Hmm, I thought I was done with collecting GPU architectures and could move on to cloud computing in 2019 for further development, but it did not work out, meanwhile you have to talk through the sales department of all big cloud players before you get access to their GPUs, and, mostly they offer only Nvidia server brands to rent, no AMD, no Intel. Hence I did set up a lil Maschina again for GPGPU development. Intel i5-6500 (Skylake 14nm with AVX2 from 2015) with HD 530 graphics, Nvidia GeForce GTX 750 (Maxwell arch) and have yet to purchase some AMD GCN, maybe an used Radeon HD 7750 or even HD 8570. These are all outdated and low-end GPUs, but meanwhile I have enough benchmarks to inter/extrapolate Zeta's performance across different models and architectures, I just need some entry-level hardware to test some ideas, it should then scale up on newer and bigger models...
