Well, I can be short about this one. Anandtech did some nice coverage on it, as usual. The focus is entirely on the GPUs, which makes sense, since that is the biggest improvement in Richland anyway, and GPUs is where the battle is with Intel.
Namely, Richland is not an entirely new architecture, but merely an update of Trinity, reducing power consumption somewhat, and increasing clockspeeds. It also officially supports DDR3 memory up to 2133 MHz now, where Trinity only went up to 1866 MHz. This gives the GPU a bit more room to breathe in bandwidth-heavy scenarios.
One thing to note in the comparison is that Anandtech only used the desktop Haswells here, with a HD4600 iGPU. These are considerably slower than the Iris Pro 5200 iGPU in the previous Haswell iGPU article (which are only available in mobile parts, at least for now). The 5200 has the special 128 MB of high-speed EDRAM memory (‘Crystalwell’), the 4600 does not. And unlike the 5200, the 4600 can not quite keep up with AMD’s APUs yet.
As I said earlier though, both in my Trinity and Haswell articles, AMD will have trouble scaling up GPU performance. And Anandtech’s charts show exactly that. The difference between the 5800 and the 6800 is negligible. In fact, in one instance the 6800 is even slightly slower:
Richland and Trinity are THAT close. I couldn’t have asked for a better demonstration of my claims that AMD will have trouble scaling GPU performance in real-life applications.
At any rate, since Intel is keeping Iris Pro limited to mobile parts for now, AMD can still hold on to their GPU advantage on the desktop. Sadly Richland has not really managed to widen that advantage.
