NVIDIA GeForce RTX 4090
Ada's monster still trades blows with anything short of the 5090: 24GB of GDDR6X and huge raster and RT muscle keep it a 4K powerhouse three years on.
Pros
- Still elite 4K and ray-tracing performance
- 24GB GDDR6X handles heavy workloads
- Very efficient when power-limited
- Mature Ada architecture and drivers
- Excellent CUDA compute for creators
Cons
- Discontinued, prices remain inflated
- No DLSS 4 Multi Frame Generation
- 450W draw and huge triple-slot coolers
Very good
