Not all that impressive since those are both single-threaded benchmarks where a 4 GHz (with turbo-boost on a single core) Kaveri is... somewhat ahead of Piledriver. The trick is, AMD's roadmaps have shown that four coars is it for Steamroller. There's no replacement for the FX-8350.. it literally doesn't exist. It's APUs only until at least 2016 (and that's only because AMD hasn't put out any roadmaps into 2016, not because there are known plans for 8/16/etc. core chips). That's fine if you want to use the IGP, which is strong even under Linux with the less than perfect Catalyst driver, but the 4-core version can't keep up in the multithreaded tests with a real quad-core chip or a 6 or 8 core FX part.
No announcement yet.
