Dual CPU Bottleneck ??? How to calculate it

[CloudX99]

Hi

I was wondering about the bottleneck on dual cpu , How to calculate it for example I want to buy some old dual socket x58 mobo and buying a gtx 1080 ti with dual Xeon X5680 but i tried to calculate the bottleneck on (The Bottlenecker) website but there is no option to choose CPU count so I’m confused now and waiting before buying this gaming and rendering setup

you can't calculate a bottleneck. only quantify relative performance with data you collect yourself.

 

Any online calculator for bottlenecks is bogus, and PSUs as well.

Trying to figure in-game bottlenecking for both CPUs doesn't really matter. Not many games will use more than one of the X5680s, and even if they do, they won't benefit from them.

 

Single-core performance is in the realm of AMD's FX CPUs. In all likelihood, this will heavily limit gaming performance when compared to modern CPUs like a Core i7-9700K. If multi-core performance in Cinebench R15 is any indicator, the system will also only render about as well as a Ryzen 5 2600X.

There's also the issue that this setup is not ideal for gaming unless you make provisions to isolate the game to one processor or the other. Games can be sensitive to data locality, which is an issue with Threadripper and why it has/had a Game Mode to begin with (https://www.anandtech.com/show/11726/retesting-amd-ryzen-threadrippers-game-mode-halving-cores-for-more-performance/16)

 

Basically it's not a good idea to use a multi-processor system for gaming.

You will likely run into some bottleneck issues with highly single thread dependent games since the CPU isn't particularly fast in that area, and you might run into issues with the dual cpu situation as well. It'd work fine for rendering though.

 

What's your budget? There might be newer/better options out there. I'd suggest taking a look at Ryzen. Lots of great options for reasonable amounts of money.

its going to bottleneck due to the relatively low IPC. you are better off trying to find a nice single socket x58 board and overclock the shit out of one of those chips. with a decent air cooler 4.5ghz should be achievable

also that board you have there has non standard connectors. looks like a z800 board. it will be more or less unusable inm a normal computer with a normal psu.
