Yes, but what it has to do with the Raptor Lake preview link/conclusions that i quoted?
It's one advantage of Zen4 for those that use programs build around AVX512 instructions, so i guess it will benefit in a similar way as Intel's 11th gen Rocket Lake did, zero benefit for gaming, and even in commercial applications like Blender that use AVX512 in some tasks, the difference is small in most cases, you have to go very specific "scientific" apps to see big differences.
But nonetheless it's a welcomed advantage of course.

Yeah a downside of rapid product releases, if I was a retailer I would be really paranoid about ordering too much as a new gen is always round the corner.

Alder Lake is so new we're still waiting for availability of 12th Gen laptops. A few select models have made their way into the hands of reviewers and popular YouTubers but that's about it. How are stores supposed to be buying 12th-Gen inventory when Intel is preparing to launch 13th Gen and claiming, obviously, that it's better?

Its as if there is no communication between the marketing and product designer guys with the distribution and sales guys so are completely out of sync with each other. Putting out a product to review that cannot be purchased is mind baffling, the only thing it might do is cannabilize sales of your last gen products.

I mean I waited an entire year for a Renoir 4800U laptop to become available to buy after reading a review in March 2020. It never became available and I settled for a 4700U.

Now I'm super excited to buy a 6800U laptop which was launched and reviewed five months ago. Currently the only one available is a dinky little 13" OLED one with piss-awful cooling and OLED burn-in. Where are my regular 14", 15.6" models without OLED that normally make up about 98% of the models people buy? Five f*cking months and nothing really even announced yet from Asus, Lenovo, Acer etc. They're still pushing 5000-series laptops with awful Vega graphics that we had 4.5 years ago.

If you went into a store after reading the launch reviews of the 3080 and the best they could offer you was and 4.5-year-old GTX 1080 from two generations ago, you'd be equally annoyed right? That's how it is with most AMD laptops and a solid majority of Intel laptops.

Yeah I recall looking for a new laptop a couple of months ago, wanted a modern AMD one, all I could find was older intel, and one manufacturer alone (seemed to have exclusivity deal with AMD as was the only one) had stuff for sale but the price was insane probably due to the limited availability.

I don't exactly understand what you meant. TSMC has several modifications of the N7 production lines:

7 nm process - Wikipedia

N6 is nothing but N7++.

I think it is mostly a nudge towards more efficiency while maintaining / slightly improving the density. More EUV less DUV, or fewer masks/layers.

The advantages cannot be understated, because fewer steps towards a full chip is a boost to yields and to quality of the silicon. So an N6 process might very well clock a lot higher, for example. Its not just about density, its about consistency.

Take note of the power envelope on Intel's '7'. Its not pretty, it won't really clock that well above 4.8~5.0 Ghz. And it took them a LONG time to get there, even so, when they do, its grossly inefficient.

Similarly, compare TSMC's 7nm GPUs (AMD) versus Nvidia's Samsung 8nm GPUs. The former is built up out of (part) EUV. The latter is DUV. We're looking at gaps of 500mhz and more. The TL DR here is that even if you 'shrink' chips based on DUV patterning they won't quite work as you'd want. Its clearly the end of DUV to facilitate further 'true' shrinks that make economical sense.

That is in a nutshell, the whole reason Intel stagnated beyond 14nm. Going smaller on DUV is absolute hell. And it is why Intel is moving as it does today. They saw what TSMC realised first, and have admitted defeat by embracing EUV, and even pushing it harder than TSMC wrt testing new aperture sizes and stuff. They want that node advantage again.

Game development is largely dictated by game consoles and the current-gen consoles have AVX2 support.
