A hazy screenshot of a system running 64GB of DDR5-6400 RAM was posted on the Bilibili social media platform. So far, so regular, but the screenshot looks to be from the account of Toppc, a stalwart HWBot user and resident overclocker at MSI. Additionally, Twitter user HXL points out that the screen grab—while blurry—is noteworthy because it was taken from an AMD Ryzen 7000 Zen 4 (Raphael) PC system.
The screenshot was allegedly taken from a device running an AMD Ryzen 7000 CPU with the Zen 4 microarchitecture. It displays a portion of the screen with the CPU-Z programme active on the Memory tab. Toppc utilises the appropriate MSI dragon-skinned sysinfo and monitoring software.
The memory specifications that we can see here are not particularly impressive, but if the image is real and originates from an AMD Ryzen 7000 system, it is a first – a significant development in Raphael leak territory. The machine in the spotlight has 64GB of DDR5 installed, and it is DDR5-6400 with CL32 latency. The memory’s timings are CL-32-38-38-96-134, and it operates at a double data rate of 3,202.7 MHz.
The Bank Cycle Time (tRC) parameter field in CPU-memory Z’s tab is changed to the Row Refresh Cycle Time (tRFC) in the same tool on Intel-based systems, which seems to suggest this is an AMD machine. In other words, it is a confirmation that a DDR5-capable AMD system is being tested.
As far as we know, AMD Raphael CPU will only support DDR5 memory, but Raptor Lake, its largest rival, will continue to use platforms that support either DDR4 or DDR5 memory.
The speeds aren’t the most important part of the revelation, though, as AMD has already said that it had tested at DDR4-6400. Additionally, AMD recently said that, in part because of its new EXPO (EXtended Profiles for Overclocking) technology, it will provide outstanding memory overclocks with capable hardware.
According to the most recent benchmarks that were leaked, the future Ryzen 5 7600X could outperform a Core i9 12900K by more than 20% in single-core tests. Also anticipated for Fall are AMD Ryzen 7000 CPUs and 600-series chipsets.
