GeForce RTX 4090 vs GeForce RTX 3070 Ti: In-Depth Breakdown
Performance: GeForce RTX 4090 vs GeForce RTX 3070 Ti
The GeForce RTX 4090 is dramatically faster, around 140% ahead of the GeForce RTX 3070 Ti. That gap is enough to move it up a tier: the GeForce RTX 4090 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 3070 Ti is better matched to 1440p. The GeForce RTX 4090 packs 16,384 CUDA cores versus 6,144 on the GeForce RTX 3070 Ti.
Price & Value
Right now the GeForce RTX 4090 starts at $95 BRL against $5,516 BRL for the GeForce RTX 3070 Ti. Because it's both faster and competitively priced, the GeForce RTX 4090 wins on performance-per-dollar by about 13902%. The GeForce RTX 4090 is trading below its $1,599 BRL MSRP — a genuine deal. The GeForce RTX 3070 Ti still sits about $4,917 BRL above its $599 BRL MSRP.
Power & Efficiency
The GeForce RTX 3070 Ti is the lighter draw at 290W against the GeForce RTX 4090's 450W, making it the easier card to power and cool. The GeForce RTX 4090 draws more in absolute terms but squeezes out more performance per watt, so budget for a beefier PSU if you go that route. Its more modern Ada Lovelace architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4090's 24GB (vs 8GB on the GeForce RTX 3070 Ti) gives it more room for 4K textures and memory-hungry creative or AI workloads. The GeForce RTX 4090's memory is also faster — 1,008 GB/s versus 608 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 3070 Ti or GeForce RTX 4090?
The GeForce RTX 4090 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 Ti if you find it at a steep discount.
