The first Fusion processor is code-named Shrike, which will, if our sources are right, consist of a dual-core Phenom CPU and an ATI RV800 GPU core. This news is actually a big surprise, as Shrike was originally rumored to debut as a combination of a dual-core Kuma CPU and a RV710-based graphics unit. A few more quarters of development time gave AMD time to continue working on a low-end RV800-based core to be integrated with Fusion. RV800 chips will be DirectX 10.1 compliant and are expected to deliver a bit more than just a 55 nm-40 nm dieshrink.

While Shrike will debut as a 40 nm chip, the processor is scheduled to transition to 32 nm at the beginning of 2010 - not much later than Intel will introduce 32 nm - and serve as a stop-gap before the next-gen CPU core, code-named "Bulldozer" arrives. The Bulldozer-based chip, code-named “Falcon”, will debut with TSMC’s 32nm SOI process, instead of the originally planned 45 nm.

As Fusion is shaping up right, we should expect the chip be become the first half-node CPU (between 45 and 32 nm) in a very long time.
