Apple M3 vs Qualcomm Snapdragon 8 Gen 2 vs Apple M3 Max 16-Core

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.

Qualcomm Snapdragon 8 Gen 2

The Qualcomm Snapdragon 8 Gen 2 Mobile Platform is a high-end SoC for smartphones that was introduced in late 2022 and manufactured in 4 nm at TSMC (N4P). It integrates four different CPU clusters. A fast and big prime core based on the ARM Cortex-X3 architecture and clocked at up to 3.2 GHz for 64 bit applications. Two more ARM Cortex-A715 based performance cores clocked at up to 2.8 GHz (also only for 64 bit apps). Two more Cortex-A710 performance cores at up to 2.8 GHz that can also be used for older apps and three efficiency cores (ARM Cortex-A510 with up to 2 GHz). All cores can use the shared 8 MB level 3 cache.

Thanks to the new architecture and high clock rates, the SD 8 Gen 2 is the fastest mobile CPU for Android based devices and is only topped by current Apple SoCs like the Apple A16 (see benchmarks below).

The chip also integrates a Hexagon accelerator for AI workloads (tensor, scalar and vector). Qualcomm states that its one of the first chips with INT4 support and up to 4.35x performance compared to the previous generation. 

The 18-Bit-Spectra ISP is able to process photos with up to 200 MP and work with videos up to 8k30 (including 10-bit, HDR10+, HLG and Dolby Vision).

A big improvement of the Snapdragon 8 G2 is the integrated Adreno 740 GPU, that now supports Hardware Raytracing and tops even the iGPU in the Apple A16.

The integrated AI Engine can offer up to 4x faster AI performance thanks to the bigger Tensor engine. The 18-Bit-Spectra-ISP also saw some big improvements and is now called Snapdragon Sight.

The integrated Adreno 730 offers a 30% graphics boost compared to the previous Adreno 660.

The integrated Snapdragon X70 5G modem is also new as is the FastConnect 7800 modem with Wi-Fi 7 and Bluetooth 5.3 support.

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.
