Why buy each?

NVIDIA RTX 4090

24GB GDDR6X — massive VRAM

More VRAM than the RTX 5080 (16GB), making it relevant for AI workloads and 4K texture packs.

Generation-end clearance pricing

Street prices have dropped significantly below $1599 MSRP, offering 5090-adjacent performance for less.

Mature driver ecosystem

Over 2 years of driver optimizations make this one of the most stable GPUs available.

AMD RX 9070 XT

16GB GDDR6 — VRAM advantage

4GB more than the RTX 5070 at the same price. Future-proofs for 1440p ultra and 4K textures.

FSR 4 with ML upscaling

AMD's first machine-learning upscaler, narrowing the gap with DLSS 4.

No vendor lock-in

AMD's open-source driver stack and FSR's open standard avoid proprietary ecosystem dependencies.
