Title: Terragen AVX2 / AVX-512 Support
Post by: D.A. Bentley (SuddenPlanet) on November 16, 2017, 01:37:08 PM
Does anyone know if the Terragen 4 rendering engine uses any of the AVX / AVX-512 CPU extensions found in Xeon CPUs, and some Core i9 CPUs?  I know the Ryzen Threadripper CPUs has a scaled back set of AVX extensions, and am curious if it would have any impact on TG4 rendering speed.

I know Vue Infinite takes advantage of AVX, and since I use both applications, although mostly Terragen, I am just planning for my next workstation, so any insight would be helpful.

The new Intel Core i9-7980XE (18-core) CPU is what I am looking at.  Although the Intel CPU is twice the cost of the amazing Threadripper 1950X, when considering the difference between a $6k machine to a $7k machine it doesn't seem all that significant.

Yes it does in some places, but I don't know how significant it is to render times. I trust real world benchmarks before all else.
