This article provides in-depth details of the NVIDIA Quadro RTX “Turing” GPUs. NVIDIA “Turing” GPUs bring an evolved core architecture and add dedicated ray tracing units to the previous-generation “Volta” architecture. Turing GPUs began shipping in late 2018.

Important features available in the “Turing” GPU architecture include:

New RT Ray Tracing Cores for the first realtime ray-tracing performance
Evolved Deep Learning performance with over 130 Tensor TFLOPS (training) and and 500 TOPS Int4 (inference) throughput
NVLink 2.0 between GPUs—when optional NVLink bridges are added—supporting up to 2 bricks and up to 100GB/sec bidirectional bandwidth
New GDDR6 Memory with a substantial improvement in memory performance compared to previous-generation GPUs.
