Qualcomm has introduced the third generation of the Snapdragon 8cx and 7c compute platforms with the high-end 5nm Snapdragon 8cx Gen 3 processor offers up to 85% faster CPU and 60% faster GPU performance compared to Snapdragon 8cx Gen 2, while the Snapdragon 7c+ Gen 3, designed for entry-level and mid-range laptops and Chromebooks, is said to gain up to 60% CPU performance and achieve up to 70% faster GPU performance uplift compared to the Snapdragon 7c Gen 2.
Qualcomm Snapdragon 8cx specifications:

With only DX12 API officially supported by the GPU, Qualcomm clearly reserves this processor for Windows 11 laptops. Just like previous models, the main advantages of Qualcomm Arm processors over their x86 equivalent are the long battery life (up to 25+ hours on a charge), and built-in 5G connectivity. The performance gap is now lower with Qualcomm saying a 9W Snapdragon 8c Gen3 has the same performance as a 22W Intel Core-i5 processor, or 25% more performance when using a 15W TDP instead.
Windows 11 always-on always-connected devices from Microsoft, Lenovo, and Motorola are expected to come to market in H1 2022. More details may be found on the product page.

Since the Snapdragon 7c+ Gen 3 is not only designed for Windows 11 laptops but also Chromebooks according to the press release, it could be easier to port Linux to it. Devices based on the processor are also expected in H1 2022. Additional information may be found on the product page.
As a side note, Qualcomm also launched the Snapdragon G3x for gaming, notably portable gaming consoles, and unveiled the “Handheld Gaming Developer Kit” designed in collaboration with Razer.
