GeForce RTX 4090 vs GeForce RTX 5070 Ti: In-Depth Breakdown
Performance: GeForce RTX 4090 vs GeForce RTX 5070 Ti
The GeForce RTX 4090 is significantly faster, around 31% ahead of the GeForce RTX 5070 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 5070 Ti is better matched to 4K with upscaling and native 1440p. The GeForce RTX 4090 packs 16,384 CUDA cores versus 8,960 on the GeForce RTX 5070 Ti.
Price & Value
Right now the GeForce RTX 4090 starts at $95 BRL against $8,638 BRL for the GeForce RTX 5070 Ti. Because it's both faster and competitively priced, the GeForce RTX 4090 wins on performance-per-dollar by about 11861%. The GeForce RTX 4090 is trading below its $1,599 BRL MSRP — a genuine deal. The GeForce RTX 5070 Ti still sits about $7,889 BRL above its $749 BRL MSRP.
Power & Efficiency
The GeForce RTX 5070 Ti sips power at 300W next to the GeForce RTX 4090's 450W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Blackwell 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 16GB on the GeForce RTX 5070 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 896 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 5070 Ti is roughly 3 years newer than the GeForce RTX 4090 (Blackwell vs Ada Lovelace), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 4090 or GeForce RTX 5070 Ti?
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 5070 Ti if you find it at a steep discount.
