since its released suppose someone at AMD can answer this:
I have questions regarding OpenCL in a 4850 in Snow Leopard..
1. Has it doubles support? cl_khr_double
2. Has OpenGL interop? cl_apple_gl_sharing..
3. Return kernel binaries (in AMD IL)
Assuming some are negative are they going to be supported later via SO updates.. or will stay as of now..
Also I have seen some info that return:
Name: Radeon HD 4870
Device Version: OpenCL 1.0
Driver Version: 1.0
Compute Units: 4
Work Group Size: 1024
Clock: 1000 MHz
Global Memory: 128 MB
Local Memory: 16384 KB
Cache Size: 0 KB
Cache Line Size: 128 Bytes
Why Compute Units: 4 are not 800 shaders or 160 vector units..
why no extensions?..
atomic are not supposedly supported on hardware (cl_khr_global_int32_base_atomics,cl_khr_global_int32_extendde_atomics)
Also what about
are memory not byte addresable?
