NVIDIA GeForce GTX 1660 Ti Mobile vs NVIDIA GeForce GTX 1660 Ti (Desktop) vs NVIDIA GeForce GTX 1650 Max-Q

The Nvidia GeForce GTX 1660 Ti for laptops is a mobile graphics card that is based on the Turing architecture (TU116 chip). Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1660Ti integrates no Raytracing or Tensor cores. The performance is similar to the old GTX 1070 (laptop) but at a reduced TGP of 80 Watt (versus 115 Watt). Compared to the desktop GTX 1660 Ti, the clock speeds are reduced (3% lower base, 10% lower boost).

In April 2020 Nvidia refreshed the GTX 1660 Ti with the new codename N18E-G0-A1 with similar specs and pin compatible to the refreshed RTX chips (e.g., RTX 2070 Super Mobile).

The Turing generation did not only introduce raytracing for the RTX cards, but also optimized the architecture of the cores and caches. According to Nvidia the CUDA cores offer now a concurrent execution of floating point and integer operations for increased performance in compute-heavy workloads of modern games. Furthermore, the caches were reworked (new unified memory architecture with twice the cache compared to Pascal). This leads to up to 50% more instructions per clock and a 40% more power efficient usage compared to Pascal.

The power consumption of the 1660Ti for latops is specified at 80 Watt TGP (Total Graphics Power) by Nvidia and therefore 20 Watt higher than the efficient (and slower) Max-Q variant of the 1660 Ti. The TU116 chip is manufactured in 12nm FFN at TSMC.

The Nvidia GeForce GTX 1650 with Max-Q design is a mobile graphics card that is based on the Turing architecture (TU117 chip). Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 integrates no Raytracing or Tensor cores. Compared to the desktop version, the mobile and Max-Q versions use all 1024 shaders of the TU117 chip. It is designed for thin and light laptops and about 10-15% slower than a regular GTX 1650 for laptops (depending on the cooling capabilities). According to the specifications, the Max-Q variant clocks 20% slower for the base speed and 27% for the boost speed.

Beginning March 2020, the GTX 1650 Max-Q is also available with fast 4GB GDDR6 (N18P-G61).

The performance should be slightly faster than the old GeForce GTX 1050 Ti Max-Q. 

The Turing generation did not only introduce raytracing for the RTX cards, but also optimized the architecture of the cores and caches. According to Nvidia the CUDA cores offer now a concurrent execution of floating point and integer operations for increased performance in compute-heavy workloads of modern games. Furthermore, the caches were reworked (new unified memory architecture with twice the cache compared to Pascal). This leads to 50% more instructions per clock and a 40% more power efficient usage compared to Pascal.

Compared to the bigger Turing chips (like the TU116 of the GTX 1660 Ti and the RTX lineup), the TU117 does not include the new NVENC encoder but an older one similar to the one used in Pascal and Volta.

Nvidia specifies a power consumption of 35 Watt TGP (Total Graphics Power) and therefore 15 Watts lower than a normal (Max-P) 1650 for laptops. Therefore, the Max-Q variant is well suited for thin and light laptops. The TU117 chip is manufactured in 12nm FFN at TSMC.
