Hello,


I have took a look at the following link about the performance
of the VISC architecture of Soft Machines...

http://www.bit-tech.net/news/hardware/2014/10/24/soft-machines-visc/1

Notice that they are saying that Soft Machines says that:

"The result, the team behind the technology claims, is a boost in 
instructions per cycle of 3-4 times compared to existing technologies 
resulting in a 2-4 times boost in performance per watt on both single- 
and multi-threaded applications.:"


Am i misunderstanding here? cause from what i know about parallel 
programming, that scalability is dependant also on the serial part
of the Amdahl equation, so in a "more" memory bound application it can
not scale to 2-4 times, so how can they say that in general there VISC 
architecture boosts performance by 2-4 times ? is it a marketing move ?




Thank you,
Amine Moulay Ramdane.
