In games, the Core i5-12400 is about 15% faster than the Ryzen 5 5600 when the graphics card does not hold it back. Both have 12 threads.
A faster processor only shows in frame rates when the graphics card can draw the extra frames. How much more the Core i5-12400 delivers than the Ryzen 5 5600, with common graphics cards:
| Graphics card | 1080p | 1440p | 4K |
|---|---|---|---|
| RTX 3060 | No gain | No gain | No gain |
| RTX 4060 | No gain | No gain | No gain |
| RTX 5060 Ti | +10% | No gain | No gain |
| RTX 5070 | +15% | No gain | No gain |
| Radeon RX 9070 XT | +15% | +15% | No gain |
| RTX 5080 | +15% | +15% | No gain |
| RTX 5090 | +15% | +15% | +10% |
| Any graphics card fast enough | +15% | +15% | +15% |
At 1440p the Core i5-12400’s lead shows with a Radeon RX 9070 XT or faster; with a slower card, the graphics card sets the pace and the slower processor does as well. Graphics cards that suit the Ryzen 5 5600.
Each processor’s figure for games comes from the reference data the Bottleneck app uses to judge the hardware it measures: mostly single-core speed, with a share of multi-core speed up to what an eight-core chip offers, and adjustments for AMD’s X3D cache and Intel’s Core Ultra memory latency that published game tests show. The graphics cards are compared with the same model as the bottleneck calculator. It is about games only, for a typical game at high settings, rounded to 5%: work that uses every core, price and power draw are not part of it.
Before buying a faster processor, make sure your PC gets what it should from the one it has: memory left at a slow default speed can cost as much 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.
