Qualcomm Announces Snapdragon 865+: Breaking the 3GHz Threshold

Today Qualcomm is announcing an update to its extremely successful Snapdragon 865 SoC: the new Snapdragon 865+. The Snapdragon 865 had already seen tremendous success with over 140 different design wins, powering some of the best Android smartphone devices this year. We're past the hectic spring release cycle of devices, and much like last year with the S855+, for the summer and autumn release cycle, Qualcomm is providing vendors with the option for a higher-performance binned variant of the chip, the new S865+. As a bit of a[n] arbitrary, but also important characteristic of the new chip is that this is the first ever mobile silicon to finally pass the 3GHz frequency mark.

[...] Whilst in relative terms the new chipset's +10% clock improvement isn't all that earth-shattering, in absolute terms it finally allows the new Snapdragon 865+ to be the first mobile SoC to break past the 3GHz threshold, slightly exceeding that mark at a peak 3.1GHz frequency. Ever since the Cortex-A75 generation we've seen Arm make claims about their CPU microarchitectures achieving such high clock frequencies – however in all those years actual silicon products by vendors never really managed to quite get that close in commercial mass-production designs.

We've had a chat with Qualcomm's SVP and GM of mobile business Alex Katouzian, about how Qualcomm achieved this, and fundamentally it's a combination of aggressive physical design of the product as well as improving manufacturing yields during the product's lifecycle. Katouzian explained that they would have been able to achieve these frequencies on the vanilla Snapdragon 865 – but they would have had a lower quantity of products being able to meet this mark due to manufacturing variations. Yield improvements during the lifecycle of the Snapdragon 865 means that the company is able to offer this higher frequency variant now.

This feat should become more common with the arrival of Cortex-X1 ARM cores and the "5nm" and below process nodes.
