AMD Wanting Into RX 7900 Collection Temperature Points

Posted on


AMD’s reference designs for its flagship RDNA 3 GPUs garnered early reward for being comparatively glossy and for sensibly sticking with 2x 8-pin energy connectors. However these Made By AMD (MBA) designs could endure from thermal points — at the very least, that is what German tech web site HardwareLuxx is investigating, following a wake of reviews that Radeon RX 7900 XT(X) playing cards are affected by high-temperature sizzling spots, loud followers, and thermal throttling.

An AMD spokesperson confirmed that they are investigating the problems in a press release to HardwareLuxx: “Our GPU crew is at present wanting into the issue.”

Utilizing knowledge from a handful of evaluations in addition to customers from its boards, HardwareLuxx has proven that customized Radeon 7900 XT(X) designs seem to have a most delta of 20 levels Celsius between the GPU’s common temperature and high-temperature sizzling spots. Which means that even when the GPU’s temperature hits 80 C, the new spot stays <100 C and the graphics card won’t throttle.

Nonetheless, MBA reference designs have been noticed with GPU/sizzling spot temperature deltas as excessive as 53C (a 56C GPU with a 109C sizzling spot), and this appears to be a considerably constant situation. Which means that a GPU with a modest common temperature of round 60C might begin throttling if the hotspot reaches 110C.

If MBA designs are affected by this huge GPU-to-hot-spot delta and third-party designs aren’t, it looks like the apparent perpetrator could be AMD’s reference cooling designs. HardwareLuxx did not bounce to this conclusion, as a substitute opting to debate direct die cooling of the Navi 31 GPU being troublesome as a result of chiplet design presenting an uneven floor to the cooler. Particularly, editor Andreas Schilling stated “we suspect that an uneven contact strain is liable for the excessive temperature variations.”

Taking a look at a naked PCB, the publication says the central GCD and 6 MCDs are stuffed and look degree, so there could possibly be one thing else inflicting uneven contact points (such because the GPU body). In our testing, the reference-model Radeon RX 7900 XT(X) playing cards did not appear significantly noisy, nor did they throttle or have any temperature points (they reached a good most of 70C). Nonetheless, it is actually potential extra strenuous workloads might end in larger temperatures — FurMark for instance confirmed somewhat low GPU clocks within the 1650–1700 MHz vary.

Regardless of the situation is, it appears like AMD is wanting into it — hopefully they’re going to discover a resolution, and possibly they’re going to additionally check out the noisy followers and different points Radeon RX 7900 XT(X) homeowners have been going through.
