I've been comparing RK3066 and RK3188 mini PC Linux performance. I use them mainly as headless servers (I'm not concerned with GPU performance here). I used UnixBench for the benchmarks on non-modified hardware. Both mini PCs have the same class 10 microSDHC, so IO would be comparable. I set the maximum CPU frequency to 1.2 GHz since you will have over heating problems going higher without cooling modifications. I built a Ubuntu 14.04 distribution with just the basics and booted from SD card. It will interesting to see what the RK32xx will do when it's released this summer.
If you want to share you scores (different CPU frequencies, running Linux from NAND or USB HD) post the scores here.
To give you some perspective:
RK3066 (MK808), 2 cores, 1.2 GHz, olegk0's 3.0.8+ kernel, Ubuntu 14.04:
RK3188 (MK802IV), 4 cores, 1.2 GHz, Alok's 3.0.36+ kernel, Ubuntu 14.04:
If you want to share you scores (different CPU frequencies, running Linux from NAND or USB HD) post the scores here.
To give you some perspective:
| Hardware | Score |
| Raspberry Pi (1 core @ 700MHz ARM) | 109.8 |
| MK808 (2 cores @ 1.2 GHz ARM) | 352.5 |
| AMD Sempron Processor 3400+ (1 core @ 2 GHz x86) | 555.1 |
| MK802IV (4 cores @ 1.2 GHz ARM) | 617.7 |
| Odroid-U2 (4 cores @ 1.7 GHz ARM) | 806.6 |
