GeForce RTX 5070 vs GeForce RTX 3080: In-Depth Breakdown
Performance: GeForce RTX 5070 vs GeForce RTX 3080
The GeForce RTX 5070 is significantly faster, around 31% ahead of the GeForce RTX 3080. 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 3080 is better matched to 1440p.
Price & Value
Right now the GeForce RTX 5070 starts at $98,970 JPY against $105,185 JPY for the GeForce RTX 3080. Because it's both faster and competitively priced, the GeForce RTX 5070 wins on performance-per-dollar by about 40%. The GeForce RTX 5070 still sits about $98,421 JPY above its $549 JPY MSRP. The GeForce RTX 3080 still sits about $104,486 JPY above its $699 JPY MSRP.
Power & Efficiency
The GeForce RTX 5070 draws just 250W 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. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
With 12GB against 10GB, the GeForce RTX 5070 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 3080's 10GB can fall short. The GeForce RTX 3080's memory is also faster — 760 GB/s versus 672 GB/s (320-bit vs 192-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 3080 (Blackwell 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 5070?
The GeForce RTX 5070 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce RTX 3080 if you find it at a steep discount.
