GeForce RTX 4080 vs GeForce RTX 5070: In-Depth Breakdown
Performance: GeForce RTX 4080 vs GeForce RTX 5070
The GeForce RTX 4080 is significantly faster, around 20% ahead of the GeForce RTX 5070. Both cards sit in the same broad class, well suited to 4K with upscaling and native 1440p. The GeForce RTX 4080 packs 9,728 CUDA cores versus 6,144 on the GeForce RTX 5070.
Price & Value
Pricing has the GeForce RTX 5070 at $675 GBP, $1,227 GBP under the GeForce RTX 4080's $1,902 GBP. Despite being slower, the GeForce RTX 5070 offers the better performance-per-dollar (~136% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 5070 still sits about $126 GBP above its $549 GBP MSRP. The GeForce RTX 4080 still sits about $703 GBP above its $1,199 GBP MSRP.
Power & Efficiency
Power draw favors the GeForce RTX 5070 (250W vs 320W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4080 carries 16GB versus 12GB on the GeForce RTX 5070. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The GeForce RTX 5070 is roughly 3 years newer than the GeForce RTX 4080 (Blackwell vs Ada Lovelace), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 4080 or GeForce RTX 5070?
Choose the GeForce RTX 4080 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.
