    One of the photos mentioned "GDDR6 with ECC" IIRC.
    I'm still a little confused about which consumer GPU cards use the "built in" GDDR6-whatever error detection / correction (???) vs. have more width of data to provide the redundancy bits for correction or what. Does the 7900XTX have full "ECC" that is actually enabled / supported all the way between the RAM and the SW so that basically any normal error (e.g. N bits worth per X bits access width or more) will be detected & corrected either by a bus-retry or parity bits creating enough redundancy or whatever kind of packet coding they use in transport at the PHY/LINK level or what.
    Obviously I need to find a good article about how "ECC" works wrt. GDDR-n.

        Does this support hardware virtualization or it's still not expensive/pro enough for AMD?

          Only 16GB?

            AMD really needs to get more people working on ROCm. Support needs to be there across the line for all cards. That even workstation cards launch without ROCm support is embarrassing.

              So in the end, faster than 7500 but for 3 times the power consumption... So, no thanks for me. We have to save energy, that's our only option.

                For the price it's actually not bad. Better than NVIDIA's VRAM for this price range.

                  The 'Special Cases' section interests me, especially. Looks like a complicated situation, though?

                    A compute card with no support for their own compute stack. AMD is really pushing to new limits when it comes to neglecting their compute support.
