Good thing the Radeon RX 5700 cards work at 110C



AMD has published a blog detailing how the GPU and thermal management systems work on new graphics cards from the Radeon RX 5700 series, just as custom navigation cards do.

There is some mystery to how everything works, but Mithun Chandrasahar – Senior Product Manager, Radeon Technologies Group at AMD has published a long and detailed blog on AMD's official website.

In the post, Chandrasekhar writes that with AMD, using its extended network of thermal sensors distributed in the Navi GPU of Radeon RX 5700 series cards "intelligently monitor and adjust performance in response to in-depth GPU activity in real time".

He continue: "Paired with this array of sensors is the ability to identify the "hot spot" in the GPU. Instead of setting a conservative, "worst-case" throttle temperature for the entire matrix, Radeon RX 5700 Series GPUs will continue to opportunistically and aggressively ramp the clock until one of the many sensors available hits the hot-spot or "temperature" connecting "at 110 degrees Celsius. Operation at temperatures up to 110C Junction Temperature during typical game usage is also expected within specification. This enables the Radeon RX 5700 Series GPUs to offer much higher performance and out-of-the-box watches while maintaining acoustic and reliable goals".

Now this is shocking to those who have just seen the huge 110C number, but he said it was "expected and within specification". My testing with the reference Radeon RX 5700 XT (my review here) saw it reach 84C and higher while SAPPHIRE's new Radeon RX 5700 XT PULSE OC (my review here) works much cooler at temperatures between 68-72C depending on the load.

I have another user review of the Radeon RX 5700 XT tomorrow, and I need to look at some more thermal tests. With this review out of the way, we can take a closer look at the thermal performance of the maps and even test the custom Arctic Cooling solution I have along the way.

But whatever you shake, 110C is pretty crazy height that we are at the moment … and it's at 7nm node.

The post itself is quite detailed and worth reading, so See here,
