AMD Ryzen 7000 gaming benchmarks with current BIOS show no difference in performance between DDR5-6200 and DDR5-7400.

The first gaming benchmarks for AMD Ryzen 7000 CPUs with the latest AM5 BIOS, which should improve memory performance and support, have been published by Quasarzone and the results are not necessarily convincing. The latest AM5 BIOS is said to improve DDR5 memory support and overclocking on Ryzen 7000 CPUs, but gaming performance remains unchanged. The Quasarzone folks were quick to test the performance difference with faster memory, which is now possible thanks to the latest AGESA BIOS version 1.0.0.7b. This new BIOS should enable clock speeds north of DDR5-8000 and even further than DDR5-9000. While these numbers sound amazing, it remains to be seen if the higher speeds will make a difference in real-world applications.

For this demo, Tech Outlet has updated the ASUS ROG STRIX X670E-E Gaming WIFI to the latest 1514 BETA BIOS based on AGESA 1.0.0.7b firmware. A pair of KLEVV DDR5 Dual In-line Memory Modules (16GB x 2) were used for memory, operating in two configurations: DDR5-6200 (CL30-36-32-66) in 1:1 mode and DDR5-7400 (CL34-46-44-80) in 1:2 mode. Platform tested with both an AMD Ryzen 9 7950X and a Ryzen 7 780 chipset 0X3D V-Cache.

AMD Ryzen 7000 CPU performance on AM5 with DDR5-6200 and DDR5-7400 memory configurations:

Firstly, it was noted that the new BIOS now supports DDR5-7400 frequencies, which was not the case with AGESA 1.0.0.7a firmware. We’re glad to see that EXPO profiles are finally running on the AM5 at the speeds they were originally intended for. A number of 1080p games have been tested in the benchmarks, but the results show that higher frequency memory does not perform better than lower frequency memory on either chip.

AMD Ryzen 7 7800X3D CPU Performance on AM5 with DDR5-6200 and DDR5-7400 Memory:

The DDR5-7400 CL34 (1:2) configuration showed a slight drop in performance compared to the DDR5 6200 configuration in 1:1 mode. The performance differences were mostly within the fault tolerance range, but it turns out that games don’t necessarily benefit from faster memory. In this case, the memory ran in 1:2 mode, essentially cutting the IMC’s clock in half. In addition, the timings of higher frequency formation were also higher. Total bandwidth is not the only parameter that can be used to increase performance, but it can come in handy when running an APU where this aspect is more important.

But even if games don’t take advantage of the memory’s faster speeds, there are other applications that can, and that’s still a good thing for AMD’s AM5 platform and makers of motherboards that support high-speed DIMMs. The AGESA 1.0.0.7b BIOS is still in beta, so expect more improvements, but it’s a good start for AMD’s new Ryzen ecosystem.
