TSMC Reveals 2nm Node: 30% More Performance by 2025:

Taiwan Semiconductor Manufacturing Co. today officially introduced its N2 (2nm class) manufacturing technology, its first node that will use gate-all-around field-effect transistors (GAAFETs), at its 2022 TSMC Technology Symposium. The new fabrication process will offer a [full node's] performance and power benefits, but when it comes to transistor density, it will barely impress in 2025 when it comes online.

Being an all-new process technology platform, TSMC's N2 brings in two essential innovations: nanosheet transistors (which is what TSMC calls its GAAFETs) and backside power rail that both serve the same goal of increasing performance-per-watt characteristics of the node. GAA nanosheet transistors feature channels surrounded by gates on all four sides, which reduces leakage; furthermore, their channels can be widened to increase drive current and boost performance or shrunken to minimize power consumption and cost. To feed these nanosheet transistors with enough power and now waste any of it, TSMC's N2 uses backside power delivery, which the foundry considers to be among the best solutions to fight resistances in the back-end-of-line (BEOL).

Indeed, when it comes to performance and power consumption, TSMC's nanosheet-based N2 node can boast of a 10% to 15% higher performance at the same power and complexity as well as a 25% to 30% lower power consumption at the same frequency and transistor count when compared to TSMC's N3E. However, the new node increases chip density by only around 1.1X compared to N3E.

  N2 vs N3E N3E vs N5 N3 vs N5 N5 vs N7
Speed Improvement @ Same Power 10% ~ 15% +18% +10% ~ 15% +15%
Power Reduction @ Same Speed -23% ~ -30% -34% -25% ~ -30% -30%
Chip Density >1.1X1.3X??

I'll wait until takyon does a review - he has a knack of sorting out useful figures from manufacturer's hype.

    Guess what Dalek? YOU LOSE, hosts work vs. Symbiote C2 server(s) per this line from a MUCH better article than the one used here from bradley13 per "configuration in the binary that used the git[.]bancodobrasil[.]dev domain as its C2 server" from https://www.intezer.com/blog/research/new-linux-threat-symbiote/ [intezer.com] (INTEZER's now owned by Microsoft iirc as well).

    & did I block that in my original posts here https://soylentnews.org/comments.pl?noupdate=1&sid=49835&page=1&cid=1253504#commentwrap [soylentnews.org] on this BOGUS sockpuppet upmodding yourselves shithole website (which also noted FIREWALLS are invaluable here too, per wildcards (or even IP address use, URL domain/subdomain too in many as well)?

    YES I DID! I was correct...

    & YES, hosts work vs. this threat too stupid!

    FACT: hosts files block symbiote C2 servers which is all you really need to do to nullify their communication.

    FACT: Exfiltration isn't possible without orders either.

    FACT: Orders come from C2 servers!

    So YOU LOSE chump... a BETTER ARTICLE than what I used proves it for me!

    * THANKS FOR LOSING TO ME yet again, as always for you... try me again? THIS COMES UP AS PROOF (as well as another I have on YOU regarding using sources where YOU contradict yourself - want quotes of that too? ASK!)

    HOW ESPECIALLY EMBARASSING FOR YOU with your NO-DOUBT self-upmodded by sockpuppet accounts of YOURSELF too - now that YOU have EGG ON YOUR FACE fucko!

    APK

    P.S.=> Do yourself a FAVOR - don't ever, EVER try me ever again OR I WILL MAKE SURE YOU SHIT ON YOURSELF yet again as always, easlly... apk
