    i7 six-core vs Xeon six-core for AutoCAD Revit


      We currently have 6 PCs running Xeon Quad-Core for our Revit department.  Now, we need two more PCs for Revit department.  I would like to know which of these CPUs I should use i7 six-core or Xeon six-core.

          In our side-by-side testing of i7 Extreme and Xeon X5500 series systems on behalf of a long time client we discovered that the Xeon based system was always faster in rendering their currency trading charts (4-9 minutes on C2D E8xxx series with 4GB RAM on start up for baseline, ~2-3 minutes i7 Extreme with 8GB, and ~75-90 seconds with X5580 with 8GB).


          The app ran a primary thread as well as three additional secondary threads. So one core was always pinned while the other three moved about in utilization. A Hex-Core would provide room for additional OS threads and the like.


          All systems were configured with X25-M SSDs to render the I/O question moot.

          Where time is of the essence, meaning work faster = paid more, such as our currency trader we configure systems as follows:

          • Intel X5500 or X5600 series CPU
            • Unless the application is proven to use more than one or two threads 1 CPU is good.
          • Intel Workstation Board
          • 2x (two) 4GB 1333MHz ECC for 8GB
            • Or: 2x (two) 8GB 1333MHz ECC for 16GB
          • Intel RS2BL040 RAID + BBU
          • 2x (two) 160GB Intel X25-M Solid-State Drives


          The systems would be configured with a single parition plus the 100MB one that Win7 places at the front.
