i7 6700k vs SLI

[ashy]

Hi , 

 

I would like to find about your opinion on this topic.

 

will a i7 6700k ( 16 PCIe lanes ) will bottleneck 2x Titan X cards in SLI?

 

my rig is : 

MB: ROG-MAXIMUS-VIII-HERO-ALPHA

CPU: i7 6700k

GPU: 1x EVGA GeForce GTX Titan X SC

2nd GPU: EVGA GeForce GTX Titan X SC is not yet installed ( I am missing the SLI bridge proper length connectors ) 

 

Regards,

Valentin

if a 6700k will neck them, there's not much more to be done to stop necking either way.

6700k is the best CPU out right now. 8x each will not bottleneck them, but if it did--it's like 1 game out of a 100.

Best CPU?

If you are going for dual Titan X please tell me you have 2+ 4k screens.

In terms of pure CPU performance single core.  Unless the 5.0ghz Skylake Xeon came out.  Most games aren't CPU bound.  So, in terms of CPU's and IPC -- it's the best there is right now until Kaby-lake.

Single core, yes. I sort of want one to play with it... I just don't want to put the money down. Saving for a 2nd Titan X.

Ok Titan X are a waste of money when a 980ti can be had for 60% of the cost. And no a 6700k will not bottleneck 2x titan or 2x 980ti

No it isn't, especially once DX12 takes off and cores > core speed (within reason). Yes you are correct single core IPC at standard clocks, but there is very few single core apps now.

2x Titan X wont power 2x 4k screens. Yes in a lot of current games, but most of the newer more demanding (badly optimised) games, they wont cut it, not at good settings and good FPS anyway

Or at least one? They would be able to power them if AAA companies really cared about their customers (*Cough* Ubisoft *Cough*) But there are very few AAA Developers/Publishers that care about their player base, or at least for PC

[othertomperson]

Yes, there are some circumstances in which that, or any CPU, will bottleneck. I'm sure there are some situations at some low resolutions like 1080p where even that CPU will not be able to give you 144 fps, but your GPUs happily could.

[Brawndo]

Won't bottleneck, but do you need the 12GB VRAM?  If not, go 980 Ti.  my 2c

I was asking because each Titan X has a 16X PCIe bandwidth , where the CPU have a total max bandwidth of 16 PCIe lanes. Meaning that when in SLI , the Titan X card will both run at 8X.  Considering this I am still not sure that GPU's will be bottle-necked . Computing power wise , for sure not , but the PCIe bandwidth ??? maybe yes ??

 

I run this setup with a single 4K monitor.
