Microsoft has had a few tries at the “Remote Desktop” system over the years, with Terminal Server and Remote Desktop being the two most notable.  They’re coming out with the next iteration in this, in combination with Citrix systems, called RemoteFX.  AMD, in particular, seems excited about this, in particular with this one point:

And the Microsoft RemoteFX feature will accomplish this by harnessing the power of GPU computing to accelerate the rendering of hosted desktop PCs when paired with servers running Windows Server 2008 R2 SP1, such as servers based on AMD Opteron™ processors.

GPU acceleration is cropping up everywhere these days, and being able to push “rich 3D, multimedia experiences” remotely would be huge.  AMD has been working with Microsoft on some time by providing server hardware and testing platforms, and combined with this new “HDX” technology it could be a big win for AMD.
