I have an AMD 6490m gpu. On the specification it says that its frequency is 700 mhz, but when I obtain the max clock frequency parameter from the opencl api I get 150 mhz. Does anyone know what is the problem?
my platform:
Apple Apple OpenCL 1.2 (Sep 20 2014 22:01:02), FULL_PROFILE
CL_DEVICE_NAME = ATI Radeon HD 6490M
CL_DEVICE_VENDOR = AMD

CL_DEVICE_MAX_COMPUTE_UNITS = 2
CL_DEVICE_MAX_WORK_ITEM_DIMENSIONS = 3
CL_DEVICE_MAX_WORK_ITEM_SIZES = 256 / 256 / 256
CL_DEVICE_MAX_WORK_GROUP_SIZE = 256
CL_DEVICE_MAX_CLOCK_FREQUENCY = 150 MHz
CL_DEVICE_GLOBAL_MEM_SIZE = 256 MB
CL_DEVICE_ERROR_CORRECTION_SUPPORT = NO
CL_DEVICE_LOCAL_MEM_SIZE = 32 kB
