The Ryzen 7 7700 and Ryzen 7700X are tested on the AMD X670E AM5 platform shown above in the table. We used the latest BIOS at the time of testing which was 1303. This is based on AGESA 126.96.36.199. We are using the motherboard’s current default BIOS settings. We have Resizable BAR ENABLED.
The CPUs are cooled by an MSI MEG CORELIQUID S360 AIO cooler. We used 32GB of G.SKILL Trident Z5 Neo DDR5 F5-6000J3038F16GX2-TZ5N (32GB 6000MHz @ 30-38-38-96) memory with EXPO Profile 1 enabled.
An NVIDIA GeForce RTX 4090 Founders Edition video card with driver GeForce 531.41 was common on both CPUs.
We are using a fresh install of Windows 11 Pro with the latest Windows Updates, including the 22H2 Fall 2022 update. We also have the latest chipset drivers installed which is 5.02.19.2221. We are using the BALANCED power profile in Windows Settings. Hardware Accelerated GPU Scheduling is ENABLED in Windows. Virtual Based Security (VBS) is DISABLED and Game Mode is ENABLED.
AMD Precision Boost Overdrive (PBO)
In our testing today we have also enabled PBO in the BIOS on the Ryzen 9 7900. For this we went into the BIOS and simply enabled PBO at the default settings, no further tweaking was done. We are therefore using the default PBO settings on this motherboard once you enable PBO. The graphs show “PBO ENABLED” which indicates the performance with PBO Enabled in the BIOS.
