Today Qualcomm is announcing a new small refresh of the Snapdragon 855 SoC: the new Snapdragon 855+. In the past Qualcomm had the habit of sometimes refreshing their flagship SoCs in the middle of their product life and give them a small performance boost, probably the most known chip fitting this pattern was the Snapdragon 821 from a few years ago. The S835 never got an upgrade, however the S845 last year did get a higher bin variant which ended up in a few vendor’s products, including the renamed Snapdragon 850 product that featured the same specifications.

The new Snapdragon 855+ today closely follows this pattern: It’s overall the same SoC as the Snapdragon 855, however Qualcomm is raising the clocks of the Prime CPU core from 2.84GHz to up to 2.96GHz, giving a 4.2% boost for single-threaded workloads.

Along the CPU boost, we also find that the GPU is receiving a larger 15% performance boost. As the Adreno 640 in the 855 was clocked in at 585MHz, the clock on the 855+ has to be around the 672MHz mark, which is an oddly familiar frequency of Adreno GPUs.

Qualcomm states that we should expect hearing about vendor devices using the new Snapdragon 855+ in the next few weeks. Last year, ASUS was the first vendor to announce the ROG Phone using a higher binned S845 around the same summer time-period, and now the company has confirmed that the ROG Phone II will be also the first to use the new S855+.

I’m also guessing that it’s possible that Samsung’s upcoming Note10 to be powered by the S855+ as I’m expecting the phone to come with a new Exynos chipset this time around, and the Snapdragon counterpart getting a small boost as well would also make sense.

    Is this an actual upgrade or just an SKU that will require heatpipes and fan phones for real benefit ? Reply

    Considering it is just a 4% CPU bump and 15% GPU bump, I doubt it will need more cooling. Keep in mind the Snapdragon 845 took over an extra watt of power to run so I doubt you will need to go crazy with the cooling on the 855. Reply

    Thanks Andrei! These "higher binned" SoCs always makes me wonder about the significant number of the lower-binned ones. Wonder who's getting those? Hmm... Reply

    Just to clarify: I don't mean the "on spec" ones, rather the silicone making up the bottom third of still-functioning 855s. Reply

    I remember back in the 820 days Xiaomi was taking 1.8GHz base clock chips vs 2.2GHz on the on spec 820s, for its base model 32GB Mi 5 phones. Reply

    *Almost*, but not quite, a nice round 3 GHz clock.. The GPU performance boost is quite more significant though. I wonder if Qualcomm retained the same TDP or if it also got a "boost" upwards. Reply

    very interesting also to know Reply
