This is a new article about the historical usage of 28nm.

I checked the title, the 28nm and the date of the article.

It's more of like documentary writing on 3-4 generations old architecture. The opening statements clearly indicate why they published

On a related topic: does anyone know why NVIDIA keeps reducing the bus width on their latest gen cards?

A 2060 has a 192-bit bus.

A 3060 has a 192-bit bus.

A 4060 has a 128-bit bus!

###

A 2070 has a 256-bit bus.

A 3070 has a 256-bit bus.

A 4070 has a 192-bit bus!

Indeed. These are cards from ~2012 (Kepler came about with the GTX 600 series).

AMD isn't asleep. MI300x announcement on Dec 6th.

How is AMD addressing CUDA dominance?

Build a developer flywheel by making ROCm more accessible.

That said, I'm approaching this from the other end, by make their high end GPUs available to developers.

Samsung has a fab. Anyone knows why they don't want to enter the game and create an AI chip.

Create? Perhaps lack of IP/talent. The exynos chips have been lagging a bit behind last I checked. However, they are adding capacity to their fabs for AI chips, so it’s possible they may be planning one in the future. https://www.digitimes.com/news/a20231121VL206/samsung-electr...

GPU architecture is just a simple core repeated a gazillion times plus some memory bus.

Intel was infected with marketing people who diseased the entire C-Suite and drained the company for 8 years without doing anything other than make up new marketing names for the 5000-11000 series of chips and their stagnant iGPUs. That level of thievery would kill any leading company. ..

Intel actually did a lot in the last decade. Skylake alone was a massive improvement over the previous generation. AVX-512, countless open source projects—not to mention Optane, which was one of the most radical innovations in hardware in years. They did some really cool stuff with Altera IP, but the market didn't really care for it as much as it probably should have. Much of the value of Mobileye happened under Inte…

> Intel actually did a lot in the last decade.

That's the expected case when you have tons of cash and market dominance.

> are making a reactionary take about the lack of post-Skylake microarchitectures

Or about the general inability of large monopolies to effectively compete and continue to deliver according to market expectations.

> or years because they care about video games more than safety.

And yet, they still had a "server chips" division for much of that time.

Wafer prices have increased and so has Nvidia's greed so you get less hardware for your money every generation.

....which is hilarious because later on, the 580 had the same TDP as the 1070ti, but half the performance.

I guess the only thing you’re missing then is the content of the article. ;)

Well AMD marketing turned out to be a joke, remember Poor Volta? I still think AMD haven't even recovered from that. There marketing for GPUs have been terrible since.

You mean Vega. Volta is a Nvidia arch.

Vega's marketing pushed Nvidia to make what is ending up to be the best product series they will ever make: series 10. That isn't much of a joke, it scared the shit out of Nvidia, and they blinked.

Vega was too late in the pipeline to stop, and Raja was ultimately let go for his role in the whole thing. He refused to start making more gamer-friendly cards, and was obsessed with enterprise compute/jack of all trades cards.

Immediately afterwards was a pivot towards a split arch, allowing multiple teams to pursue their intended markets.

Its why AMD won against Nvidia. Nvidia still has no real answer to AMD's success, other than continuing to increase card prices and making ridiculously large chips that have poor wafer yields. Nvidia won't even have working chiplets until series 60 or 70, while AMD already has them in a shipping product.
