GeForce RTX 5070 vs GeForce RTX 3070: In-Depth Breakdown
Performance: GeForce RTX 5070 vs GeForce RTX 3070
The GeForce RTX 5070 is dramatically faster, around 70% ahead of the GeForce RTX 3070. That gap is enough to move it up a tier: the GeForce RTX 5070 is comfortable at 4K with upscaling and native 1440p, while the GeForce RTX 3070 is better matched to 1440p. The GeForce RTX 5070 packs 6,144 CUDA cores versus 5,888 on the GeForce RTX 3070.
Price & Value
The GeForce RTX 3070 currently lists from $297 GBP, $241 GBP less than the GeForce RTX 5070 at $538 GBP. Despite being slower, the GeForce RTX 3070 offers the better performance-per-dollar (~6% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 3070 is trading below its $499 GBP MSRP — a genuine deal.
Power & Efficiency
On power, the GeForce RTX 3070 is the gentler choice at 220W versus 250W. The GeForce RTX 5070 is more efficient per watt because it's faster, but its higher 250W draw means more heat and a bigger PSU. 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 5070 carries 12GB versus 8GB on the GeForce RTX 3070. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 5070's memory is also faster — 672 GB/s versus 448 GB/s (192-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 5070 is roughly 5 years newer than the GeForce RTX 3070 (Blackwell vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3070 or GeForce RTX 5070?
Choose the GeForce RTX 5070 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.
