This cache is a continuously addressable block due to the Ringbus interconnect making ring-stops at various physical segments of the cache. The 元 cache that's shared among the processor's P-cores and E-core clusters, is now enlarged to 36 MB, from 30 MB in the previous generation. Intel also made updates to the processor's uncore components. There are upgrades to even the hardware prefetchers of these cores. These are the same 'Gracemont' E-cores as previous-generation, but Intel has doubled the L2 cache that's shared in a 4-core Gracemont cluster, from 2 MB per cluster to 4 MB. This is achieved by doubling the E-core count to 16. 'Raptor Lake' has up to 8 P-cores, but the company has put in a lot of work in improving the contribution of E-cores to the processor's overall multi-threaded performance uplift. Intel's performance claims are backed by some impressive hardware changes despite the company sticking with the same Intel 7 (10 nm Enhanced SuperFin) foundry node as 'Alder Lake.' To begin with, the single-thread performance uplift comes from the new 'Raptor Cove' performance-core, which promises an IPC uplift over the previous-generation 'Golden Cove,' comes with more dedicated L2 cache of 2 MB per core (compared to 1.25 MB per core in the previous-generation) and significantly higher clock-speeds, going all the way up to 5.80 GHz.

Intel also claims to have outclassed the AMD Ryzen 9 5950X in multi-threaded performance, and the Ryzen 7 5800X3D in gaming performance.

With the new 13th Gen Core, Intel is broadly promising an up to 15% uplift in single-threaded performance, which has a bigger bearing on gaming performance and an up to 41% multi-threaded performance uplift over the previous-generation, when comparing the top Core i9-13900K with its predecessor, the i9-12900K. Likewise, 700-series chipset motherboards support older 'Alder Lake' processors. These processors are built in the same LGA1700 package as the previous generation 'Alder Lake,' and are backwards-compatible with 600-series chipset motherboards through a BIOS update. Intel today launched its 13th Gen Core 'Raptor Lake' desktop processors, and companion 700-series motherboard chipset.
