Microsoft SQ1 has 8 cores, 4 large cores are based on ARM Cortex-A76 architecture, the highest frequency is 3GHz; 4 small cores are based on ARM Cortex-A55 architecture, the frequency is 1.9GHz. In addition, its GPU is the latest Adreno 685.
Due to the limitations of the ARM architecture, many commonly used Windows performance evaluation software runs more or less on the Surface Pro X. Some will report an error during the test, and some simply cannot be installed.
Cross-platform CPU performance testing software GeekBench 4 can run normally on Surface Pro X. In particular, GeekBench 4 provides two test environments, ARM and X86, for selection, so we can compare the performance of Microsoft SQ1 in the two environments.
In the GeekBench 4 test, the single-core performance score under the ARM environment is 3246, and the multi-core performance score is 9496. Compared with the test scores in the X86 environment, both the single-core score and the multi-core score have a lead of about 50%.
In chess, the Surface Pro X has a performance multiple of 10.88 and a score of 5222.
PCMark 10 provides an application test for ARM-based Windows systems to compare performance across platforms. In this test summary, several application speeds will be tested in a basic office environment, including Word, Excel, PowerPoint, and Edge browsers.
In the 3DMark 11 test, the P score was 1974.
The new version of 3DMark launched a special Night Raid test project for low-performance devices, which is quite suitable for testing ARM Windows devices.
3DMark 11's Night Raid test, Surface Pro X scored 7061 points.
6. Disk performance test
SK Hynix's NVME solid state, in the ASS SSD BenchMark, sequential read and write results were 1510MB / s, 425MB / s, 4K random read speed 20.58MB / s, random write speed 51.52MB / s.
In CrystalDiskMark, sequential read and write reached 1968MB / s and 729MB / s, 4K random reads were 24.07MB / s, and random writes were 49.59MB / s.
7.Memory bandwidth test
The memory read, write, and copy bandwidth are 23280MB / s, 33742MB / s, and 36107MB / s, respectively.
According to the running test results, Microsoft SQ1 uses the X86 environment that simulates running the Window system, but there will still be some losses. Under the two environments of X86 and ARM, the single-core and multi-core performance scores vary greatly. In general, it can be said that the SQ1 in the ARM environment is almost equivalent to the Intel six-generation low-voltage Core i5-6200U with dual-core four-threads and 2.3-2.8GHz frequency. Even when using UWP applications, it will perform better.
Through the PCMark 10 application test to test the performance of the actual office, the actual office experience of Microsoft SQ1 is slightly inferior to the dual-core four-thread, 2.5-3.1GHz frequency Intel 7th generation low-voltage version Core i5-7200U, but it is significantly ahead of the above The performance of the flagship Snapdragon 855 on a notebook.
The GPU performance is surprising. Compared to Intel HD 620 graphics card, Adreno 685 on Microsoft SQ1 has a 40% lead in the Night Raid test of 3DMark 13. At least the performance on UWP games will be Even better.
