Brother Zhou says he's going to overclock the big 2.7ghz core in the RG 556 to 3.0ghz (11% increase). Currently the t820 in the RG 556 benches a little better than the D900 in the RP4 in multi-core performance, and a little worse in single-core performance. I'm guessing this clock will bring it to bench a little better on both measures. The two will still more or less be on par.

On paper their GPUs are equivalent as well when it comes to floating point measures, but the AnTuTu score is noticeably (not astronomically) better for the D900. Not sure if that's down to other measures of the GPU, single-core performance, something else, or a combination of at least two of these factors.
