no double support for Radeon HD 7500/7600 Series?

Hi All,

 

I've got a toshiba Satellite-S875D which has an A10 processor and a HD 7610M second video card.

 

The 7610m seems to get treated as a 7500/7600 in linux:

 

jape@jape-Satellite-S875D:~$ aticonfig --list-adapters

* 0. 00:01.0 AMD Radeon HD 7660G

  1. 01:00.0 AMD Radeon HD 7500/7600 Series

 

What I'm wondering about is the lack of any fp64 extension for the 7610m:

  Extensions:                                cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_3d_image_writes cl_khr_byte_addressable_store cl_khr_gl_sharing cl_ext_atomic_counters_32 cl_amd_device_attribute_query cl_amd_vec3 cl_amd_printf cl_amd_media_ops cl_amd_popcnt

 

 

in windows the 7660g reports cl_amd_fp64 as an extension.

 

Is this expected?  Does the 7610M not have any support for doubles in opencl?

 

regards,

 

jp
