Apple just unveiled new lineup of iMac with Radeon 4670 & 4850 (except the entry model with GeForce 9400M IGP).
I don’t understand this move, because Radeon 4xxx are just under-performers on OpenCL, except on some benchmarks that just do mul-add (MADD) or bandwidth tests. Radeon 5xxx may have been better choice, but they are not available, but it seems that nVidia and Apple divorced after 1 good year of successfull collaboration…
I just wonder why Apple choose ATI Radeons, except for the GPU price?
Underperformers on OpenCL, a big novelty on Snow Leopard, and unsable to play games correctly at native screen resolution (Radeon 4670 on 1920×1080 and Radeon 4850 on 2560×1440). Clearly it’s a dumb move, nobody will be satisfied by these choices, nor gamer nor OpenCL developer or software user!
