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
Right now the GeForce RTX 5090 starts at $498 EUR against $1,377 EUR for the GeForce RTX 5080. Because it's both faster and competitively priced, the GeForce RTX 5090 wins on performance-per-dollar by about 313%. The GeForce RTX 5090 is trading below its $1,999 EUR MSRP — a genuine deal. The GeForce RTX 5080 still sits about $378 EUR above its $999 EUR MSRP.
Power & Efficiency
The GeForce RTX 5080 sips power at 360W next to the GeForce RTX 5090's 575W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU.
VRAM & Future-Proofing
The GeForce RTX 5090's 32GB (vs 16GB on the GeForce RTX 5080) gives it more room for 4K textures and memory-hungry creative or AI workloads. 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 5090 or GeForce RTX 5080?
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 5080 if you find it at a steep discount.
