Can a FirePro V7900 work in tandem with a FirePro W7000?

[Bassinthemudd]

I have a Z820 Workstation that my son uses for gaming.

Specs are:

Dual Intel Xeon CPUs E5-2630 (6 core 12 thread) @ 2.30GHz

64 GB DDR3 Ram @1333Hz

AMD FirePro V7900 Graphics Card 2GB GDDR5

1TB Samsung SSD 860 Hard Drive

850w Power Supply

A recently installed game requires a more recent driver than my FirePro V7900 uses (version 15.201.2401.1010  2/16/2017). I searched through

the AMD website to find an older FirePro card that uses recent drivers.

I've ordered a FirePro W7000 which uses up to date drivers (version  20.Q4   11/10/2020). This card should be a nice little upgrade on it's own, but I'm curious if we'll be able to use the V7900 in tandem.  If yes, is the 850w power supply capable of powering this proposed configuration?

Thanks in advance for any input.

I'm pretty sure I've found the answer: No. Please confirm that this is correct.

I might consider another W7000 down the road.

if you mean can the cards work in tandem, then the answer is no crossfire requires that the cards be the same

next the w7000 is a much better card than the 7900, even two 7900's will not be any faster than the w7000

if a game does not run, it's usually because the video card does not support a necessary instruction such a vulkan or DX12 to name two of the most common ones if this is the case, you need to upgrade the video card usually as the above two items are hardware based

Thanks, very much.
