GeForce RTX 5090 vs GeForce RTX 4070: In-Depth Breakdown
Performance: GeForce RTX 5090 vs GeForce RTX 4070
The GeForce RTX 5090 is dramatically faster, around 170% ahead of the GeForce RTX 4070. That gap is enough to move it up a tier: the GeForce RTX 5090 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 4070 is better matched to 1440p. The GeForce RTX 5090 packs 21,760 CUDA cores versus 5,888 on the GeForce RTX 4070.
Price & Value
Right now the GeForce RTX 4070 starts at $11,871 BRL against $30,021 BRL for the GeForce RTX 5090. Because it's both faster and competitively priced, the GeForce RTX 5090 wins on performance-per-dollar by about 7%. The GeForce RTX 4070 still sits about $11,271 BRL above its $600 BRL MSRP. The GeForce RTX 5090 still sits about $28,022 BRL above its $1,999 BRL MSRP.
Power & Efficiency
The GeForce RTX 4070 draws just 200W versus 575W for the GeForce RTX 5090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 32GB against 12GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 4070's 12GB can fall short. The GeForce RTX 5090's memory is also faster — 1,792 GB/s versus 504 GB/s (512-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 5090 is roughly 2 years newer than the GeForce RTX 4070 (Blackwell vs Ada Lovelace), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 4070 or GeForce RTX 5090?
The GeForce RTX 5090 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 4070 if you find it at a steep discount.
