AMD Ryzen 7 7800X3D with A620 performance test
A short while ago, AMD discreetly introduced the A620 chipset, further reducing the cost of building an AM5 platform, with MSI and Gigabyte products already hitting the market. Although its expandability is somewhat limited, it sufficiently satisfies a substantial portion of users.
For some gamers, pairing a Ryzen 7000X3D series processor with an A620 motherboard may be an appealing option. Processors featuring 3D Vertical Cache (3D V-Cache) technology are not designed for overclocking, and their power requirements are even lower than some models with an “X” suffix, imposing minimal demands on the motherboard power supply. AMD claims that the A620 motherboards target 65W processors, and higher TDP models may experience performance constraints. Nevertheless, numerous manufacturers maintain that their A620 motherboards fully support Ryzen 7000X3D series processors without any issues.
Recently, Twitter user @harukaze5719 tested an AMD Ryzen 7 7800X3D processor with Gigabyte’s A620M GAMING X motherboard and compared it to an X670 motherboard. Both configurations employed EXPO and DDR5-6000 memory.
The results reveal that the X670 motherboard indeed allows the processor to unleash its full potential, with the distinction lying in frequency. On the X670 motherboard, frequencies hover around 4.8 to 4.9GHz, while they drop to 4.4 to 4.6GHz on the A620 motherboard. In Cinebench tests, the A620 motherboard’s CPU power fluctuates around 81W, while the X670 motherboard remains stable at 95W.
Although there are differences between the A620 and X670 motherboards, the actual test scores only diverge by 5%, and the disparity in gaming is even smaller at 3%.
