Eevee is fast you said? A 20sec render done with the upcoming E-Cycles, using the new Intel denoiser node, much faster preprocessing time and now about 3x faster render thanks to new optimizations 
You can now get E-Cycles as monthly membership or perpetual + 1 year of support, and get:
- cleaner renders at same spp,
- automatic tile size
- much faster rendering
- and the new Intel OpenImageDenoise node
