GeForce RTX 5090 vs GeForce RTX 4090: In-Depth Breakdown
Performance: GeForce RTX 5090 vs GeForce RTX 4090
The GeForce RTX 5090 is significantly faster, around 39% ahead of the GeForce RTX 4090. 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 16,384 on the GeForce RTX 4090.
Price & Value
Right now the GeForce RTX 4090 starts at $504 SEK against $8,076 SEK for the GeForce RTX 5090. Despite being slower, the GeForce RTX 4090 offers the better performance-per-dollar (~1053% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 4090 is trading below its $1,599 SEK MSRP — a genuine deal. The GeForce RTX 5090 still sits about $6,077 SEK above its $1,999 SEK MSRP.
Power & Efficiency
The GeForce RTX 4090 pulls less power (450W vs 575W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5090 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
With 32GB against 24GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 4090's 24GB can fall short. The GeForce RTX 5090's memory is also faster — 1,792 GB/s versus 1,008 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 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 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 4090 stretches your money further for only slightly lower performance.
