Hi!

I've udpated the Android NBench with Amd v7 optimizations.

The Android results should be much better now (esp. float) :)

And note that nbench is a single core benchmark.

Also you'll find lots of results here: tux.org /~mayer/linux/results2.html

BR,

For example on my old Droid 1 (OMAP @800Mhz), with the new benchmark, I get:

MEMORY INDEX : 3.104

INTEGER INDEX : 3.618

FLOATING-POINT INDEX: 1.396

BYTEmark* Native Mode Benchmark ver. 2 (10/95)

And on my Xperia pro (Snapdragon @1GHz):

MEMORY INDEX : 3.383

INTEGER INDEX : 4.786

FLOATING-POINT INDEX: 4.194

So the Snapdragon is much faster than the OMAP for floating point operations, which is good for 3d games :)
