GeForce RTX 3080 vs GeForce RTX 3070: In-Depth Breakdown
Performance: GeForce RTX 3080 vs GeForce RTX 3070
The GeForce RTX 3080 is significantly faster, around 30% ahead of the GeForce RTX 3070. Both cards sit in the same broad class, well suited to 1440p. The GeForce RTX 3080 packs 8,704 CUDA cores versus 5,888 on the GeForce RTX 3070. The GeForce RTX 3080 also has more RT cores (68 vs 46) and more AI cores (272 vs 184), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
Right now the GeForce RTX 3070 starts at $3,868 BRL against $4,875 BRL for the GeForce RTX 3080. Because it's both faster and competitively priced, the GeForce RTX 3080 wins on performance-per-dollar. The GeForce RTX 3070 still sits about $3,369 BRL above its $499 BRL MSRP. The GeForce RTX 3080 still sits about $4,176 BRL above its $699 BRL MSRP.
Power & Efficiency
The GeForce RTX 3070 draws just 220W 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.
VRAM & Future-Proofing
With 10GB against 8GB, the GeForce RTX 3080 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 3070's 8GB can fall short. The GeForce RTX 3080's memory is also faster — 760 GB/s versus 448 GB/s (320-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 3070 or GeForce RTX 3080?
The GeForce RTX 3080 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 3070 if you find it at a steep discount.
