GeForce RTX 4070 SUPER vs GeForce RTX 3080: In-Depth Breakdown
Performance: GeForce RTX 4070 SUPER vs GeForce RTX 3080
The GeForce RTX 4070 SUPER is significantly faster, around 22% ahead of the GeForce RTX 3080. That gap is enough to move it up a tier: the GeForce RTX 4070 SUPER is comfortable at 4K with upscaling and native 1440p, while the GeForce RTX 3080 is better matched to 1440p.
Price & Value
The GeForce RTX 3080 currently lists from $387 GBP, $332 GBP less than the GeForce RTX 4070 SUPER at $719 GBP. Despite being slower, the GeForce RTX 3080 offers the better performance-per-dollar (~52% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 3080 is trading below its $699 GBP MSRP — a genuine deal. The GeForce RTX 4070 SUPER still sits about $120 GBP above its $599 GBP MSRP.
Power & Efficiency
At 220W against 320W, the GeForce RTX 4070 SUPER is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Ada Lovelace architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4070 SUPER carries 12GB versus 10GB on the GeForce RTX 3080. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 3080's memory is also faster — 760 GB/s versus 504 GB/s (320-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 4070 SUPER is roughly 4 years newer than the GeForce RTX 3080 (Ada Lovelace vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3080 or GeForce RTX 4070 SUPER?
Choose the GeForce RTX 4070 SUPER if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 3080 stretches your money further for only slightly lower performance.
