Identical specs don’t help you choose, so “Differences only” hides them.
| Spec | RTX 5080 | RTX 5090 | Difference |
|---|---|---|---|
| Architecture | Blackwell | Blackwell | Same |
| Process node | 5 nm | 5 nm | Same |
Why this matters. Node names are marketing labels from each foundry. They hint at efficiency but are not a precise measurement. | |||
| Transistors | 45,600 M | 92,200 M | RTX 5090 · 46,600 M more (102%) |
| Release date | Jan 2025 | Jan 2025 | Same |

| Spec | RTX 5080 | RTX 5090 | Difference |
|---|---|---|---|
| FP32 compute | 56.34 TFLOPS | 104.9 TFLOPS | RTX 5090 · 48.56 TFLOPS more (86%) |
Data note. Peak theoretical throughput. Real game performance depends on drivers, architecture and resolution. | |||
| Shading units | 10,752 | 21,760 | RTX 5090 · 11,008 more (102%) |
Data note. Shader counts are not comparable between Nvidia and AMD architectures. | |||
| Base clock | 2,300 MHz | 2,010 MHz | RTX 5080 · 290 MHz higher (14%) |
| Boost clock | 2,620 MHz | 2,410 MHz | RTX 5080 · 210 MHz higher (9%) |
| Spec | RTX 5080 | RTX 5090 | Difference |
|---|---|---|---|
| VRAM | 16 GB | 32 GBMore | RTX 5090 · 16 GB more (100%) |
Why this matters. More VRAM holds larger textures and higher resolutions. Running out causes stutter; extra beyond what a game uses does nothing. | |||
| Memory type | GDDR7 | GDDR7 | Same |
| Memory bus | 256‑bit | 512‑bit | RTX 5090 · 256‑bit wider (100%) |
| Memory bandwidth | 960 GB/s | 1,792 GB/s | RTX 5090 · 832 GB/s more (87%) |

|---|---|---|---|
| Board power (TDP) | 360 W | 575 W | RTX 5090 · 215 W higher (60%) |
Why this matters. Higher board power means more heat and a bigger PSU requirement. It is not a quality score in either direction. | |||
| Card length | 304 mm | 304 mm | Same |
Why this matters. Check this against your case’s GPU clearance. Partner cards vary. | |||

How this comparison works
Every product in a category uses the same fields and units. Rows highlight a difference. A direction label such as “Lighter” or “More” appears only on fields where DuelVS’s methodology defines which way is generally preferable. Nothing here declares an overall winner.
