AMD did a major re-architecture, with the server "chips" having four 120-thread actual chips communicating through a system controller, just like an old parallel mainframe. This all fit in one chip carrier: I'd have loved to see how the interconnects worked, but they were pretty closed-mouth about that They did admit the first generation gave up about 15% when you made two of these coordinate with one another via a cache-consistency chip. I'm waiting to hear about the second generation I suspect the new low-cost chip is a simplified version of one of the four processor cores, and might cost about 1/5 of what the server chips cost to make. --dave On 2020-05-08 10:55 p.m., Nicholas Krause via talk wrote: Seems AMD is launching around low end processor line: https://www.guru3d.com/articles-pages/amd-ryzen-3-3100-and-3300x-review,1.ht...

Why Failed? Each Zen 2 package is made from a group of "chiplets". Each processor chiplet (CCX) has 4 cores, with each providing 2 SMT units: 4c 8t in current notation. AMD uses a 7nm TSMC process to make them. Then they have a chiplet or several to do I/O. Density doesn't matter as much here so they are made using something like a 14nm process. So: a low-end Zen 2 package has fewer chiplets. It probably has a lower clock speed. AMD might "bin" them for speed. That means: manufacture them, test how fast they can run, and sell the faster ones as separate SKUs.

That's what I was thinking of when I said "simplified". --dave -- David Collier-Brown, | Always do right.

Hopefully this does happen but I'm assuming it will take a few years or so. Through I would mention the extra 20 dollars on the 3100x is worth it due to it being one module if you know about AMD'S CCX interconnects. Its similar to NUMA but on one chip for those who don't know.

Hopefully this does happen but I'm assuming it will take a few years or so. In an earlier life, we noticed a huge increase in usability going from a single core to a dual-core processor in desktop SPARCs. Having two processors available to respond to a request means way more that you'd expect in responsiveness. Somewhat underpowered workstations felt as if they were big multiprocessors. Joyce noticed, and bought me a "Tadpole" UltraSPARC-1c laptop for a birthday present. --dave -- David Collier-Brown, | Always do right.
