7900XTX not 9700XTX which didn’t exist.

9070XT is RDNA4 not RDNA3 and steam machine has 28CU’s on RDNA3 which is same as RX7400 the bottom of the range RDNA3.

The 7900XTX has 84 and 24GB of VRAM.

This is a strictly entry level last gen GPU, don’t expect miracles.

The hardware is not good unless the price is very cheap.

As for the 7900XTX been enthusiast only in the sense it it was the top of the line from AMD it’s about 4080 in some areas and loses badly in others (ray tracing), price wise it wasn’t far of the 9070XT price wise at launch.

I have a 7900XTX I like it a great deal but the 4090/5080 and 5090 crush it and the 90’s are enthusiast both on price and perf.

I ended up with a 7900XTX because nvidia pissed me off on Linux one time too many otherwise I’d have gotten the 4090 but between kernel installs causing pain (nothing insurmountable) and them straight breaking power management for nearly a year on mature hardware, nah, AMD deserved the sale, they really do support Linux better.
