AMD's Fusion APU Pitted Against 21 Desktop CPUs 93
crookedvulture writes "When AMD unveiled the Bobcat CPU architecture behind its first Fusion APUs, the company claimed its Atom-killer would achieve 90% of the performance of mainstream desktop processors. But does it? This article compares the AMD E-350's performance to more than 20 desktop CPUs between $87 and $999 to find out, and the results aren't particularly encouraging. Although Fusion offers much better integrated graphics than Intel's latest Atom, neither stands much chance of keeping up with even low-end desktop CPUs. The E-350 does offer very low power consumption and impressive platform integration, making it a good choice for home-theater PCs and mobile systems. Desktop users are better off waiting for Llano, a Fusion iteration due out this spring."

Because you make a very different chip if you're aiming at 9 or 18W vs 60 or 80W.
Put all those desktop chips in the same power envelope as Bobcat, and they'd suck ass. Give Bobcat the power headroom of the desktop chips' environment, and it wouldn't know what to do with it.
The results as far as I can see are pretty good, given realistic expectations. Of course the article points out AMD claimed 90% of desktop, which just might be where some unrealistic expectations came from. Knowing AMD, that probably wasn't completely bullshit. It was probably a statement about IPC at equivalent frequencies, not delivered performance at their respective TDPs, possibly confused by a PR person, with a bullshit multiplier in there somewhere. ;)
Re: (Score:3)
A fair point that TDP isn't the whole picture, and I didn't say anything about die area ergo cost as a distinguishing feature of the market Bobcat and Atom are going for. I'd believe it does do better with a bigger core and lots of die space spent on 3.5MB of cache. It would have been interesting to see it in this comparison.
Though the conclusion would have been the same, as clearly a $250 part is not competing in the same space.
BTW, you seriously need to stop projecting.

It seems to me the real problem is that they stuffed a discrete GPU into the thing and then tried to compare it with desktop systems with discrete GPUs. That isn't the usage model for these at all. These only have 4 PCI-e lanes. Look at page 16 where they start to compare it with desktop systems where they're all using integrated graphics -- it comes out far closer.
