GeForce RTX 5090 vs GeForce RTX 3090: In-Depth Breakdown
Performance: GeForce RTX 5090 vs GeForce RTX 3090
The GeForce RTX 5090 is dramatically faster, around 156% ahead of the GeForce RTX 3090. 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 3090 is better matched to 1440p. The GeForce RTX 5090 packs 21,760 CUDA cores versus 10,496 on the GeForce RTX 3090.
Price & Value
The GeForce RTX 5090 currently lists from $798 EUR, $992 EUR less than the GeForce RTX 3090 at $1,790 EUR. Because it's both faster and competitively priced, the GeForce RTX 5090 wins on performance-per-dollar by about 475%. The GeForce RTX 5090 is trading below its $1,999 EUR MSRP — a genuine deal. The GeForce RTX 3090 still sits about $291 EUR above its $1,499 EUR MSRP.
Power & Efficiency
On power, the GeForce RTX 3090 is the gentler choice at 350W versus 575W. The GeForce RTX 5090 is more efficient per watt because it's faster, but its higher 575W draw means more heat and a bigger 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 5090 carries 32GB versus 24GB on the GeForce RTX 3090. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 5090's memory is also faster — 1,792 GB/s versus 936 GB/s (512-bit vs 384-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 5090 is roughly 5 years newer than the GeForce RTX 3090 (Blackwell vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3090 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 3090 if you find it at a steep discount.
