Yes, the 5700G supports graphics. No arguments there. My comment was that not all AMD CPUs have onboard graphics, so watch for that in your considerations. It looks like the "G" denotes graphics, and an "X" denotes non-graphics.
Good catch on the lack of PCIe 4.0 support, though. The motherboards listed above support PCIe 4.0, but I'm reading that an AMD CPU requires an X570 motherboard for PCIe 4.0. The above motherboards are all the B550 chipset, so I'm a bit confused on how they support PCIe 4.0 for AMD 5000 series, but apparently don't.
I'm not finding AMD CPUs that support PCIe 4.0 *and* onboard graphics, but here's a non-graphics CPU as an option:
AMD Ryzen 7 5800X - Vermeer 8-Core 3.8 GHz 105W CPU $309
One thing to consider with this CPU is the larger wattage draw (105W vs 65W). That means selecting an appropriate PSU as well, in the 700W to 750W range. A graphics card would also be required, which adds $150 to $200 for something decent. No HSF (heat sink / fan) is included with this CPU, so you would have to get one separately, such as liquid cooling that we discussed. That adds $100-ish to the build.
You CAN use the Samsung 980 PRO PCIe 4.0 SSD with the motherboards listed above, as well as with the AMD 5700 CPU. The con is that it will only work at PCIe 3.0 speeds. The PCIe 4.0 throughput is double that of PCIe 3.0, so it's a significant difference. However, it is backwards compatible.
BTW, a
Samsung 970 PRO M.2 2280 512GB PCIe 3.0 costs $165, so you're still better off with the 980 PRO that you bought. But, you could save a few bucks by downgrading to the
970 EVO PLUS M.2 2280 500GB PCIe 3.0, which is currently selling for $80. If it were me making the decision for myself, I'd keep the 980 PRO.
Hmm. I wonder if a B550 motherboard supports PCIe 4.0, only in that it will allow its use, but at the slower v3.0 speed. I dunno.
I'll look deeper into this and the available options.
