The next generation of processors
Intel – the thirteenth – should see its cache increase considerably compared to Alder Lake.
The release of Alder Lake allowed Intel to take matters into their own hands and in many scenarios get ahead of AMD’s Ryzen 5000 series. The latter, however, has not said his last word and even before the release of the Zen 4 cores, he is preparing Ryzen 5000s equipped with the technology 3D Vertical Cache in order to increase this cache memory.
Raptor Lake from the end of 2022
While it is still very difficult to know precisely the impact of such a technique on the performance of the future Ryzen 7 5800X3D for example, this already seems to give Intel a few cold sweats.
According to the latest rumors relayed by TechPowerUp, Intel would actually have the idea of significantly boosting the second and third level caches integrated into its next generation of processors.
Following on from Alder Lake, this 13and CPU generation is already known as Raptor Lake and is expected to arrive in the second half of 2022. Yes, just a year after the release of Alder Lake.
Up to 68 MB L2+L3 cache
Intel does not raise the issue of the first level cache, but seems determined to review the other two levels. Thus, the most powerful Raptor Lake-S should be equipped with eight Raptor Cove cores (to replace the Golden Coves) and four Gracemont cores.
Raptor Cove should see its L2 cache increase to 2 MB compared to 1.25 MB for the Golden Cove cores of Alder Lake-S. For their part, the Gracemont cores operate with a cache shared between 4 cores: the L2 cache would be 4 MB per cluster against 2 MB today.
On the third level cache side, this is also a shared cache and on the Alder Lake-S processors, we could count on a maximum of 30 MB. In the case of Raptor Lake-S, we are talking about 36 MB In total, we would therefore go from 44 MB of L2+L3 cache on a Core i9-12900K to 68 MB on a Core i9-13900K. What will be the response from AMD / Zen 4?
