Performance is not just the only goal for Apple having a brilliant in-house SoC design team. It's also a carefully planned out move to retain as much control over their end product. It's amazing how hardware nerds focus so much on benchmarks that they don't get the latter.

But that's true whether or not Apple has the kind of performance advantage that they have. We were discussing whether or not that performance edge is all that meaningful in the smart phone space, where I don't think it matters much (although Commodus does point out some interesting examples of where it could matter in the future), but as I and others have said it could matter more in the tablet or desktop space.

Here are the browser benchmark speedups going from iOS 9 to iOS 10.

iOS 10 reviewed: There’s no reason not to update





What this also tells us is that the iDevice browser benchmarks posted earlier are actually all on iOS 10, so OS differences are not a factor. The speedup from A10 is really that much, and it's not due to the OS/Safari update, because they're all running the same version.



A9 -> A10: 1.34X
A8 -> A10: 2.07X
A7 -> A10: 2.54X

OTOH, stuff like app loading is slightly slower on old hardware in iOS 10.

I remember reading an article minimizing the performance increase of the iPhone 7 since it was only 40% faster than the A9. LOL. The reality is that Apple has intentionally downplayed what a huge a performance leap they made. I suspect to avoid comparisons with their Pro and computer models. I'm excited to see this processor or an X variant in the iPad Pro and I hope a custom one made for the MacBook.

The mainstream tech media lauded Apple for stupid cosmetic crap in the early innings of the smartphone boom and called it "innovative." Now that Apple's technical innovation is starting to be quite serious in chips and other tech, these same people say that iPhone 7 is boring/derivative/etc. Can't help but roll my eyes.

Indeed. But then again, much of the press echoes what mainstream consumers think about this stuff, partially because they don't really understand it fully.

For example, the iPhone 6 was hailed as a much needed size upgrade and therefore a must have, but not much was said about the limited RAM at 1 GB, when the iPhone 5 shipped two years earlier with the same 1 GB RAM despite having a much smaller screen. In some ways the iPhone 6 was more derivative than the iPhone 7 Plus, IMO.

People have been saying the new iPhone is boring/derivative/etc. for years now and some people are just looking for any reason to pooh-pooh it regardless of any technical merits. Apple still does some innovate things, but they're not the kind of thing that customers probably care that much about. I suspect that they're doing a lot of great and interesting things with their manufacturing process and with the materials from which the devices are constructed, but the average consumer doesn't care about that at all as they can't measure the tangible benefits in a meaningful way.

The video where they showed off how their new black finish is done was pretty interesting, but it isn't going to improve the battery life or enable new exciting apps that couldn't exist before, so customers don't care at all whether or not Apple had to invent new processes and techniques in order to pull of that finish. The technical improvements are much the same, where unless you're a tech enthusiast who likes to geek out over CPUs, the new A10 chip isn't going to feel that much different in day to day use for most phone users. It might load an app .1 seconds faster or give another 20 minutes of battery life, but those are hard to notice or even care about if the battery already lasted all day and the app loaded in under a second.

I do agree the fanbase's knee-jerk reactions are a turn-off. They are not limited to Apple, though.

On the A10 "Fusion": So is the logical explanation is that A10's big cores are consuming too much power when doing trivial stuff? Or, in a similar but a slightly different vein, that Apple wanted to target certain performance (say, 50% higher than A9) and that required pushing the big cores too far, which necessitated the introduction of LITTLE cores?

Not automatically, no. There are some kinds of long running but undemanding processes which inevitably will consume less power when running on a small core than a big one, no matter what you do to gate down the big one. Stuff like lowering the power use when the phone is basically in standby.

All of the swapping stuff between cores is messy, but Apple should have enough control over their software/hardware - and resources - to make sure that it'll work out.

It's not a question of trivial or not, it's an issue of energy economy.

If a process is memory bound, it doesn't matter how fast a processor is, memory communications speed is the limiting factor. So a memory bound thread will run just as fast (reasonably) on the efficiency cores as they would on the performance cores. So why use the extra energy? There's no real performance hit.

I bet the efficiency cores are designed to synchronize with the load/store latency.

You're also going to get threads that aren't doing any heavy floating point math and or logic branches that will run better on a short pipelined efficient core. You know, kernel level stuff.

This is for the 3 GB iPhone 7 Plus.



Apple A10 Fusion APL1W24 SoC + Samsung 3 GB LPDDR4 RAM (as denoted by the markings K3RG4G40MM-YGCH)

Qualcomm MDM9645M LTE Cat. 12 Modem

-----


Below is the Chipworks teardown for the 2 GB iPhone 7. The die size is smaller than most here predicted.

http://www.chipworks.com/about-chipworks/overview/blog/apple-iphone-7-teardown

The A10 die size is ~125 sq. mm and we have the A10 processor in our lab now so we can confirm the die node technology very soon..

But whatever node is being used, the A10 processor is incredibly thin, giving credibility to the reports that TSMC’s InFO packaging technique is being used.

The A10 sits below the Samsung K3RG1G10CM 2-GB LPDDR4 memory. This is similar to the low power mobile DRAM as the one we found in the iPhone 6s. Looking at the X-rays we see the four dies are not stacked, but are spread out across the package. This arrangement keeps the overall package height to a minimum. Assembled in a package-on-package assembly with the A10 InFO packaging technique reduces the total height of PoP significantly.

Apple's aggressive approach to SoC performance suggests that they want to try to make their own processors for all of their products lines at some point. They don't care about competing with Qualcomm or Samsung as much as they want to be able to beat Intel, at which point they're that much closer to vertical integration for their traditional computing platforms.

I agree but I also think it is much more than that. Having an amazing SoC means that stuff like autonomous driving becomes a lot easier, think to their car project. Ultimately, they have (according to recent rumors) thankfully scrapped the idea of building a car on their won and settled for their core competency, selling the stuff that car makers can use to power their self-driving cars.

I wouldn't be surprised if Apple came out with a VR and/or AR headset in the near future, which would also be greatly helped by a beastly SoC. Once you have this level of computing power, the possibilities incrementally open up the horizons further and further away.

Especially in a context of slowing smartphone sales and the fact that tablets are, by and large, a failed paradigm, Apple needs pathways to diversify. A strong SoC business would give them a lot of possibilities in all directions.

A4: 53.3 mm2 Samsung 45 nm
A5: 122.2 mm2 Samsung 45 nm
A5r2: 69.6 mm2 Samsung 32 nm
A5 (1 core): 37.8 mm2 Samsung 32 nm
A5X: 165 mm2 Samsung 45 nm
A6: 96.7 mm2 Samsung 32 nm
A6X: 123 mm2 Samsung 32 nm
A7: 102 mm2 Samsung 28 nm, over 1 billion transistors
A8: 89 mm2 TSMC 20 nm (although some say Samsung also made some), 2 billion transistors
A8X: 128 mm2 TSMC 20 nm, 3 billion transistors
A9: 96 mm2 Samsung 14 nm, over 2 billion transistors
A9: 104.5 mm2 TSMC 16 nm, over 2 billion transistors
A9X: 147 mm2 TSMC 16 nm
A10: ~125 mm2 TSMC 16 nm, 3.3 billion transistors

So, this makes A10 Fusion the largest iPhone SoC Apple has ever created, but it's actually very similar in size to the original A5 in my iPad 2 (which I am still using with iOS 9). However, the A5 was shrunk later by a significant amount with a die shrink. A10 Fusion is quite a bit smaller than most of the X variants for the iPads though. I wonder if there will be an A10X, and if so, how big it will be.

The A10 die size is huge for a phone SoC. Apple is really killing it in performance against the Android crowd. TSMC InFO technology is providing some significant power, cost and height/area benefits. The A10 is the pinnacle of mobile chip innovation.

I wonder if TSMC could ramp up 10 nm quick enough to produce A10 Fusion for the second half of the iPhone 7 model year, much like what happened to A5. A5 in the iPad 2 was fine, but the A5 iPhone 4S suffered from battery life issues. When they released the A5r2 in the iPad 2, they kept the battery the same, which meant that the battery life of the A5r2 iPad 2 was way better.



Apple says the iPhone 7 will have better battery life than its predecessor, but it would be interesting to see the comparative battery life of a 10 nm iPhone 7.

Assembled in a package-on-package assembly with the A10 InFO packaging technique reduces the total height of PoP significantly.

The A10 using TSMC's Integrated Fan-Out (InFO) has bigger implications than thinner packaging, it also indicates much faster memory access and bandwidth while a significantly lower power usage, This is a perfect fit with the new efficiency cores and significantly improves the GPU performance. That they are using Samsung LPDDR4 indicates that they got the process into mass production since they are now packaging disparate components on the same wafers.

The next generation A11 can continue this by integrating silicon from the W1for bluetooth and possibly from Qualcomm and Intel for LTE+ not to mention other components on the logic board. Pretty serious power savings to come, while increasing performance.

Now I want to see the die size normalized for wafer price . In any case x'tor density with those 3.2B ones is astounding. Probably the only piece of the silicon that is not crapped up with SRAM and dense logic are the 2 HP cores.

BTW, the Chipworks iPhone has Intel modem, so congrats to Intel.

It's the cell transceiver and amps, the XMM basebands aren't just the modem it's the whole RF stack as well, it was always part of any Intel/Infineon solution.

I don't even know how a modem exactly works and how it's made (like does it have an architecture like a CPU, what does it do).

A10x is on TSMC 10nm.
With InFO, the wafer package can mix such that the GPU can be 16nm, the various cores 10nm, etc. Now we will need to wait for the X-Rays to ascertain which part is at which scaling. Unless Apple tells us outright. Typically SRAM is the first to shrink. Look at the SoC package as taking over the function of the Logic Board, now that interconnects can be done on the wafer instead.

BTW, the A10 sure looks a lot like what ARM is doing with HBM2 on their high-end discreet GPUs with regard to the RAM...

I came across this article from June 2015:

---

The capital expenditure required for 10nm, however, is approximately $2 billion for 10,000 WPM, and a facility running 40,000 WPM will cost $8 billion. Also, the minimum cost for a design at 10nm will be $150 million, so if revenues for a chip need to be ten times higher than design costs to get a good return on the investment, 10nm chips will need to achieve sales of $1.5 billion.

---

We have wafer cost increase of 17.7% for 10nm over 16FF+.

Available gates per wafer increase is 39.3%.

We expect wafer cost for 10nm to be about $5.2K

Does Intel have an equivalent of InFO?

So I looked this up myself and I came across this:

Vardaman said Intel, by virtue of its acquisition of Infineon’s wireless operation, is an early adopter. Intel’s Wireless Division uses fan-out packaging for an LTE multichip part that measures just 5.32 by 5.04 mm.
