Snapdragon 8cx: an "extreme" chip to power Windows on Arm – MacGeneration


If Qualcomm put the package for its new Snapdragon 855 mobile platform, the US group has not forgotten its Microsoft partner in the adventure of Windows on Arm. Until now, these "always connected" computers on Windows 10 were satisfied with the Snapdragon smartphone chips, which were slightly adapted to PC needs.

While the autonomy of these machines was impressive (up to 25 hours for this laptop from Lenovo), compared to the performance often left to be desired (read: 🐌 The first Windows 10 PC on ARM is a snail 🐌).

Qualcomm takes the bull by the horns and during the Snapdragon Summit, the company presented the Snapdragon 8cx platform developed specifically for Windows computers on the Arm. Qualcomm does not take gloves: this on-chip system is simply " the most extreme Snapdragon ever "!

@Myriam Joire.

On paper, this chip impresses. This is the first PC engine recorded in 7 nm (take that Intel!), Able to compete or even better than the traditional "desktop" processors. The performance of the Snapdragon 8cx would be comparable to the Intel U Series processors (those of the MacBook Pro), whose thermal envelope is 15 watts, except for the fact that the Qualcomm chip is satisfied with a TDP of 7 watts.

Compared to a processor of the Y series, similar to the Core i5 of the new MacBook Air, Snapdragon 8cx would be 50% faster. From a graphical point of view, Adreno 680 Extreme next to the CPU is announced twice as fast as the Snapdragon 850 GPU, the chip in the heart of the Windows PC on Arm recently released. It also supports two external 4K HDR monitors, compared to a previous one.

All without fans and keeping the "always connected" aspect and the autonomy of several days. The first Windows PC on the Arm equipped with Snapdragon 8cx will however be launched only from the third quarter of 2019.
