Some supposed results of the possible AMD Raphael desktop processors, of the Zen 4 Ryzen architecture; have been featured on the MilyWay @ Home project website. These results have revealed 8 and 16 core processors.
These CPUs are believed to be the first in the Ryzen 7000 series , and news about these processors surfaced thanks to @BenchLeaks on Twitter. While these initial listings don't reveal the performance levels offered by AMD's Ryzen 7000 series processors , they appear to confirm that AMD's Zen 4 Ryzen 7000 processors feature 1024 KB of L2 cache per core, which would be double that of the Zen 3 chips.

If these tests are confirmed, it would represent an architectural improvement for AMD's Zen 4 CPU cores , allowing them to store more data in AMD's core caches, which have lower latency than Zen's L3 cache and system memory. Data from lower-level caches is retrieved faster than data from higher-level caches or system memory, reducing the amount of time a processor can remain idle. Having more L2 cache will allow them to store more data on the core and act upon it without delay, further increasing system performance by reducing CPU idle time, assuming the latency of this expanded cache remains the same.
With the Ryzen 5800X3D , AMD is increasing the size of its processor's L3 cache to achieve similar performance goals. A larger L3 cache allows more data to be stored on the chip, and that data can be fed to the CPU cores more quickly to accelerate many workloads. This change reduces the amount of data that needs to be retrieved from system memory and speeds up gaming workloads by allowing data to reach the CPU cores faster.
With the 8-core 16-thread and 16-core 32-thread samples shown, AMD seems to keep the number of cores of the Ryzen CPU unchanged in Zen 4. It could also show a new 24-core model, but that would be a very high-end CPU for consumers and enthusiasts.
