Why buy each?

AMD RX 7900 XTX

24GB GDDR6 — massive VRAM

More VRAM than any RTX 5000 card except the 5090. Unmatched for VRAM-hungry workloads.

Generation-end clearance

Superseded but strong value — clearance pricing makes this competitive with the RX 9070 XT at launch MSRP.

Mature RDNA 3 drivers

Over 2 years of driver optimization.

NVIDIA RTX 4090

24GB GDDR6X — more VRAM than RTX 5080

More VRAM than the RTX 5080 (16GB), relevant for AI workloads and 4K texture packs even in the Blackwell era.

Used market only

New retail units are scarce and priced above MSRP. The used market (eBay, local classifieds) is the only viable path to value.

Mature driver ecosystem

Over 3 years of driver optimizations make this one of the most stable GPUs available.
