The compute fabric is also made faster by up to 900MHz. The Raptor Lake CPUs can now support DDR5 speeds of up to 5600MHz. Intel has also focused on the Memory side. Raptor Lake: Better Memory Latency & Bandwidth It seems like Intel has grouped the E-Cores with each group called a cluster and a cluster sharing an L2 cache among the cores. At the same time, the L2 cache is doubled from Alder Lake to Raptor Lake. However, Intel has increased the core count in addition to higher clock speeds compared to Alder Lake. The E-Cores are essentially the same “Gracemont” that we saw on Alder Lake. The clock speeds have been fine-tuned as well, with Core i9 13900k E-Cores reaching up to 4.3GHz, whereas the Core i5-13600K E-Cores are rated for up to 3.9GHz. The Core i5-13600K has a total of 8 E-Cores. Intel has upped the size of the E-Cores on the Raptor Lake CPUs. This would mean the IPC uplift coming from the new platform. Intel has mentioned that a single-threaded performance gain on the new desktop CPUs is 15%. This contributes to some nice gains in the turbo boost. Intel has managed to up the V/F curve with some fine tuning to go with a 50 mV reduction in iso-frequency and over 200 MHz iso-voltage. There is a 2MB cache per core with an L2P advanced algorithm for prefetching. Intel has introduced new performance cores dubbed “Raptor Cove” cores. This is not it, as we are seeing a +200MHz boost for Core i5-13600K and a +400MHz boost for Core i7 13700k CPUs. Intel has introduced up to a +600MHz boost in the high-end offer of Core i9 13900k, making it the fastest desktop processor. About I5-13600k Technology Raptor Lake: The Fastest Performance Core Intel is expected to release some 22 variants in this generation. Intel has introduced new “Raptor Cove” cores in the new desktop processors, which have larger cache sizes, higher IPC than the Alder Lake, and high clock speeds. Intel is continuing the hybrid architecture design introduced with the Alder Lake but with further refinements and advancements. The Core i5-13600K is among the options put forward to the users. Intel has successfully launched the Raptor Lake series desktop processors, termed as 13th generation.
