Not long ago, Intel had scheduled a number of CPUs for retirement; now we have another list. This time, there are two Ivy Bridge CPUs along with seven Bay Trail units.
To start off, the Core i7-3840QM along with the Core i7-3740QM are being retired. They can still be ordered until August 22 and will ship until February 6, 2015.
The Celeron 2810, N805, J1850, and J1750 will be available until the same dates as the above Ivy Bridge units.
Lastly, the Pentium N3510, Pentium J2850, and Celeron N2910 will be available for order until February 21, and will ship until April 25, 2014.
That in itself wouldn't be that big a problem. I mean you could do the thread ordering in software, swap the RAM out to take care of GDDR's large latencies and probably still come out with more power than a CPU at GPU specific tasks. The real issue, before you get to threading, is instruction set. How the hell with a GPU actually process an OS and the wealth and diversity of data that comes with it. Terribly.
And that's symptomatic of the relationship between CPU and GPU. As things get more specialised, they get more powerful at that task at the expense of all others. A GPU is basically a video ASIC. A CPU is basically a computing Jack of all trades.
