Wikipedia lists Intel 3 is roughly the same tech level as TSMC 3nm [1], but without listing transistor density. Intel is producing the Xeon 6 using Intel 3 [2]. So arguably Intel has a more advanced process in the USA than TSMC, which is doing 4nm in the USA next year. Intel's production is probably not very high.
Wikichip is my go to (which is down right now for me unfortunately). It’s important to look at the latest data because Intel’s internal nodes real specs have not met the stated expectations recently
I'm not refuting the statement, only pointing out that density is not the only factor.
Unfortunately, these numbers are arbitrary and companies are guessing what performs about like what based on numerous factors. Often wrongly - Samsung's equivalents were so bad Qualcomm pretty much abandoned them, and for good reason. Anyone who used an Exynos or SD888 understands why.
I feel like we should have landed on a better tracking system now, like perf/watt, but here we are.
That was before Intel renamed their process nodes. They went from being 1 node more dense to being 1 node less dense with their new naming scheme. You need Intel 4 to match TSMC 5nm.
But for those living close to the plant, I'm not so sure:
"Environmental, and public health groups, including the Sierra Club, are urging President Joe Biden to veto a controversial bill that exempts most semiconductor companies applying for federal CHIPS Act funding from having to complete essential environmental reviews, as required by the National Environmental Policy Act, or NEPA."
“Exempting the semiconductor industry from NEPA is completely unwarranted, especially considering the projected significant increase use of PFAS and other toxic chemicals by the industry and their track record of releasing these dangerous chemicals into the air and water surrounding the facilities,” said Tom Fox, Senior Legislative Counsel at the Center for Environmental Health"
Having lived next to the Motorola EPA superfund site, and more recently closer to the TSMC site, I find no consolation in your reply. The lack of transparency and accountability is too great.
