Introduction and Specifications
A couple of weeks back, we took a look at AMD's Llano mobile platform, with a mainstream notebook from Compal, and we came away impressed. If you're unfamiliar with Llano, be sure to check out our launch coverage (available here). But to quickly recap, Llano is the codename for AMD's latest Fusion-based product, that combines a CPU and GPU on a single piece of silicon. In the mobile space, Llano offers a capable quad-core CPU, with excellent DX11-class integrated graphics, in a very low power-envelope. Those things translate into good performance and solid battery life in a notebook, two highly desirable traits of mobile system.
AMD is now ready with Llano-based products for the desktop. On the desktop, Llano offers similar things. In fact, the underlying technology is identical. But the desktop landscape is very different from the mobile space. Desktops aren't constrained by the limited form-factors and thermal requirements of mobile systems, and as such, Llano has to compete with a much broader range of options and architectures.
AMD Llano Die Shot...
AMD thinks they have struck the right balance between CPU and GPU performance though, and at some very budget-friendly price points. Ultimately, consumers will decide if AMD is on target. In the meantime, we've got the first AMD Llano-based desktop APU, the A8-3850, in the lab, complete with a quartet of A75-chipset based motherboards. Pairing an A-Series APU and A-Series chipset results in what AMD is calling their "Lynx" platform. Cool codenames aside, there's lots of tech to discuss here, so take a gander at the features and specifications below and join as as we find out if Llano is as desirable on the desktop as it is in a notebook...
