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

While the autonomy of these machines was impressive (up to 25 hours for this laptop from Lenovo), against 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 unveiled the Snapdragon 8cx platform developed specifically for Windows computers on Arm. Qualcomm does not take gloves: this system-on-chip is simply " the most extreme Snapdragon ever ! It slams.

On paper, this chip impresses. This is the first PC engine engraved in 7 nm (take that Intel!), Able to compete or even better than 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 that the chip of Qualcomm is satisfied with a TDP of 7 watts.

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

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