Raptor Lake-S is rumored to have a total cache of 68MB
In fact, if you look back at the architecture of Intel and AMD in recent generations, you will find that both are increasing the cache in the CPU. AMD’s upcoming Ryzen 7 5800X3D processor stacks a 64MB SRAM vertically directly on the CPU core, tripling the L3 cache capacity. Intel’s 12th-generation Core has a significant increase in L2 and L3 cache capacity compared to the previous architecture, and a larger cache can indeed effectively boost IPC and game performance.
Intel’s next-generation processor, Raptor Lake, will further pile up the L3 cache, according to their product roadmap, this processor will be launched in the second half of this year, @Olrak29_ has drawn a rough block diagram of this processor, the desktop version of the Raptor Lake-S processor will have up to 8 P-Cores and 16 E-Cores, among them, the architecture of P-Core will be upgraded to Raptor Cove, and its L2 cache capacity will be increased from 1.25MB per core to 2MB. The E-Core is still Gracemont, but the shared L2 cache capacity per group has been increased from 2MB to 4MB.
As for the L3 cache capacity, each P-Core and a set of E-Cores are still 3MB, but due to the addition of two sets of E-Cores, the total capacity is increased from 30MB to 36MB. Raptor Lake’s L2 and L3 add up to a total of 68MB of total cache.
AMD’s Zen 4 architecture will also increase the cache capacity. It is reported that the L2 cache capacity of Zen 4 will increase from 512KB to 1MB, while the L3 cache capacity is still unclear. But referring to the current Zen 3D, it is not difficult for AMD to increase the L3 cache capacity.
