Qualcomm Snapdragon 8cx vs Apple M3 Max 14-Core vs Apple M3
Qualcomm Snapdragon 8cx
► remove from comparison![Qualcomm SD 8cx](fileadmin/_processed_/7/8/csm_snapdragon_8cx_small_bf3c1da8ac.jpg)
The Qualcomm Snapdragon 8cx Compute Platform (or SD8cx) is a ARM based SoC for Windows laptops. It integrates a similar CPU part as the Snapdragon 855 (same cores but without the Prime Core feature) and is manufactured in 7nm at TSMC. The 4 Kryo 495 Gold cores are based on the ARM Cortex-A76 architecture (for performance) and clocked at 2.84 GHz under load (no single core Turbo). The 4 Kryo 495 Silver cores are small ARM Cortex-A55 cores for power efficiency and clocked at 1.9 GHz under load. According to Qualcomm, the clock speed should not be reduced under constant load with typical (fanless) cooling. The integrated X24 LTE modem supports up to 2 Gbps download speeds. Furthermore, the SoC integrates ac-Wifi and a dual-channel 32-bit 1866 MHz LPDDR4x memory controller.
The processor performance should be similar to a Intel Core i5 8th gen U-series (e.g. i5-8250U) according to Qualcomm. However, this is only the case for native ARM64 compiled Windows apps which are not that many (in mid 2019). 32 bit applications and games for AMD/Intel run in a rather slow emulation and 64 bit apps wont start at all (but an emulator should come in Windows in 2021).
The integrated Adreno 680 graphics card is a beefier version of the Adreno 640 in the Snapdragon 855 and should be twice as fast as the old Adreno 630 (in Windows laptops) and offer a 60% higher efficiency.
The chip is very power efficient as its produced at Samsung in the modern 7 nm process (7LPP). Therefore, laptops using the Snapdragon 8cx can be passively cooled (no fan) and should not throttle under constant load.
Apple M3 Max 14-Core
► remove from comparison![Apple Apple M3 Max 14-Core](fileadmin/_processed_/d/9/csm_Apple-M3-Max-chip-series-unified-memory-architecture_c0044e24af.jpg)
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).
Apple M3

The Apple M3 is a system on a chip (SoC) from Apple for notebooks that was introduced in late 2023. It integrates a new 8-core CPU with 4 performance cores with up to 4.06 GHz and 4 efficiency cores running at up to 2.75 GHz. Apple claims that the CPU is up to 20% faster than in the old Apple M2 (3.5 GHz).
Due to the higher clock speeds and architecture improvements, the processor performance is also significantly better than the M2 in benchmarks (see e.g. Geekbench below) and can keep up with the fastest CPUs in short single-core tests (like the Raptor Lake i9-13950HX).
The M3 also integrates a new graphics adapter with dynamic caching, mesh shading and ray tracing acceleration. According to Apple, it is 20% faster than the GPU in the M2. The chip integrates again 10 GPU cores, but the cheaper variant only offers 8 cores (e.g. in the entry iMac). Furthermore, the GPU only supports 2 displays (an additional 6K60 display to the internal one).
Both GPU and CPU can access the unified memory on the package together. It is still available in 8, 16 and 24 GB variants and offers the same 100 GB/s maximum bandwidth (unlike the Pro models that feature a reduced memory bandwidth).
The integrated 16-core Neural Engine has also been revised and now offers 18 TOPS peak performance (versus 15.8 TOPS in the M2 but 35 TOPS in the new A17 Pro). The video engine now supports AV1 decoding in hardware. H.264, HEVC and ProRes (RAW) can still be decoded and encoded.
Unfortunately, the integrated wireless network module only supports Wi-Fi 6E (no Wi-Fi 7) and due to the support of only a single external monitor, the chip also has to make do with no Thunderbolt 4 (Thunderbolt 3 / USB 4 support only for up to 40 Gbit/s).
The chip is manufactured on the current 3nm TSMC process (N3B most likely) and contains 25 billion transistors (+25% vs. Apple M2). The 3nm process should also contribute to the excellent efficiency of the chip. Under load, the M3 CPU consumes approximately 20 Watt.
