Benchmark values and test results …
The ASRock Phantom Gaming X Radeon RX 590 8G OC has been tested on the following system:
ASRock Fatal1ty AB350 Gaming K4
AMD Ryzen 7 1800X
Crucial 4GB DDR4-2400
Cooler Master Testbench v1.0
Windows 10 Professional 64 Bit
Unigine Heaven Benchmark 1080p Ultra Settings
Unigine Super Position Benchmark – 1080p Extreme Setting
3DMark Firestrike Extreme
After this first run in the default setting we also look in GPU-Z at the maximum temperature, which was measured during the benchmarks: 70°C are a good value for the fact that in Smart mode the RX 590 is audible but not loud.
Now we have with the values of the default mode reference values, with which we can compare the other modes.
The OC mode can increase the performance, but the gain is limited in view of only 31 MHz more GPU clock. Let’s see how the silent mode performs …
Overall, the assumption that the 3 modes are pretty close together is confirmed.
AMD RX 590 graphics card overclocking …
OC versions of graphics cards are always operated by the manufacturer with clock rates that are higher than the standard clock rates that AMD or nVidia provide, but often there is still a little more room for improvement so that the ambitious overclockers can still fine tune. In the first step, we only raised the RAM clock and were able to move the controller a maximum of 2250 MHz to the right, without having to increase the voltage. The GPU ran with the ASRock OC clock of 1591 MHz and 20% increased power limit. We are curious how the increase in memory bandwidth will affect performance.
Where the performance gain through higher GPU clock was previously behaving rather behaved, the increase can be seen absolutely by the increased RAM clock. This seems to be the true bottleneck of the RX 590.
But now it’s time to pull all the controls to the limit and test where the card’s maximum is :ocinside: We finally reach a stable 1650 MHz GPU or 2250 MHz RAM clock and increase the power limit by 50%.
All in all, we were able to get a bit more performance by further overclocking, but the higher RAM clock made the biggest difference, whereas the approximately 60 MHz more GPU clock compared to the OC clock of 1591 MHz with more voltage and higher power limit were bought at a high price. For the 24/7 OC operation we would therefore tend to 1600/2250 MHz GPU/RAM clock, so that no voltage increase should be necessary.
