Apple M3 Max 40-Core GPU vs NVIDIA GeForce GTX 1070 SLI (Laptop) vs Apple M3 8-Core GPU

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).

NVIDIA GeForce GTX 1070 SLI (Laptop)

The Nvidia GeForce GTX 1070 SLI for laptops is a combination of two GTX 1070 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1070 to up to 90% faster performance. In most games with SLI support, the GTX 1070 SLI is therefore faster than a single GTX 1080. However, sometimes the combination also suffers from micro-stuttering.

The technical details of the card are identical to a single GTX 1070 (see for more information) and the power consumption is doubled. Therefore, the 1070 SLI combination is only found in huge clunky laptops.

Apple M3 8-Core GPU

The Apple M3 GPU is an integrated graphics card offering 10 cores designed by Apple and integrated in the Apple M3 SoC. It uses the unified memory architecture of the M3 SoC (up to 24 GB LPDDR5-6400 with 100 GB/s bandwidth). The GPU uses a new architecture with support for mesh shading and ray tracing. Dynamic caching is also a new feature that should only us as much shared memory as needed.

The old M2 SoC showed a difference of around 15% between the 8-core and 10-core variant. Therefore, we expect a similar difference for the M3 models. This means, the M3 8-core version should be slightly faster than the 10-core GPU in the Apple M2.

The M3 chip is manufactured in the new 3nm process at TSMC (most likely N3B). The power limit should be around the same 15 Watt as the 10-core variant.
