Intel Raptor Lake specs leak: 68MB of L2+L3 cache
Intel will release the 13th generation Core processor Raptor Lake this year. The current 12th-generation Core processor Alder Lake has up to 8 P-Cores and 8 E-Cores, while Raptor Lake will double the number of E-Cores, up to 24 cores and 32 threads, the P-Core architecture will be changed from the Golden Cove architecture to the Raptor Cove architecture, and the E-Core architecture will remain the same as the Gracemont.
Earlier news pointed out that Raptor Lake will further increase the cache of the processor. The top-level Core i9-13900K’s L2 and L3 caches add up to a total of 68MB. Now @OneRaichu has posted a screenshot of this processor in CPU-Z software, confirming this claim.
Raptor Lake’s P-Core L2 cache capacity will increase from 1.25MB per core to 2MB now. The shared L2 cache of each group of E-Cores is increased from 2MB to 4MB, and the L3 cache capacity is still 3MB for each P-Core and a group of E-Cores. However, due to the addition of two sets of E-Cores, the total capacity has increased from 30MB to 36MB, and the L2 and L3 add up to a total of 68MB of total cache.
The total L2+L3 cache capacity of the Intel Raptor Lake processor will increase by 55% compared to the current Alder Lake processor, which can provide lower latency than Alder Lake in some scenarios. The effect of increasing the cache can be seen from the evaluation of AMD Ryzen 7 5800X3D. Although AMD’s current 3D V-Cache can provide 32MB+64MB of L3 cache, the total capacity is dominant, but Intel has increased the faster L2 cache, and it is difficult to say who is better.
