Microsoft claims 2 TFlops theoretical performance compared to the 1.8 for the Adreno 680 (+11%). The integrated Adreno 685 graphics card is a higher clocked version of the Adreno 680 in the Snapdragon 8cx. 32 bit applications and games for AMD/Intel run in a rather slow emulation and 65 bit apps wont start at all. However, this is only the case for native ARM64 compiled Windows apps which are not that many (in mid 2019). The processor performance should be similar to a Intel Core i5 8th gen U-series (e.g. Furthermore, the SoC integrates ac-Wifi and a dual-channel 32-bit 1866 MHz LPDDR4x memory controller.

The integrated X24 LTE modem supports up to 2 Gbps download speeds. The 4 Kryo 495 Silver cores are small ARM Cortex-A55 cores for power efficiency and clocked at 1.9 GHz (unverified) under load. The 4 Kryo 495 Gold cores are based on the ARM Cortex-A76 architecture (for performance) and clocked at up to 3 GHz (2.84 GHz for the 8cx) under load (no single core Turbo). It is based on the Snapdragon 8cx but with higher clocked CPU and GPU cores. The Microsoft SQ1 is a ARM based SoC for Windows tablets ( Surface Pro X).
