OK, I don't plan to defend Intel pathetic product segmentation, but X299 is not a bad deal if you need lanes, but not cores. Get 10 core model + decent board and you can still plug 3 VGAs for full bananas rendering machine.
Nobody in right frame of mind doing rendering on CPU only, except niche things which don't support things like CUDA. Blender is perfect example. Especially with advanced lighting CPUs are just lame option to render anything. You pick CUDA render and Blender flies! I'm certain new 3xxx TR won't solve the problems of rendering machines. CPUs are inherently inferior to VGAs at rendering speed, by laaarge factor.
In DAZ I made once experiment with a scene which rendered for nearly 31 hours on 2 1080Ti alone. And then re-rendered everything with OC TR1920x added to the mix. Render finished 58! seconds sooner. That's hopelessness of CPU rendering ladies and gentlemen. You waste 300W of power every hour for all 58 seconds over day and a half.
Recommending 2nd gen TR over 109xx is ludicrous. Only if you need every single lane of TR, X299 pull this ahead. Memory latency is horrendous on 1xxx and 2xxx TR. Not good for gaming, not good for rendering or visualization dependent on memory speed - e.g. particle physics.
And if author(s) of this comparison thinks that AMD will discount 3xxx series TR any time soon then good luck. Corporation AMD is doing now full-Intel. They'll milk and bloody squeeze the balls of everybody who want them. I can see many retailers in Europe just going bananas with TR3xxx pricing. Even my most pessimistic estimates were smashed to bits. Couldn't care less... getting Acer Concept D7 for another 2080 RTX rendering machine.
