Intel are so lucky that their fab issues have come at a time when AMD physically cannot even dream of shipping enough chips to make them bleed.

That being said I think Intel only have to get their act together once to get right back in there - they have dragged 14nm all the way, their uarchs can't be that bad.

It's easy to underestimate just how difficult processor design is and just how quickly it has advanced over the last few decades. First you have to design an incredibly complex custom hardware processor to implement your ISA of choice with various speed optimisations. Then you have to convert it to a gate-level model and simulate it to make sure it's reliable. Then you have to produce a physical/electromagnetic model…

You also have to be able to verify (at least the important parts) of the chip

Offtopic: Most might be thinking fully FLOSS is something that's only happened in software, or powerless hardware. But the thing is server and desktop grade powerful and fully FLOSS hardware with PCIe 4.0 and DDR4 ECC memory are available right now to customers and businesses. Not as powerful as AMD. AMD will never be open though. It's not x86. POWER9. FSF RYF certified. https://www.raptorcs.com/ #talos-workstation o…

I like the idea of FSF-certified hardware, but aren't POWER9 machines ten times the price of the average desktop?

Doing a quick spec out of a Talos II that is similar[0] to my Threadripper 3970x workstation puts the price at ~2x.

What 'smcl' commented, also all prices are in this link, scroll down: https://www.raptorcs.com/

Thanks. Looks like their cheapest system goes for $3,404.59. It has VGA output, but no DVI/HDMI/DisplayPort.

Strange: the price on their systems seems to have gone up since the last time I saw them.

I wonder if shipping issues have caused their prices to skyrocket recently?

Does anyone know if AMD has any sort of strategy around Thunderbolt for their mobile chips? Are they stuck because of Intel IP issues?

Their desktop lines are basically the best you can get (assuming you can find anything in stock), but even the latest 5000 series laptops conspicuously lack Thunderbolt. This makes them a tough sell for some, as Thunderbolt has become the defacto standard for modern docking stations...

I can't get past this sentence:

> From these humble beginnings, and a quick move from Santa Clara to Sunnyvale (Silicon Valley in California)

Is the rest of the article better than this?

For those outside the Bay Area: Santa Clara and Sunnyvale are physically adjacent, and I'm guessing all of the sites where AMD's HQ has been historically located are probably within 0.5 miles of each other near that border.

It is the coolest shit we have, right? Do we have anything else that is as advanced/complex/refined/whatever-you-wanna-call-it?

It's certainly the highest precision manufacturing you are going to find in a consumer widget. It's hard to think of anything manufactured to sub-nanometer tolerances. Maybe some scientific instruments like large telescope lenses?

Got myself AMD FX-8350 a decade ago, used it daily with minor overclocking and replaced with Ryzen 3950X last year. This old FX-8350 went into dedicated Linux machine for things I weren’t able to do with virtual one. I am curious how long will it run:-)

Those FX series had a really bad reputation at the time, but it seems the extra cores have helped them age better than might have been expected. My old FX 6300 is also in a Linux box now hosting a Jellyfin server and it does quite well!

Ha, I was just about to mention the FX-6300 I have running in a server that hosts 3 Minecraft instances. It's not the fastest thing ever but it gets the job done. I was going to replace it when it got too slow, but that hasn't happened yet.

It is hard to understand today, but back then every manufacturer of a chip design needed a "second source", a fully independent competitor who could supply a compatible chip. Otherwise it would be far too risky to design their chip into your product. What if they folded? AMD, by cloning the 8080 and other chips, gave Intel what it had to have to be a serious supplier for serious products. The 6502 succeeded by being…

Second sourcing was a requirement imposed by the DoD.

A simple, yet very powerful, weapon for ensuring a healthy economy. Having at minimum two potential sources for any component in the economy, with anything that can't afford that classified as a Utility and regulated as such.

From the single or none fulfillment of broadband options in the US even in dense suburban areas, let alone rural areas, it is clear that there are places in dire need of similar government market regulation.
