Qualcomm Snapdragon 8cx Gen 2 5G Compute Platform Offers 50% Greater Performance, Longer Battery Life

Qualcomm Snapdragon 8cx 5G processor was launched last year for always-on always-connected PC and delivers a similar performance of 15W Intel Comet Lake processors with much lower power consumption enabling 20+ hours battery life.

The company has now an update with Snapdragon 8cx Gen 2 5G Compute Platform with 50% greater system-wide performance and battery life versus “competing solutions”. More on that later.

The parts that are stricken-through are probably not removed from the chip, and simply not listed in the specs. The second-generation processor has virtually no visible differences except for support for a new Hexagon DSP, WiFi 6 connectivity, and the Bluetooth version has been bumped to 5.1. That’s probably why the company did not bother comparing Gen 1 vs Gen 2, and instead only offered charts comparing it to 7W and 15W Intel processors.

Snapdragon 8cx Gen 2 5G vs Intel Comet Lake & Lakefield

The 15W Intel Core i5 processor is probably a Comet Lake processor such as Intel Core i5-10210U, and the 7W Hybrid Core i5 is clearly an Intel Core i5-L16G7 Lakefield processor.  Qualcomm Snapdragon 8cx Gen 2 5G is up to 51% faster than Lakefield processor, and 18% faster than the Comet Lake processor, while also offering higher efficiency.

The Acer Spin 7 will be the world’s first notebook powered by the Qualcomm Snapdragon 8cx Gen 2 5G compute platform. The laptop will feature a 14-inch FHD display, ship with a dockable Wacom AES 1.0 pen with 4,096 levels of pressure sensitivity, and weight around 1.4 kg.

Acer Spin 7 Snapdragon 8cx Gen 2 5G LaptopThat’s about all we know about the laptop right now, but we’ll find out more soon since it’s slated to launch before the end of the year.

More details may be found on the press release and product page.

ROCK 5 ITX RK3588 mini-ITX motherboard

    1. Likewise, then it would really fly. If the price were low enough and the amount of RAM high enough I could be tempted to gamble on Windows Subsystem for Linux though

    2. I think it’s very interesting… provided that a Linux distribution is developed for it.
      The RK3388 will be less performant but will certainly have GNU/Linux in SBC, maybe in an evolution of the PineBook Pro…

  1. Note that they’re comparing *total* system performance, for 8 cores vs 4 cores/8 threads. It’s still very good, but single-core performance is a very important factor, especially on the desktop.
