In a typical game at high settings, the RTX 5080 is about 15% faster than the RTX 4080 SUPER. Both are sold with 16 GB of graphics memory.
A faster graphics card only shows its lead when the processor can prepare the extra frames. How much more the RTX 5080 delivers than the RTX 4080 SUPER, with common processors:
| Processor | 1080p | 1440p | 4K |
|---|---|---|---|
| Ryzen 5 3600 | No gain | No gain | +10% |
| Ryzen 5 5600 | No gain | No gain | +15% |
| Core i5-12400 | No gain | No gain | +15% |
| Ryzen 5 7600 | No gain | No gain | +15% |
| Core i5-14600K | No gain | +15% | +15% |
| Ryzen 7 9800X3D | No gain | +15% | +15% |
| Any processor fast enough | +15% | +15% | +15% |
With a Ryzen 5 7600 or slower, most of the RTX 5080’s lead is lost at 1440p because the processor cannot keep up: before paying for the faster card, check the processors that suit the RTX 5080.
Each card’s gaming figure comes from the reference data the Bottleneck app uses to judge the hardware it measures; the processors are compared with the same model as the bottleneck calculator, where frame rate is set by whichever part is slower. The figures are for a typical game at high settings and rounded to 5%: individual games, ray tracing and upscaling move them, and price and power draw are not part of it.
Before buying a faster graphics card, make sure your PC gets what it should from the one it has: a setting left wrong can cost as many frames as the upgrade would add. Bottleneck checks the usual reasons a PC falls short of its parts, free: memory below its rated speed or in single channel, Resizable BAR and GPU scheduling left off, a monitor held at 60 Hz, heat. Then, while you play, it records which part set the pace in every frame.
