Apple M1 8-Core GPU vs NVIDIA GeForce GTX 1660 Ti (Desktop)

Apple M1 8-Core GPU

The Apple M1 GPU is an integrated graphics card offering 8 cores (1 deactivated core in the entry MacBook Air) designed by Apple and integrated in the Apple M1 SoC. According to Apple it is faster and more energy efficient as competing products (like the Tiger Lake Xe GPU). The peak performance of the high end variant is 2.6 teraflops and thanks to the unified memory architecture it should have fast access to the RAM.

The Apple M1 is manufactured in the modern 5nm process at TSMC and should offer an excellent energy efficiency. According to internal tools, the M1 GPU uses under load approximately 10 Watt (11.5 Watt package power including the RAM).

NVIDIA GeForce GTX 1660 Ti (Desktop)

The Nvidia GeForce GTX 1660 Ti is a powerful, mid-tier, Turing-based, desktop GPU. The GTX 1660 Ti relies on the TU116 chip with 1536 shader units, 48 ROPs, 96 TMUs and a 192-bit-wide memory bus (clocked at 6 GHz, effectively 12 GHz, bandwidth: up to 288 GB/s). The notebook version of the GTX 1660 Ti  is 10 to 20 % slower due to a lower TDP.

The TU116 chip and other Turing-based GPUs are produced using the 12-nm manufacturing process. However, the GeForce GTX 1660 Ti does not offer the latest features such as DLSS (Deep Learning Super Sampling) and Real Time Ray Tracing. Nevertheless, there are some architectural improvements when it comes to floating point and integer performance. These operations can now be carried out simultaneously. Other notable features include Adaptive Shading, unified cache, DisplayPort 1.4, HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) as well as H.265 encoding and decoding (PlayReady 3.0).

At Full HD resolution, the GeForce GTX 1660 Ti performs somewhat worse than the GeForce GTX 1070, but significantly better than the GeForce GTX 1060. Therefore, it is best-suited for Full HD gaming. However, it can run less demanding titles in 1440p.

The energy consumption of the GeForce GTX 1660 Ti amounts to 120 watts. The older GeForce GTX 1060 also has a TDP of 120 watts.
