GeForce RTX 5090 vs GeForce RTX 4070 SUPER: In-Depth Breakdown

Performance: GeForce RTX 5090 vs GeForce RTX 4070 SUPER

The GeForce RTX 5090 is dramatically faster, around 133% ahead of the GeForce RTX 4070 SUPER. That gap is enough to move it up a tier: the GeForce RTX 5090 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 4070 SUPER is better matched to 4K with upscaling and native 1440p. The GeForce RTX 5090 packs 21,760 CUDA cores versus 7,168 on the GeForce RTX 4070 SUPER.

Price & Value

Right now the GeForce RTX 4070 SUPER starts at $720 GBP against $3,180 GBP for the GeForce RTX 5090. Despite being slower, the GeForce RTX 4070 SUPER offers the better performance-per-dollar (~90% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 4070 SUPER still sits about $121 GBP above its $599 GBP MSRP. The GeForce RTX 5090 still sits about $1,181 GBP above its $1,999 GBP MSRP.

Power & Efficiency

The GeForce RTX 4070 SUPER draws just 220W versus 575W for the GeForce RTX 5090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.

VRAM & Future-Proofing

With 32GB against 12GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 4070 SUPER's 12GB can fall short. The GeForce RTX 5090's memory is also faster — 1,792 GB/s versus 504 GB/s (512-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.

Which should you buy: GeForce RTX 4070 SUPER 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 GeForce RTX 4070 SUPER stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the GeForce RTX 5090 better than the GeForce RTX 4070 SUPER?

The GeForce RTX 5090 is dramatically faster, roughly 133% ahead. The GeForce RTX 4070 SUPER is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the GeForce RTX 4070 SUPER or the GeForce RTX 5090?

The GeForce RTX 5090 is the better 4K option — it's comfortable at 4K and high-refresh 1440p, and its 32GB of VRAM helps with 4K textures.

Is the GeForce RTX 5090 worth the extra $2,460 GBP over the GeForce RTX 4070 SUPER?
