Xeon W5990 vs. 3rd Gen i7 for AutoCad

Hello,

I have a free Xeon W5590 3.33GHz CPU and am wondering if I should build an AutoCad rig with that, or if it would be better to use a i7-3770K Ivy Bridge 3.5GHz (3.9GHz Turbo).

The goal is the fastest rig at the lowest cost.

The variable costs would be the mobo and RAM which are probably going to cost more with the W5990 eliminating the cost savings of the free CPU.

So is the i7 faster than the W5990 for AutoCAD, or will the performance be similar?

  1. I can't find any technical specs of that CPU, can you give a link?
  2. It's a 5590, not 5990. They made a typo.
  3. getochkn is right! Sorry.

    The Xeon needs twice the power, probably more heat, no SSE instruction set.

    I would sell the Xeon and probably be able to fund part of an I7 rig from it. lol. There isn't any real benefit from it unless you had 2 Xeons and could get a dual cpu board, then it would have an advantage.
  5. getochkn, that is what I was thinking too. If I did the 2 Xeon's then the performance would certainly be better, but would it render drawings twice as fast?
  6. Yes of course, rendering relies mainly on the CPU power, it will surely render better than a single CPU. Xeons are more intended for intensive workstations work.
  7. Ok. So it seems like if I want to purchase a second Xeon and RAM then build that rig. Otherwise do the i7. Thanks!

  9. the xeon is fine. got 4cores+4ht cores. would make no sense to buy a 3770k.

    Thanks for clearing that up. You earn the runner up award!

    I agree that the performance would be similar. It is going to come down to how much a single CPU mobo costs for each version, then the cost of RAM (ECC vs non-ECC).

    I need to price it out to see if the cost savings is erased. If it turns out to be the same cost for each build and I only opt for 1 CPU, wouldn't it make sense to buy the i7 (newer, overclock capabilities, HD4000)?
  12. ur still gonna be spending money for nothing. gonna need a 3770k=320$+good mobo=250$+ram=160$

    whynot utilise your free cpu.

    just an idea.
  13. well in single cpu situation both be close. but if your gonna need 2xcpus xeon wins here.
