I don't know of any hardware that natively compresses. I think Nvidia
has a whitepaper on their site about accelerating the compression with
more recent GPUs, but you have to code it yourself.

Which isn't even necessarily true. Some hardware vendors got a
sublicense from Microsoft that allows them to expose the functionality
in D3D *only*.
