GeForce RTX 5090 vs GeForce RTX 5080: In-Depth Breakdown
Performance: GeForce RTX 5090 vs GeForce RTX 5080
The GeForce RTX 5090 is dramatically faster, around 49% ahead of the GeForce RTX 5080. Both cards sit in the same broad class, well suited to 4K and high-refresh 1440p. The GeForce RTX 5090 packs 21,760 CUDA cores versus 10,752 on the GeForce RTX 5080. The GeForce RTX 5090 also has more RT cores (170 vs 84) and more AI cores (680 vs 336), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
On price, expect to pay $11,500 BRL for the GeForce RTX 5080 versus $28,000 BRL for the GeForce RTX 5090. Despite being slower, the GeForce RTX 5080 offers the better performance-per-dollar (~63% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 5080 still sits about $10,501 BRL above its $999 BRL MSRP. The GeForce RTX 5090 still sits about $26,001 BRL above its $1,999 BRL MSRP.
Power & Efficiency
The GeForce RTX 5080 draws just 360W 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 16GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 5080's 16GB can fall short. The GeForce RTX 5090's memory is also faster — 1,792 GB/s versus 960 GB/s (512-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 5080 or GeForce RTX 5090?
Choose the GeForce RTX 5090 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 5080 stretches your money further for only slightly lower performance.
