GPU Performance & Power

GPU performance of the new A14 is something that wasn’t very clearly presented during the launch of the new iPhone 12 series. Apple had first introduced the A14 within the new iPad series where it had promised performance increases relative to the A12, not the previous generation A13, and with a bit of math this resulted into a translated 8.3% generational increase which is rather smaller than we had expected given Apple’s recent GPU trajectory over the years. Furthermore, this was also the first release where Apple compared itself to the Android SoC competition which is something the company doesn’t usually do. All these factored into some rather low expectations for the GPU of the A14 – so let’s see how that pans out in practice:

Basemark GPU 1.2 - Medium 1440p - Off-Screen / Blit

Starting off with Basemark GPU 1.2, we’re seeing a 17% increase in peak performance relative to the iPhone 11 Pro and the A13 chip, which is a nice upgrade, but doesn’t tell the whole story. In the sustained performance figure after 30 minutes of running and when the phone reaches a thermal equilibrium, we see a 45% drop in performance. In this instance, it looks like the iPhone 12 Pro reached a lower sustained performance level than the iPhone 11 Pro which isn’t a great start, but that might change with differing workloads.

GFXBench Aztec Ruins - High - Vulkan/Metal - Off-screen

In the Aztec High test, the iPhone 12’s fare a bit better in their sustained performances, with the new chip showing a 21% increase in performance generationally. The peak performance figure is only 11% higher but generally this isn’t the figure that is important for gaming experiences on iPhones.

Galaxy S10+ (Exynos 9820) 8LPP 15.59 4.80 3.24 fps/W

Looking at the power consumption of the new phones, we see again that both the peak and throttled performance figures of the new chip isn’t all that much different to the previous generation, as we’re seeing roughly 8% better performance at almost the same power envelope of around 3.9W. The peak power figure of the new chip seems to have been reduced this generation and that’s very much a welcome change, and that’s where the efficiency sees the largest delta to the A13.

GFXBench Aztec Ruins - Normal - Vulkan/Metal - Off-screen

In the normal setting configuration of the Aztec test, we’re seeing again a 11% increase in sustained performance generationally, and a similar 12% boost in peak performance. These are good improvements but still a bit less than we had expected given the A14’s new process node and new GPU.

The power figures showcase a similar generational movement, with a slight performance increase at a slight power decrease. It’s good progression but again not quite fulfilling our expectations of a new process node bump.

Depending on the workload, the generational performance increases can be even smaller, as here in Manhattan the performance increase in a throttled state is only 3% better for the new A14 based iPhone, with also a minor power decrease at this state.

Finally, T-Rex showcases no improvements on the part of peak performance figures, although it does lower power consumption, and sustained performance for some reason is lower on the newer generation iPhone, although again it showcases quite lower power consumption so it’s possible the new chip is mainly running on the efficiency CPU cores in this workload.

Reasonable Upgrades

Generally speaking, our concerns over Apple’s lacklustre marketing on the GPU side of things seem to have been warranted as the new A14 and the 5nm process node doesn’t seem to bring substantial gains this generation. Performance is a little higher, and efficiency has also gone up as well, but it’s nowhere near the levels of improvements that Apple had been able to achieve with the A12 and A13. On one side that’s pretty understandable as those two generations had made huge leaps, and on the other hand it was maybe unreasonable to expect Apple to continue to make such gigantic strides on every generation.

Overall, the new iPhone 12 devices and the A14 still offer the very best gaming performance of any smartphone out in the market, showcasing significantly better experiences than any other Android competitor, but it’s also not a major noticeable upgrade over the iPhone 11 series devices.

    Basically every smart phone released since forever has quite a few threads about battery drain problems from some users. You also need to take into account the population size here. I'm sure Apple has sold more than a million units across the range already. My anecdotal rebuttal to anecdotal accounts of problems is that my 12 Mini with the smallest battery has surprised me with how good the battery life is. I skipped charging it a few nights ago and went to sleep with 62%. In the morning it was down to 56%. No low power mode, no turning off any radios, and it was losing less than 1%/hour at idle with all the usual suspects like multiple Gmail accounts, an Exchange account, Facebook etc. setup. Just before midnight the next night it was down to 10%. TL;DR: I think they can all make it through a day of "average" use easily. Reply

    There are definitely some 5G issues with this switch to a new modem/radio. I’d think that between Apple and Qualcomm they have enough engineering resources to dial it in. Reply

    Phones looks simmilar. Difference is much bigger then you picture even it does not look like that in normal use. Let see all differences.

    128 GB so real difference is 150 (130) USD
    6 GB RAM
    Telephoto: ƒ/2.0 aperture with OIS
    2x optical zoom in, 2x optical zoom out; 4x optical zoom range
    Digital zoom up to 10x
    Lidar
    Night mode portraits enabled by LiDAR Scanner
    Apple ProRAW
    Dolby Vision recording up to 60 fps
    Durable steel frame you do not preffere
    Brighter display

    I think RAM, extra lens with OIS, Lidar and brighter screen can easily justify hugher cost.
    And 100 USD for Max is really small difference for bigger screen and battery, better image sensor with extra stabilisation when we speak in Apple prices.

    I hever had rounded phone so can not comment your feelings from flat edges. ... Sorry I had 3/3GS but it so long time ago and were quite bulky.
    I would try to compare those phones in cases as many ppl wear them anyway.

    Not exciting at all...Personally that move back to the iP4 design is the biggest "upgrade", as I've always felt that to be more premium, just like Razer etc. are all making their laptops more boxy. The camera would be more of a sidegrade. Reply
