#AMD’s #MagnyCours and #HyperTransport Interconnect: High Core Count Blast from the Past
Magny Cours chip is basically two #PhenomII X6 #CPU dies side by side. Two dies are connected via HyperTransport links, which previously bridged multiple sockets starting from the K8 generation.
Technologies available in the late 2000s made core count scaling a difficult task. Magny Cours employed a long list of techniques to push core counts higher while keeping cost under control.

Chips and Cheese · AMD’s Magny Cours and HyperTransport Interconnect: A High Core Count Blast from the PastBy Chester Lam

Guess who's about to discover that #microprocessors (and other chips, of course) are in ... well, virtually everything these days?

cnn.com/2025/08/06/tech/apple-

100% tariff on imported chips will double manufacturers' costs for what is the most expensive component of many products. Cars have dozens-to-hundreds of MCUs in them now, and effectively none of them are made in the USA.

Where's that Trump-pissing-into-a-fan meme when you need it...

You have to define "low". C, for example, is classically considered a high-level language, but many programmers today would bristle at that description. "Low level" used to almost exclusively mean assembly language.

Even if you don't work in domains where low-level languages are required, I think it's still valuable to learn. The lower you go, closer to the metal, the more "think like a computer" you have to do. And getting a good feel for that can help you with writing code in any language, high or low.

This months project: Month of b4CPU

edave64.github.io/b4CPU/

This is a 4bit #CPU simulator I started with a friend a while ago, but was then left abandoned as a private repo for two years.

This is a project very close to my heart. It is designed after a tool called "Micro", an old windows 3 program we used in school, but that I was never able to find again.

But it was the moment where how a CPU works finally clicked in my brain, so I wanted to bring it back for others to enjoy.

So, nach ganz viel Recherche über die CPUs in Bezug auf meine Anwendungsfälle für den Rechner und auch die Sinnhaftigkeit von #Thunderbolt für mich, ist nun eine Entscheidung gefallen.
Ich werde mir einen #refurbished Thinkpad T14 Gen 1 kaufen. Er hat eine #AMD Ryzen5 Pro 4650U #cpu
Speicher 16GB, SSD 512GB
OS wird Linux Fedora.

Ich tue mich mit solchen Entscheidungen immer sehr schwer und muss alles immer mindestens 10x von vorne, hinten, rechts, links, oben und unten betrachten.
