GeForce RTX 5090 vs Radeon RX 7900 GRE: In-Depth Breakdown

Performance: GeForce RTX 5090 vs Radeon RX 7900 GRE

The GeForce RTX 5090 is dramatically faster, around 122% ahead of the Radeon RX 7900 GRE. That gap is enough to move it up a tier: the GeForce RTX 5090 is comfortable at 4K and high-refresh 1440p, while the Radeon RX 7900 GRE is better matched to 4K with upscaling and native 1440p.

Price & Value

Right now the Radeon RX 7900 GRE starts at $1,246 GBP against $3,180 GBP for the GeForce RTX 5090. Despite being slower, the Radeon RX 7900 GRE offers the better performance-per-dollar (~15% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 7900 GRE still sits about $697 GBP above its $549 GBP MSRP. The GeForce RTX 5090 still sits about $1,181 GBP above its $1,999 GBP MSRP.

Power & Efficiency

The Radeon RX 7900 GRE pulls less power (260W vs 575W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5090 draws more overall but extracts more performance from each watt β€” plan for a sturdier power supply if you pick it. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.

VRAM & Future-Proofing

With 32GB against 16GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 7900 GRE's 16GB can fall short.

Features & Ecosystem

Beyond raw numbers, the Radeon RX 7900 GRE brings AMD FSR upscaling and strong rasterization value, while the GeForce RTX 5090 offers NVIDIA DLSS upscaling/frame generation and stronger ray tracing. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.

Which should you buy: Radeon RX 7900 GRE or GeForce RTX 5090?

Choose the GeForce RTX 5090 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 7900 GRE stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the GeForce RTX 5090 better than the Radeon RX 7900 GRE?
