Afterburner for amd cards9/10/2023 Consequently, MSI Afterburner doesn't even offer the option to lower the voltage. Nvidia simply has its mechanism optimally balanced, so there's practically no room for improvement. It's not something to complain about, per se. In turn, this results in a massive performance hit. Since GPU Boost is a very fragile system, every little drop has a negative impact on clock rate. Lowering the GPU's voltage just isn't in the cards because it's achieved by decreasing the internal power target. If you're aggravated and want to see the same gains from Nvidia's GPU, get ready for disappointment. The Sapphire Radeon R9 Fury X Nitro's power consumption plummets from 279W all the way down to a much more moderate 213W. Of course, that only works when your GPU is willing to cooperate at such a low voltage. When we compare the different voltage targets to MSI's GTX 980 Gaming 4G, for instance, in a Metro: Last Light loop running at 4K, then the value of our endeavor is plain to see. These graphics cards were almost exclusively bought right after the launch, and could have been unlocked. However, older cards, which we tried with the help of forum members, couldn't achieve the same low numbers. Values from -48mV to -72mV should be possible for any newer GPU. Our review sample managed -96mV stably enough, other than an occasional drop under extreme load. However, even with these, your mileage will vary. The newer ones are a lot easier to undervolt. These GPUs were only made into Furies by a somewhat adventurous unlocking process. All of a graphics card's features need to be used for a prolonged period of time to determine if the configuration is stable.Cards made during AMD's early production cycle are particularly prone to display problems after undervolting. What's more, errors don't always become apparent immediately. This means that the lowest number at which a processor still functions without errors can be different from one to the next.
