Apple's A5 CPU in iPad 2 has 512MB of RAM, same as iPhone 4 - report


Though Apple has not officially disclosed how much RAM is found in the iPad 2, a Korean semiconductor analyst has claimed to know that the new A5 processor has 512MB of memory.

Responding to a query about the amount of RAM in the iPad 2, analyst Kakeun Lee claimed on Twitter (via Google Translate) that the new iPad will double the amount of RAM in last year's model. He also revealed that the new A5 processor features LPDDR2 memory, which is a speed boost from the LPDDR1 RAM in the first-generation iPad.

If true, the inclusion of 512MB of RAM confirms reports that the iPad 2 would pack the same amount of memory as the iPhone 4. Analyst Ming-Chi Kuo of Concord Securities also told AppleInsider that the RAM in the iPad 2 would run at a higher clock speed of 1,066MHz for greater memory bandwidth than the 800MHz memory in the iPhone 4.

Kuo also indicated back in January that the iPad 2 would have LPDDR2 RAM at a speed of 1,066MHz, corroborating Lee's more recent claims. Kuo said the memory would be supplied by both Samsung and Hynix.

512MB of RAM would be equal to the amount found in the iPhone 4, released last June. The amount of RAM supposedly in the new iPad is also half of the 1GB found in the Android-powered Motorola Xoom.

Apple prefers to avoid detailing technical specifications of its devices, instead focusing on features and usability. But the company did reveal on Wednesday that the new A5 processor is a custom-designed 1GHz dual-core chip with the same low power consumption as last year's A4.

The report also contradicts what a representative in London demoing the iPad 2 reportedly told Gizmodo: that the new iPad has the same 256MB of RAM as last year's model. However, the site was then told by another public relations person that they couldn't confirm how much RAM is in the new A5 processor.
