Hi Martin,  
  
unfortunately we can’t give out any specific information at the moment.  
You will have to wait until the first devices ship with OpenCL support.

Thanks! There is a factsheet ( [https://www.imgtec.com/factsheets/powervr/POWERVR\_SGX\_Series5\_IP\_Core\_Family.pdf](https://www.imgtec.com/factsheets/powervr/POWERVR_SGX_Series5_IP_Core_Family.pdf) ) which seems to claim that all SGX Series 5 GPUs support OpenCL 1.1. Is this the case? Then it should be only a question of the drivers whether the GPU's support for OpenCL is exposed, right?

Hi Martin,  
  
please have a look at Gordon’s post:

Not sure if you guys have seen this:  
  
[http://www.hotchips.org/archives/hc21/1\_sun/HC21.23.2.OpenCLTutorial-Epub/HC21.23.270.Pulli-OpenCL-in-Handheld-Devices.pdf](http://www.hotchips.org/archives/hc21/1_sun/HC21.23.2.OpenCLTutorial-Epub/HC21.23.270.Pulli-OpenCL-in-Handheld-Devices.pdf)  
  
This is a presentation that a Nokia engineer gave at the Hot Chips 21 symposium. It show a performance comparison of an image processing kernel running on the GPU (PowerVR SGX530), CPU (Arm Cortex A8), and a combination of both on an OMAP 3430.  
  
It also mentions the potential of workload management on future chips:  
"OpenCL can allocate workload on multiple processors...for example in OMAP 4430 there are 2 X Arm Cortex A9, ISP, GPU, DSP"  
  
Now, whether or not OpenCL drivers will be available for ALL of the OMAP 4 computational resources is another question...but clearly Nokia got a driver for the CPU and GPU from SOMEONE to try this experiment. And this is from August 23rd, 2009.

Of course drivers exists… for device engineers only. Perhaps Nokia was given permission to try an in-house driver, or maybe Nokia whipped up something quick to try. The API is probably still in beta and not ready for public release. Who knows.
