DDR5 “Sweet Spot” for Ryzen 7000 is 6000 MHz

Ever since AMD launched their Ryzen processors we’ve talked about the apparent “sweet spots” for memory frequencies. With Ryzen 3000 and Ryzen 5000 series we all know the real sweet spot for DDR4 has been 3600 MHz. Well now it looks like we now have details of 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, putting it at 6000 MHz.

As we know with AMD their Infinity Fabric should ideally run at a 1:1 ratio with the memory to deliver the best possible system performance and memory latencies. Of course with DDR memory running in dual-channel the actual clocks are only half of the memory speeds, so with 6000 MHz memory it is actually running at 3000 MHz. If 6000 MHz is the sweet spot at 1:1 that means the Infinity Fabric would be running at 3000 MHz, which would mean 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 max Infinity Fabric frequency of 3000 MHz and it looks like AMD has added a range of new memory and bus-related features to the AM5 platform.
