Comprehensive die images of Intel’s Core i9-13900K Raptor Lake processor, which has 24 total cores, have been shared by Fritzchens Fritz(opens in new tab). With 16 cores, the new CPU is substantially larger than its Alder Lake predecessor, which is to be expected given the new GPU’s greater core count and bigger cache.
The die size of Intel’s most recent top-of-the-line 13th Generation Raptor Lake CPU for desktops is 252.65 mm2, up from 215.25 mm2 for Alder Lake CPUs. Eight Raptor Cove cores with high performance and 16 Gracemont cores with low energy consumption are also included in the new Raptor Lake CPU. Its predecessor, however, only had eight each of the Golden Cove and Gracemont cores. Additionally, the new chip has a total of 36MB of L3 cache and 32MB of L2 cache, compared to its ancestor’s 14MB of L2 cache and 30MB of L3 cache.
P-cores, as expected, is much bigger than Efficiency cores; each one takes up 7.429 mm2 of die area without L2/L3 caches, compared to 1.58 mm2 for the smaller core. In-depth images can be seen on Fritzchens Fritz’s Flickr.
The newer CPU should have a significantly larger die size and cost more because both rely on the same fabrication technique, Intel 7 (formerly known as Intel 10nm Enhanced SuperFin).
Raptor Lake and Alder Lake have a lot of characteristics, other than the core count, larger caches, and larger die size. Both CPUs connect their cores to the graphics engine, input/output interfaces, and memory controller using a ring bus interconnect. Additionally, the energy-efficient cores are arranged into quads, and the high-performance cores are arranged into an array of eight cores. All 24 cores are enabled on Intel’s top-tier Core i9-13900K, however, some of the cores are disabled on less expensive variants.
