Shomoha Posted January 24, 2010 Share Posted January 24, 2010 I saw in Apple Site that in new 27' Imac there is two Video Graphics and video support 21.5-inch models, one of the following: NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory3 ATI Radeon HD 4670 graphics processor with 256MB of GDDR3 memory 27-inch model with dual-core processor, one of the following: ATI Radeon HD 4670 graphics processor with 256MB of GDDR3 memory ATI Radeon HD 4850 graphics processor with 512MB of GDDR3 memory 27-inch model with quad-core processor: ATI Radeon HD 4850 graphics processor with 512MB of GDDR3 memory But I read in netkas.org site that Ati support of Open CL/GL is a poor Suport: " Radeond OpenCL support is very poor, only few of many apple’s opencl demo run on it, this opencl banchmark will result in errors in graphics driver and graphics will stop working untill reboot. the error was due to benchmark used too much local memory(driver should handle that and not just stop gpu), and results is that 4870 is 1.5 times faster than c2q 3ghz, but 15 times slower than gtx285 " how it is possible?
