Dear all,
First of all, as it is my first post, I’d like to say ‘hello’ to everyone in this group. And now, let’s get on with it!
I got my BBB black yesterday. As I’m a bit more familiar with Ubuntu than other Linux distributions, I downloaded an image of 13.04 here and decided to run some basic tests. To get some common ground for comparison with the raspi which I also own, I’ve decided to run the BYTEmark benchmark, as there’s publicly available results for standard and overclocked raspi. Here’s what the BBB scored:
BYTEmark* Native Mode Benchmark ver. 2 (10/95)
Index-split by Andrew D. Balsa (11/97)
Linux/Unix* port by Uwe F. Mayer (12/96,11/97)

What’s really puzzling me is the poor FP performance when compared to the Broadcom chip mounted on the pi. Any thoughts?
