In brief: the GeForce RTX 4080 is a high-end card from the Ada Lovelace generation (late 2022): 9,728 CUDA cores, 16 GB of GDDR6X on a 256-bit bus, DLSS 3.5 with frame generation, and a 750 W power supply recommended by NVIDIA. In 2026, it averages 117.5 FPS at 1440p and 67.5 FPS at 4K on native Ultra, according to Tom's Hardware, i.e. the level of an RTX 5070 Ti. An RTX 4080 gaming PC is therefore still very comfortable at 1440p and 4K with DLSS. To know whether you should still buy one, see our comparison with the RTX 50.
The RTX 4080, in a nutshell
Launched in November 2022, the RTX 4080 was one of NVIDIA’s first cards from the Ada Lovelace architecture, alongside the RTX 4090. It introduced DLSS 3’s frame generation, which changed how you play the most demanding games. In January 2024, NVIDIA complemented it with a slightly faster RTX 4080 SUPER.
We fitted them into our PCs at the time, like this ASUS TUF Gaming pictured in our workshop. Today, our high-end PCs have moved on to RTX 50, but the RTX 4080 remains a useful benchmark for positioning current cards.

RTX 4080 performance in 2026
| Tom's Hardware average | 1080p Ultra | 1440p Ultra | 4K Ultra |
|---|---|---|---|
| Rasterisation | 157.3 FPS | 117.5 FPS | 67.5 FPS |
| Ray tracing | 92.8 FPS | 68.4 FPS | 37.4 FPS |

What these figures mean: at 1440p, the RTX 4080 comfortably exceeds 100 FPS average, ideal for a 144 or 165 Hz display. At 4K, it’s around 67 FPS natively, and DLSS allows you to go significantly higher. Ray tracing is still expensive, as with all cards: that’s where DLSS and frame generation make the difference. To understand these technologies, see DLSS 4.5 vs FSR Redstone.
An RTX 4080 gaming PC in 2026: what should you choose?
The RTX 4080 was replaced by the RTX 50 in early 2025: you’ll mainly find it second-hand or in refurbished PCs. Its current equivalent is the RTX 5070 Ti, at the same performance level, with, in addition, DLSS 4 multi-frame generation. For more power at 4K, the RTX 5080 is about 15% ahead. On the AMD side, the RX 9070 XT matches it in rasterisation.
Our full analysis, including the cases where a used 4080 is good value, is in RTX 4080, RTX 5070 Ti or RTX 5080: should you still buy a 4080?.

FAQ: RTX 4080
How much memory does the RTX 4080 have?
16 GB of GDDR6X on a 256-bit bus, like the RTX 4080 SUPER.
Can the RTX 4080 play in 4K?
Yes: around 67 FPS on average in native 4K Ultra at Tom's Hardware, and much more with DLSS.
What’s the difference between the RTX 4080 and the RTX 4080 SUPER?
The SUPER has 10,240 CUDA cores versus 9,728, for a few more FPS, and was launched for less money ($999 vs $1,199).
Which current card is equivalent to an RTX 4080?
The RTX 5070 Ti from NVIDIA and the RX 9070 XT from AMD, at the same level in rasterisation.
What power supply for an RTX 4080 gaming PC?
NVIDIA recommends 750 W for a complete system.
