There's an app called GPU Caps viewer which will show the capabilities of all the OpenCL devices available in your system.
asking about my gpu information using opencl
Question
can any one help me how can find this information about my platform i can find it using getdeviceinfo . there are any method for that or complete code to fetch all this info

OTHER TIPS
Take at look at the Intel OpenCL SDK
There's an app they provide called "Basic Capabilities" that lists most of what you're looking for. Each app even comes with a PDF users guide. Near the back the users guide has a section called "Controlling the Sample" which lists command-line options for the app.
One of the command line options is <PLATFORM>
. The apps default to looking for "Intel" hardware but I've specified the platform as "NVidia" and things worked for me.
