If you’re looking to build a low-end to mid-range gaming PC or workstation with cheap, modern parts, it’s hard to recommend AMD’s Ryzen 7000 series processors. This is partly due to Intel’s CPUs offering more cores at similar prices, but motherboards with AMD’s socket AM5 remain stubbornly expensive and lack DDR4 memory support. , DDR5 RAM costs more to get.
That may change somewhat thanks to the new entry-level AMD A620 chipset that the company quietly announced last week. That’s not much below the price of his low-end Intel-based H610 and B660 motherboards, but it still requires DDR5 (for his DDR5-6000 recommended by AMD). For optimal Ryzen performance, the price premium is not double what you pay for the same amount of DDR4-3200).
How the A620 chipset stacks up against the high-end X670 and B650 options. Note the lack of CPU overclocking and PCIe 5.0 support.

Compared to X670 and B650 based motherboards, the connectivity of the A620 chipset is more limited. PCI Express 5.0 is not supported at all for either graphics cards or SSDs. Few GPUs and SSDs support PCIe 5.0 at this point, so it’s not a huge blow, but it’s a step back for future proofing. The processor offers enough PCIe 4.0 lanes for a GPU and one SSD However, the chipset only supports PCIe 3.0 speeds for additional SSDs. Also, the chipset supports fewer USB ports overall, and there are no 20Gbps USB ports.
Perhaps more importantly, the A620 chipset does not support any kind of processor overclocking, nor does it support Precision Boost Overdrive (PBO) or Curve Optimizer features for automatic overclocking or underbolting. This is in line with past AMD A-series chipsets and non-Z-series Intel chipsets, which also have limited support for overclocking features. AMD says memory overclocking will continue to be “supported on most devices.” [motherboard] model. ”
The A620 chipset has fewer (and slower) USB port options and uses PCI 3.0 speeds for additional M.2 storage slots. PCIe lanes for the CPU will continue to support a single PCIe 4.0 SSD slot and a PCIe 4.0 GPU slot.

These boards are the best choice for those who want to buy and install a regular old Ryzen 7600, 7700 or 7900 processor and use it without too many tweaks. AMD says high-wattage Ryzen chips like the X and X3D series will work as long as the motherboard’s BIOS supports it, but low-end voltage regulator modules (VRMs) can throttle peak performance. says there is
Case in point: ASRock offers two early A620 motherboards with similar names: A620-HDV/M.2 and A620-HDV/M.2+. Both motherboards look pretty much the same, but the M.2+ version has a significantly boosted VRM and improved cooling (see the area to the left of the CPU socket). ASRock has only evaluated low-end boards with 65W TDP processors, but the M.2+ version can handle 120W TDP CPUs.
AMD says more A620-based boards are coming from the usual suspects: ASRock, Asus, Gigabyte, MSI, and Biostar are all planning to release various A620 motherboard options. .
