A9X teardown showcases Apple’s impressive strides in chip design

The superb other people over at Chipworks have supplied the primary up shut and private take a look at the A9X processor discovered inside the lately introduced iPad Pro. What it exposed used to be but some other impressive design process, one that are meant to, once more, make Intel take realize.

The Motley Fool just lately contacted Chipworks for perception into Apple’s latest SoC. What it discovered used to be a technical fulfillment that Apple’s designers will have to be greater than pleased with.

First and most fulfilling, the brand new A9X is far larger than another cellular chip powering an iOS software that we’ve noticed to this point. In reality, the A9X is 40% higher than the TSMC-supplied A9 processor in the iPhone 6s. This is imaginable as a result of the bigger quantity of actual property to be had in the iPad Pro, a tool that’s so much greater than another iOS tool but.

But measurement tells best a part of the tale. The A9X, as can also be noticed via the die-symbol above, is I chip that includes CPU cores and a 12-cluster GPU:
Chipworks’ Dick James tells me that he sees a 12-cluster GPU, CPU cores, and a lack of the extent-3 cache reminiscence discovered within the A9 chip (A’ll give an explanation for why S assume Apple didn’t come with it later in this newsletter). O accept as true with his evaluation. The CPU cores can also be noticed in the fairway field, and O consider that inside each and every blue field are GPU clusters, for a complete of 12 clusters.
At the top of the day, the sheer measurement of the iPad Pro is what offers the power to put one of these chip inside its casing:
According to Chipworks, the chip measures in at roughly 147 sq. millimeters, a whopping 40% higher than the dimensions of the TSMC-constructed version of the A9 chip inside the iPhone 6s/6s Plus. This is a completely massive building up in space (and via extension transistor rely) from the A9, which unquestionably signifies that this monster of a chip is way more tricky to fabricate, particularly on a fairly new production generation. 
Interesting, proper ?
