On the smaller Geekbench (no comment, the aim is to look at a smaller bench :-), J1900 vs 5350: http://browser.primatelabs.com/geekbench3/compare/513198?baseline=514388
As David expected, the FP score is significantly higher despite the frequency deficit.
In Anand review, the 3DPM result is an outlier. A quick disassembly shows it's using x87... I guess Ian Cutress should recompile it with better flags :-)
