I've seen many people post that they want to see an ATI GPU. I was wondering if there was a particular reason for this. I don't know much about Nvidia's chips, do they not offer any with comparable performance and efficency? If it's an ATI, I hope it's the ATI Mobility 5850 NOT the 5830. Why, you ask? Because the main bottleneck for the GPU will be the memory. There are two ways you can get rid of that bottleneck. You can either use a GPU with a 256-bit bus, or you can use a GPU that uses GDDR5 memory instead of the far slower GDDR3 memory. The 5830 offers neither, and is thus heavily bottlenecked by the memory. Both the 5850 and 5870 use GDDR5 memory and thus hold their own against even higher end desktop GPUs. As far as I'm concerned, as long as it's a current gen (Direct X 11) GPU with either 256-bit or GRRD5 ram, I would be satisfied regardless of who makes it. I wasn't aware that the Nvidia 250GTS came with GDDR5 but if it indeed does, I would be perfectly satisfied witht that chip as well. So which do you hope to see? Is there a particular reason why you prefer ATI or Nvidia or do you not care as long as its either GDDR5 or 256-bit? P.S: It's not technically GPU related but I'm also really hoping to see the improved GPU taken advantage of with a 1920×1080 Resolution screen on the High End 15" MBP, along with either a Display Port With Audio Output Support or a HDMI port, a higher resolution iSight camera and a blu ray drive either now or by October.
