NVIDIA GeForce GPUs function hotspot temperature measurement akin to AMD Radeon ones, in keeping with an investigative report by Igor’s Lab. A beta model of HWInfo already helps hotspot measurement. As its title suggests, the hotspot is the most well liked spot on the GPU, measured from a community of thermal sensors throughout the GPU die, in contrast to typical “GPU Temperature” sensors, which reads off a single bodily location of the GPU die. AMD refers to this static sensor as “Edge temperature.” In some instances, the reported temperature of this sensor might differ from the hotspot by as a lot as 20°C, which underscores the significance of hotspot. The sensor with the very best temperature measurement turns into the hotspot.
GPU producers hardly ever disclose the bodily areas of on-die thermal sensors, however throughout the AMD Radeon VII, we obtained a uncommon glimpse at this, in an organization slide, with the sensors being situated close to parts that may get the most well liked, such because the compute models (pictured beneath). Igor’s Lab put out measurements of the deviation between the hotspot and “GPU temperature” sensors on a GeForce RTX 3090 Founders Edition card. There’s a a lot narrower deviation between the 2 (between 11-14°C), and than the one between hotspot and Edge temperature on an MSI Radeon RX 6800 XT Gaming X Trio (which posts a 12-20°C distinction).
