What about Ontario?

[richough3]

I'm glad we got some Zacate numbers, but I was more interested in Ontario. What can we expect from the 9W part? I saw a slide that indicated a 1.0 GHz dual core but I don't know if that was true or not. Does anyone have more info?

CPU-wise I'd say it should be a good deal quicker than Atom, only thing I've seen has said a 1.6-1.8Ghz Bobcat should be just a little slower than a 1.6Ghz Core 2, so that brings it close to IPC parity with K8, which I know at 1Ghz stomped on Atom (don't remember where I saw that.).

GPU-wise, it should be much better than Atom.

Though I am lax to admit this, if Bobcat performs as well as is rumored/estimated, it'll be one heck of a feat of engineering on AMDs part. The CPU cores are some 60% the size of Atoms, and while the GPU is massive, it's performance should be more than adequate and in a 9w power envelope, very impressive all around.

But I don't think we have much in real information, yet.

18W @ 1.4 GHz is terrible. Even the Athlon II Neo K325 is only 12W @ 1.3 GHz, thus the 1.0 GHz Ontario is the more attractive part, but what about its performance?

For the heck of it, lets look at the leaked Ontario benchmark that showed 3047 GIPS/1351 GFLOPS vs the Atom D510's 1892 GIPS/735 GFLOPS. The processor speed indicates 1.4 GHz - 1.6 GHz for the Ontario benchmark.

Just doing simple math, but assuming it's numbers for an Ontario at 1.6 GHz (worst case scenario), take the numbers and divide it by 1600, then multiply it by 1000, then we have 1904 GIPS/844 GFLOPS. That would put the 1.0 GHz Dual core Ontario CPU performance on par with the Dual core Atom D510. And at 9W Ontario vs 13W Atom, the Ontario would definitely have the advantage in battery life in addition to better graphics performance.

The other question is what is the price difference going to be between regular DDR3 and LVDDR3.

I would guess that the TDP's aren't accurate as to actual power draw. I mean, how can they put out a 1.6Ghz dual core + GPU at 18w alongside a 1.4Ghz without? I'm definitely going to be waiting until we get benches.

richou3, you are forgetting the 18W includes a rather poweful GPU. TDP is quite accurate at estimating load power actually.
