While Apple touted the power of the new A8X chip used in the iPad Air 2 at the company's media event last week, the company as usual opted not to disclose exact specifications on the part, leaving the details up to rumor and speculation until the device starts making its way into the hands of users and teardown experts.

But with Apple shipping out orders to customers for delivery as soon as tomorrow, it appears that at least one user has already gotten his or her hands on the iPad Air 2 and run a Geekbench 3 benchmarking test on it (via Gizmobic). If the result is genuine, and Primate Labs founder John Poole tells MacRumors that it appears to be, it reveals that the A8X contains an unusual triple-core CPU configuration running at 1.5 GHz and paired with 2 GB of RAM.

The extra core and 100 MHz faster clock speed compared to the A8 found in the iPhone 6 and 6 Plus means the iPad Air 2 scores roughly 13 percent higher on single-core benchmarks and 55 percent higher on multi-core benchmarks than Apple's latest iPhones.

More details will undoubtedly be unveiled in the coming days as teardown experts take the iPad Air 2 apart and chip experts examine the internal layout of the chip.

Odd core numbers are pretty much non-existent in ARM-world, so this is interesting to see. Triple core also helps explain how they got to 3B transistors. Too bad geekbench doesn't accurately report that "L3" cache.

Well, didn't they say it had 3 billion transistors?

And they also said the iPhone 6 had 2 billion transistors.

No comparison to the existing iPad Air? I guess I'll go do my own research...

EDIT: So it looks like iPad Air was at 1467 single core and 2656 multicore. So decently better on single core performance, but nearly double multicore.

Not that odd when you consider Apple has been designing their own chips for years now.

Sure, they may start with ARM architecture....but Apple HEAVILY modifies these essentially creating their own chips.

Which is why they've been so successful making powerful, efficient chips for so long.

This is a gnarly benchmark.
