NVIDIA T600 vs NVIDIA T500 Laptop GPU

The Nvidia T600 Desktop GPU is a professional graphics card for workstations that is based on the Turing architecture (TU117 chip). The desktop version only offers 640 of the 1024 cores and therefore also less than the T600 mobile (896 CUDA cores). The card offers 4 GB GDDR6 graphics memory connected with a 128 bit bus (up to 160 GB/s bandwidth). The T600 supports certified drivers (former Quadro line) for professional applications like CAD, 3D modelling, DCC, medicine, or visualization applications.

The maximum power consumption of the card is rated at 40W.

The Nvidia T500 Mobile (formerly known as Quadro T500) for laptops is a professional mobile graphics card that is based on the Turing architecture (TU117 chip). It is based on the consumer GeForce MX450 and features the same 896 cores and a 64 Bit memory bus. Currently it is available with 2 or 4 GB graphics RAM (GDDR5 or GDDR6). The TDP ranges between 18 - 25 Watt depending on the variant. As the MX450, the T500 also supports PCIe 4.0. The chip is manufactured in 12nm FinFET at TSMC. 

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 T500 does not feature raytracing and Tensor cores.
