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?

Yes, I'm unimpressed because the claim falls short once you delve beyond the theoretical specs and into real-world scenarios, where this SoC surpasses 30 watts under stress.

Efficiency isn't a big deal, this SOC is 5nm, and my Ryzen 5 (7nm) laptop gets the same score using just 15-18w.

And then you realize those 35W chips will hit up to 100W while boosting. So yeah, totally unimpressive.

Huh? Do you think any modern laptop doesn't pass this score with half the energy? serious? This thing is 5nm and loses to an AMD CPU from 4 generations ago, still produced in 7nm.

The 8cx Gen 3 is a chip from 2021 though?
Early 2022 in terms of appearing in actual devices, but yes. Not sure if the article is wrong here.

The thing I take away is the fact that ARM is closer to x86 in Windows. How far will it go?

For reference, my Zen 3 Ryzen 9 4900HS CPU on my G14 laptop gets a score in CPUz of SC: 518 | MC: 3926 with a 20W TDP limit...
at 32W TDP I get SC: 521 | MC: 4722
and 12W TDP gets SC: 448 | MC: 2943

The chip is more efficient at lower TDP limits and scores significantly higher as TDP goes down in Cinebench R15

Just a few data points. I enjoy putting together some of these metrics and comparing to what new tech is coming out....

I'm just implying that it's not really newsworthy since it's not a new chip (for reference, the 5800X3D and Raptor Lake was released after this). There are plenty benchmarks available online for this SoC too, unless the news was specifically about the CPU-Z benchmarks.

How is it that SD 8cx gen 3 is 7W part, and the SD 8 gen 3 is a 17W part and that's for phones and tablets.
