About tablet and Intel vs ARM
Tablet Market Share Q2 2012
Rumored Apple TV might be good for headline news, but tablet will be force driving growth in next couple of years. Apple intend to gain as much market as possible and try to do what Microsoft Windows did to PC world with ecosystem lock down. That's why Apple updated every single iOS devices before the holiday season.
This market will get even more interesting with entrant of Microsoft surface. Surface with an Intel chip means you can run any PC applications on it.
Don't underestimate Microsoft and Intel. The main advantage of Arm chips is power, but Intel is closing the gap with die shrink to 22nm. Arm chips might still have an advantage in power consumption, but in terms of processing power, Intel chip is far superior. IF Intel can successfully shrink the die to 14nm in 2014 and drastically improve power consumption..... Arm chips will have even less power advantage and Intel could dominate mobile market of Android. What made mobile chip market less attractive is lower profit margin, mobile chips are simpler and lower priced. However with the shift to mobile, Intel have to compete in this market.
This is not an easy choice to make!
1)Intel's making money in PC market
2)mobile market is taking market share from PC
3)chips in PC have higher profit margin than chips for smartphones
This is why Kodak invented the first digital camera but hesitated to push it. Because Kodak makes money selling films for cameras with high profit margin, pushing digital camera will kill it's old market and digital camera doesn't need films! Where is Kodak now? (bankrupt... -_-!)
This explains why Intel was slow to push it's mobile chip.
OK...Intel's position is similar but not nearly as bad as Kodak because CPU market have a very high entrance barrier and Intel is accelerating mobile development by spending 9.8 billion in R&D in last twelve months.
Intel Atom roadmap
Q2, 2012 Medfield(Saltwell core) (32nm)
Q4, 2012 Clover Trail (Saltwell core) (32nm)
2013 Silvermont (22nm)
2014 Airmont (14nm)
Apple Ax
2010 Apple A4(using ARM Cortex-A8) (45nm)
2011 Apple A5(using ARM Cortex-A9) (45nm)
2012 Apple A5X(using ARM Cortex-A9) (45nm)
2012 new Apple A5(using ARM Cortex-A9) (32nm) (achieved better power consumption due to die shrink)
2012 Apple A6, custom Apple designed (32nm)
2012 Apple A6X, custom Apple designed (32nm)
There's no question that Apple wants Control. It's clear with their A6, the first fully customized chip by Apple. Here's an interesting story about the decision back in 2005:
Since Apple decided to transit to Intel's x86 chips in 2005, Mr. Jobs planned to use low-power Intel Atom microprocessor inside the iPad initially. However, Tony Fadell, the senior vice president of the iPod division at Apple, insisted that the iPad would be ARM-powered although Mr. Jobs insisted that it was "best to trust Intel to make good mobile chips". The history knows what happened next: Apple bought PA Semi chip designer, which created the A4 system-on-chip for the company. Apparently, Steve Jobs was pretty pleased with the result and even told his biographer that Intel was anyway too slow and not too flexible to offer something comparable.
"At the high-performance end, Intel is the best. They build the fastest chip, if you don't care about the power and cost. But they build just the processor on one chip, so it takes a lot of other parts. Our A4 has the processor and the graphics, mobile operating system, and memory control all in one chip. We tried to help Intel, but they do not listen much. We have been telling them for years that their graphics suck. Every quarter we schedule a meeting with me and our top three guys and Paul Otellini. At the beginning, we were doing wonderful things together. They wanted this big joint project to do chips for future iPhones. There were two reasons we did not go with them. One was that they are just really slow. They are like a steamship, not very flexible. We are used to going pretty fast. Second is that we just did not want to teach them everything, which they could go and sell to our competitors," Steve Jobs told his biographer.
Meanwhile, Intel's chief exec Paul Otellini said that Apple and Intel could not agree on the price and on who would control the development. Apparently, Mr. Jobs demanded too much control over design of the x86 iPad chip. |
