The story originates from German site Hardware Infos which seems to have gotten its hands on a leaked specification table that shows the Ontario based accelerated processing unit (APU) to be capable of 1,352 GFLOPS of floating-point performance. To put this in context this is just over twice the performance of an Intel Atom D510 CPU, but falls 15 per cent short of a low power Athlon II X2 250u. The leaked performance figures also suggest the APU contains a curious 488kB of cache.
While it’s disappointing that AMD’s new architecture seems to be beaten out by a processor based on the ageing K10 architecture its worth remembering that Ontario based APU’s are reported to operate at only 18W and include a DirectX 11 graphics core to boot. This compares favorably to the 25W Athlon II X2 250u draws (which, don’t forget, will also require an additional graphics chip) and certainly points to Fusion being able to take the fight to Intel in terms of performance per Watt.
