The A-Team on a budget: AMD Ryzen 7 7800X3D and A620 motherboard
YouTuber ‘minteger‘ had an opportunity to test AMD hardware featuring the latest available hardware.
This newly released hardware includes the 8-core Ryzen 7 7800X3D processor and A620 chipset motherboard. This combination of high-end gaming CPU and entry-level motherboard could become more common, in fact, it was one of the AMD’s recommended configurations. However, the A620 is not a premium design, so it shouldn’t be the first choice. The A620 is indented for an entry-level segment, especially when 65W Ryzen 7000s are considered.
However, some A620 motherboards come with more powerful VRMs and motherboard makers have confirmed those models will support higher than recommended TDP (65W). This is how one may end up with a system on a budget that is not held back by hardware.
Exactly this was tested by the content creator, who compared the 7800X3D CPU on two platforms: a high-end X670 and entry-level A620 designs. Both systems used DDR5-6000 memory because the A620 chipset does support EXPO (memory overclocking profiles). Minteger used Gigabyte’s A620 Gaming X motherboard with air-cooler, and he later compared this data with what was achieved on the X670 platform.
The dissimilarities start with gaming clock speeds, the X670 does indeed unlock more power for the CPU, which runs at 4.8 to 4.9 GHz. The same CPU on A620 platform sees 4.4 to 4.6 GHz clocks, which no doubt has an effect on performance. During Cinebench looped test, the CPU package power has oscillated around 81W with A620, while the X670 board has shown a near constant 95W. However, as shown below, this difference is minuscule in synthetic tests (5%), while it is even less in gaming (3%).
Despite minor difference, gamers that wish to have a peace of mind should probably look at a B650 chipset instead, which is a perfect middle ground between tested platforms. Some B650 motherboards are just $25-50 pricier, but in this case, one gets official support for 65W+ TDP CPUs and PCIe Gen5 for storage, should it ever be needed.
