NVIDIA GeForce GTX 1080 Max-Q vs Apple M3 Pro 14-Core GPU vs Apple M3 Max 40-Core GPU

NVIDIA GeForce GTX 1080 Max-Q

The Nvidia GeForce GTX 1080 with the Max-Q design is a mobile high-end GPU from the Pascal series. It is designed for thin and light laptops and about 10-15% slower than a regular GTX 1080 for laptops based on the cooling capabilities. The base frequency (1101-1290 MHz) is also much lower than on the regular GTX 1080 (1566 MHz, at least -18%) and the Boost (1278-1458 MHz) is also much lower compared to 1733 MHz (at least -16%) for the regular GTX 1080. The memory clock, however, is identical.

The clock is not the only difference compared to the regular GTX 1080 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

The performance is nearer to the normal (Max-P) GeForce GTX 1070 than to then GTX 1080 (at least in the Asus Zephyrus). Therefore, most demanding games should be playable in full HD and maximum detail settings (see game benchmarks below).

Features

The GP104 chip is manufactured in 16nm FinFET process at TSMC and offers a range of new features. DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP), improved H.265 video en- and decoders (for PlayReady 3.0) are only some of the improvements. See our detailed Pascal architecture article for more details.

The power consumption of the Max-Q design is notably lower than the normal GTX 1080 for laptops and ranges between 90 and 110 Watt (TGP) according to Nvidia.

Apple M3 Pro 14-Core GPU

The Apple M3 Pro 14-Core GPU is a self-designed graphics card in the Apple M3 Pro (with 11 CPU cores) and offers fourteen of the eighteen cores available on the chip. The graphics card uses a new architecture and now offers dynamic caching, mesh shading and ray tracing acceleration.

The GPU can access up to 24 GB LPDDR5-6400 unified memory via a 192-bit memory bus (max 150 GBit/s). Thanks to dynamic caching, the GPU only reserves as much memory as is required.

The entire chip is manufactured in the current 3nm process (probably N3B) at TSMC.

Apple M3 Max 40-Core GPU

The Apple M3 Max 40-Core GPU is a self-designed graphics card in the Apple M3 SoC and according to Apple with forty cores. According to Apple, the GPU uses a new architecture and now offers dynamic caching, mesh shading and ray tracing acceleration.

The GPU can access up to 128 GB LPDDR5-6400 unified memory via a 512 bit memory bus (max 400 GBit/s). Thanks to dynamic caching, the GPU should only reserve as much memory as is required.

Since the SoC is manufactured in the current 3nm (probably N3B) at TSMC. According to powermetrics, the GPU requires up to 60 watts (chip incl. CPU total 78 watts).
