Although the AMD Zen4 architecture will come later than expected, the improvement is definitely worth waiting for, such as the number of cores will be at least 96, for example, the memory will support 12 channels of DDR5. We know that AMD's existing Zen3 architecture Xiaolong 7003 series supports 8-channel DDR4-3200, with a maximum capacity of 4TB per channel.
Zen4 architecture will support DDR5 for the first time, the number of channels has been confirmed to increase to 12, coupled with the increase in DDR5 frequency, the bandwidth of a single system will exceed 460GB/s.
The latest exposure details the memory specification support of Zen4 Xiaolong: each channel can support 2 memory, a total of up to 24, a single support of up to 512GB 3DS RDIMM DDR5, the total capacity of a single system is a staggering 12TB!
However, the price is the frequency, which can only run to DDR5-4000 at this time, which is not yet the starting standard of the DDR5 specification.
Of course, for applications that require large memory capacity and bandwidth, the sacrifice of frequency is also acceptable.
If only 12 512GB are inserted, that is, 1 per channel, the total capacity can reach 6TB, and the frequency can also be 4800MHz, which is a more balanced choice.
If it is 12 256GB LRDIMM or 32GB RDIMM, you can run to the highest frequency supported by 5200MHz, with a total capacity of 3TB and 384GB, respectively.
