勁唔勁得過
有無 i5 desktop版咁勁?
or 35w mobile咁勁
average multi core performance
A10-5800K ~= i3-2100 < i3-3220 <<< i5 << i7
single thread performance
think it yourself
mainstream 2C4T i5 = lower clock i3 in desktop
ultra-expensive 4C8T i7 = lower clock i7 in desktop
for kaveri or any kinds of AMD products in the short term, lowering your expectation is always better. let it surprise you rather than disappoint you. I would say +30% is kind of unrealistic NOT because I am an AMD hater, but 4M4C result shows you that twice the decoders don't benefit significantly at all (but overprovision is needed as this is the price of IPC). Although I didn't account of any other potential architectural changes here, I'm pretty sure that 10% is a safe bottom line. 15% will be appreciated. above 20% will be a surprise.
rumour has it that SteamrollerB has made some changes to make it more
"competitive". at design level it seems to be a derivative of a completed rev A (linkedin info). but even we know this (I guess it is probably changes aligned to crappy GF's process change), it doesn't help much as the problem is in the fundamental of this family of architecture, and from fixing it in the HLD level to the final product shipping takes you nearly a half decade.
