Xeon E5 2699 v4 Bottleneck a 1070?

+1 James.

That's definitely not going to be a strong gaming CPU. Its designed for distributed processing environments like virtualization in the data center or video encoding/rendering.

It'll do the job, at 1920x1080 but you'll definitely lose FPS because of that CPU vs a stronger gaming CPU. You need a much stronger single core performance. If I had to guess though you'd be well over 60FPS if that helps your decision.
 
Not exactly. The E5 can turbo up to 3.6GHz on a single core, which will compensate for its low clockspeed across the cores. As long as you have turbo boost on it should not bottleneck it. However, I do not recommend this CPU for gaming if that's what you are planning on doing with it.
 


Yeah, that's for only a single core though, so it'd perform like a single core CPU in that case.
But if it starts to get any higher than 1 thread, which most games will do more than single threaded, it'll drop down to 2.8ghz.

That's still quite a lot slower any normal Intel or AMD desktop CPU.
 


My job at intel gave me an opportunity to get one for free and build it into a system and I took it
 


Shoulda asked for the 8700k than 😛

Or one the extreme series CPUs.

Just because intel overprices their highest end CPUs doesn't mean they're actually worth that much.
 


I didn't have a choice on what type it was the Xeon or nothing.
 


So is it a bottleneck like the specialists here supposed ? - Because I doubt that. Modern games like Witcher 3 do support multicore. DX12 does support multicore better that DX12 (they say so).

 
Agreed. If a game is not properly coded for multicore, such a low clocked CPU could be a bottleneck. The single-core performance of such a cpu is then relevant. Don't know how good this E5 is. I would play Chess with it, I think that's a good game for multicore ;-)
