hey...
I'd appreciate if someone can advise on the hardware aspect of mobile phones.. In particular the mobile chipset - it's specifications, speed, etc.
How do mobile phone CPUs differ from my pc's CPU? How does a 32-bit Intel XScale® core-based CPU running at 400 MHz (used in mobile/cellular devices) compare to a 32-bit Pentium 3 running at 450 Mhz on my PC?
Simply put, does there exist common ground to compare the two class of CPUs?
Can any1 help?

Heard 6600 has a 106 mhz processor...that does put things into perspective...However, I was wondering about the peripheral synergies that come together to drive the speed in a pc such as ram, fsb, etc...Is that present too in the mobile architecture?
I guess my question is still unanswered: Does 106 mgz in a mobile handset == 106 mhz in a pc?
Well,
the faster the components of a computer (RAM, etc) the faster the computer will run.
In other words if you have a computer at 2.4 GHz and you have like old SDram that is slow and you have an old hardrive at 10 GB and 3200 RPM that will slow the whole system down even if you have a fast computer. So basically the phone at 106 MHz can run faster than the pc if the pc has really slow outdated technology.
Hope this helps!
To take a page from AMD's book, the actual clock speed of a 400MHz processor is 400MHz, no matter what kind of processor it is. Just like going 40 miles per hr is the same if you drive a Ferarri or a Metro. If a processor can do more work (ie. work more efficiently) during each cycle, then the amount of work done will vary, which is the reason AMD uses their model numbers. The actual clock speed is lower than a comparable P4, but it is more efficient. The processors used in phones and PDAs may have the 400MHz clock speed, but if they had the pipelines that even a Pentium II had, it would run way too hot and use too much power to be useful in a handheld device. These processors also lack the expensive cache (L1 & L2) that desktop processors have that improve efficiency.
Memory constraints are also an issue...mobile phones and PDAs use "flash" memory, which currently isn't as fast as the RAM in your computer. If you've used a digital camera, you have seen that it takes a few seconds for them to write the pictures to the memory cards, so there is a bit of a bottleneck there as well.
I suppose the moral is that I would think they are too different to really compare...
Hope that answers your question,

Well think of the size the processor is deff bigger in the computer but the speeds are the same
