iPad Air 2 Benchmark Points to A8X Chip With Triple-Core 1.5 GHz CPU, 2 GB RAM
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.
