Intel's 7nm is Broken, Company Announces Delay Until 2022, 2023 (archive)

Intel announced today in its Q2 2020 earnings release that it has now delayed the rollout of its 7nm CPUs by six months relative to its previously-planned release date, undoubtedly resulting in wide-ranging delays to the company's roadmaps. Intel's press release also says that yields for its 7nm process are now twelve months behind the company's internal targets, meaning the company isn't currently on track to produce its 7nm process in an economically viable way. The company now says its 7nm CPUs will not debut on the market until late 2022 or early 2023.

[...] On the earnings call, Intel CEO Bob Swan said the company had identified a "defect mode" in its 7nm process that caused yield degradation issues. As a result, Intel has invested in "contingency plans," which Swan later defined as including using third-party foundries. The company will also use external third-party foundries for its forthcoming 7nm Ponte Vecchio GPUs, the company's first graphics chips. Ponte Vecchio comes as a chiplet-based design, and Swan clarified that production for some of the chiplets (tiles) will be outsourced to third parties. Swan noted the GPUs will come in late 2021 or early 2022, portending a delay beyond the original schedule for a 2021 launch in the exascale Aurora supercomputer.

[...] Intel's first 10nm desktop CPUs, Alder Lake, will arrive in the second half of 2021.

    I think you underestimate the significance of that, even if only from a marketing standpoint.

    But that's the thing: There's always some synthetic benchmark you can win. But, the thing is, there's really no single threaded loads like Intel measures them in the real world. People playing fairly casual games have a browser open in the browser, possibly with a wiki page pushing ads via javascript and a p2p app throttling a few connections so that alone is a more than a couple hardware threads and easily over a dozen soft threads running in the background.

    (Zen 2 wins in IPC but can't clock as high. IPC doesn't scale linearly with clock speed, and Intel does better than AMD when it can get to ~5 GHz territory. Intel's monolithic CPUs also have lower memory latency.).

    Look even if any of this wasn't just pure synthetic results, it's still not the bottleneck. The margin for when the GPU stops being the issue and the CPU becomes the problem is HUGE. Just 3-4 years ago I've seen mining boards working 3-4 GPUs on full throttle using i3s and over a dozen using i5s.

    Really, it all just doesn't matter.
