Qualcomm Snapdragon 8cx Gen 3 is a high performance Arm SoC designed to compete with Apple M3, with Windows 11 thin and light notebooks and Chromebooks being its main target devices. Microsoft pins a lot of hope in chips such as the Snapdragon 8cx series as they offer comparable performance and battery life to the current crop of M3 MacBooks. A lot of water has flown under the bridge since Windows RT, and the latest crop of Windows 11 for Arm has a much wider PC application support base thanks to official translation layers by Microsoft. CPUID has an Arm64 version of the popular CPU-Z utility, which correctly detects all the specs of the Snapdragon 8cx, but more importantly, has a Bench tab that can test the single- and multithreaded performance of the CPU.

A Chinese tech enthusiast wasted no time in putting the Snapdragon 8cx through this CPU-Z internal benchmark, and found surprisingly good performance numbers. The single-threaded bench, which loads one of chip's four Arm Cortex-X1C P-cores, registers a score of 543.7 points. This is roughly comparable to that of the AMD "Zen 2" or Intel "Comet Lake" x86-64 core. The multithreaded test, which saturates all four P-cores, and all four Cortex-A78C E-cores, springs up 3479.7 points, which again compares to entry/mainstream x86-64 processors from AMD or Intel. Not impressed? How about the fact that the Snapdragon 8cx Gen 3 is a 7 W chip that idles under 2 W for the most part, and can make do with passive cooling, posting scores comparable to 35 W x86 chips that need active cooling?

Benchmark results for Qualcomm's Snapdragon 8cx Gen 4 SoC appeared on Geekbench Browser early yesterday morning, under the designation Snapdragon 8cx Next Gen. This chipset is tipped to be a successor to the Snapdragon 8cx Gen 3, which was launched at the end of 2021 as the world's first 5 nm Arm-based SoC for Windows laptops. A tipster on Twitter has highlighted the very underwhelming results posted by the next gen chipset, and these figures would indicate that an engineering sample was the test subject, not final silicon. The 8-core Snapdragon 8cx Gen 3 is shown to outperform its supposed successor, and the clock frequencies for the latter appear to be lower than anticipated.

The Geekbench 5 database entry for Snapdragon 8cx Gen 4 also reveals details about its specifications - a 12-core configuration that is split into eight performance cores and four power-efficiency ones. The base core frequency is listed as being 2.38 GHz, and the benchmark was completed under a Balanced Power plan in Windows 11 Home Insider Preview. 16 GB of RAM was used in the test kit, although earlier leaks have indicated that the chipset can support up to a maximum of 64 GB LPDDR5 RAM.
