A Reference Platform - But not a great one
Believe it or not, AMD claims that the Brazos platform, along with the "Brazos 2.0" update the following year, were the company's most successful mobile platforms in terms of sales and design wins. When it first took the scene in late 2010, it was going head to head against the likes of Intel's Atom processor and the combination of Atom + NVIDIA ION and winning. It was sold in mini-ITX motherboard form factors as well as small clamshell notebooks (gasp, dare we say...NETBOOKS?) and though it might not have gotten the universal attention it deserved, it was a great part.
With Kabini (and Temash as well), AMD is making another attempt to pull in some marketshare in the low power, low cost mobile markets. I have already gone over the details of the mobile platforms that AMD is calling Elite Mobility (Temash) and Mainstream (Kabini) in a previous article that launched today.
This article will quickly focus on the real-world performance of the Kabini platform as demonstrated by a reference laptop I received while visiting AMD in Toronto a few weeks ago. While this design isn't going to be available in retail (and I am somewhat thankful based on the build quality) the key is to look at the performance and power efficiency of the platform itself, not the specific implementation.
Kabini Architecture Overview
The building blocks of Kabini are four Jaguar x86 cores and 128 Radeon cores colleted in a pair of Compute Units - similar in many ways to the CUs found in the Radeon HD 7000 series discrete GPUs. Josh has written a very good article that focuses on the completely new architecture that is Jaguar and compared it to other processors including AMD's previous core used in Brazos, the Bobcat core.
