AMD Benchmarks Zacate APU, 2x Faster GPU Performance than Core i5

[flyck]

First, the Llano specs seen in this thread are pure speculation. But let's pretend they are real. Then you still have different TDP ranges. And I'm sure that a Llano part at 2.6GHz will be a lot "hotter" than a 1.6GHz Zacate. You have much larger cores originating from chips developed with servers in mind against a very small chip made to be extremely efficient in perf/w. Even if Llano is power optimized it simply can't be cooler than Zacate.
Even if there were a Llano at 20W TDP, it's still just TDP. Chips made at the same TDP can have significant differences in power consumption. The TDP-ranges are simply not in a resolution high enough for such comparisons.

In an poor attempt to explain let's pull some numbers out of my arse here.
18W TDP Zacate could mean 10W theoretical max, 7W real world max, 3w typical and 1w idle. A 20W Llano could mean 20W theoretical max, 15w real world max, 11w typical and 8w idle.
These numbers are of course pure fantasy, but my point is that TDP-ranges could mislead, one watt in theoretical max is enough to be put in a range with twice as high TDP number. And TDP don't show how efficient energy saving there is. A Zacate will probably have much better idle and low usage powers than Llano due to the very different bases for their design.

And then again, even if a normal Llano at 45-65w probably could be reasonably priced around 150-200usd for notebooks, a 20w ULV would be rare and thus priced a lot higher. At the same time Zacate and Ontario will be so cheap to produce that AMDs people could wipe their behinds with them if they had skin thick enough.

So, even IF a 2.6GHz Llano with 20W TDP existed. It would be much more expensive since the chips good enough would be rare, and it would probably use a considerable amount more power than a Zacate in real world, especially in idle and normal use.

Just for the record... if you read my posts you would know that i allready said all that... I always mentioned if it were true (and i don't believe that) and that tdp is the same but zacate will have the advantage at lower loads.

@ other: 18W ULV cores exist now and will exist again with SB. Atom is nowhere near the 18W picture it isn't even in the same tdp range as ULV cores. Zacate will have stiff competition from much better performing parts who cosume only a tad more(yes cpu only the difference is big, but with everything else connected the difference is still the same but the overal powerdraw is bigger. so in % it is only a tad). (again referring to the 5times i allready mentionned if those figures would be correct and i don't believe it). This would imply that either you go performance llano/ULV or power zacate. These are 2 products relativly close to eachother where the lowest has the least margin. So if you are lucky and take a huge share of ulv the cpu is worthwile, but llano for that tdp will not as it will have almost no marketshare left (shares with ULV). If most people choose for performance in that sector the reverse is true. llano with huge margins will compete better and zacate will only supply the very few. which makes it a really nice market. Hence, i only expect Zacate to be released for this part of the market atm (while it still open due to bad graphics from intel) and will be downsized from then on (or boosted more to replace the ulv of AMD). Ontario will be the main focus of the platform and the prophet.

but since we don't even know the specs of Zacate, let alone llano which is sheduled alot later. Things will flow as they flow. I just believe Ontario (the very low power) part of the platform will know more success than Zacate which was demonstrated. Just hope that ontario isn't to much slower than Zacate.
