GeForce RTX 4080 SUPER vs GeForce RTX 5070: In-Depth Breakdown
Performance: GeForce RTX 4080 SUPER vs GeForce RTX 5070
The GeForce RTX 4080 SUPER is significantly faster, around 22% 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 SUPER packs 10,240 CUDA cores versus 6,144 on the GeForce RTX 5070.
Price & Value
The GeForce RTX 5070 currently lists from $135,001 JPY, $202,717 JPY less than the GeForce RTX 4080 SUPER at $337,718 JPY. Despite being slower, the GeForce RTX 5070 offers the better performance-per-dollar (~105% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 5070 still sits about $134,452 JPY above its $549 JPY MSRP. The GeForce RTX 4080 SUPER still sits about $336,719 JPY above its $999 JPY MSRP.
Power & Efficiency
At 250W against 320W, the GeForce RTX 5070 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the GeForce RTX 4080 SUPER at 16GB versus 12GB on the GeForce RTX 5070 — that extra 4GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. The GeForce RTX 4080 SUPER's memory is also faster — 736 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 4080 SUPER or GeForce RTX 5070?
Choose the GeForce RTX 4080 SUPER 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.
