The US chip manufacturer Qualcomm apparently tests faster versions of its Snapdragon 8cx, which is also used in a modified form in the Surface Pro X. Probably a higher clocking of the most powerful core should achieve better performance under Windows 10 for ARM.
The Snapdragon 8cx could sooner or later come in a new, somewhat faster version. For example, import-export databases list a variant that bears the internal model number SC8180XP, while the chip is usually known as SC8180X. We do not know whether the P stands for a kind of “plus” version, as it was last seen in the second half of Qualcomm’s high-end SoCs for smartphones.
More powerful gold+ core
According to our information, the SC8180XP will come with eight cores as before, but Qualcomm apparently finally breaks the 3 gigahertz limit here. There is talk of a 3.15 gigahertz maximum clock rate that the so-called gold cores should achieve. The four economical silver cores continue to run unchanged at a maximum of 1.8 gigahertz.
The clock rates of the Snapdragon 8cx “Plus” would differ significantly from the normal 8cx, in which the gold cores achieve a maximum of 2.84 gigahertz, while the economical “silver” cores reach a maximum of 1.8 gigahertz. It would be conceivable that Qualcomm wants to offer higher average performance with the option of short-term performance peaks and has therefore changed the timing of the cores.
As far as the Adreno 680 GPU used in the Qualcomm SC8180XP is concerned, our information speaks of 718 megahertz. It is open whether the speed of the GPU has changed since Qualcomm has unfortunately never published any official information about the clock rate of the Adreno 680 in the Snapdragon 8cx.
With the information mentioned here, you have to consider that it is information from the manufacturer’s documents that come from a third-party database. In addition, the chip described here is likely to be experimental at the time this data was created, which was in February 2020. The information should, therefore, be enjoyed with some caution and in no way means that Qualcomm will ever make a SoC configured in this way commercially available.
