Intel's 13th Gen Raptor Lake CPUs Could Have Larger Cache Size

Intel only announced the 12th Gen Alder Lake chipsets months ago and at CES 2022, the company revealed more additions to the lineup. It's not easy for these companies to release new CPUs at a faster rate compared to smartphones that we're getting very often. To workaround with that, Intel has been working on increasing clock speed while AMD has been increasing cache.

In recent years, Intel's CPU cache sizes haven't increased much but according to a new leak, the 13th Gen Raptor Lake chipsets may be getting a larger cache size with an increase of up to 68MB. On Twitter, @OneRaichu mentioned that the "interesting" 68MB in question belongs to an Intel Raptor Lake processor. If the increase in cache size is true, this would mean that it would have a huge boost in overall CPU performance.

Another Twitter user, @Olrak29_ tweeted a diagram that explains the alleged core configuration. According to the diagram, each P-Core of the Raptor Lake chip has 2MB of L2 cache and 3MB of L3 cache. Meanwhile, the Gracemont core clusters, consisting of 4 E-Cores each, have 4MB of L2 cache and 3MB of L3 cache. As the Raptor Lake could have up to 8 P-Cores and four clusters of E-Cores, the cache size adds up to 68MB.

If the leaks are accurate, Raptor Lake’s L2 cache sizes will increase from 1.25MB to 2MB for each P-Core and from 2MB to 4MB for each E-Core cluster. While the L3 cache remains the same, the two extra Gracemont clusters simply increase their sizes to 36MB.
