Besides the new GeForce RTX 2080 series being attractive for developers wanting to make use of new technologies like RTX/ray-tracing, mesh shaders, and DLSS (Deep Learning Super Sampling), CUDA and OpenCL benchmarking so far on the GeForce RTX 2080 Ti is yielding impressive performance -- even outside of the obvious AI / deep learning potential workloads with the Turing tensor cores. Here are some benchmarks looking at the OpenCL/CUDA performance on the high-end Maxwell, Pascal, and Turing cards as well as an AMD Radeon RX Vega 64 for reference. System power consumption, performance-per-Watt, and performance-per-dollar metrics also round out this latest Ubuntu Linux GPU compute comparison.
