The Qualcomm Snapdragon 8cx Gen 3 Compute Platform is an ARM based SoC for Windows laptops. It integrates four big ARM Cortex-X1 performance cores (up to 3 GHz) and four smaller ARM Cortex-A78 with up to 2.4 GHz.
The Compute Platform also integrates a Snapdragon X62 5G modem with up to 10 Gbps download and 316 Mbps upload. The integrated WLAN modem supports Wi-Fi 6E (2x2) and the satellite positioning system supports BeiDou, Galileo, GLONASS, GPS, QZSS, and SBAS. The integrated video engine supports H.264, H.265, and VP9 decoding in 4K 120fps.
The performance should be around 85% faster for the CPU and 60% faster for the GPU compared to the previous generation (Snapdragon 8cx Gen 2).
The chip is produced in the modern 5nm process at Samsung (5LPE) and designed for fanless laptops (7 to 9 Watt TDP range).
The AMD Athlon Gold 7220U is a mobile processor for cheap laptops of the Mendocino series. It integrates two older Zen 2 cores (similar to the Ryzen 4000 series). The CPU cores clock from 2.4 GHz (base) to 3.7 GHz (single core Turbo) and can use 4 MB L3 cache. Thanks to SMT/Hyperthreading, the CPU can work on 4 threads simultaneously. The integrated memory controller only supports fast LPDDR5 memory (5500 MHz max.). Compared to the faster Mendocino models like the Ryzen 5 7520U, the 7220U offers only two cores and reduced clock speeds, leading to a clearly lower CPU performance.
The integrated graphics card (Radeon 610M iGPU) uses the modern RDNA 2 architecture, but only 2 CUs (128 shaders) and clocks with up to 1.9 GHz.
The CPU performance should be better than the fastest Ryzen dual-core (Ryzen 3 3250U, 2.6 - 3.5 GHz, Zen 1) but clearly stay behind modern quad-core CPUs (in multi threaded tests).
The Mendocino series are produced in a relatively modern 6nm FinFET process at TSMC and should offer a good power efficiency. The Athlon Gold 7220U is rated at 8-15 W TDP and therefore well suited for thin and light laptops.
The AMD Athlon Gold 7220C is a mobile processor for cheap chromebooks of the Mendocino series. It integrates two older Zen 2 cores (similar to the Ryzen 4000 series).

Compared to the faster Mendocino models like the Ryzen 5 7520C, the 7220C offers only two cores and reduced clock speeds, leading to a clearly lower CPU performance. The 7220C offers the same specifications as the Athlon Gold 7220U.
