Sapphire Radeon RX 5700 XT Pulse Review
Clock Speeds & Power Limit »Overclocking
Manual overclocking has gotten a little bit more stable than on AMD's first drivers. We still had to raise the power limit to its maximum to see any meaningful overclocking.
With manual overclocking, maximum overclock of our sample is 1900 MHz on the memory (9% overclock) and 2050 MHz on the GPU, which increases average GPU clock from 1915 MHz to 2001 MHz (5% overclock). Memory overclocking is limited now by the length of the slider in Wattman, which doesn't go higher than 950 MHz.
| Maximum Overclock Comparison | |||
|---|---|---|---|
| Avg. GPU Clock | Max. Memory Clock | Performance | |
| AMD RX 5700 | 1726 MHz | 1860 MHz | 101.5 FPS |
| AMD RX 5700 XT | 2015 MHz | 1840 MHz | 118.1 FPS |
| ASUS RX 5700 XT STRIX | 2031 MHz | 1900 MHz | 118.3 FPS |
| MSI RX 5700 XT Evoke | 2050 MHz | 1900 MHz | 119.6 FPS |
| PowerColor RX 5700 XT Red Devil | 2000 MHz | 1900 MHz | 117.0 FPS |
| Sapphire RX 5700 XT Pulse | 2001 MHz | 1900 MHz | 117.8 FPS |
Overclocked Performance
Using these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 3.6%.
