NVIDIA T600 Laptop GPU vs AMD Radeon RX 6600M

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.
