X79 vs X99

[Huginn]

I'm curious. What would be the difference between a X99 mobo + 5820k and a LGA 2011 with an i7 4930k? 

I know X99 can support DDR4, but would there be a big difference in performance between these two chips? Or is it not really possible to predict this at this point?

If the difference would be minimal, I'm tempted to buy a LGA2011 if prices would drop (a lot).

 

Edited title. Silly op was silly.

[Askew]

X99 is LGA2011

 

X99 is LGA2011-3

 

X79 is the old chipset (LGA2011), X99 is the new one, (LGA2011-3)

[Excon]

X99 is LGA2011

X99 is 2011-3, theres a difference

[whatthe_fuzz]

X99 is the platform. The socket is LGA 2011.

 

X79 is also socket 2011 

[LukaP]

X99 is LGA2011

actually 2011v3

 

OP, difference is if you know what you need. x99 has more storage options than x79. also, haswell is some 5% faster clock for clock than ivy. and the 5820k has less PCIe lanes

Not a physical one.

Like askew wrote "X99 is LGA2011" it's a new socket revision. The X79 platform was 2011-0 now it's X99 2011-3.

 

5820K is going to be like a 4930K but with less PCI-E Gen3 lanes, ofc supports DDR4 (with the heavy expense) both are K'ingsley series i7 so overclocking is a go-go thing & tdp slightly higher but has a way lower wattage output.

@Askew @LukaP @ Edited the title. Silly op was silly :'(

But aside of the mobo, would there be a massive difference between the two chips I mentioned?

The only difference is that 2011-3 has a tiny change in the socket area so that you cannot use X79 stuff in it.

 

that and the chipset details for X79, look at it, same amount of pins, same layout on the pins, intel could have allowed you to use your old X79 stuff but no, that would've been too nice.

[LukaP]

Not a physical one.

actally the pins arent in the same places, so even physically its different

[Excon]

Not a physical one.

Yes a physical one.

show me

[LukaP]

show me

check left bottom corner on ivy EP and haswell EP, they use the same sockets iirc

 

[Excon]

show me

Hold down bracket is different for starters, also its speculation but pin placement is different

OK if the image is genuine I stand corrected good job.

Yes a physical one. The wiring is different and Intel has confirmed this. If you try to put a 4960x in a 2011-3 socket it will light up light a dry christmas tree in the Sahara desert.

[AMICLG]

X99 is LGA2011

 

X79 is the old chipset, X99 is the new one.

X99 is also LGA 2011-3 meaning it's not backwards compatible with LGA 2011-2 (X79) and vice versa.

I have corrected it now, if you scrolled down you would have seen I had already been corrected.

NP, just thought I'd make sure everybody has the right info.

So basically they moved the die slightly and called it a new socket ?.

It's all about having the most efficient model of I/O to the various buses.

[LukaP]

they probably figured a way to put the pins there more effectively, using less copper in the die, less different connections, so faster links (PCIe, QPI, etc)

[Glenwing]

The difference isn't really a performance one.  X99 boards will have much more modern I/O though.  DDR4 for starters, but X79 did not have any native USB 3.0, and only two SATA 6Gbps ports.  Sadly no SATA Express but it looks like a lot of boards will add that with 3rd party controllers.

[Enderman]

x99 is for the newer architecture HSW-E chips which have improved performance per core over IVB-E

just like the 4770k is better than the 3770k

the 5930k is better than the 4930k

 

no info on performance yet, but it will definitely be noticeable.

And this is another reason why I'm sure LGA2011 will die with Skylake. SATA needs to die altogether. We need to kill the SATA bus except for 2 3Gbps ports for high-capacity spinning rust, and the other ports can be replaced by a new micro-PCIe connector so we don't lose overall expansion.
