Anand Lal Shimpi in Macworld extolls the future of CPUs and GPUs and what it means for future Apple products and Intel’s Sandy Bridge technology:
The second-generation of its Core i-series CPUs (code-named Sandy Bridge) will come out in January 2011.
What about graphics?
Sandy Bridge will have on-die graphics, but that hardware won’t support OpenCL. While I believe Sandy Bridge’s graphics will be fast enough for the majority of OS X users, I don’t think Apple will want to stop shipping OpenCL-capable GPUs in its systems.
When will they show up?
I’d expect to see Sandy Bridge chips appear in MacBooks, MacBook Pros, and iMacs sometime in the first or second quarter of 2011; I’d expect the Mac Pro to get Sandy Bridge sometime in 2011’s third or fourth quarter.
I have an aging iMac that’s ready for eBay and a much faster replacement.
