    E5504 x E5420

    kleber.leal

      Hi all,

       

      I want to compare two processors: E5504 and E5420.

      Searching on the web i found the cpubenchmark.net. On this site, the E5420 model is better then E5504. This is correct? The E5420 get 7854 score, while the E5504 get only 6256, or 20% less. The E5504 should not be more performatic?

       

      Waiting for resposnses.

       

      Thanks for all.

          Hi there,

           

          The E5504 processor can be the better one here but one thing you should remember is that these two processors use completely different technology. The E5420 is a normal quad core processor whereas the E5504 is one processor from the new series of processors for servers, that is the Nehalem processors, similar to the i7 processors on the desktop side. They have different architecture and also have the memory controller built in the processor itself.

           

          Hence to use the E5504 processors you require the new series of server boards.

           

          In general, all the new series processors from intel, performs better that the previous series, however you have to determine what type of processor you require based on your needs.

           

          Hope this info will be helpful to you.

           

          Cheers

            I'd agree with the benchmarks you saw, the E5504 whilest being newer is clocked lower and has less cache, the newer architecture just can't make up for it.

             

            However if you compaired an E5520 vs E5420 then you'd see the new architecture shine.

              Hi, I have to make a purchase/deployment decision.  Which will be better for a SQL Server, 2xE5420 or 1xE5520?


              Thanks.

                I'd got with the E5520 assuming the system is a dual socket system, this gives you and easy upgrade path.
