Asus Refreshes B450 Motherboards For Upcoming AMD Ryzen 5000 CPUs

UPDATED- 10/02/2020     10:44 AM IST

In a surprise move, as spotted by VideoCardz, Asus has refreshed its entire B450 product stack with several updates to stay them relevant for the present Ryzen 3000 series and new Ryzen 5000 series CPUs coming soon.

The main upgrades include higher memory OC support, a bigger firmware/BIOS chip (most likely 32MB), which allows more CPUs to be supported in BIOS without sacrificing BIOS quality or features, and upgraded connectivity like USB 3.2 Gen 2 ports rather than Gen 1. Finally, a few of the refreshed models include upgraded power delivery systems with more phases.

Taking a glance at the new ROG Strix B450-F Gaming II it’s received a replacement paint job. Upgrades include a replacement 8+4 phase power delivery system, which matches a number of Asus’ mid-range B550 boards so it should be ready to handle a 3950X without issue. there is a higher memory OC ceiling of 4400 MHz compared to 3600 MHz on the old board also . There’s an upgrade to all or any USB 3.1 ports from 3.1 to 3.2, and eventually BIOS flashback support.

The TUF Gaming B450-Plus II also gets an equivalent treatment, featuring an upgraded power delivery system, from 4+2 phases to 8+2 which may be a significant jump in VRM capability for the B450 Plus boards. this could allow you to run higher wattage Ryzen chips without encountering overheating VRMs. Asus has provided two M.2 slots, one Gen 3.0 and a further M.2 slot that runs at PCI-E Gen 2.0 x4 speeds, while not as fast as Gen 3.0, it’s still significantly faster than SATA3. All USB 3.1 ports are upgraded to USB 3.2. Aesthetically there are some changes to the planning , mainly within the chipset’s TUF logo being rotated 90 degrees and therefore the RGB lighting not says “TUF Gaming”.

Asus’ TUF Gaming B450M-Pro II has few changes from its vanilla counterpart, the first board already featured a superb excellent VRM solution and is in a position to support 4400 MHz memory frequencies out of the box. the sole changes are in connectivity, a further DisplayPort output and every one USB 3.1 ports being upgraded to three .2, plus one additional USB 3.2 port.
Asus’ TUF Gaming B450M-Plus II includes upgrades to the DRAM frequency from 3466 MHz to 4400 MHz, which may be a huge change for this board SKU. Besides that the sole change is (again) an upgrade from USB 3.1 ports to USB 3.2 ports and that is it.
Finally, we reach the PRIME boards, the Prime B450-A II has several beneficial upgrades including an enormous change within the memory department, DRAM frequencies can run up to 4400 MHz (from 3466 MHz), and memory capacity has doubled from 64GB to 128GB. The VRM remains unchanged with the exception of a heatsink added to assist cool things off. Still, i might limit my CPU choices to 65W TDP models or lower.

Lastly, the Prime B450M-K II gets minor upgrades including 4400 MHz memory frequency support just like the B450-A and a further HDMI output. Both PRIME boards get USB 3.2 support also .

The changes are a welcome sight to those which require an inexpensive AMD motherboard, capable of running future Ryzen processors without too many bells and whistles. the upper B450 boards just like the STRIX might be a troublesome sell, however, with entry-level and mid-range B550 boards already under $150. It all comes right down to PCI-E Gen 4.0 and the way badly you would like it, which may be a big deal now with new Gen 4.0 capable graphics cards and NVMe SSDs growing in popularity. Availability for these boards is unknown at this point .
