AMD Budget A620 motherboards will not support high-end Ryzen 7000 CPUs: Limited to 65W chips

Les cartes mères AMD Budget A620 ne prendront pas en charge les CPU Ryzen 7000 haut de gamme : Limitées aux puces de 65W

AMD quietly launched the A620 chipset for its Ryzen 7000 processors on Friday. With a starting price of $85, it will power the lowest-end AM5 cards for gamers on a budget. A620 motherboards will come with the same caveats as their 500 series predecessors, and then some. Any type of CPU-related overclocking will remain prohibited, including Precision Boost Overdrive and Auto-OC, while memory overclocking will not be allowed.

To improve adoption of its next-generation Ryzen 7000 processors, AMD has made the strategic decision to limit CPU support on A620 boards. Although the cheapest B650 cards are now available for less than $150, they are still more expensive than the lower-end B550/B550 offerings. The release of A620 motherboards at $85 should help tackle this part of the market.

Unfortunately, the A620 chipset will only support non-X Ryzen 7000 processors, as well as the 7800X3D which have a TDP of 65W. While the chipset will natively support high-end X-series CPUs, the VRMs on these cards will be designed for 65W SKUs to keep costs low.

The performance of Ryzen 9 CPUs will be similar to B650/X670 motherboards with Eco mode enabled. So while content creation performance will be affected, gaming should not be affected.

Compared to the B650 chipset, the number of PCIe lanes is only slightly lower, but we lose Gen 5 capabilities and USB 20Gbps support. There are sixteen PCIe Gen 4 lanes for the dGPU, four for the NVMe drive, and 32 in total. There are only two 10Gbps USB ports and two 5Gbps ports each.

At the time of writing, two A620 motherboards are available from Newegg, both from ASRock. They are sold at a price of 85 and 99 dollars. The first is equipped with one M.2 Gen 4 slot and two USB 3 ports, while the second has two M.2 ports and three USB 3 ports.

The A620 chipset is based on the PROM21 chipset, the same one that equips the B650 (PROM 21 x1) and X670 (PROM21 x2) motherboards. Instead of creating a new chipset for its low-end motherboards, AMD decided to use the existing variant.
