C-60 APU and Radeon HD6920

(1/7) > >>

Raistmer:
With preinstalled OS (Win7 x64 home premium) there is no OpenCL support on GPU (but Direct Copmute 5.0 supported).
I tried to find update on AMD site but highest APU listed there is C-50. So I download "11.12 mobility drivers" for Win7 x64.
Will see if this driver can be used for my hardware config and will it provide OpenCL support on this netbook or not.

Raistmer:
My hopes are fulfilled, this APU-based netbook can do OpenCL indeed!

From the other side it can't do SSSE3 (at least, Intel's flavour one).

Raistmer:
GPU clocks look strange:

Raistmer:
when GPU idle it rises to 400MHz but with busy GPU it drops to 275MHz



Maybe power usage restriction applies?
it's netbook after all...

Mike:
GPU temperature seems a little bit high to me.
