Today Qualcomm is disclosing a set of benchmark results for their new Snapdragon 888 SoC that’s set to power next year’s flagship Android devices. Usually, as in years past, we would have had opportunities to benchmark Qualcomm’s reference designs ourselves during the chipset launch event, or a few weeks later during CES. However due to obvious circumstances, this wasn’t possible this year.

As an alternative, Qualcomm is instead sharing with the press a set of benchmark results from their new Snapdragon 888 reference design phone. Usually, the point of having the press benchmark the devices themselves is that it adds independent verification of the benchmark scores. This time around we’ll have to make a little leap of faith in the accuracy of Qualcomm’s numbers – of course we still pretty much expect the figures to be accurate and be reproduced in commercial devices.

Unfortunately, because the majority of our more interesting mobile test suite around SoCs is comprised of custom internal benchmarks, that means that those will be missing from today’s rather brief coverage.

Among the benchmarks that Qualcomm has run are AnTuTu, GeekBench, GFXBench Aztec Normal and Manhattan 3.0, Ludashi AiMark, AITuTu, MLPerf and UL Procyon. We really only run a subset of those benchmarks are part of our regular coverage, so I’ll just be focusing on the very basics with GeekBench, GFXBench and Procyon.

GeekBench 5

Starting off we have GeekBench 5, which in my opinion is generally a good overall performance benchmark for CPUs, and generally scales in line with SPEC. Here we see the new Snapdragon 888’s first-time use of Cortex-X1 cores in action.

The single-threaded performance score has gone up from 919 points on the Snapdragon 865 to 1135 on the new SoC, a 23.5% performance uplift versus its direct predecessor. This is relatively in line with Qualcomm’s promoted performance boost of 25%, and generally is what we expected given Qualcomm’s implementation of the Cortex-X1 in the new chipset. As a reminder, the new X1 cores are clocked at 2.84GHz – the same frequency as the A77 cores on the S865, but lower than the 3.09GHz A77 cores of the Snapdragon 865+. As a result, against the 865+ the 888's performance advantage is only 15.4%, which doesn’t sound quite as exciting.

Multi-threaded performance of the new chip comes in at 16.9% better than its predecessors. This actually was a bit odder to see as I was expecting larger improvements. Thinking more about it, I guess it makes sense – the new Cortex-A78 core, which is being used as the 3x middle cores of the new SoC, is only advertised as offering a 7% IPC advantage over its predecessor.

Meanwhile, Qualcomm did increase their L2 cache size on the middle cores from 256KB to 512KB, but otherwise left their clock frequencies unchanged at 2.42GHz. Together with the unchanged 4x Cortex-A55 cores at 1.8GHz I guess the overall performance for the complete cluster hasn't really changed all that much, with the X1 prime core being the hero of the show for this generation.

Moving on to GPU performance, the new Snapdragon 888 features the new Adreno 660 GPU, where Qualcomm promises a 35% performance uplift. Qualcomm published GFXBench Aztec Normal and Manhattan 3.0 scores. We moved on from Manhattan 3.0 to Manhattan 3.1 long time ago, so we don’t have comparison scores against Qualcomm’s 169fps figure, but we do run Aztec Normal.

In this benchmark, Qualcomm’s listed score of 86fps is over 55% faster than previous generation Snapdragon 865 devices. This might be an outlier score, or it could be sign of the benefits of the additional memory bandwidth afforded by the SoC's faster LPDDR5-6400 support – Qualcomm did say that this generation the GPU will be able to stress that part of the chip much harder.

While the Snapdragon 888 doesn’t look like it’ll match the peak performance scores of the A13 or A14 SoCs used in Apple's iPhones, sustained performance will depend quite a bit on the power consumption of the chip. If this lands in at between 4 and 4.5W, then the majority of flagship Android phones in 2021 will likely be able to sustain this peak performance figure and allow Qualcomm to regain the mobile performance crown from Apple. Otherwise if the chip has to significantly throttle, then 888 will probably fall short of retaking the crown. But even if that's the case, for Android users it shouldn't matter too much: the generational leap over 2020 phones would still be immense, and by far one of the largest GPU performance leaps Qualcomm has been able to achieve to date.

UL Procyon

In terms of AI Benchmarks, Qualcomm didn’t really present anything in the same manner that we do, so this is a good opportunity to add UL’s new Procyon AI Inference benchmark to our suite.

The benchmark is able to run on various accelerators blocks within an SoC, and it's also is able to take advantage of custom TensorFlow Delegates, such as Samsung’s EDEN framework.

Here the new Snapdragon 888 is posting outstandingly good performance, delivering almost 3x the score of the Snapdragon 865+ and outright exceeding the theoretical throughput rate increases of the new Hexagon 780. The new Hexagon is a completely new IP and pretty much the single biggest improvement of the whole Snapdragon 888 as it promises great advancements in performance and power efficiency – not only against previous generation Snapdragons but also against competitor designs which don’t yet have such a flexible DSP/ML hardware block in their SoCs.

MLPerf 0.7.1 - Image Classification MLPerf 0.7.1 - Image Classification (Offline) MLPerf 0.7.1 - Object Detection MLPerf 0.7.1 - Image Segmentation MLPerf 0.7.1 - Language Processing

Qualcomm surprisingly also published MLPerf results on the new chip. The Android version of MLCommons' benchmark suite is fresh out the oven, and among other things, gives us a new standardized test that’s more aligned across the industry.

The new Snapdragon 888 is showcasing tremendous performance leaps compared to its predecessor, with gains of up to 4x in some of the tests. Again, this is well beyond just the theoretical computational throughput improvements of the execution units of the IP blocks, and very likely is tied to the new memory architecture of the new Hexagon block as a whole.

Overall Good First Impressions – Waiting For First Devices

Following up on its announcement just a few weeks ago, today’s benchmark score release helps to further validate our first impressions of (and expectations for) Qualcomm's new Snapdragon 888 SoC.

On the CPU side we’re seeing good improvements, even with Qualcomm's conservative claims. And meanwhile the new Adreno GPU seems to perform as well as Qualcomm has promised – if not a bit better. So as things stand, the missing piece of the puzzle is power consumption; if it ends up being competitive there, then Qualcomm has a shot at regaining the performance crown in mobile.

Finally, the new Hexagon DSP really stood out as being the most exciting piece of new hardware in the Snapdragon 888. These performance figures underscore just how far Qualcomm has come in a single generation, as evidenced by the new SoC's tremendous performance leaps over earlier chips.

Ultimately, while this isn't really one of our traditional performance previews – seeing as how we have to place trust in Qualcomm that their figures will be reproducible on commercial devices – it's at least a starting point for talking about performance. And, with that taken at face value, it’s looking like the new Snapdragon 888 won’t disappoint, setting up Qualcomm for another solid year of execution on the SoC front.

    +23.5% performance is a nice improvement, but I can’t help but be a little disappointed when Arm was claiming +30% IPC *and* frequency increases. Here’s hoping that Qualcomm is just being conservative with peak performance for the smartphone chips to save power, and that the 8CX equivalent will be able to run at higher frequencies!
  • arayoflight - Friday, December 18, 2020 - link

    Qualcomm went with half the cache compared to ARM's configuration to save costs. Also they are doing 0 frequency increases.

    Qualcomm has nothing to gain from a faster chip. They have zero competition and it's better for margins to make a more cost efficient chip.

    Half the L3 cache for the whole cluster, but Qualcomm’s using the full 1 MB L2 cache for the X1 core.
  • techconc - Tuesday, December 22, 2020 - link

    No, I believe this was Anandtech's misinterpretation. I remember reading ARM's information on the X1 and disagreeing with Anandtech's assessment. ARM's claim of 30% performance improvement for X1 assumes process node bump AND clock speed of 3Ghz. You can see this in their slides, it's in the fine print. ARM didn't mislead anyone, in this case Anandtech's analysis did.
  • toyeboy89 - Friday, December 18, 2020 - link

    Okay I don't like the route they're going with a single- X1 core, Apple has 2 high performance cores in parallel isn't this way more powerful?
  • fierysnowman - Friday, December 18, 2020 - link

    Apple has two very high performance cores, Qualcomm has one high performance and three medium-high performance cores.

    Apple dedicates around twice as much die area as Qualcomm to CPU cores and private cache, yet Qualcomm gets 70-90% of their performance at similar efficiency. That’s very quite decent. Not very exciting, but pragmatic.

    Apple also controles the entire stack. We cant run android on an iphone to test this, but I'd wager part of the A core's performance is due to top to bottom optimization that just doesnt happen on android devices.
  • fierysnowman - Monday, December 21, 2020 - link

    I have my doubts the optimization are anything only iOS would benefit from. More so they optimize against specific use cases common on an iPhone or iPad, such as web browser JavaScript, which the M1 is exceedingly proficient at and other browsers also benefit from.
  • Hyper72 - Friday, January 1, 2021 - link

    People always say that but I disagree. Apple really makes great general purpose CPUs. Many benchmarks and applications compiled for standard ARM64 flies on them and even ARM Windows shows fantastic performance running inside a VM. They have lots of general purpose features: Like that 8-wide decoding with a huge ROB and large+fast caches. The only other CPU with similar architecture is the big iron POWER10 (as mentioned by Anandtech).
  • fishingbait - Friday, December 18, 2020 - link

    The reason is that the X1 core is brand new. It was a joint design project by ARM Holdings and Samsung to catch up to Apple Ax and it was just completed last year. Qualcomm, Samsung and the rest went from a big.Little 4+4 architecture to a 1+3+4 architecture awhile back because they knew it was on the way. Getting 2 X1 cores to match the Apple A14 will be next. I would be shocked if Samsung isn't already working on it because that is basically their only path to competing with Qualcomm since they have given up on custom cores. After that it will be getting to 4 Cortex X1 chips like the M1. Hopefully they will achieve it by the time they get to a 3nm process in 2022.
