Yes ,it is very low power but keeping the mainstream performance of today's CPUs. They mentioned sub 1W power draw(idle i suppose),and pretty high OoO performance(citing "90% of today's mainstream performance levels" probably meaning athlon II),so Atom will be fighting a much faster per clock and per Watt cores,but also Atom will evolve by the time ontario cores launch.
Q&A: SOI 32nm for GPU is not "a big issue" and doesn't require major redesign for Llano production. 32nm Llano comes first.BD and Bobcat are same underlying design but developed by 2 separate teams. Bobcat uses one of the BD cores(modules) and is optimized for low power and APU integration.
edit: APU products will be refined on year basis-a bit on CPU and/or GPU side,but the new Fusion design will have a more aggressive roadmap compared to previous CPU roadmaps.
Atom, and most importantly ARM:cool:Quote:

it would be overoptimistic trying to fit x86 power needs in head-2-head fight with ARM... Intel can't do that with In-order Atom, so I don't see how can it be achieved with OoO CPU... and I'm not talking about idle power...Quote:

Is this what he said to the question somebody asked about what has been taped out? My psis poor sattelite internet (xplornet) couldn't keep up to the stream set to 50k.Quote:

I noticed that they mentioned Bobcat and BD are designed for the around the same ISA... yet the Bobcat slide only mentions SSE1-3, when Bulldozer should be SSE1-4+... So that can't be an absolute statement, as I wouldn't imagine them trying to include all of the latest extensions in Bobcat, to keep core size/power down.
Did they specifically say that Bobcat shares any pieces with BD? They said the whole two separate teams with different design points, but I don't remember them saying anything about how much implementation they shared.
Since one of Bobcat's design points is being synthesize-able, I wonder how much they're positioning it to compete with Intel's Atom. I assume AMD won't be able to license out the cores (for SoCs) to other companies like Intel will be doing at TSMC :X
No, someone asked specifically about the fact that the Fusion chips will be the first time a GPU has been on SOI and if there are any challenges I believe. They dodged the question about what has been taped out (as they don't release internal milestones) and just pretty much said things are on track for the schedule they've announced.Quote:

I think the idea is that they can combine the SIMD units to process a 256-bit instruction, or have them process two 128-bit instructions, depending on what's needed.Quote:

50% better than 45nm! That's awesome considering how good is 45nm tech especially with the latest upgrades that gave us "C3" Phenom II
coming years look exciting.. i guess i cannot not stop buying hehe

So, it will be SOI + high-k metal gate + 2nd gen. immersion lithography. Intel doesn't use SOI and they will use the immersion lithography for the first time on 32nm.Quote:

With a Fusion concept AMD might have a chance, seeing as that's what ARM offerings have right now, ie. a SoC with a cpu core plus some other accelerators (eg. Nvidia's Tegra or TI's OMAPs). However that'd require a lot of effort to pursue on AMD's part, which I would question them having the resources for at the current time.Quote:

Per Anand, all the Llano APU ("fusion") stuff in 2011 has Phenom II-based CPU cores.
So, while they will likely have a stronger GPU side, the CPU side will be about 2 generations behind Intel's Sandybridge/Ivybridge.
Bulldozer is high-end desktop and server only (at least in 2011).
don't want to go in to your need to state obvious...Quote:

there are bunch of possible parameters that could be related, but regardless it's good to hear that GloFo has mastered HKMG so wellQuote:

pfff Anand! Wouldn't be surprised if you were Anand my dear terrace215 fellow ;)Quote:
