The Ryzen 9 7900X processors’ cache memory will be faster than current AMD CPUs.
The Ryzen 9 7900X test revealed that the bandwidth of the third-level cache was one and a quarter times greater than that of Ryzen 5000. It reaches 1400-1500 GB / s. This is in comparison with Core i9-12900K. However, the AMD novelty results are one-half to three times better, depending on which mode you choose.
However, the delay is only 10 nanoseconds which is twice as fast as Alder Lake but is still at the level of current generation Ryzen CPUs.
Remember that the Ryzen7000 will have up to 80 MB L2 + L3 cache. Future Ryzen7000 models will feature 3D V-Cache, which will increase the third-level cache by 64 or even 128MB.
