I’ve seen reports that the B580 may have lower performance with non-newest CPUs (possibly related to how ReBar being off can lower performance). Some of the options I see for that are also PCIe x8 as well.
I’m also on Linux, and from what I’ve heard it’s a bit behind there compared to the already expected beta-test. I mean, unless things (on either platform) have improved in the last 5 months.
Even if so, PCIe 5.0 x8 connection so it’s probably less useful for older systems with PCIe 3 (or even PCIe 4) which many on a budget will want to keep using.
Likely will have the issue (that B580 has) with older/weaker CPUs as well though that might be more of a gaming thing not sure about workstation use… I mean if it is a bandwidth issue with the architecture itself (with a CPU not being able to saturate the data for whatever reason) maybe.
