TSMC N5 is a 2020 node. Reaching parity with it three years later isn't really a good look for Intel on the fab side. While AMD is their main competitor in the x86 space, their fab competitors are TSMC and Samsung regardless of who uses their nodes. N5-family nodes will still have a massive cost and yield/maturity advantage over Intel 4 in 2023. 2023's Meteor Lake launch will be quite a teaching moment as to the true state of Intel 4. Pay careful attention to what SKUs they do and don't release on Intel 4, and keep in mind how many products have been moved to some other node (Granite Rapids, etc.)
I believe the main nodes of IDM 2.0 that Intel is pushing is Intel 16?, Intel 3, and Intel 18A. Those nodes seem to be pushed because they are the further iterations of the node behind them, rather than an entirely new node. Maybe they aren't pushing Intel 4 much for IDM 2.0 could be cost, sure, but also because Intel 4 doesn't even have complete libs, it's just high perf cells.
This also connects to why Granite Rapids might have been pushed to Intel 3- not necessarily mainly because of the progress of the Intel 4 node itself. We have a couple reasons here:
In complete libraries for Intel 4 (Dr. Ian Cutress theory)
SPR delays means that SPR 2023, EMR 2023 end/ 2024 early?, GNR HAD to be pushed back regardless, and considering Intel 3 is a reiteration of Intel 4, why not just push GNR to a newer node if it's going to delayed a year or more regardless?
GNR got 'redefined'. New architecture+node as well. AMD themselves (Norrad) said they expected genoa to compete against GNR, but it's pretty clear now that GNR is going to compete against Zen 5 server products. GNR had to be redefined and improved somehow...
Intel also doesn't produce small die pipe cleaner mobile chips to sell at large scale as well, so for them yields and perf have to be better earlier than TSMC and Samsung for the same node.
What really is a bad look though is that despite Intel 4 just catching up pretty late to the party, is the fact that if Intel executes, they can catch up to TSMC relatively quickly, in the next 3 years or so.
For Intel's means and purposes, Intel 4 is pretty competitive. Especially since, even as a foundry, Intel doesn't even seem to be really pushing Intel 4.
