As usual with product releases from Apple, numerous online sources compete to show detailed teardowns of the devices when they are available. Not only do people test the physical durability (even going so far as to blend the original iPhone), but they also benchmark the devices to see if they live up to the advertised specifications. With the iPad, however, some folks have gone one step further to bring a full teardown of the custom A4 chip.… Read more
As the Apple iPad and its A4 chip get ready to ship on April 3, the competition is not standing still--and, by all appearances, there's plenty of it.
As reported back in January, the A4's central processing unit, or CPU, design, as it stands now, is thought to be based primarily on technology from U.K.-based ARM. Linley Gwennap, who is the president and principal analyst of The Linley Group, believes the A4 uses a fairly common ARM CPU designed by Intrinsity and manufactured by Samsung.
Where Apple, instead, may have chosen to enhance the A4's … Read more
Along with the iPad, the Apple chip has arrived.
Called the A4, ("A" presumably for Apple), the most obvious difference with the chip in the iPhone 3GS is speed. The iPad's chip runs at 1GHz, compared to the estimated 600MHz (0.6GHz) of the iPhone 3GS. On Wednesday, at the event in San Francisco, the A4 was billed as "the most advanced chip" Apple has done yet. While fast, it's also frugal with power. "The A4 chip is so power efficient that it helps iPad get up to 10 hours of battery life,&… Read more
I was recently handed the keys to a fully loaded, brand-new Audi S4 sedan. So, I did what any motorhead would do in this situation and proceeded to put the sporty A4 variant through its paces on the open road, on an autocross cone course, and even on the track at Infineon Raceway at Sears Point.
Our adventure starts with a trip from an uncharacteristically sunny San Francisco across the Golden Gate Bridge and into Sonoma. While in the stop-and-go bustle of the city, the S-Tronic DSG double-clutch automated manual was so docile and the 3.0-liter supercharged V-6 engine … Read more
Senior Editor Wayne Cunningham reported earlier on Audi's A4 iPhone app and found that instead of being an innovative way to interface with your vehicle via iPhone, it was merely a game designed to market the newly updated A4 sedan. Recently, Audi updated the app with two new unlockable vehicles and some tweaks to the controls. Having recently purchased an iPod Touch, I decided to take Audi's app for a spin.
The Audi A4 Driving Challenge 2.0, which is a free download from the iTunes App Store, is played by holding the iPhone in landscape orientation. Thumbs … Read more
Audi's big news from this year's Geneva auto show is the release of its updated A4 Avant. The all-wheel drive wagon is six inches longer than its predecessor, giving it more than 50 cubic feet of storage space. The Avant comes with a choice of two direct-injection gasoline and three diesel engines: the top-of-the-range V-6 is good for 265 horsepower. The Avant is based on the same layout as the updated A4 sedan that we saw in Frankfurt last year, and features the same suspension configuration and the same Audi drive select system, which lets drivers influence how … Read more
Audi has released photos and some spec info on its new A4, which will officially debut at the 2008 Frankfurt auto show in September.
Most notable to tech enthusiasts may be the optional xenon headlights that include 14 LED lights. These are "daytime driving lights," aka LED bling, for your car. Audi refers to them as "wings." I think they look more like eyelashes. You can see what they look liked turned on below.
