TechPowerUp has updated GPU-Z to version 0.6.4 and with it brought some interesting changes. According to TechPowerUp, "version 0.6.4 adds/refines support for several upcoming NVIDIA GPUs, such as GeForce GTX 660 Ti, GeForce GTX 660, GeForce GTX/S 650, GeForce 610, and GeForce GTX 680M; Intel GMA 3600 (ROP count); AMD "Trinity" APUs (clock reading accuracy) and AMD FirePro 2270."

Usually software like this is updated shortly before the release of a new product, such as the NVIDIA GTX 660 Ti, rumored to be launching soon. Support for the NVIDIA 650 also shows that the September launch period is likely an accurate rumor. TechPowerUp also instituted several other changes in the newest version:

• Changed sort order of devices to put devices with connected monitor first
• Fixed memory size reading for NVIDIA cards with 4 GB or more
• Fixed AMD Trinity Fusion clock readings
