In November 2021, AMD officially launched a new version of the Zen3 processor, adding 3D V-Cache caching technology for the first time, of which the desktop version is the Ryzen 7 5800X3D, with an increase of 64MB cache, and the server version is the Milan-X Xiaolong series, with an additional 512MB cache.
Specifically, the Milan 7003 series originally had up to eight small chips inside, each with 32MB of L3 cache, for a total of 256MB.
The Milan-X 7003X series has an additional 64MB of L3 cache stacked on each chiplet, for a total of 512MB.
If you count the 4MB L1 cache and 32MB L2 cache, a 64-core Dragon has a terrifying 804MB cache, and the two-way is almost 1.6GB!
According to AMD's tests, more cache can greatly reduce the pressure on system memory bandwidth, and the same 16-core Milan-X, Milan, Synopsys VCS measured EDA RTL verification workloads, performance increased by up to 66%.
