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.

    If we take some rumors Apple will be focusing on power efficiency with A15 and potentially it can be 4+4 design. They do not need to push sigle thread performance much but not sure how they can fit 2 more cores on die.
    Also CPU performance in mobile world becoming nearly irrelevant as chips are blazing fast and more focus is now put on AI and graphic. From this point is 888 interesting and I wonder how all will be able to utilize. Let see what it brings to users and if it will leapfrog Apple in this.
    In desktop ARM designs I wonder if they catch up in two years somehow or some other vendor.

    The problem is, nothing can touch Apple's single core performance. There is nothing stopping any chip maker from topping Apple's multi-core performance. Qualcomm could simply just add more cores.

    Qualcomm doesn't design their own CPU cores anymore, so it's really up to ARM to decide if that's where they want to go. I thought that was what the X1 was supposed to be for. The X1 seems to be what the A78 should have been.

    Agreed that there is no real need to add more cores for a phone chip. There are already thermal limitations to deal with. Qualcomm had done the right thing by focusing on AI/ML and making their GPU more competitive.

    1. All the mobile vendors, save Apple, only make tiny changes to the arm core design ← this is by far the dominant factor, but there's a reason why the X-1 is their first "big" core & that's....
    2. Cost. Any of the core designers at the various companies could explain how to design a competitive core to Apple's but the core will be huge... just like Apple's ← for fast non-mobile arm-based cores look to arm's neoverse, Qualcomm's falkor, Calcium's thunderx/2,

    Because selling such chips would be commercially unviable. Apple's chip division has no such restriction and can therefore build bigger chips or get in early on the newest process. Most of apple's success is actually a result of tsmc rather than apple. Reply

    One: Qualcomm is using a much worse process node, Samsung 5nm is around 2/3 as dense as TSMC 5nm. This has a huge impact on especially low wattage performance.

    Secondly, cache. Cache is probably one of the more expensive things you can do to increase performance of a chip, e.g. Architecture change is once off, but cache will be paid linearly, so it's usually one of the cases where cost cuts are seen first if they can get away with it.

    Qualcomm doesn't need to beat Apple, they just need to beat the rest of the Android competition.

    Why not just ship reference design devices to reviewers ?

    Nothing aggainst preventing thespred of viruses, but just posting supposed numbers as “best of the best” in every category seems suspicious as if there was a caveat or two.

    Do we at least know if RD was a tablet or smartphone ? Or any info at all ?

    Doesn't matter. The first batch of phones containing this new chip will be out in less than month, whether it will be the Samsung Galaxy S21 phones that launch January 14th or a Chinese phone that beats it to market by a week or 2. Either way it won't be much longer before we have independent benchmarks. Reply

    When was the last time qcom provided unreliable perf?
    They're obviously going to cherry pick the particular benchmarks but their actual results should be replicable. In the past these initial benchmarks tend to be on the lower side.
    In this case, there's no reason to be suspicious... HOWEVER, power draw is a completely different matter.

    Another BIG unknown is the process performance, given that this will be made on samsung 5nm process and not on TSMC. Reply

    Agreed. We already know transistor density is not as good on the Samsung process. Probably similar for performance. Reply
