If that's true, then yeah, even | Apple might go back eventually. Just for the fabs, of course. | Not use Intel CPUs. I believe this is what Gelsinger meant when | he said he would like to win Apple back | PedroBatista wrote: | I really hope Gelsinger used that as an expression, not a | real goal or strategy. | | Apple using an Apple chip, given the recent past and | circumstances is both a technical and a political move. Going | back to Intel ( or AMD ) would be an humiliation and Apple's | track-record dealing with inferior products has been | basically ignore the problems and put their spin machine to | use. | | I hope Intel gets better but I also hope they don't get much | better than anyone else because the last time that happened | their arrogance and anti-competitive moves were so bad even | their most "loyal" corporate customers HATED them with a | passion. | Figs wrote: | Related discussion from a few days ago: | https://news.ycombinator.com/item?id=37315802 | nvm0n2 wrote: | I wonder how good this sort of chip would be for (parallel | capable) compilers.

I feel like apple is beating intel on chips. | RandomBK wrote: | This isn't a production unit, but a research project to play | with silicon photonics. | Almondsetat wrote: | TSMC is beating Intel on chips* | littlestymaar wrote: | Yeah, also "7nm" and "3nm" aren't actually measuring the same | thing (IIRC Intel 7nm is equivalent to TSMC 5nm) | ftxbro wrote: | well if the measurements are only marketing words now, then | intel should just measure something else and say that they | have 2nm | peyton wrote: | Yeah kinda, they basically did a rebrand recently. | avianlyric wrote: | That's exactly what Intel are planning to do | | https://arstechnica.com/gadgets/2021/07/intels-foundry- | roadm... | [deleted] | bryanlarsen wrote: | Intel 7nm and TSMC 3nm are roughly equivalent, they both have a | transistor density of 200 - 250 MTr/mm2. | tux3 wrote: | No, there is no Intel 7nm anymore, it was renamed to Intel 4. | But there is instead an Intel 7, which is the previous Intel | 10nm ESF. | | This marks the point where they changed their naming scheme, | so that Intel 7 is roughly comparable to TSMC N7 (not to TSMC | N3, which would be Intel 4). | | And this chip is on TSMC 7nm per the article, not Intel 7 or | Intel 4 (the former "7nm"). | meepmorp wrote: | Apple only had 90% of TSMC's 3nm capacity this year, with Intel | contracted for the other 10.
