DDR5 “Sweet Spot” for Ryzen 7000 is 6000MHz

Ever since AMD launched their Ryzen processors, we’ve talked about the apparent “sweet spots” for memory frequencies. With the Ryzen 3000 and Ryzen 5000 series, we all know that the real sweet spot for DDR4 was 3600MHz. Well, it looks like we now have details on the sweet spot for DDR5 memory for AMD’s upcoming Ryzen 7000 series processors. This speed is actually 400 MHz higher than the maximum memory clock speed of DDR5-5600, which equates to 6000 MHz.

As we know at AMD, their Infinity Fabric should ideally work in a 1:1 ratio with the memory to deliver the best possible system performance and memory latencies. With DDR memory in dual channel, of course, the actual clocks are only half the memory speeds, so with 6000 MHz memory it’s actually running at 3000 MHz. If 6000MHz is the sweet spot at 1:1, it means the Infinity Fabric would run at 3000MHz, meaning the Ryzen 7000 series would offer better memory latencies than Intel’s Alder Lake and upcoming Raptor Lake processors.

Yuri Bubliy on Twitter has confirmed the maximum Infinity Fabric frequency of 3000MHz and it looks like AMD has added a range of new memory and bus-related features to the AM5 platform.
