Totally understand that Intel's manufacturing problems are a really important factor here, but GP was talking about their lack of IPC gains, which is exactly the kind of thing I would imagine they hired Jim to solve.
- eloff 6y agoI think the confusion is because the chip design is tied to the manufacturing process. Intel likely has IPC gains in their new architecture for 10nm, but they can't manufacture that yet, and they can't just build it on 14nm instead without significant work to port the design to the new process node.
- localhost 6y agoThanks for clarifying things; as a software guy this is all in the realm of "magic" to me :) Do you have any pointers to layperson things that I can read about microarchitecture design improvements and process nodes?
- ksec 6y agoFor beginners, just go through the list of article on Anandtech would be good enough for most. From IPC, uArch to Fab, that would take at least a few weekends to get a meaningful understanding. After that Wikichip is a more intermediate+ level site. I just want to add additional information to your parent, it is not quite Intel cant manufacture it yet, they have it on mobile, called Ice Lake, and Tiger Lake coming later this year. So that is 2 generation ahead of its desktop counterpart.
- StillBored 6y agoWell, this has been the discussion about porting it to 14++, but presumably they need a higher density to cram a bunch of extra transistors into the design. Hindsight at this point, but a big rich company like intel, should have had a fallback plan to port it to 7nm (or whatever) at TSMC a couple years ago to keep the pipeline full. It would have been a huge black eye, but at least they would have been moving forward while they straighten out their own manufacturing story.
