Intel Raptor Lake with bigger cache
A newly leaked screenshot supposedly showing Intel 13th Gen Core ‘Cache configuration’ has been posted by OneRaichu.
There is really no way to tell if this is the flagship Raptor Lake CPU, so it does not make sense to throw SKU names at this point. What is clear though is that the alleged screenshot shows a combination of 8 ‘big’ cores and 16 ‘small cores’, which is a configuration of the upcoming Intel CPU.
Intel 13th Gen Core series is to feature a new Performance core microarchitecture called Raptor Cove. While the number of these cores will not change over a generation, each core is said to feature more cache. This would be confirmed by the following screenshot:
Here’s a reminder that 12th Gen Core “Alder Lake” series features 1280 KB of L2 cache and 3072 KB of L3 cache per each Golden Cove/Performance core. The hybrid architecture also features up to two clusters of four Gracemont/Efficient cores. Each of those clusters is connected to 2048 KB of L2 cache and 3072 KB of L3 cache.
A screenshot from CPU-Z software posted by OneRaichu shows the configuration of L1, L2 and L3 caches. It seemingly confirms that L2 cache (third row) will get 2MB per each ‘big’ core and 4MB per a cluster of small cores. This SKU would feature four such clusters and a combined number of 16 ‘small’ cores. In fact, the multiplier of ’16’ confirms exactly this number. Such configuration equals 32MB of L2 cache, and combined with 36MB of L3 it gives a total cache of 68MB, so 24MB more than Alder Lake.
Now, it appears.

Interestingly, a Raptor Lake successor codenamed “Meteor Lake” should offer a smaller 3MB L2 cache for a cluster of small (Crestmont) cores. However, we still do not know what configurations of desktop chips (if any) are planned. Although Intel has only showcased its mobile Meteor Lake chips, the company confirmed the architecture will scale up to 125W.
