iPhone 4S processor is 800Mhz, 73% faster than iPhone 4?

New tests conducted over at AnandTech reveal that Apple has chosen to underclock the A5 system-on-a-chip nestled inside the iPhone 4S to ~800MHz, just slightly slower than the iPad 2's 1GHz, but still far better than the iPhone 4's A4 SoC -- by margins as high as 73%.

iPhone 3GS won't be getting iOS 5 update? [Rumor] [Updated]

Apple TV has A4 chip, iOS, so where are the apps, games, a web browser?

The new Apple TV is running on an Apple A4 chip, just like iPhone and iPad, and almost certainly running iOS, so where are the apps, games, and web browser?

We got Netflix, but it was built in just like YouTube. We got iOS under the covers but no iOS-style UI. We got AirPlay, so we can stream from iPhone or iPad, and presumably there'll be an Apple Remote app to control Apple TV via iPhone or iPad...

... but I kinda wanted more.

More from iPhone 4 teardown - is Apple A4 1GHz?

We previously mentioned iFixit was tearing down the iPhone 4, and had confirmed 512MB of RAM and said the front and back displays were Corning Gorilla Glass. Well they're done with the teardown now and here are some more details.

The only area where we're still unclear is the Apple A4 system-on-chip. iFixit says 1GHz below but Engagdet thought that, while faster than iPhone 3GS, it was slower than the confirmed 1GHz iPad, and MacRumors rough benchmarks bear that out. So what's the deal on the chip? Is it doing more or did Apple clock it down to get that amazing battery life and lower the thermal impact?

More from iFixit after the break.

Everything you need to know about Apple's new iPhone 4

iPhone 4 is the most significant hardware revision to Apple's widescreen iPod, breakthrough internet communicator, and phone since the original iPhone 2G was released in 2007.

We'll take the most interesting of both and see just how important they are, after the break.

Apple buys chip designer Intrisity for $121 million

Apple has bought chip designer Intrisity for $121 million. Given the rapidity and speed of the Apple A4 chipset debuted alongside the iPad, rumors have persisted that Intrisity was behind the new system-on-chip (SoC), but confirmation took a while to arrive.

Intrisity was able to take the standard ARM Cortex A8 found in 650MHz flavor in the iPhone 3GS and competing smartphones and speed it up to 1GHz.

iPad A4 Chipset Uses PowerVR SGX Graphics Core

The iPhone 3.2 SDK for iPad has officially outs the PowerVR SGX as the graphics core inside Apple's A4 chipset:

Using OpenGL ES on iPad is identical to using OpenGL ES on other iPhone OS devices. An iPad is a PowerVR SGX device and supports the same basic capabilities as other SGX devices. However, because the processor, memory architecture, and screen dimensions are different for iPad, you should always test your code on an iPad device before shipping to ensure performance meets your requirements.

iPad A4 Chipset Cost Apple $1 Billion?

We typically don't run those stories about iPhone or iPad component costs anymore because they're just silly -- a couple of hundred dollars in metal parts per unit never takes into account R&D and marketing costs, and things like paying $1 billion for the new Apple A4 chipset in the iPad. Or so hints the New York Times:

Apple iPad A4 Chip Designed by PA Semi Team... or Not?

Venture Beat claims a "very trusted" source has informed them that Apple's PA Semi team might not have been behind the new iPad's Apple A4 chipset:

PA Semi didn’t do the A4. It was the existing VLSI team. Apple has made custom chips for years like the Northbridges for G4 and G5.
