Let's wait... maybe AMD is preparing their driver with miltithread support with Windows 10.
don't hold your breath, dx11 is old tech now.
Actually I was meaning to DX 12. AMD needs to release it for their newer cards and along nVIDIA must be ready for that.
Makes sense. Had it been significantly higher, the cat cores would serve no purpose at 15W.The MT score is rather low, barely an improvement over Beema/Carrizo-L. The MP ratio indicates some limitation like hitting the cTDP.
If the bench lasts long enough obviously the consumption is the TDP. Only in short benches where it boosts beyond TDP but the length of the benches is so short it doesn't cut back eventually is where they have an "unfair" advantage.
Not really that unfair AMD could do it to and be within TDP specs after all. AMD should maybe improve their boost mechanism just for the sake of winning benchmarks.

I didn't see it before. So there are some more results of a 15W A10-8700P accompanied by a R7 M360:
The ST score is slightly higher than that of a i3-4010U

BTW the physics scores here indicate, that the Notebookcheck results of an HP Pavilion 17-g054ng (no English product page found) could indeed be of a 15W APU:

MT score is not bad but like the ST score it s lower than what was achieved on the test plateform, or what was estimated by NBC (not sure that they did actual tests) and is achieved at 2.14GHz apparently.Cinebench 11.5 ST
15W = 0.95
20W = 0.98
At 20W the frequency stays at static 3.4GHz in ST workloads.
Meaning in this test the IPC is 9.1% greater than on Steamroller.
Probably due to combination of cTDP and single-channel DDR3-1600 memory configuration. I'd be willing to bet it's more attributed to the memory.
Counter bet: Since CB is rather cache friendly and doesn't output much per second, it's power related (cTDP, some other limit like skin temperature, maybe DC power (have to translate that article first), or even the Windows energy management settings).Probably due to combination of cTDP and single-channel DDR3-1600 memory configuration.

Other Pavilion 17-gYYYng notebooks either have Intel 15W CPUs or AMD 15W Cat core APUs, often paired with dGPUs. It looks like a NB model series for extended performance while on AC power.CPUZ will show 15W anyway since this is the default TDP of the APU.

Is this (supported by the AGESA defines) a misunderstood goal of the new "P" APUs to go to higher performance levels (incl. dGPU) when there is enough power and cooling?
cTDP, likely to be adjustable?Not bad, seems a bit expensive for 768p though. But that could actually be an advantage for light gaming. I wonder if it is 15 or 35 watt TDP. Probably not 35 in a 14 inch chassis.
Edit: nice that it is available at Best Buy.

That seems a total waste of a nice feature!probably no user accessible control exposed in the bios.

So is the official launch of Carrizo going to coincide with W10 on Wednesday? I have to assume that's the case since the notebooks have been in the wild for several weeks and I've been reading on different forums and reviews on retailers that they are being sold and purchased by human beings. Why no reviews?
Don't some ultrabook models have this option in their BIOS? If so it'd be criminal for AMD (or OEM's) not to be utilizing this for their top chips!it is a tool for the oems. 1 chip multiple, chassis.

That's what I'm thinking, why waste such an option as it can do no harm to their sales!it is up to the oems to enable such a bios option.

Are there only big Carrizo laptops? I'm looking for something like 13", 1080+p, 8 GB RAM, 256+ GB SSD, and <=1.3 kg. And with high quality display, trackpad and keyboard.
Just wait for Skylake. You will most likely see many high quality systems that fit your requirements well.
Thanks for the link. It contains more interesting information. E.g. look at the huge differences in some 3DMark subscores. That guy here possibly tested on battery power w/o dual graphics kicking in.I wouldnt hold my breath with these alleged reviews, the same guy apparently post elsewhere while recycling those pics as aknwoledged by the CPUZ shot.
Curiously he get the same CB MT score but an even lower ST score at 0.78 wich suggest a 2.7GHz frequency on ST.
The MT scores wouldnt surprise me but the ST scores seems to me doubtfull to say the least, moreover the reproducibility of the 2.22 MT is statisticaly at odd with the vastly different ST score.
