Nvidia GeForce RTX 5080 (16GB)
A solid generational step over the 4080 at $999, still capped at 16GB of VRAM.
Where it wins, where it doesn't
Pros
- Solid generational gain over the 4080
- Much better cost per frame than the 5090
- Strong for rendering and video work
Cons
- 16GB VRAM — no more model headroom than a 5070 Ti at two-thirds the price
- Cannot run 70B-class inference
- Expensive for what it adds over the tier below
