AMD’s B550 Motherboards are now officially real, live, and available to purchase, and, along with them, comes a whole load of questions like “Do I need a B550 board?”, “Does it support PCIe Gen 4?”, and “what CPUs can I use?”, so in this video I want to explain all that and more, so lets jump into it. But first, if you haven’t already, consider subscribing for more videos every Monday, Wednesday and Friday!

AMD’s B series chipset has always been the ‘everyday’ chipset. The one that the vast majority of people should buy, but had a couple limitations. To start with, B series boards didn’t support PCIe Bifurcation – that means you couldn’t run 2 GPUs in crossfire or SLI, or say split your GPU lanes with PCIe SSD or network card, you’d have to run that through the chipset. The other limitation was that a lot of the B series boards were fairly low end, especially when it comes to power delivery, so running 8, 12 or 16 core CPUs wasn’t always the best on some, but now B550 is here, it (mostly) solves those problems!

All B550 boards now have the capability to bifurcate their direct-to-cpu lanes, meaning if you want to run SLI or crossfire, not that anyone does, you now can on B series boards. As for VRMs, they seem to be a lot beefier, depending on where you look. This Asus STRIX F board has an astonishing 12+2 phase DR Mos setup, and even the budget TUF PLUS board has an 8+2 setup, using SIC639 drivers rated for 50A each on both, an impressive setup for sure. 

So, what about that PCIe Gen 4 goodness? Well, it’s a bit complicated. Unlike X570 motherboards, only the lanes that connect directly to the CPU – shown in these diagrams – support PCIe Gen 4, not the link to the chipset. I asked MSI what is actually different on the hardware side, and the answer was “gen 4 approved PCIe slot/connector” and “approved trace routing” – making me a lot more confident in believing B550 is just B450 with a sticker.

Anyway, the point is you’ll be able to run 1 Gen 4 SSD in the top M.2 slot, along with technically up to 2 Gen 4 PCIe cards (at 8x each), then gen 3 for the rest, including any other M.2 slots the boards may have. 

CPU support is also a little tricky now. On B550 specifically, you are only able to use ‘current’ 3rd gen Ryzen CPUs. So, to make that clear, 1st and 2nd gen Ryzen chips WILL NOT WORK. DO NOT BUY B550 FOR A 2ND GEN RYZEN CPU. The reason they chose this is to make room for “future Ryzen Processors with the ‘Zen 3’ architecture”, but unless they are planning 2 more generations with Zen 3, I’m not sure why they wouldn’t support at least 2nd gen Ryzen here, but that’s what it is for now. 

Otherwise, everything is pretty similar. You’ve still got the usual added features, WiFi, and all that, although Asus have introduced an interesting one for their boards called AI MIC, it’s something I wasn’t able to test as their installer was broken for me, but they did send over some test clips, so see what you think.
