I don't have an XR2 devkit so I can only guess, but TDP-wise they seem pretty comparable. Obviously that doesn't include boost power etc and there's stuff integrated into the XR2 that we need to do on an FPGA, but overall I've not felt like a modern x86 processor is overly disadvantaged.

I'm sure one could do a more rigorous comparison, but IMO with the recent Intel/AMD chips you get pretty good performance/power.
