[ITProPortal] ARM vs x86 : How 2012 Is An Inflexion Point For Intel - Page 3

Intel's x86 CPU have provided more and more performance over the years even though clockspeed has not increased that much. Intel and AMD add additional features to improve performance but use more transistors which means more power consumption.
For example, higher performing CPUs do Out-of-Order Execution. They figure the order of instructions to optimize data access and CPU usage instead of doing things as requested. This feature takes extra circuits to figure out the optimal path.
Another related example it path prediction where the CPU "guesses" the results. If the guessed path turns out to be correct, there is a significant time saved. If the path misses, you pay a slight penalty. Intel's path prediction algorithms are probably the best in the world. However, these again require more circuits.

Then I guess the only advantage of ARM is that anyone can get a licence, which would make the desktop market much more interesting. I hope ARM catches up soon.

It seems like they were being more conservative initially opposed to going 'all-out' on a design.

I hardly doubt that with the right resources they'd have been able to accomplish everything they have up until now a lot sooner.

 

If that's the case then I'm not the least bit impressed by 2-3x performance.

Yes, but they are achieving their performance by hitting the lowest hanging fruit features.... Intel and AMD have already utilized and popularized these many of concepts over a decade ago.


As you try to extract more performance per clock, you will begin to hit walls in what you can do + power consumption + transistor budgets.

AMD and Intel will have tablet and phone parts ready in 1-3 years, and ARM will be in Windows 8 desktops and laptops in 1-3 years. It is going to be a freekin mess.

X86 can emulate ARM code right? Because if so, but ARM cannot emulate X86, then I see problems for ARM's future, and now X86.


Power consumption is absolutely NOT going to matter in the future as battery technology gives us 10 times the charge per cell. I wonder how this will effect ARM vs X86?

Emulation is software representation of hardware. There is very high overhead costs in performance.


What battery technology do you speak of? Batteries will never become small enough and heat dissipation would still be an issue.

Intel is working on creating their own SOC (System On a Chip), we have seen that in their new Server Processors, Ivy Bridge, and their future CPUs will continue to expand upon power efficiency and reduce the size of the CPU. Eventually Intel will have a mobile processors that will be 2nd to none, all they have to do is reduce power consumption (which they are already working on hard), reduce Cost / Price, and last but not least, they must also improve their graphics / IGP to the point that it's plays back flawlessly at 1080p HD...

I'd give Intel another 2 years and they will have the leading best CPU in ALL markets...

ARM may be winning in the mobile markets for now, but Apple would be a fool to switch their Macbooks to ARM instead of Intel's Core i Series of CPUs, besides, Intel would in turn respond by being ultra competitive with Apple, by helping Apple's competitors develop a much better product...

The moment Apple goes cheap, their clients are going to get very upset, Apple is known for innovation and using some of the best technology on the market, it they change that trend, it will come back to bite them hard...

Just my 2 cents..

The real problem is Microsoft is trying to follow Apple, and that scares me..

The tech has already been proved to reach 1000% longer charge and 1000% lower charge time. Battery tech is heavily researched, and over the next few years battery life will only be a problem for long term GRID storage.
