AMD Ryzen

Hi all

So as the title suggests, AMD's new desktop CPU family ("Zen") is going to be called Ryzen (that's pronounced "Rye-Zen" not "Ri-Zen").

Here are some articles covering it:

AMD crests Summit Ridge with Ryzen CPUs - The Tech Report - Page 1
AMD Gives More Zen Details: Ryzen, 3.4 GHz+, NVMe, Neural Net Prediction, & 25 MHz Boost Steps
https://www.pcper.com/reviews/Proces...d-more-details
What we know about AMD's Ryzen so far | PCWorld
AMD's next-gen Ryzen: biggest leap in CPU tech in years

And the key points IMO:
  • At base clock (they're keeping the boost clock a secret for now), their new 8-core is comparable to the $1100 6900K at boost.
  • The new "SenseMi" technology will automatically overclock the CPU to fill available cooling headroom. Stick an AIO or a tower cooler on there and the CPU does the rest.
  • SenseMi also features (in their own words) "Scary Smart Prediction" which is a ‘true artificial network inside every Zen processor that builds a model of decisions based on software execution’. It sounds like what this should mean is that the processor will be more efficient by predicting some instructions.
The Specs:

Re: AMD Ryzen

I like the name RyZen!

The TDP is impressive; this could be a real competitor with aggressive pricing.

Scary indeed.

On a serious note, these predictive algos usually end up making the overall performance worse in real world use. We need to wait and see how good it is.

I can see how it might be useful for a work computer, which might be used for a relatively small set of tasks most of the time. But I was thinking about how erratic my own computer use is, and I'm hoping this technology can be disabled or at least "reset" every once in a while.

Also, if it's learning, where does it store the information it has learned? In the BIOS? A hidden partition on the SSD? Within Windows itself? If so, how compatible will this be with Linux and other OS's? Come on AMD we want answers
