Four days after it began taking preorders, Apple has sold out of its initial supply of fourth-generation iPad units from its online store.
New orders for all models of the latest full-size 9.7-inch iPad are now advertised to ship in one week. That applies to all capacities ranging from 16 to 32 gigabytes, as well as both black and white colors.
Those who were among the first to buy the fourth-generation iPad will receive their units on its launch day, this Friday. Additional inventory is likely to be available at Apple's retail stores, for those who still seek a launch-day unit.
Apple surprised last week when it announced a new fourth-generation iPad with a faster A6X processor and the new, smaller Lightning connector. The new model completely replaces the third-generation iPad, which went on sale in March and brought the high-resolution Retina display to Apple's touchscreen tablet.
The fourth-generation iPad also adds a high-definition forward-facing FaceTime HD camera and is still compatible with the Smart Cover accessory. Like its predecessor, the iPad starts at $499 for a 16-gigabyte Wi-Fi-only model.
Benchmarks for the latest iPad have already started to leak out, showing the tablet's A6X processor more than doubles the composite Geekbench score of the third-generation iPad. The tests suggest that the A6X appears to be leveraging quad-core graphics, compared to the triple-core configuration seen in the iPhone 5.
Overall, the fourth-generation iPad achieved a Geekbench score of 1757, outperforming the iPhone 5 by ten percent and more than doubling the scores seen with the third-generation iPad and iPad 2.
