Performance Numbers Leaked on AMD's Ontario

Add Your Comments

The German website (Google translation) has scraped some performance numbers from the BOINC database on AMD’s upcoming Ontario accelerated processing unit (APU).  The Bobcat architecture is most closely comparable to Intel’s Atom, where the name of the game is low power.  As such, the numbers aren’t anything mind-blowing, but it does beat the Atom D10 processor in floating point speed and integer speed.  Using two other AMD CPU’s, the guys at deduced that the Ontario is probably clocked at 1.4 or 1.6 GHz.  Another interesting note is that the Ontario reports an odd 488 KB of cache while the Atom D10 has 512 KB.  I’d suspect that this is just a glitch since it is an engineering sample.
