Qualcomm Snapdragon 8cx Gen 3 vs Apple M3 Pro 11-Core vs Apple M3 Max 16-Core

Qualcomm Snapdragon 8cx Gen 3

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).

Apple M3 Pro 11-Core

The Apple M3 Pro 11 Core is a system on a chip (SoC) from Apple for notebooks that was introduced late 2023. It integrates 11 of the 12 CPU cores with 5 of 6 performance cores with up to 4.06 GHz and 6 efficiency cores with 2.8 GHz.

Compared to the M2 Pro the M3 Pro has been slimmed down somewhat and swaps two performance cores for efficiency cores. This is due to the changed core configuration, as 6 cores are now used per cluster (the M2 Pro and M3 still have 4 cores per cluster). Furthermore, the memory bus has been reduced from 256 bits to 192 bits (150 GB/s vs. 200 GB/s). Thanks to the new architecture and higher clock rates, the new M3 Pro is still slightly faster.

The M3 Pro also integrates a new graphics card with dynamic caching, mesh shading and ray tracing acceleration via hardware. In the entry-level model, only 14 of the chip's 18 cores are used and support up to 3 displays simultaneously (internal and 2 external).

GPU and CPU can jointly access the shared memory on the package (unified memory). This is available in 18 or 36 GB variants and offers 150 GB/s maximum bandwidth (192 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.

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 37 billion transistors (-7.5% vs. Apple M2 Pro).

Apple M3 Max 16-Core

The Apple M3 Max (16 Core) is a system on a chip (SoC) from Apple for notebooks that was launched towards the end of 2023. It integrates a new 16-core CPU with 12 performance cores with up to 4.06 GHz and 4 efficiency cores with 2.8 GHz. There is also a slimmed-down 14-core variant with a 30-core GPU.

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 (such as a Core i9-13900HX).

The M3 also integrates a new graphics card with dynamic caching, mesh shading and ray tracing acceleration via hardware. In the top model, all 40 cores of the chip 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 48, 64 and 128 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). Under load, the CPU part consumes up to 56 watts, the chip can use a total of 78 watts.
