Intel Raptor Lake with more cache
A recently leaked screenshot purporting to show the Intel 13th Gen Core “cache configuration” was posted by A Raichu.
There’s really no way to tell if this is Raptor Lake’s flagship processor, so it doesn’t make sense to throw out SKU names at this point. What is clear though, is that the purported screenshot shows a combination of 8 “big” cores and 16 “small cores”, which is a configuration of Intel’s upcoming processor.
The Intel 13th Gen Core series is to feature a new Performance core microarchitecture called Raptor Cove. Although the number of these cores will not change over the course of a generation, each core is expected to carry more cache. This would be confirmed by the following screenshot:

Here is a reminder that the 12th Gen “Alder Lake” series includes 1280 KB of L2 cache and 3072 KB of L3 cache for each Golden Cove/Performance core. The hybrid architecture also includes up to two clusters of four Gracemont/Efficient cores. Each of these clusters is connected to 2048 KB of L2 cache and 3072 KB of L3 cache.
A CPU-Z software screenshot posted by OneRaichu shows the configuration of the L1, L2 and L3 caches. This apparently confirms that the L2 cache (third row) will get 2MB per each “big” core and 4MB per group 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 that number. Such a configuration equates to 32MB of L2 cache, and combined with 36MB of L3 gives a total cache of 68MB, which is 24MB more than Alder Lake.
Interestingly, a Raptor Lake successor named ‘Meteor Lake’ is expected to offer a smaller 3MB L2 cache for a cluster of small cores (Crestmont). However, we still don’t know what desktop chip configurations (if any) are planned. Although Intel only showcased its Meteor Lake mobile chips, the company has confirmed that the architecture will scale up to 125W.
