cpu in ipad ....


There are some interesting highlights uncovered from this investigation:
HP Slate
The HP slate is a great example of what's wrong with the rest of the
industry. They believe that simply adding more features makes it a
better device - without considering the tradeoffs or how it will be
used.

In reality, HP slate starts at $549, iPad at $499 (Apple's price is lower
for a change).

HP Slate has a faster processor (1.6 GHz Atom vs. 1.0 GHz ARM), but
that's extremely misleading. iPhone OS is specifically designed to
eliminate unnecessary functions and is reportedly extremely fast on
the iPad. Windows Premium is going to run like a dog on 1 GB of RAM
with an Atom processor - particularly when you add the needed AV
software.

iPad is larger screen, better quality.

iPad has twice the battery life

iPad has faster networking.

iPad is lighter.

iPhone OS is optimized for multitouch. WIndows Home Premium is
going to be very clunky with touch.

The HP slate has more geek features - full Windows, more ports, etc.
But who cares? Anyone who needs all those ports and a full version of
Windows is not well served by EITHER of these devices.

If you simply need content consumption, the iPad is vastly superior -
for all of the above reasons. If you are into using your slate as a full
blown computer, you really need a full blown computer.

I can see only a tiny number of situations where the Slate wins out.
HP Slate:

+ $549 (aprox)
+ Atom Z530 processor. Optimized for embedded applications and in-order instruction execution.
+ Intel UMA graphic chip, with just 1080p optimization, but not real GPU.
+ Windows 7. An advanced OS with extensive use of .NET JIT Technology which, as any JIT, outputs non optimized out of order instructions. Also depends on a modern GPU, main reason most netbooks only have Windows 7 Starter. Interface is legacy keyboard and mouse system with a minimal API (Windows Touch) which appears to have a considerable lag maybe due to driver to API translation.

Apple iPad:

+ $499
+ A4. Part Cortex 8. Part PowerVR, SoC, with side by side RAM plane optimized for low power. No problem with instruction set or ordering.
+ GPU is part of SoC.
+ iPhone OS. Complete rewrite of Mac OS X system, optimized for small applications. All applications are cross compiled and optimized for the A4. Almost zero footprint for kernel and services. Almost instant touch response.

So in conclusion. The HP Slate is HP/Microsoft first attempt at emulating the iPhone (they had no idea what the iPad looked like), while the iPad is the logical heir to the iPhone/iPod touch legacy.
instead of trying to slam something that sells why not accept that what you need or want may not be the same as what someone else needs or wants.Apple tends to make products that just work very well for their intended use.If it fits the bill for what you need it will be trouble free -if you want something that does everything -but not one thing well ,then go for a microcrap based product.I think it is funny that the people who always want to slam apple will put so much energy into doing it.Why do you really care what other people want.Maybe you have wayyyyy too much time on your hands -or maybe it is just penis envy.BTW don't come near the urinal while I am there or your life will never be the sam
It's a no brainer. Maybe the Windows Phone 7 Series Slate Edition based on Silverlight (long horrendous Microsoft like name) might get any dent on the iPad. The problem's that that's coming until 2012, at the least. LOL!!! •The A4 package is composed of three layers: two layers of RAM (Samsung K4X1G323PE), and one layer containing the actual microprocessor.
•This Package-on-Package construction allows Apple to source the RAM from any manufacturer they want. While Apple is sourcing the RAM from Samsung now, this could be changed.
•The A4 processor is a single-core CPU, making it either an ARM Cortex A8 or a single-core variant of the A9. Most likely, it’s an A8.
•The two RAM layers each offer 128MB of memory, for a total of 256MB.
•The A4 is quite similar to the Samsung processor Apple uses in the iPhone. The primary focus of this design was minimizing power consumption and cost rather then developing a revolutionary new CPU.
•There are no markings on the CPU die, except on the Samsung DRAM
•Software benchmarks indicate that the A4 has the same PowerVR SGX 535 GPU as is present on the iPhone 3GS, but iFixit/Chipworks couldn’t verify this via hardware analysis. However, if the iPad’s graphics is powered by this GPU, graphics performance on the iPad is fairly poor relative to the screen size.
•Other manufacturer’s who supplied parts for the iPad include:
- Linear Technologies
- Intersil
- ST Micro
- NXP
- Cirrus Logic
- Texas Instruments
- Broadcom
