Apple M4 Max 40-Core GPU vs Apple M2 10-Core GPU vs Apple M2 Max 38-Core GPU

Apple M4 Max 40-Core GPU

The Apple M4 Max GPU (40 cores) is an integrated graphics adapter that's built into the 16-core Apple M4 Max SoC. It features 40 "cores" and has access to at least 48 GB of fast 546 GB/s LPDDR5x on-package RAM depending on the configuration. As is typical for graphics adapters released in 2024, it has hardware support for ray tracing as well as mesh shading and other modern technologies. It also supports external displays with resolutions as high as "8K" and can HW-decode a few popular video codecs such as h.264, h.265 and AV1.

Performance

Its gaming performance is set to be approximately as good as that of the GeForce RTX 4070 Laptop. Please keep in mind that very few games have been compiled specifically for Apple silicon Macs meaning most titles have to be run via emulation layers. Some of them are displayed with visual artefacts as a result, or don't start at all.

Power consumption

Given the power on offer, we expect the iGPU to consume over 45 W when under heavy loads.

Just like the rest of the Apple M4 Max chip, the integrated graphics adapter is manufactured on a "second generation 3 nm" TSMC process which is still cutting-edge as of late 2024.

Apple M2 10-Core GPU

The Apple M2 GPU is an integrated graphics card offering 10 cores designed by Apple and integrated in the Apple M2 SoC. It uses the unified memory architecture of the M2 SoC (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth) and should offer 160 execution units.

According to Apple it offers a 25% higher performance at slightly higher power consumption. The theoretical performance is rated at 3.6 Teraflops and therefore 1 TFLOP higher than the M1 8-core GPU. In our benchmarks, the GPU was able to top the M1 with up to 40%, but still stays behind the 14-core GPU in the M1 Pro. Compared to other iGPUs from AMD and Intel, the M2 benefits greatly from the unified memory architecture and the high bandwidth.

The M2 chip is manufactured in the second generation 5nm process at TSMC (most likely N5P). The power consumption is around 13.5 Watt (in our tests under load of the MBP13) and up to 15W according to Apple.

Apple M2 Max 38-Core GPU

The Apple M2 Max 38-Core-GPU is an integrated graphics card by Apple offering all 38 cores in the M2 Max Chip.

The graphics card has no dedicated graphics memory but can use the fast LPDDR5-6400 unified memory with a 512 bit bus (up to 400 GBit/s).

Thanks to the additional cores and architectural improvements, the M2 Max GPU should clearly best the old M1 Max GPU with 32 cores and therefore be the fastest iGPU currently available.

The GPU is intended to use Apple Metal 2 API and could still be based on the older PowerVR architectures (last used in the Apple A10). A new feature in the MacBook Pro 14 and 16 of 2023 is the support for HDMI 2.1 and 8k output.

The Apple M2 Max is manufactured in the second generation 5nm process at TSMC. According to the internal powermetrics tool, the GPU uses up to 53.6 Watt (performance mode) and the whole chip (including the CPU) up to 89 Watt.
