The iPad 3 has 1GB of RAM

Chronic mentioned this on Twitter awhile ago already, but figured this was worth noting here as well.

It's been in plain sight since the beginning of February when BGR posted their exclusive photos of debug output from an iPad 3 development unit. The (full) last line says:

vm_page_bootstrap: 244276 free pages and 8396 wired pages

So, just do some simple math:

244,276 (pages) x 4,000 bytes (size of a page) = 977,104,000 bytes = 977MB


CORRECTIONchpwn pointed out to me that my "size of a page" above may be inaccurate, so here it is again, fixed:

244,276 (pages) x 4,096 bytes (size of a page) = 1,000,554,496 bytes = 1GB (rounded)
