Roughly 20 kn/s according the poster below.
Post was in August 2012, so sf_2.2.2 which has a CCRL of 3113 (SF10 is 3548), it was competitive with Anmon and SOS 5.1 on an i5-2405S CPU @ 2.50GHz. (Both engines can only use 1 core) Both are roughly 2550 CCRL elo (40/4).

Fritz 8 was beating top humans on a Centrino 1.7 ghz.

On passmark it has a single thread rating of 521, the i5 has a single thread rating of 1614.

So I'd wager Anmon and Sos on the i5 are roughly equal to Fritz 8 on a 2004 laptop.
So I think Magnus could win against SF 2.2 on the first Raspberry Pi.
SF10 and the latest dev version should smash every human ever, even with just 20 kn/s.
