A few days ago we pointed out that AMD was providing some choice media with some clues on how its upcoming Fusion-branded CPUs, based on Bobcat and Bulldozer, were faring in terms of performance per watt.
Unfortunately we weren't there to receive the info first-hand.
However, like the fawning father of a newborn child, AMD PR peeps were kind enough to point us in the right direction, so we can now break down the info that they have provided into something intelligible.
Apart from showing off physical samples of the Fusion CPUs, AMD has been discussing the power envelope of the new Fusion chips with the press at IFA 2010. Here's what has been discussed:
There are two initial Fusion SKUs, both targetting mobile and low-power desktop solutions. They should both be huge with corporate clients, and system integrators will love the form factors they will enable.
Zacate, the brawnier of the two SKUs, will be the dual-core, low-power version of Fusion APU, based on the Bobcat core, and will draw 18W. AMD is positioning this for the lighter notebook builds and some desktop and all-in-one use.
Ontario, contrary to popular belief, will be the single-core version of the same APU. Power consumption will be sliced in half, to just 9W, and will target the netbook and "device" market, something Intel has a firm grip on.
Despite the higher power draw (18W and 9W) compared to your standard Atom system, it's a bit of an apples vs pears comparison, as the GPU is now part of the CPU die and all the benefits and performance are already part of the formula.
The GPU element of Bobcat/Fusion will be enough to handle full HD decoding at 1080p, as well as DirectX 11 gaming, GPGPU and tweak your video quality through the Unified Video Decoder 3. For reference, the Fusion APU is about the size of a one Euro coin.
We expect to know a lot more about these designs very, very soon, so stay tuned.
