AMD Trinity specs, fp64

I was wondering, what extensions are supported by the GPU in AMD Trinity APU, which has been reviewed today. Does it support cl_khr_fp64 and if so, what is the ratio of SP to DP performance?  And does it support the zero-copy extensions under Windows and Linux?

Sorry that's not correct.  Trinity has 1:16 rate doubles compared to single precision.

Yeah I read that too. I am the user who posted the question there

Now, the question is, what is the DP:SP ratio? 1:4 as in Cayman or lower?

Trinity is using the Cayman core, so 1:4.

[Edit] Sorry I got this one wrong, its a derived cayman core, with 1:16 ratio as JeffG pointed out below.

Ok I see. Thanks for the clarification. Somewhat disappointment, but still good for testing and dev purposes I suppose.
