    i7 vs. E5 Xeon

    rlr29711 Community Member

      Hello,

       

      I'm putting together a build for a workstation and am trying to determine the benefits of going with Xeon vs.  i7.  Below are the builds I am looking at   Just as a note, I am switching from Mac and am attempting to build a 'Mac Pro' equivalent :

       

      1 E5-2687w 3.1 Ghz (scale up to 2 down the line) 8 cores (16 if two)

       

      2x E5-2640 2.5 Ghz 12 cores

       

      1 i7 3930k 3.2 Ghz 6 cores

       

      I'll be using the following software packages: Avid, After Effects, Resolve, Maya Creation Suite.  I think my biggest concern are rendering and compression times, as well as ability to grade in Resolve.

       

      Thanks for the help! Let me know if you need more information.

          First question: What is your budget for the system, excluding monitors and keyboard?

           

          a. $ 5 - 6 K

           

          b. $ 10+ K

           

          If a., then i7-3930K, if b., then 2 E5-2687W. I would definitely bypass 2 x E5-2640 and 1 E5-2687W.

            My intial budget is 6-7k.  Here are the other key elements of the build:

             

            1x120gb SSD (OS/APPs)

            2-4x2TB Barracuda XT

            64GB ram (1333 or 1600, not sure how much speed matters with this much RAM)

            RAID Controller (Looking for suggestions)

            Quadro 4000 or Quadro 5000 (Any ideas how soon Kepler refreshes are coming?)

             

            Why not the 1 E5 2687W?

              thats easy to answer

              the single Xeon is slower than the others and cant OC.

                I see.  How stable is overclocking a processor and is it safe to push it all the way to 4.5GHz over the long term?  I was considering the E5 2687w as an investment that I can scale up overtime - that's the only reason I am considering it.  I was looking at the i7 and was assuming the .1 GHz of a loss was negligible (assuming I didn't OC)

                  Forget about the Quadro range. Underspecced, underperforming and overpriced. Go for a GTX 680.

                   

                  For a raid controller and the rest of the equipment, have a look at a new system I'm planning to build: Planning and building a new NLE system

                    OCing when done correctly is very stable. and yes 100% safe (again when done correctly)

                     

                    we have a dual Xeon setup here that i think is close to benchmarks time. Eric was out sick yesterday or we would have had #s by now

                     

                    in the past it always took the very higher end duals to catch up to or finally outperform a single processor OCed system

                    at more than 2x the cost plus last gen Xeons you could OC, this go round its not happening. (regardless of what EVGAs website says)

                     

                    in a non overclocked system the 8 core Xeon 3.1GHz might outperform the 3960? not sure let me extrapolate.

                     

                    the 2687 will turnbo to 3.4GHz (all cores)

                    the stock 3960 will turbo to 3.9GHz (all cores) so right off the 3960 will outperform despite the 2 less cores.

                     

                    X79 3.3 @ 3.9 GHz (stock turbo)

                    3 Layer - 31:47

                    4 Layer - 34:14

                     

                    E5 2670 @ 2.6 GHz  (turbos to 3.0GHz)

                    32GB  1600

                    570GTX 2.5GB

                    4  1Tb Sata 32 Meg Cache 600 Drives in 2 Raid 0 arrays

                    4 Layer - 40:41

                     

                    if we take the the numbers we have here. and do some math replacing the 2670 with the 2687s speed i come up with 35:53 still not beating the stock 3960. (used proportional math)

                     

                    lets try it by %

                     

                    3.4 is 14% faster than 3

                    2441 seconds x 14% -  i get 2075 seconds  34:35  still not faster.. and amounts really to a wash..

                     

                    $1000 vs $2000 processor and all this at stock.

                    $600 3930k @ 4.5GHz kills the Xeon line completely.

                     

                    Xeons have their place in Animation (serious animation not lower 3rds) not in Premier

                     

                    lastly +1 what Harm said Quadros are a complete waste of money
