AMD Zambezi news, info, fans !

[informal]

What we have been promised:
-higher or equal IPC (AMD HC22 presentation, AMD bulldozer blog,JF blog and posts)
-more cores(33% more)
-more clocks
-overall 30-50% more performance in the same TDP envelope than previous design

What we got as a final product:
-lower IPC,ranging from 10 to 25%!
-more "weak threads" that in many workloads barely beat X6 at lower clock ( weak threads are direct result of much lower IPC than K10even 4.2Ghz Turbo is not enough to offset this)
-higher clocks with much higher power draw under load (this can be GloFo's mistake for all we know)
- overall around 10-15% more performance vs 1100T

End result: we practically got 8 Bobcat cores (which are sometimes slower per clock than real Bobcat!),higher power draw than 1100T which can clock rather high (with astronomically high power draw when you do that).

With AMD's projected IPC improvements(now to be taken with much salt) ,even Steamroller will not be able to beat Llano which is around 7% faster than Thuban at around same clock while having no L3 cache at all.This is major fail I'm afraid. For desktop at least. For server I suppose they can do fairly well in SOME workloads,but overall they will be just a tiny bit better than where they were with MC. 2B transistors and this is what we get...

Oh my...Loooking at benchmarks this morning, I was remembering all the discussions with you over the past 18 months about BD....Well, we can't be both right at the same time.


Hardware Canucks did some pretty good comparisons :

PS : You should change your signature, someone was right and you and others were terribly in the wrong.
