Fritzchens Fritz (opens in new tab) We have released a detailed die shot of Intel’s Core i9-13900K Raptor Lake processor with a total of 24 cores. The new CPU is noticeably larger than its 16-core Alder Lake predecessor. This is quite promising given the high core count and large cache of modern GPUs.
Intel’s latest desktop 13th Gen Raptor Lake has a die size of 252.65 mm^2, up from 215.25 mm^2 for desktop Alder Lake CPUs. Additionally, the new Raptor Lake processors feature 8 high-performance Raptor Cove cores and 16 energy-efficient Gracemont cores. In contrast, its predecessor only has 8 Golden Cove cores and 8 Gracemont cores. Additionally, the new chip features a total of 32MB of L2 cache and 36MB of L3 cache while its ancestor featured 14MB of L2 cache and 30MB of L3 cache.
As expected, the P cores are significantly larger than the Efficiency cores, each occupying 7.429 mm^2 of die space without L2/L3 caches, while the smaller cores without L2/L3 caches only occupy 1.58 mm^2. There is none. More detailed pictures are available at Fritzchens Fritz’s. flicker (opens in new tab).

On the other hand, both CPUs rely on the same Intel 7 (previously known as Intel 10nm Enhanced SuperFin) manufacturing technology, so the newer CPU should have a significantly larger die size and higher cost.
Along with the number of cores, larger cache, and larger die size. Raptor Lake has much in common with Alder Lake. Both CPUs use a ring bus interconnect to link the cores to graphics engines, input/output interfaces, and memory controllers. Additionally, the high performance cores are organized as an array of 8 cores and the energy efficient cores are grouped into quads. Intel’s flagship Core i9-13900K has all 24 cores enabled, while cheaper models have some cores disabled.
