In a development that will surprise no-one who knows computing history, it has been rumoured Intel's next-gen desktop CPUs, codenamed Arrow Lake, will contain a whole lot more cache memory. Like, potentially a 75% increase in total L2 cache for the top Arrow Lake CPU. And we've seen what a fat wad of cache can do for gaming performance, right?
Since introducing its hybrid core design with Alder Lake Intel has consistently increased the level of cache used, per core, in its processors. That's exactly where you'd expect it to go when you hit upon the dual limits of power and clock speed, and indeed it's where the entire industry has gone, too.
AMD has made a name for itself jamming a ton of fast cache memory onto both its processors and GPUs, with the X3D and Infinity Cache techniques of recent chip generations. Nvidia has been on the same track as well with the Ada Lovelace architecture. It is essentially utilising the twin benefits of a new process node, enabling higher clock speeds, and sticking a vastly larger amount of L2 cache into its GPUs to generate its gen-on-gen performance increases.
Likewise, Intel is reportedly going to add another 50% of L2 cache to the Performance cores of its upcoming Arrow Lake processors, with the older Alder Lake cores having 1.25MB, and each Raptor Lake core having 2MB. The rumours from HXL on Twitter (via Tom's Hardware) are based on a Bilibili message thread, and suggest that Arrow Lake will see 3MB of L2 cache per core.
If we're expecting the Arrow Lake chips on the Intel 20A process node to top out at the same eight Performance Core design, then you'll be getting a full 24MB for those big boi cores.
But Intel has doubled the number of its Efficient cores from Alder Lake to Raptor
