The GeForce RTX 3080 packs 8,704 CUDA cores versus 5,888 on the GeForce RTX 3070. The GeForce RTX 3080 also has more RT cores (68 vs 46) and more AI cores (272 vs 184), strengthening its ray-tracing and AI-upscaling performance.

Price & Value

Right now the GeForce RTX 3070 starts at $297 GBP against $387 GBP for the GeForce RTX 3080. Despite being slower, the GeForce RTX 3070 offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The GeForce RTX 3070 is trading below its $499 GBP MSRP — a genuine deal. The GeForce RTX 3080 is trading below its $699 GBP MSRP — a genuine deal.

Power & Efficiency

The GeForce RTX 3070 draws just 220W versus 320W for the GeForce RTX 3080, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.

VRAM & Future-Proofing

With 10GB against 8GB, the GeForce RTX 3080 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 3070's 8GB can fall short. The GeForce RTX 3080's memory is also faster — 760 GB/s versus 448 GB/s (320-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.

Which should you buy: GeForce RTX 3070 or GeForce RTX 3080?

Choose the GeForce RTX 3080 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 3070 stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the GeForce RTX 3080 better than the GeForce RTX 3070?

The GeForce RTX 3080 is significantly faster, roughly 29% ahead. The GeForce RTX 3070 is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the GeForce RTX 3070 or the GeForce RTX 3080?

Neither is a dedicated 4K card; both are best at 1440p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the GeForce RTX 3080 worth the extra $90 GBP over the GeForce RTX 3070?

Only if you need the extra performance or features; on pure value the GeForce RTX 3070 comes out ahead.

Does the GeForce RTX 3080 have enough VRAM advantage to matter?

Its 10GB (vs 8GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.

Which is better for ray tracing, the GeForce RTX 3080 or the GeForce RTX 3070?

Both handle ray tracing, but the GeForce RTX 3080 has more RT cores, giving it better ray-tracing and AI-upscaling performance than the GeForce RTX 3070.
