Microsoft SQ1 vs Intel Core i5-9300HF vs Qualcomm Snapdragon 8cx Gen 2 5G
Microsoft SQ1
► remove from comparisonThe 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 i5-9300HF
► remove from comparisonThe Intel Core i5-9300H is a fast processor for laptops with four cores based on the Coffee Lake architecture (2019 Refresh, CFL-HR). The processor clocks at between 2.4 and 4.1 GHz (4 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i5-8300H from 2018, the 9300H is clocked slightly higher (+100 MHz CPU).
Compared to the Core i5-9300H, the integrated graphics card in the 9300HF is deactivated.
The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).
Performance
The Intel Core i5-9300HF should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-8750H/9750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-9300HF should be sufficient for even demanding applications and games. Compared to the Core i5-9300H (see for benchmarks), the performance should be identical.
Power Consumption
Intel specifies the TDP with 45 watts and therefore the i5 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
Qualcomm Snapdragon 8cx Gen 2 5G
► remove from comparisonThe 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.
