code.....................sku.....................cinebench single/multi:.............power min/max[W]

kabini....................[a6-1450].............0.33 /1.02........................ 9.2 /23.3
ivy n/turbo.............[i3-3229y]............0.40 /1.04........................11.6 /25.4
ivy w/turbo............[i3-3217u]............0.76 /1.64.........................8.3 /20.7
haswell..................[i5-4250u]............1.10 /2.44[!].....................3.6[!] /47.3[!]

how did intel get haswell idle power so low[for 1.5GHz] compared to i3-3229y and i3-3217u [tablet ready(sdp toting) y-series and the ulv-series]
then hit ~45W under strain.The dynamic range of performance and power[is there better terminology?] is astounding, arm-like power usage in powered down states but laptop class power and performance when needed.

Question, is this all due to clock gating? powering down individual unit within the soc? new process tweaks? some other voodoo?

secondly, looking the the a6-1450 and i3-3229y, it really seems like without turbo, ulv ivybridge doesn't seem all that performant [and possibly haswell although it is still faster by around 10-20%]. especially when we look at power consumption. If we were to factor in price, power and performance temash looks uber competitive and if amd introduced turbo core in their temash/kabini [2 or beema/puma?] then it will be even more competitive. why would they omit such a feature when even brazos 2.0 had it?

Jaguar does need a turbo but I guess they held that back for Beema/2.0 due to a lack of competition, making it an easy upgrade next year if they need to when Baytrail-M releases.

Turbo on CPU, GCN graphics + HSA and maybe dual channel memory should be pretty good and hold them in a reasonable position until 20nm.
