Apple has updated its iMac line with new Intel Sandy Bridge CPUs and latest AMD’s GPUs: Radeon HD 6750M, HD 6770M and HD 6970M.
Here are the features of these GPUs:
- HD 6770M and HD 6750M: 480 stream processors, core @ 500-725MHz and 512MB of GDDR5 memory @ 800-900MHz.
- HD 6970M: 960 stream processors, core @ 580-680MHz and 512MB of GDDR5 memory @ 900MHz.
All these graphics cards support OpenGL 4.1 and OpenCL 1.1. But if I’m not wrong, OpenGL 4.x is not supported by Mac OS X (Snow Leopard). Only OpenGL 2 and OpenGL 3 APIs are available for graphics developers.
All new iMac comes with 4GB of system memory, a Core i5 CPU and 500GB/1TB hard drive:
