He is a bit of a knob sometimes, his original Threadripper review was cringe worthy, he spent half on the review with that weird grin of disdain on his face snarling and sniggering at the amount of cores and PCIe lanes it had, using old AMD "just add cores" jokes, his answer in that review was "This is unnecessary because of CUDA" he must have said "CUDA" three times more than he said AMD and Threadripper.
The last video he did with JayZ2cents where they were comparing their reviews because they had been getting a lot of "feedback" from the community at the huge performance results differences between their Ryzen 3000 results, in that JayZ2Cents were much better he did the same thing again, he could not bring himself to talk about the multithreading performance of the 3900X and instead his answer to everything was "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA" "CUDA"
He hates high core count CPU's, hates them., its because they threaten the usefulness of his precious CUDA, something else that's on AMD's targeting radar.
The guys a #### head.
You know what, i'll expand on this.... in 2D/3D render applications you can render the scene out with either the GPU or CPU (CUDA / OpenCL) GPU is generally faster, however there are limitations, once a scene gets to a certain size the GPU, let's say a Quadro GP 100 16GB cannot render the Scene if it's more than 16GB, because that's all the GPU has.
Right so now take a 2950X with 32GB of RAM, that's plenty of RAM to render the scene, what's more the 2950X will do it about 80% as fast as the Quadro GP 100, which is a £6000 GPU.
This is why Threadripper sells so well, it is a rendering monster and it's fast making CUDA obsolete for this type of workload and from what i have seen from Steve at GN he hates that fact, i don't know why but he's got a strange fixation to GPU hardware acceleration, AMD's high core count HEDT CPU's are making nVidia's thousands of £'s Workstation card's obsolete.
I don't use CUDA in Blender, i use the CPU.
