Well, wildly might be slight exaggeration, but the discrepancy we encountered running Linpack for Android benchmark on two different RK2818 tablets was enough to cause a stir. To get you all up to speed, we’ve had the opportunity to play with a couple of ‘generic’ RK2818 7-inch Android 2.1 tablets and just see how they work/function etc. For the most part, the experience has been smooth and uneventful… except for one thing. Over time, we began to notice one of the tablets felt a touch slower than the other but we couldn’t really place it. It was hard to find differences in playback of 720p HD video. Browser scrolling speed is subjective and unreliable. So we decided to do a benchmark. The 3D benchmark variants of Quadrant and Neocore didn’t work at all, so we used Linpack. The results are telling… it seems one of the generics has significantly better Android implementation than the other, despite the exact same hardware. What could the difference be in the ROMS? Well, speculation is meaningless at this point so just take a look at the scores yourself, after the break. One implication to consider, though, is this: if you’re in the market for an RK2818 tablet, how do you know you aren’t getting the worse one, especially with all the generic no-names floating about? The answer is you don’t. Yet.
A 3 second difference to complete the benchmarks with roughly .4~.5 less MFLOPS, the lower pictured RK2818 unit scored significantly lower, confirming our suspicions of a slower tablet. It ‘felt’ slower, but we couldn’t quantify it by eye like you can between, say a MIDnite and an aPAD. But the synthetic benchmark helped us to quantify that difference.
Note: All processes were killed using Advanced Task Killer prior to running the benchmarks. Both units are powered by RK2818 Rockchip SOC, with 256MB DDR2 RAM. Both run Android 2.1.
