Apple has a new top system-on-a-chip for smartphones, the A20 Pro. The new processor, alongside a new in-house modem, the C2, was debuted at Apple's iPhone event today, the first led by newly minted chief executive officer John Ternus.The A20 Pro is Apple's first 2-nanometer chip in an iPhone. (Its first-ever 2 nm chip is the M6, which the company announced in August and will debut in the Mac Mini later this month). Like M6, the A20 features dual neural engines, new CPU and GPU cores.The new SOC boasts a 6-core CPU with two of the company's super-cores (20% faster than last generation), while there are also four efficiency cores with neural accelerators. Apple is calling this a "desktop-class" processor and the "fastest CPU in a smartphone."The 7-core GPU has a 40% boost gen-over-gen with increased bandwidth, along with new neural accelerators that the company says allows for twice as faster FP8 compute.The two neural engines have a combined 32 total cores. There's a 50% increase in memory bandwidth on the chip, which Apple says is the widest memory interface in an iPhone.Apple has also changed the packaging, with the silicon dies placed in a way that removes memory from the thermal path of the SOC, allowing the silicon to attach directly to the vapor chamber.That vapor chamber has a three times larger surface area over the 17 Pro, and also includes more graphite and copper along with 80% recycled stainless steel.The company claims that this will allow for up to 40% sustained performance over the iPhone 17 Pro, and 2x sustained performance over the 16 Pro.Apple says that A20 Pro's efficiencies and new battery designs allow more battery. The company claims the Pro will get 36 hours of video playback, and 45 hours on Pro Max video. Using a proprietary test based on data of how people use their phones, Apple claims 24 hours per charge on the 18 Pro, and 30 hours on Pro Max.The A20 Pro will power the iPhone 18 Pro and Pro Max, coming in black, silver, a light blue "glacier", and burgundy, featuring matching back glass, rather than the light contrast with aluminum the previous phones had.The iPhone 18 Pro will start at $1,199, while the Pro Max will start at $1,299.Developing...
