If we are just looking at the fabrication process, as opposed to CPU architecture, MTr/mm² – million transistors per a square millimetre. But transistor density can be variable depending on the type of circuit, so the standard calculation uses a weighted average of two different cell types – NAND2 and SFF (scan flip-flop) https://en.wikichip.org/wiki/mtr-mm%C2%B2

A while ago, I just tried taking any figure I could find for transistors per area, for various processes/chips, ignoring all the nuances, and taking the square root to get the implied linear density, and if I recall correctly, it was pretty consistently 1/10th of the usually quoted figure. Whatever the ratio was, it seemed to be roughly consistent going back like 30 years, which surprised me. So now I don't believe t…

If you were comparing it to the Nnm figures, that actually checks out and is higher than I thought it would be. Nnm has been "feature size" not transistor size for eons now. It's the size of the smallest single shape the process node can do. So, like the width of a corner of a fin on a finfet.

Samsung has a dishonorable marketing department. 3nm is not actually 3nm. I'm fed up... OLED is superior so they had to take the path of calling theirs QLED which is actually just an LCD screen with phosphors on top of a blue backlight (and it's nothing new).

I agree calling their display tech QLED is pretty shady, and clearly just intended to confuse people. But I'm glad their high end display tech is not OLED yet, because nobody seems to have solved burn in satisfactorily yet (if you play a lot of games or use them with a PC).

There’s an lg oled soon to be released that “solves” the problem by basically underscanning and using the unlit pixels at the edges to allow for much more significant pixel shifts. It’s this one, but I can’t find the review. https://www.dpreview.com/news/0394947539/lg-new-32-4k-ultraf...

I wonder if that is some kind of cultural shift that is taking place that started around 2009, or if it's always been like this and I just never noticed.

I've been using an LG OLED for 5 years with an HTPC. Lots of gameplay and leaving it on all day with eg a web browser open. I haven't experienced any burn in.

Would you mind taking a photo of your TV showing a 50% gray screen?

oh god, I shudder at the thought of trying this test on my old screen because I know what the result is going to be like.

I thought the Q stood for quantum dot, which they actually use? (Not that that makes them unique nowadays).

Yeah but do you really think they didn't choose that acronym, with that upper case Q with no intention to make people think they were OLEDs/similar to OLEDS. QLED OLED

I Really do think so. Because it's exactly following the naming standard of existing displays. Go to Walmart. Go to the TV section. You see all those LED TVs? They're both LCD and LED. That LED portion is used for a light source.

Q stands for Quantum dot, which is another grid layer on top of the LED layer, to improve that LED light. The reason for the upper case Q, is because upper case is just how acronyms roll.

Now, tell us about jew space lasers starting forest fires.

To be fair, I read the Xnm labelling is pretty much pure marketing at this point - since 45nm; https://en.wikichip.org/wiki/technology_node#Meaning_lost

It doesn’t relate to any measurement of feature size. It’s just a frustratingly meaningless marketing term.

Why do we keep using it?! It’s so unscientific that it embarrasses me that intelligent people even talk about it.

It’s basically like a version number now I suppose.

I can never remember what xnm means as it varies between companies. In this case, Samsung's 3nm = Intel's 7nm I am still waiting for a standard based on transistor density numbers!

Intel actually renamed their nodes in like with Samsung and TSMC, so Intel 7 (used to called 10nm) is roughly comparable to TSMCs 7nm and Samsungs 8nm

there was a restaurant, a&w I think, which had a 1/3lb burger. a whole bunch of people thought it was a ripoff - smaller than a quarter pounder. As it's impossible to explain to the masses that they need to repeat 3rd grade, the restaurant gave up on the idea.

then there was windows. have you actually heard an elite hipster tell you, a professional highly paid tech guy, that mac is superior because windows is behind on operating systems? not because unix is better. no, because windows was "8" and mac was "10." X is the roman numeral for "10" you see, and 10 is a later version than 8. So ms ended up skipping windows 9.

There was a defined standard for process sizes. A bunch of unethical marketing scammers used half-truths to scam people. It worked, because people can't even figure out a hamburger. And now the people who followed the long-established standard have to switch to the scammer's standard, because they still need that hamburger guy's money.

Here's the problem with customers... You need their money.

Their high-end phones have such dark patterns that I will flat-out not buy Samsung anything. Even if you pay [€$]1000+ for one of their Smart Phones, you can look forward to: * Uninstallable cruft, as if they were a telcom and you were on a contract and had not just handed over a grand * ...like a confusingly-similar-looking competitor to Google Contacts that will upload your info to their servers * GDPR? LOL * A har…

Also, add that you can't believe in any promise about updates of his phones. I did one time, when they launched his phones with Bada OS. Never again.

First though, "5nm", "3nm" and so on are just marketing names. There is nothing about "5nm" that makes it "5nm" other than the company in question saying it is. Some things are smaller than 5nm on a given 5nm node, and some are larger. I cannot recall exactly what node this started to be the case (there used to be an actual definition, one for DRAM, one for logic), but it was in the past two decades and got particula…
