Therefore, laptops using the Snapdragon 8cx can be passively cooled (no fan) and should not throttle under constant load. The chip is very power efficient as its produced at TSMC in the modern 7 process. 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. The Surface Pro X comes with a Microsoft SQ1 or SQ2 ARM processor, which the company claimed has three times the performance of an x86 MacBook Air. 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. See all specs and frequencies at Microsoft SQ1 is a ARM based SoC for Windows tablets ( Surface Pro X). Contact your service provider for details, compatibility, pricing, SIM card, and activation. Battery life varies significantly with settings, usage and other factors.Ģ Service availability and performance subject to service provider’s network. All settings were default except screen brightness was set to 150nits with Auto-Brightness disabled.
The active use portion consists of (1) a web browsing test accessing 8 popular websites over multiple open tabs, (2) a productivity test utilizing Microsoft Word, PowerPoint, Excel and Outlook, and (3) a portion of time with the device in use with idle applications. Testing consisted of full battery discharge with a mixture of active use and modern standby. Testing conducted by Microsoft in September 2019 using preproduction software and preproduction configurations of Surface Pro X. New 64-bit apps are coming to ARM 64 all the time.ġ Surface Pro X battery life: Up to 13 hours of battery life based on typical Surface device usage. At this time, Surface Pro X will not install 64-bit applications that have not been ported to ARM64, some games and CAD software, and some third-party drivers or anti-virus software. App availability and compatibility may vary. * Some software, apps, and accessories sold separately.
