I wanted to run Folding@Home on my laptop. I downloaded version 6.41 which supports GPGPU for ATI with the r_700 switch. It seemd too work slow so I took a look with GPU-Z and I was puzzled.

ATI Mobility Radeon HD 4500 - Support OpenCL or not?

I thought it does but according to GPU-Z it doesn't. Can anyone clear things for me?

It does support OpenCL. I have same GPU in my HP laptop.

This is how to get OpenCL support:

  1. Download AMD app SDK short for AMD Accelerated Parallel Processing (APP) SDK (formerly ATI Stream) you get it from here
  2. Supported drivers are available here
  3. Download and install your driver using the latest Catalyst driver installer for your GPU device

After that is done your device should support OpenCL. To check if it worked, use GPU-Z or GPU caps viewer.

AFAIK, AMD/ATi begun supporting OpenCL starting with their DirectX 11 cards. Your card is DirectX 10.

Here is the list of supported GPUs:

I looked at your link. What does it mean "Devices with Beta Level Support"? Does it support or not? – Randall Flagg Feb 19 '11 at 18:35
Probably that it does not support by default with default drivers. – vartec Feb 20 '11 at 12:07
