NVIDIA GeForce GTX 1650 Ti Mobile vs NVIDIA GeForce GTX 1650 Ti Max-Q

The Nvidia GeForce GTX 1650 Ti Mobile is a dedicated mid range graphics card for laptops based on the Turing architecture. It uses the same TU117 chip as the desktop version but for the mobile GPU all 1024 shaders are enabled. Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 Ti integrates no Raytracing or Tensor cores. 

There are two packages of the GTX 1650Ti, the GB4D-128 with a 128 Bit memory bus and a TGP of 50 Watt and the GB4B-256 with a 256 Bit memory bus and a TGP of 55 Watt (compatible with the faster RTX cards). The clock rates seem to be identical for both versions, therefore, the 256 Bit version should be faster.

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.

The power consumption of the 1650 Ti for laptops is specified at 50 - 80 Watt TGP (Total Graphics Power) by Nvidia and therefore 5 - 25 Watt higher than the GTX 1650. The power efficient Max-Q variant of the GTX 1650 Ti is rated at 35 Watt TGP.

The Nvidia GeForce GTX 1650 Ti Max-Q (N18P-G62) is a dedicated mid range graphics card for laptops based on the Turing architecture. The Max-Q variant is the power saving version of the mobile GTX 1650Ti with reduced clock speeds, performance and of course power consumption. It is using the same TU117 chip with 1,024 shaders. Therefore, it is intended for thin and light gaming laptops. Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 Ti integrates no Raytracing or Tensor cores.

There are two variants of the 1650Ti Max-Q, one with 35 Watt and 1035 - 1200 MHz and a faster 40 Watt version with a clock speed of 1200 - 1365 MHz. Both however are significantly lower clocked than the normal Max-P version with 50 / 55 Watt and 1350-1385 MHz. The memory is most likely clocked at 1250 MHz = 10,000 MHz effective (Gbps) in most laptops, although there might be versions with 1500 MHz = 12,000 Gbps.

The power consumption of the 1650 Ti Max-Q laptops is specified at 35 Watt TGP (Total Graphics Power) by Nvidia and therefore 25 Watt lower than the mobile GTX 1650 Ti in the same package (other variants can reach up to 80 Watt).
