Microsoft SQ1 vs Qualcomm Snapdragon 8cx Gen 2 5G

Microsoft SQ1

► remove from comparison Qualcomm SQ1

The Microsoft SQ1 is a ARM based SoC for Windows tablets (Surface Pro X). It is based on the Snapdragon 8cx but with higher clocked CPU and GPU cores. The CPU cores clock with up to 3 GHz. 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). 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 integrated X24 LTE modem supports up to 2 Gbps download speeds. Furthermore, the SoC integrates ac-Wifi and a dual-channel 32-bit 1866 MHz LPDDR4x memory controller.

The processor performance should be similar to a Intel Core i5 8th gen U-series (e.g. i5-8250U) according to Qualcomm. However, this is only the case for native ARM64 compiled Windows apps which are not that many (in mid 2019). 32 bit applications and games for AMD/Intel run in a rather slow emulation and 65 bit apps wont start at all.

The integrated Adreno 685 graphics card is a higher clocked version of the Adreno 680 in the Snapdragon 8cx. Microsoft claims 2 TFlops theoretical performance compared to the 1.8 for the Adreno 680 (+11%).

The chip is very power efficient as its produced at TSMC in the modern 7 process. Therefore, laptops using the Snapdragon 8cx can be passively cooled (no fan) and should not throttle under constant load.

Qualcomm Snapdragon 8cx Gen 2 5G

► remove from comparison Qualcomm SD 8cx Gen 2 5G

The Qualcomm Snapdragon 8cx Gen 2 5G Compute Platform (or SD8cx Gen2, SC8180XP) is a ARM based SoC for Windows laptops. It integrates a similar CPU part as the Snapdragon 855 (same cores but without the Prime Core feature) and is manufactured in 7nm at Samsung. The 4 Kryo 495 Gold cores are based on the ARM Cortex-A76 architecture (for performance) and clocked at 3.15 GHz under load. The 4 Kryo 495 Silver cores are small ARM Cortex-A55 cores for power efficiency and clocked at 1.8 GHz under load (most likely).

Compared to the predecessor, the Snapdragon 8cx, the Gen 2 offers higher clock speeds and an integrated 5G modem (X55 with Sub-6 GHz and mmWave support). Wi-Fi was also bumped up to Wi-Fi 6

The processor performance should be similar to a Intel Core i5 8th gen U-series (e.g. i5-8250U) according to Qualcomm. However, this is only the case for native ARM64 compiled Windows apps which are not that many (in mid 2019). 32 bit applications and games for AMD/Intel run in a rather slow emulation and 64 bit apps wont start at all (but an emulator should come in Windows in 2021).

The integrated Adreno 680 graphics card could also be a bit higher clocked.

The chip is very power efficient as its produced at TSMC in the modern 7 process. Therefore, laptops using the Snapdragon 8cx can be passively cooled (no fan) and should not throttle under constant load.
