GeForce RTX 5080 vs GeForce RTX 5070: In-Depth Breakdown
Performance: GeForce RTX 5080 vs GeForce RTX 5070
The GeForce RTX 5080 is dramatically faster, around 45% ahead of the GeForce RTX 5070. That gap is enough to move it up a tier: the GeForce RTX 5080 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 5070 is better matched to 4K with upscaling and native 1440p. The GeForce RTX 5080 packs 10,752 CUDA cores versus 6,144 on the GeForce RTX 5070. The GeForce RTX 5080 also has more RT cores (84 vs 48) and more AI cores (336 vs 192), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
Right now the GeForce RTX 5070 starts at $539 GBP against $1,000 GBP for the GeForce RTX 5080. Despite being slower, the GeForce RTX 5070 offers the better performance-per-dollar (~28% better value), so budget-focused buyers should weigh it carefully.
Power & Efficiency
The GeForce RTX 5070 pulls less power (250W vs 360W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5080 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 12GB, the GeForce RTX 5080 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 5070's 12GB can fall short. The GeForce RTX 5080's memory is also faster — 960 GB/s versus 672 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 5070 or GeForce RTX 5080?
Choose the GeForce RTX 5080 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 5070 stretches your money further for only slightly lower performance.
