AMD Details ZEN Microarchitecture IPC Gains

[BiggieShady]

A bit off topic but I was just reading this:

"The Plus Side of AMD:
Some benefits that AMD processors come with are that they run cooler in your system and are then more quiet and use up less power."

Ha, that cracked me up, intel cpus are fin fet since sandy bridge with increasingly higher transistor density in lower overall area and thus higher thermal energy concentration and more difficult cooling (even with lower TDP) ... amd cpus are easier to cool but also have much lesser max allowed temps ...

... seems finally zen's gonna change things for amd

Question for the Author or anybody that my have an answer. Will ZEN be using Hyper Transport Technology? I visited the website and the latest upgrade was in 2009 HTT 3.1.
They also have something called Hyper Share.

HT replaced by Coherent Fabric http://www.anandtech.com/show/10591...t-2-extracting-instructionlevel-parallelism/5

Might be Freedom Fabric IP acquired when they bought Seamicro http://www.theinquirer.net/inquirer...cense-seamicros-freedom-fabric-to-cpu-vendors

Larrabee was not a GPU.
It was an attempt to build something rather different, with x86 instruction set and idea that specialized hardware for z-buffering et all is not needed and it's better done in software.

It was basically a bunch of (simpler) x86 cores.

It would trounce usual GPUs at stuff like ray tracing and yadayada... but in the end Intel abandoned the idea as it didn't quite perform as expected.

Even Intel were confused http://www.cnet.com/news/intel-initial-larrabee-graphics-chip-canceled/

Or not, my past self, you'll read this in your future: http://www.pcper.com/news/Processors/Leaked-Geekbench-Results-AMD-Zen-Performance-Extrapolated
(huge grain of salt here is the fact that most geekbench tests fit completely into L1 cache)

Might as well run 2004 PCmark lol.

2004 PCmark? The one where 6 GHz Phenom2 matches 5 GHz Ivy Bridge ... dunno, people are hoping geekbench results are worst case scenario, not the best case scenario
