MagyarMicrosoft SQ1 vs Intel Core i5-1034G1
Microsoft SQ1
► remove from comparison
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.
Intel Core i5-1034G1
► remove from comparison
The Intel Core i5-1034G1 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Ice -Lake-U generation that was announced in Mai 2019 (Computex). It integrates four Sunnycove processor cores (8 threads thanks to HyperThreading) clocked at 0.8 (base) - 3.6 (single core Turbo) GHz. 2 cores can reach 3.6 GHz and all four 3.3 GHz using Turbo Boost. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock) and therefore the CPU performance should be similar to the higher clocked Whiskey-Lake predecessors (e.g. Core i5-8365U with up to 4.1 GHz).
The biggest improvement for Ice-Lake is the integrated Gen 11 graphics card called UHD Graphics G1. The Core i5-1034G1 integrates the smallest GPU, the UHD Graphics that features 32 of the 64 CUs and clocks at 300 - 1050? MHz. The faster variants include Iris Plus G4 and G7.
Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).
The Core i5-1034G1 is produced in the improved 10nm+ process at Intel (2nd generation) that should offer a comparable performance to the 7nm process at TSMC. The TDP is specified at 15 Watts and therefore the CPU can be used in thin and light laptops (but usually with a fan). Intel offers a configurable TDP of 7.5 - 25 Watts for the partners resulting in significant performance differences (due to longer periods of Turbo Boost).
