GeForce RTX 4090 vs GeForce RTX 4080 SUPER: In-Depth Breakdown
Performance: GeForce RTX 4090 vs GeForce RTX 4080 SUPER
The GeForce RTX 4090 is significantly faster, around 29% ahead of the GeForce RTX 4080 SUPER. 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 4080 SUPER is better matched to 4K with upscaling and native 1440p. The GeForce RTX 4090 packs 16,384 CUDA cores versus 10,240 on the GeForce RTX 4080 SUPER. The GeForce RTX 4090 also has more RT cores (128 vs 80) and more AI cores (512 vs 320), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
On price, expect to pay $18,959 SEK for the GeForce RTX 4080 SUPER versus $35,000 SEK for the GeForce RTX 4090. Despite being slower, the GeForce RTX 4080 SUPER offers the better performance-per-dollar (~44% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 4080 SUPER still sits about $17,960 SEK above its $999 SEK MSRP. The GeForce RTX 4090 still sits about $33,401 SEK above its $1,599 SEK MSRP.
Power & Efficiency
The GeForce RTX 4080 SUPER draws just 320W versus 450W for the GeForce RTX 4090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 24GB against 16GB, the GeForce RTX 4090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 4080 SUPER's 16GB can fall short. The GeForce RTX 4090's memory is also faster — 1,008 GB/s versus 736 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 4080 SUPER is roughly 2 years newer than the GeForce RTX 4090, so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 4080 SUPER or GeForce RTX 4090?
Choose the GeForce RTX 4090 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 4080 SUPER stretches your money further for only slightly lower performance.
