Nouveau Driver Power Management vs The NVIDIA Blob

Filed under
Hardware
Software

Following last week's completion of the Radeon driver power management tests against the AMD Catalyst driver, now it is time to turn the tables on NVIDIA. In this article are some power consumption and thermal tests when comparing the latest open-source "Nouveau" driver code against NVIDIA's closed-source proprietary driver.

Testing went nearly the same as last week's Radeon driver power management test. The Watts Up Pro USB power meter was monitoring the system's power consumption, which was being automatically logged by the Phoronix Test Suite. Also monitored at the same time by the Phoronix Test Suite was the CPU usage and GPU temperature.

The NVIDIA GeForce graphics cards that were tested in this review included the 8500GT, 8600GTS, 9500GT, and 9800GT.
