Now that's fast. Engadget just reported that according to a leaked copy of the iPhone's firmware, the device is running an ARM1176JZF processor running at around 620 Mhz. That's fast - one of the fastest we've ever seen in a handheld.
Meanwhile, in Semicondictor Insight's YouTube teardown of the iPhone, they mention that it's using a Samsung application processor with a separate baseband processor made by Infineon. Head over to Samsung's site, and you'll find they have one ARM1176JZF application processor: the S3C6400.
The S3C6400 runs at a blazing 667 Mhz, the fastest we've ever seen on a consumer handheld (high-end Intel-based handhelds previously were 624 Mhz) though Marvell and Qualcomm have both announced faster chips for the future. Some other features:
ARM1176JZF-S based CPU Subsystem with Java acceleration Engine
One 8-bit ITU 601/656 Camera Interface of up to 4M pixel for scaled and 16M pixel for un-scaled resolution - pity the iPhone stayed at 2MP
Multi Format CODEC (MFC) provides encoding and decoding of MPEG-4/H.263/H.264 up to 30fps@SD, and decoding of VC1 video up to 30fps@SD
2D Graphics Acceleration with BitBlt and Rotation - okay, so where are the games?
AC-97 audio codec interface and PCM serial audio interface
1/2/4/8 bpp Palletized or 16/24bpp Non-Palletized Color-TFT support up to 1024x1024
High Speed-MMC/SD card support (interesting)
Mobile DDR MemoryInterface with x16 or x32 data bus (266Mbps/pin DDR)

nice find I was looking through the 694-5259-38.dmg image in a Hex editor from the Iphone Frimware restore and found this exact line "decoding of VC1 video up to 30fps@SD" that seems to corrospond with your suspecion that the Samsung chip is indeed the S3C6400 just a thought PS great work! :) [IMG]http://www.uploadhut.com/upload/555719.png??[/IMG]

The processor in my first Mac ran at 400 MHz. That was 7 years ago. Man.

Not so. Many handhelds run at around those speeds and have done so for quite a while. In fact, they're throttling back, in order to save on the battery.

Does the clockspeed actually tell anything about the speed? Didn't Apple - during the times when they still used PowerPC CPUs and tried to fight against the Intel community - that clock speed did not really matter when talking about true speed of the processor? Following that reasoning, the 624 MHz information does not help when you would like to compare say the iPhone computing power against that of the Playstation Portable. Right?
