Kabini: Competing in the Evolving Marketplace
Prior to the onslaught of Android tablets and the launch of Windows 8, I was pretty much done with Atom and Brazosthey simply didnt provide enough performance to make them pleasant devices for me to use. What was rather anemic hardware for Windows Vista/7 starts to look much more palatable with the new OS, and Android on such a chip can run extremely well. AMD has Temash for that audience, but I suspect well at least see some 15W Kabini tablets/hybrids at some point, and they should stack up quite well against the competition in terms of performance and features. Thats the real takeaway from todays launch, and it shows that AMD is keen to carve out a market niche separate from the traditional desktop and laptop PCs.
In terms of the normal Windows experience, Kabini doesnt make too many waves. Yes, its faster than any current Atom or Brazos laptop, and Windows runs reasonably well all things considered, but there are still applications where Kabini falls short. That's the problem with competing in the good enough part of the computing spectrumeveryone has a different definition of what's good enough.
CPU performance is appreciably better than anything Bobcat or Atom based at this point. If you're ok with Clover Trail, then Kabini will feel really quick. The big Ivy Bridge cores still maintain a significant performance advantage, but presumably Kabini's offer is that you can find it in an Ultrabook-like system but at a much more reasonable pricetag. If that ends up being the case, I suspect many would choose form factor over extra CPU performance. So much of Kabini's success will be tied to what OEMs do with the parts. It's unfortunate that AMD doesn't have any Kabini APUs with Turbo Core working as I suspect that could do wonders for further driving single threaded performance.
On the graphics front, Kabini's Radeon HD 8830 is stuck between a rock and a hard place. It's significantly faster than what we had with Brazos (and lightyears ahead of what you get with Clover Trail), but not faster than Intel's HD 4000 which we viewed as the minimum acceptable level of performance for processor graphics upon its introduction. However, if you're playing older titles, or when faced with more tablet-like 3D workloads, Kabini's GPU should do very well.
On the power front, Kabini is great. In our tests we found much better battery life than Brazos and even better battery life than 17W Ultrabook-class Ivy Bridge parts. The days of AMD being associated with poor battery life are long gone. Kabini manages compelling battery life and better performance than Brazos, which is exactly what AMD needs. Given how successful Brazos was (almost 50M units shipped), Kabini seems to have the right recipe.
The real question for me is what sort of laptops and devices well see when manufacturers release Kabini into the wild. The prototype laptop is really weak on some areas I care aboutthe keyboard and touchpad just dont impress, and build quality is flimsy at bestbut what it does have is a great LCD for what will hopefully be a budget-friendly laptop. Give me a reasonable Ultrabook-style chassis (or maybe a dockable tablet) with Kabini and a decent quality 1080p touchscreen and do it at the right price and there are plenty of people that will jump at the offer.
