As part of their iPhone 5 announcement, Apple revealed that the new iPhone is powered by a new "A6" processor from Apple. The A6 is said to have twice the CPU power and twice the GPU power of the previous generation Apple A5 processor. Beyond that, however, Apple offered few other details about the nature of the processor. For example, it's not clear how many cores the processor has or what the clock speed is.
Early speculation had led some to conclude that that the A6 was based on the yet-to-be-seen Cortex A15 ARM processor design. The Cortex A15 is licensable processor design from ARM that promises significantly faster performance than the existing Cortex A9 design which is what Apple uses in their A5 processor (iPhone 4S).
Anandtech now reveals, however, that the A6 is a custom Apple design:
The A6 is the first Apple SoC to use its own ARMv7 based processor design. The CPU core(s) aren't based on a vanilla A9 or A15 design from ARM IP, but instead are something of Apple's own creation.
Anandtech explains that Apple is one of a few ARM architecture licensees, which allows them to create their own custom ARM processor designs.
While Anadtech goes into the finer details, the ultimate benefit for Apple is the ability to tune their chips towards their own specific goals. In particular, Apple's design goals prioritize both power and performance while the generally licensable Cortex A15 design was reportedly targeted at server configurations.
Rumor has it that the original design goal for ARM's Cortex A15 was servers, and it's only through big.LITTLE (or other clever techniques) that the A15 would be suitable for smartphones. Given Apple's intense focus on power consumption, skipping the A15 would make sense but performance still had to improve.
Apple seems to finally be benefiting from some previous company acquisitions including P.A. Semi and Intrinsity, both chip design companies. The ability to tune their CPU designs specifically for their products could serve as a competitive advantage over other companies that are reliant on the licensable designs provided by ARM. Apple's previous processor designs have been based on these more traditional designs, so this represents Apple's first departure into a more custom design approach.
While the iPhone 17 Pro and iPhone 17 Pro Max are not expected to launch until September, there are already plenty of rumors about the devices.
Below, we recap key changes rumored for the iPhone 17 Pro models as of April 2025:

Apple may have updated several iPads and Macs late last year and early this year, but there are still multiple new devices that we're looking forward to seeing in 2025. Most will come in September or October, but there could be a few surprises before then.
We've rounded up a list of everything that we're still waiting to see from Apple in 2025.

A common complaint about the iPad Pro is that the iPadOS software platform fails to fully take advantage of the device's powerful hardware.
That could soon change.
Bloomberg's Mark Gurman today said that iPadOS 19 will be "more like macOS."

Apple's upcoming foldable iPhone (or "iPhone Fold") will feature two screens as part of its book-style design, and a Chinese leaker claims to know the resolutions for both of them.
According to the Weibo-based account Digital Chat Station, the inner display, which is approximately 7.76 inches, will use a 2,713 x 1,920 resolution and feature "under-screen camera technology." Meanwhile, the...

Apple in October 2024 overhauled its 14-inch and 16-inch MacBook Pro models, adding M4, M4 Pro, and M4 Max chips, Thunderbolt 5 ports on higher-end models, display changes, and more. That's quite a lot of updates in one go, but if you think this means a further major refresh for the MacBook Pro is now several years away, think again.
Bloomberg's Mark Gurman has said he expects only a small...
Apple is working on a new version of the Vision Pro with two key advantages over the current model, according to Bloomberg's Mark Gurman.
Specifically, in his Power On newsletter today, Gurman said Apple is developing a new headset that is both lighter and less expensive than the current Vision Pro, which starts at $3,499 in the U.S. and weighs up to 1.5 pounds.
Gurman said Apple is also...
