Benchmark Antutu & 3DMark is low

seb

The performance of the Firefly-RK3399 with Android 7.1.1 (MP_170829) are almost identical than an ODROID XU4.
The announced performances are CPU +100% and GPU +50%
Why the performances are not reached at all ?

Running on Android 7.1.1 (MP_170829) and using OpenGL ES 2.0

It kind of sucks since this test  is devised for "low end smartphones"  and I chose the Firefly RK-3399 for its power to develop RV applications. I would have expected it to beat the top scores, given the hardware.
