AMD has curiously taken a low-key method to launching its value-centric A620 motherboards, burying the total particulars of its A620 announcement late on a Friday evening, however the firm has lastly shared the total particulars and slide deck with us about its new vary of value-geared motherboards. To scale back pricing, the motherboards is not going to help the total vary of Ryzen 7000 processors at their full energy ranges. These boards additionally eradicate some options of the costlier AM5 motherboards, like overclocking and quicker USB connectivity, in change for a cheaper price level.
Regardless that AMD’s Ryzen 7000 lineup at the moment tops our listing of the perfect CPUs for gaming, the supporting AM5 motherboard platform and required DDR5 reminiscence have earned a status for egregiously excessive pricing. AMD even lately ran a promotion that gave you as much as $125 off in case you bought a chip, motherboard, and reminiscence, however that has expired at present.
That makes for a well-timed launch of AMD’s price range A620 platform with at the very least one motherboard that may retail for $85, however early indications level to pricing exceeding $100 for a number of new boards. Sadly, meaning the general A620 lineup will probably even be costlier than anticipated.
We do not have US pricing for many of the A620 motherboards, however whereas ASRock has one board for $85 and one other for $99 (opens in new tab), ASUS introduced EU pricing for three of its motherboards, with conversion to USD netting pricing of $151, $161, and $183. That is above what we anticipate for budget-class boards with decreased function units. We’ll observe up with extra US pricing as we obtain it, nevertheless it appears there’ll solely be a number of budget-class boards with this technology of the A-series motherboards.

AMD’s B-series motherboards are designed to help each Ryzen 7000 mannequin at its full TDP vary, typically leading to seemingly ridiculously overpowered boards for the lower-end chips. This additionally resulted within the excessive pricing for B-series motherboards in comparison with Intel’s competing chipsets, as Intel does not require its B-series motherboards to help the total peak energy limits of its extra power-hungry high-end chips. As such, distributors may reduce on energy supply (VRMs, and many others.) to cut back pricing.
The A620 motherboards are designed to help chips with a 65W TDP, that means fashions with a peak energy consumption of 88W (PPT). You possibly can set up chips with larger TDP rankings into an A620 motherboard, and it’ll boot if the BIOS helps it, however the chip is not going to function at its full peak energy consumption (PPT). This implies the highest-end chips will lose some efficiency in heavily-threaded purposes on account of VRM limitations, however AMD expects the decreased energy supply is not going to affect gaming a lot.
This coverage falls outdoors AMD’s customary AM5 coverage to this point, nevertheless it is smart. Larger-end chips aren’t a very good match for this class of lower-end motherboards, and the decreased energy supply will finally cut back pricing for lower-end builds. Moreover, this is identical method that Intel makes use of for its lower-end fare.
| Header Cell – Column 0 | 65W TDP | 105W TDP | 120W TDP (X3D) | 170W TDP |
|---|---|---|---|---|
| Socket Energy (PPT) Watts | 88W | 142W | 162W | 230W |
| Peak Present (EDC) Amps | 150A | 170A | 180A | 225A |
| Sustained Present (TDC) Amps | 75A | 110A | 120A | 160A |
General, the brand new motherboards will fall right into a cheaper price vary than their B-series counterparts, however as you may see within the full slide deck we have included above, there are different smart tradeoffs in options, with the boards stepping again from B650’s one USB 20Gbps and 6 10Gbps ports to 2 USB 10Gbps and two 5Gbps ports.
A620 supplies a x16 PCIe 4.0 connection however does not permit that to function in a 2×8 mode like B650. A620 additionally helps a direct-to-CPU x4 PCIe 4.0 connection for an M.2 SSD port, however does not have the choice for a PCIe 5.0 M.2 port like B650. It is a good step up from the x16 PCIe 3.0 supported on the previous-gen A520, although.
In fact, many bargain-basement A620 boards will solely have one M.2 slot, however A620 has the identical help for 4 SATA ports as B650. That is additionally two extra SATA ports than the previous-gen A520 chipset.
| Header Cell – Column 0 | A620 | A520 | B650 |
|---|---|---|---|
| CPU Graphics Assist | 1×16 PCIe 4.0 | 1×16 PCIe 3.0 | 1×16 or 2×8 PCIe 4.0 |
| CPU Storage Assist | 1×4 PCIe 4.0 | PCIe 3.0 | 1×4 PCIe 4.0 / 5.0 |
| CPU Chipset Uplink | 1×4 PCIe 4.0 | 1×4 PCIe 3.0 | 1×4 PCIe 4.0 |
| Overclocking Assist | No | No | Sure |
| Full TDP CPU Assist | 65W | Up to170W | As much as 170W |
As earlier than, the A620 chipset does not help handbook overclocking, so altering voltages and frequencies or auto-clocking by way of Precision Enhance Overdrive (PBO) is off-limits. Unsanctioned BCLK overclocking was attainable on at the very least one A520 board, however for now, it is anybody’s guess if that might be attainable with A620. The A620 motherboards help reminiscence overclocking by way of EXPO profiles as much as DDR5-6000, however we’re not sure if handbook reminiscence tuning is allowed.
From what we have gleaned, these motherboards use the Prominitory 21 (PROM21) chipset, the identical silicon used for AMD’s X670 and B650 motherboards. The AM5 platform leverages a brand new chiplet-based method for its chipsets, typically utilizing two PROM21 chips for higher-end chipsets, however A620 will solely embody one chip. Surprisingly, AMD did not develop lower-end chipset silicon for these price range boards, however re-use helps cut back design prices. It could possibly additionally ship value advantages from higher-volume manufacturing. We have now seen indicators of a PROM22 chip that may come later, however with the identical options as PROM21.
Motherboards are coming from all the traditional suspects, together with ASRock, ASUS, Gigabyte, MSI, and Biostar, however US pricing hasn’t been introduced for all the A620 boards but. We’ll observe up with extra particulars as they turn out to be out there.
