More Cores vs Higher Clock Speed For Mobile Devices

We've seen multi-core chips powering desktops and laptops for a number of years but are now starting to find vendors putting the technology into mobile devices. In this video, I raise the question as to whether this route is the best vs having a CPU of higher clock speed on a single core.

--continued-- We can make single core chips with more performance per clock, but in the age where intel can put 700m transistors on a die, it becomes harder to push serial instruction performance with one core. The logical choice is to make multicore processors. There is no choice between single core and multicore. We have pushed single core as far as it can be pushed (at moore's law rates anyway, slower advances allow it to edge up as well)

@cartossin Interesting. I knew there had to be a good reason why all the big manufacturers were pushing dual-core chips but it's good to have some idea about what that reason is.

As processors advance, one thing has remained constant. Transistor count goes up. A core2duo (conroe) is not faster than a prescott pentium 4 simply because it has 2 cores. Each core is considerably faster per clock. Clock rate has basically stopped going up. Over the next 10 years, we might see consumer chips to to 6ghz (as very high end powerpcs are there now), but this will not be where the performance comes from. --continued

Great video man!

@MrAKJx2 This is why Google just blocked your domain extension. ;)

It really depends how well programs are multithreaded. Programs dont really run faster on dual cores if they arent multithreaded properly or all.
