AMD Fusion is a new approach to processor design and software development, delivering powerful CPU and GPU capabilities for HD, 3D and data-intensive workloads in a single-die processor called an APU. APUs combine high-performance serial and parallel processing cores with other special-purpose hardware accelerators, enabling breakthroughs in visual computing, security, performance-per-watt and device form factor. Software developers, utilizing AMD drivers, libraries and either the ATI Stream SDK2 or the Microsoft DirectCompute API, can enhance the user experience and speed application performance by developing applications that fully utilize the unique compute power of the AMD Fusion™ Family of APUs and AMD discrete GPUs.
APU designs enable an amazing experience in any form factor, and are designed to provide significant advantages in power and design simplicity over competing multi-chip solutions.

Zacate is AMD’s 18W APU aimed at the mainstream notebook market (~$500 notebooks). The APU features a pair of Bobcat cores and a Cedar-class AMD DX11 GPU. Zacate package has a single 64-bit DDR3 memory interface ala Atom. Unlike Atom however, both the Bobcat cores and the DX11 GPU should be relatively high performance.
AMD views Fusion targets not only bring better gaming performance to the market, but also enable a lot of new GPU compute applications. With this type of GPU compute in the entry level, it’s only a matter of time before developers start to do something with it.
The Zacate GPU performance we’re seeing here today is completely unoptimized as well. The clocks aren’t final, drivers aren’t fine tuned and although we’re close to release, there’s still potentially more performance on the table.
AMD Zacate will make note-book market again interesting and full of challanges.
