The R-Pi Ethernet is 10/100, and the B-Pi Ethernet is 10/100/1000, so the B-Pi will always win this hands down. This is a given.
Even with both connected to a 100 Mb hub, the rPI will be worst, by design ... due to the fact both USB and Ethernet are sharing the same channel. The A20 has different channels for that, so far better performances.
So note - the R-Pi is 700MHz, and the R-Pi2 is 900MHz while the B-Pi is 1GHz.
By default, bPI don't go above 900 Mhz : faster clock are deactivated in LeMaker's fex file.
That does not mean a thing unless you are using software that takes advantage of that, if not most of the major processing it done by 1 CPU while the others sit and wait
It's true on non multitasking environment like Arduino or PICs : on bPI and such, you have a plain OS so tasks are dispatched on available cores. In addition, you have some of the tests above that are multi-treads (clearly indicated in the report) and in such situations, rPI is obviously faster than bPI.
SATA Drive test? Of course the B-Pi will win because the R-Pi does not have that.
rPI2 has 4 cores, bPI only 2 / rPI doesn't have SATA, bPI has. The choice is mostly here.
The R-Pi does have its place.
Clear Now, I take also in account the Raspberry foundation and clearly, I don't like a company that claiming everywhere they have rights on others' work without never provided any proof (and it's annoying some 3rd parties like sourceforge follow them w/o arguing, w/o thinking) ... But it's only personal reasons
