Semiaccurate claims that this is entirely Intel marketing fluff, and that in reality Intel can't get 10nm yield up to useful levels, now or ever.
(that's a tl;dr for https://www.semiaccurate.com/2019/04/25/leaked-roadmap-shows-intels-10nm-woes/ https://www.semiaccurate.com/2019/04/25/leaked-roadmap-shows... )
- liuliu 8y agoMy understanding is that Intel is doing OK with smaller die size 10nm (Cannon Lake-U / Ice Lake-U) for Ultrabooks. But for bigger dies such as HEDT or server CPUs, the Ice Lake SP is still pretty much in the air with Intel's vague timeline of "sooner than expected end of 2020" claim.
- happycube 8y agoCannon Lake-U is definitely not OK, the GPU is disabled in all shipping parts, and aside from AVX-512 really isn't much better than the equivalent 14nm part. Ice Lake-U sounds better on paper - at the very least it's a 4C die.
- TazeTSchnitzel 8y agoIsn't that “Ultrabook” part the one with the broken GPU that's shipping only in an obscure variant of a cheap Chinese education-only laptop?
- shorts_theory 8y agoYes, that's the one. Anandtech did a pretty good analysis of Cannonlake here: https://www.anandtech.com/show/13405/intel-10nm-cannon-lake-and-core-i3-8121u-deep-dive-review/ https://www.anandtech.com/show/13405/intel-10nm-cannon-lake-...
- AmVess 8y agoCanon Lake is the opposite of OK. Its turbo modes are much lower than the previous gen, and it clocks itself lower by 600 MHz under the same workloads. Intel's first crack at 10nm was a jaw-dropping affair for how poorly it showed.
- steve19 8y agoSemiaccurate is anti-Intel, they are not a bias free source of information.
- robert_foss 8y agoThat may or may not be, but what certainly is true is that Intel's public messaging about 10nm production has been much less accurate than that of SemiAccurate.
- 0-_-0 8y agoYou could even say that it was less than semi-accurate
- CoolGuySteve 8y agoThe leaked roadmap is not from SemiAccurate though, it's from here: https://tweakers.net/nieuws/151984/roadmap-toont-dat-intel-in-2021-nog-desktop-cpus-op-14nm-maakt.html https://tweakers.net/nieuws/151984/roadmap-toont-dat-intel-i... If you had read the SemiAccurate article you would know that.
- kristianp 8y agoAccording to that image,10nm isn't due until 2Q 2021, in Tiger Lake and Rocket Lake U series and Y series.
- 0xcde4c3db 8y agoSure, it's due in 2021 now. At this point, Intel's 10nm has been two years away for about 5 years.
- reitzensteinm 8y agoI still remember pondering whether to delay the purchase of my Skylake laptop so I could play with AVX-512 on Cannonlake. That was two laptops ago...
- mrtweetyhack 8y agoever is a long time. I mean, given "ever", I could build 10nm chips.
