By getting the 2990WX, I am taking a chance on the IO, 64 gig is plenty for what I do for memory. I know I can use all the cores, but what I don't know is what will be gimped. Thats why I am getting it, to tell you all what I find, and in my builders thread, I hope people suggest benchmarks that I can actually run to figure all of this out.PCIE 3.0 x16 Riser cables @ 200mm are about $25. @300mm $50. @600mm $65.
Fair enough.
If you could do a layout with 200mm cables, that'd only be about $200 more added on.
That and the I/O is literally cut in half from what you should be getting making the processor completely unbalanced.
I'd have to pay double what I paid for my 1950x while sitting with the same I/O. This is where I establish a no-go zone. The diminishing returns are too pronounced. It's funny because I got railed for this when I applied it to intel vs amd. However, clearly I am without bias as I can apply it to AMD's own processor line. 1950x/2950x is peak balance on this particular AMD HEDT platform in my opinion.
128GB of RAM limit is a joke at with such a core count when the EPYC processor of this core count supports a Terabyte of RAM with 16 dimm slots. 128 PCIE lanes vs 64 PCIE lanes.
That being said, I guess this is interesting because its a new architecture to consider. You have 2 dies w/ no direct I/O being fed by infinity fabric. You get double the amount of cores but no increase in I/O. I guess this will make sense to someone. I can't help but recognize though that the EPYC is $400 more and the mobo $200 more. If you're going to spend $1800 on a processor anyway... But then again you get higher clocks on RAM/Processor if you go with threadripper vs Eypc. So, if you don't care about I/O scaling much or a terabyte of ram capacity and you care more for ram/cpuclocks then this is your processor...
$1800 is nothing to sneeze at. I await 7nm
