The Radeon RX 7900 XT, which is currently ranked at 315 watts, regularly attracts 340 to 350 watts under lots, with a number of spikes as much as 360 watts as well as one spike as high as 389 watts observed throughout a solitary 3DMark Rate Method run. Regarding the Radeon RX 7900 XTX, which is ranked at 355 watts, it regularly gets to the 370 to 390 watt variety, increasing as high as 406 watts in this examination.
I did additionally attempt PCAT logging with the Radeon RX 7900 XTX throughout a video game engine examination, as well as throughout a run of City Exodus Improved Version at 3440 × 1440/ Extreme I videotaped spikes as high as 421 watts. That is 100 watts greater than the most significant spike we videotaped from our RTX 4080 FE, though I will certainly upgrade with PCAT going to the NVIDIA side also.
Prior to jumping to any kind of verdicts concerning bad deed below with an NVIDIA power screening tool, please recognize that we could not rely upon our typical GPU-Z logging. Throughout our screening leading up to this testimonial, GPU-Z was not reporting power draw with these brand-new Radeon cards. The PCAT equipment was a fantastic option, as it just rests in between the PCI Express power as well as port power as well as presents the present draw from each.
Ultimately, a fast note on observed thermals with these recommendation cards. I do not have Players Nexus-style thermal probes or a few other equipment option, so I’ll need to rely on the temperatures reported by the GPUs. Throughout the bent City Exodus benchmark runs I made use of to tape-record GPU regularities, the greatest GPU core temperature was reported as just 67 C, with the GPU location videotaped as 79 C (in a really great 17– 18 C space). These numbers went down to 60 C core, 71 C location with the recommendation 7900 XT in the very same examination.
There are some issues with this method to check thermals, not the least of which is the 90-second period of the criteria (though it did run 10 times in a row). I just supply this info below since I have the information, however thermals will certainly need to be more checked out in a longer period examination.
