    From the anandtech article I would imagine the problem is just how different this new architecture is from everything before (on the AMD side at least). For at least this release, we need to have some patience.

    Anyone who's interested about this new architecture should check out the Anandtech article (not the benchmark one, the one previous to that). The article suggests that this is really the biggest architectural change at AMD since the R100 with the move away from VLIW to a more compute friendly design.
    Now, that is interesting for a few reasons.
    One, the OpenCL LLVM based compiler they released isn't too useful with the new design (but with the new design it seems as though the compiler becomes less important anyhow, so the compiler release was still a good thing).
    Two, and for me, the BIG ONE: hybrid video decode/encode. Apparently they've "copied" intel's ASIC for video decode/encode (though, it seems as though that was what UVD always was, but maybe UVD had more to do DRM?), but they're including a "hybrid" mode which offloads most of the work to the compute units (CU) and they leave some heavily serialised work to the UVD (again, I'm assuming DRM is included in that work). Thus is seems we might finally have some sort of video parity on the open source side with this new architecture (assuming, of course, they provide some help to driver developers to get the video decode/encode into a similar state as catalyst -- right now I can't imagine why they wouldn't as this doesn't seem like particularly valuable knowledge (ignoring any DRM/UVD issues), but perhaps Bridgeman can enlighten us?).

    Phoronix: AMD Radeon HD 7970 On Linux

    You've may have heard or seen that AMD introduced the Radeon HD 7970 graphics card this morning as their first product built in their "Southern Islands" family and is based on their new GPU architecture, but how well does it work under Linux for the open-source and closed-source AMD Catalyst Linux drivers?..
