AMD "Piledriver" refresh of Zambezi - info, speculations, test, fans

[informal]

I sense disappointment in the air.

What are your expectations then? It's just a tweaked Bulldozer. If you expected a 25+% performance jump out of it,sure ,you will surely be disappointed. The chip will offer 11% base clock uplift and (rumored) no Turbo clock uplift. Also it will offer moderate(~6-8%) IPC uplift. All combined ~15% performance jump over 8150,just about enough to beat 260K in application performance (not games though). It's not going to be a monster performer but a decent one for the money.

from an abstracted architectural standpoint i struggle to even call it a tweak. From a physical implementation point of view its far more then a tweak. Also the thing to remember is this piledriver core is a different one to trinity (likely just a new steeping) with the big change being additional memory instructions for the AGLU's, but dont be surpised if there is a little bit more improvement in clock scaling then trinity.

also even by your maths its 19% perf improvement not 15%.

I thought the biggest change was the new resonant clock mesh design?




The thing that sucks most though is that if we get the promised 15%, and we get an additional 15% each year with the new models then Intel will probably be 30-40% faster still by the release of the 2014 model. Intel isnt just going to be sitting still so AMD can catch up. So while I enjoy a lot of AMD products, we really need something major in Steamroller or AMD will be behind until middle of 2015 at the very earliest.
