NVIDIA T600 Laptop GPU vs NVIDIA GeForce GTX 1650 Ti Max-Q

The Nvidia T600 Laptop GPU (or Quadro T600 for laptops) is a professional mobile graphics card that is based on the Turing architecture (TU117 chip). It is similar to the consumer GTX 1650 with 896 CUDA cores and a 128 Bit memory bus for GDDR6 graphics memory (10 Gbits). The chip is manufactured in 12nm FinFET at TSMC. The T600 was introduced as a refresh together with the T1200 and should be slightly slower than the older Quadro T1000 (2.6 versus 2.5 TFLOPS peak SP performance).

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. In contrary to the faster Quadro RTX cards, the T600 do not feature raytracing and Tensor cores.

Currently Nvidia only specifies the TDP of 25 Watt (the older T1000 had a TGP of 40-50 Watt). Therefore, the T600 should be well suited for thin and light laptops.

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 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 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).
