ASUS Radeon HD 7850 DirectCU

For starting off with some Linux thermal results for this ASUS "DirectCU" graphics cards are some numbers from the Phoronix Test Suite when setting the MONITOR=cpu.temp,gpu.temp,gpu.usage environment variable prior to running a few OpenGL Linux benchmarks to see how the graphics card was running.

Unfortunately since the used Catalyst driver was reporting "unsupported hardware" when testing the other AMD graphics cards, the amdconfig utility doesn't work in these "unsupported" cases. Without the working utility, the GPU load and temperature can't be read via the OverDrive information with amdconfig. As a result, the only AMD numbers that could be shared were for the ASUS Radeon HD 7850 itself and not any of the other AMD GPUs on Ubuntu.

These results are when running Unigine Heaven followed by Xonotic.

The ASUS Radeon HD 7850 DirectCU graphics card started off at a cool 32°C but was averaging at 60°C when enduring the heavy load of these Linux OpenGL demos. The peak temperature for the DirectCU graphics card was 64°C. In the time between test runs, the GPU core temperature was quick to receed.

Unigine Heaven did a particularly good job with keeping the HD 7850 Pitcairn GPU under near-constant load.
