So to extend your logic, any non-x86 architecture that exists, is superior to x86? ;-)

Where do these numbers come from?

Based on what criteria are you claiming that ARM architecture is superior? Intel and ARM make different tradeoffs when designing their processor cores. Usually Intel is more aggressive with performance, while ARM is more aggressive on power efficiency.

Because of its PC-based business model, x86 processors are spellbound to binary compatibility. Intel have to design processors to be able to run binary code written for 2 or 3 generations before - not only just "able" but fast and efficiently, because PC users will evaluate new processor performance with older generation of benchmark code. I believe intel can produce highly optimized high-performance processor, perhaps even better than ARM guys, but pressure from their mainstream PC market will not easily allow to do so.

Intel has a better technology Steven, always one or two generation ahead. Intel has better marketing, much larger budget than any other processor makers. So why would ARM exists at all if it didn't have a better architecture? Kris

I don't know it is safe to say architecturally ARM is superior. Is there any fundmental architecture difference between ARM and other RISCs? The ISA doesn't matter. Basically business model counts.

thank you Sylvie...we would be interested in having a talk on Barcelona design at emerging technologies conference in Vancouver in 2012? www.cmoset.com, would you be interested by any chance? Kris

I am not sure I agree Mike...yes, the process technology has been always helping Intel, so will 22nm process...but architecturally ARM is superior...is it an open question who will prevail 2-3 years from now, right now Intel is increasing their market share and revenue growth is really impressive!

I'm siding with Intel on this one. They've been successful for over 40 years and they keep evolving and adapting. 22nm process technology is going to be a big winner with a lot less power and a much smaller chip size (cheaper). ARM will lose most of the power advantage they used to have and as technology continues to march towards 16nm, 10nm, etc, it'll no longer be a factor. It'll be about features, ease-of-use and performance

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
