According to this Engadget comparison (http://www.engadget.com/2011/02/09/hp-touchpad-vs-ipad-vs-xoom-vs-playbook-the-tale-of-the-tape/ http://www.engadget.com/2011/02/09/hp-touchpad-vs-ipad-vs-xo...), competing tablets (TouchPad, Xoom, PlayBook) all have 1GB of RAM. It wouldn't be surprising for the 2nd iPad to have 1GB or more RAM.
- moe 16y agoAnyone know why they're skimping on the RAM? Does the ipad need some super-special expensive DIMMs? Is it about power consumption? A 4GB DDR3 SO-DIMM costs a measly $40 bucks. I don't think the ipad target audience would care if apple added that to the MSRP.
- msbarnett 16y agoIt's almost certainly about power consumption; Apple absolutely loves being able to tout huge battery life compared to the competition, and one way they do that i s by being tighter on things like RAM usage. It's also worth pointing out that the RAM lives in a Package-on-Package configuration right on the CPU die. They're not exactly buying mass market SO-DIMMs and sticking them in a bog-standard bus, so the cost per MB is probably higher.
- wiredfool 16y agoThe processor and the ram are stacked on the same chip. So they're kinda limited as to what they can put in there. I doubt that you could fit a SO-DIMM of any stripe inside an ipad case, nor would you want the power problems. There was a teardown of the chip assembly done back when the ipad came out that has some good details: http://www.ifixit.com/Teardown/Apple-A4-Teardown/2204/1 http://www.ifixit.com/Teardown/Apple-A4-Teardown/2204/1
