NVIDIA GPUs Have Hotspot Temperature Sensors Like AMD
NVIDIA GeForce GPUs function hotspot temperature measurement akin to AMD Radeon types, in accordance to an investigative report by Igor’s Lab. A beta variation of HWInfo presently supports hotspot measurement. As its title indicates, the hotspot is the hottest place on the GPU, calculated from a community of thermal sensors throughout the GPU die, as opposed to traditional “GPU Temperature” sensors, which reads off a solitary physical place of the GPU die. AMD refers to this static sensor as “Edge temperature.” In some conditions, the noted temperature of this sensor could vary from the hotspot by as substantially as 20°C, which underscores the worth of hotspot. The sensor with the highest temperature measurement results in being the hotspot.
GPU makers not often disclose the actual physical destinations of on-die thermal sensors, but through the AMD Radeon VII, we received a rare glimpse at this, in a organization slide, with the sensors remaining located near elements that can get the best, this kind of as the compute units (pictured below). Igor’s Lab place out measurements of the deviation concerning the hotspot and “GPU temperature” sensors on a GeForce RTX 3090 Founders Edition card. You will find a significantly narrower deviation among the two (between eleven-14°C), and than the just one amongst hotspot and Edge temperature on an MSI Radeon RX 6800 XT Gaming X Trio (which posts a 12-20°C difference).
