5820k vs 5930k?

Other then the base clock can someone explain the diffrence between these 2 cpus I would imagine that's there has to be more to it then clock speed for the 150$ price diffrence but don't understand enough to know what

number of pci-e lanes

28 vs 40

[Tech_Dreamer]

5930 has higher CPU frequency, Better overclock speed & pcie lane difference but that is if you try to go quad

[Glenwing]

It has more PCIe lanes, which is important if you want to run 4-way graphics cards. Other than that, no difference.

How do pci e lanes effect me? I'm pretty new to this so thanks for the help

basically you can add more ssd's and videocards and other stuff to the system

 

most people only need the 5820 tho

Well I was hoping to invest in a new Intel 750 series and 2 way sli on gpu so can I save the money and go with the cheaper cpu? Or would I be better off getting the 5930

Right now you'd be fine on the 5820k. You could run 2 GPUs in PCIe 8X for 16 lanes together and the 750 SSD with 4x lanes; total would be 20 which is under the 28 limit for the 5820k.

 

Once GPUs start requiring PCIe 16X then you'd be limited to only 1 GPU tho.

 

On a different note I would highly advise against SLI, you are better off just getting a 980 Ti or a Titan X and OCing instead.

So it there a limit I can run these things at for example could I get one graphic card and one ssd and run them both at 20 and get better performance? Also if anyone knows of a video I can watch about pci e lanes that would be awesome

[bomerr]

pcie lanes = bandwidth; it's the max amount of data that can be transferred.

 

each device needs a certain amount of bandwidth to not bottleneck. GPUs need more bandwidth than SSDs so they are rated for a higher amount of pci-e lanes. You can't run a device with more lanes than it's rated and even if you could there would not be any gainz as they device itself determines performance.

 

all you need to know right now is that GPUs use PCIe 3.0 8X worth of bandwidth, they are rated for 16X tho so there is future capacity to grow into. 

 

oh and PCIe 3.0 8X = PCIe 2.0 16X.

That's helps me out a bunch thanks so much for the help guys I think I got it
