node, also known as Intel 7, and the performance hybrid architecture that debuted with last generation’s Alder Lake chips. In the blue corner, Intel’s direct response to AMD’s Ryzen 7000 series is its own 13th Gen Core series of processors, codenamed Raptor Lake.
