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 Apple M3 Max 14 core CPU is a system on a chip (SoC) from Apple for notebooks that was introduced towards the end of 2023. It integrates a new 14-core CPU with 10 performance cores with up to 4.06 GHz and 4 efficiency cores with 2.8 GHz. There is also a more powerful 16-core variant with 40 GPU cores.
Thanks to the higher clock rates and architectural improvements, the processor performance is also significantly better than the M2 Max in benchmarks and can keep up with the fastest mobile CPUs.
The M3 also integrates a new graphics card with dynamic caching, mesh shading and ray tracing acceleration via hardware. In the cheaper model, 30 of the chip's 40 cores are used and support up to 5 displays simultaneously (internal and 4 external).
GPU and CPU can jointly access the shared memory on the package (unified memory). This is available in 36 and 96 GB variants and offers 400 GB/s maximum bandwidth (512 bit bus).
The integrated 16-core Neural Engine has also been revised and now offers 18 TOPS peak performance (compared to 15.8 TOPS in the M2 but 35 TOPS in the new A17 Pro). The video engine now also supports AV1 decoding in hardware. H.264, HEVC and ProRes (RAW) can still be decoded and encoded. Like its predecessor, the Max chip offers two video engines and can therefore encode and decode two streams simultaneously.
Unfortunately, the integrated WLAN only continues to support WiFi 6E (no WiFi 7), unlike the small M3 SoC thunderbolt 4 is also supported (max 40 Gbit/s).
The chip is manufactured in the current 3nm process (N3B) at TSMC and contains 92 billion transistors (+37% vs. Apple M2 Max).
