Intel gave up on desktops. They started the death spiral. Laptops won't get faster, just GPU bumps.
Look at numbers for Haswell vs anything since. It's not much. Microsoft's windows 10 move further hurt them because people can sit on PCs longer. Microsoft had to save themselves.
Intel needs to blow out performance on PCs to get upgrades started again and for that to matter, we need a new killer app for PCs that require real CPU power. Something that can't be done on a tablet right now. Something that isn't easily offloaded onto cloud computing.
I'm just hoping AMD doesn't give up on gamers or desktops. I need FX or core i7 CPUs for what I do and I realize it's not common, but there are CAD users, programmers, engineers, etc that need CPU performance. They killed workstations because of PC speeding up and now they want to kill PCs... what are we supposed to use?
Yeah, they can't sell to grandma anymore and I'm going to have to pay a lot again like I did when I first started using computers, but I still need a fast PC and a laptop CPU won't cut it.
And for the record, I also have multiple PCs. My wife is also a programmer and a gamer. She has a 6 core intel haswell-e desktop and used to buy Mac Pros . I've got a core i7 4770 with 32GB of RAM, 3 SSDs and 2 hard drives. I've also got lowend servers running for building software and running websites. I know I'm not the norm, but there are segments like me out there.
