Hi,
I have the same issue. I'm using the 64 bit linux driver version 12.4 and gDEbugger 6.2.438.0.
I create a Image2D with 1920x1080 with cl::ImageFormat(CL_RGBA,CL_FLOAT). This should take 1920x1080x4x4=33'177'600 bytes. However, gDEbugger tells me that is uses 4,050 KB. This is what the debugger tells me "Image 17, 4,050 KB, 2D, 1920x1080, OS_TEXEL_FORMAT_RGBA, OS_FLOAT, 1"
So why this enormous difference. Does the Image2D map to some kind to texture which is compressed?
Thanks
Michael
