> You can get the same machine with an i9 but not ECC memory or the Xeon and ECC. The desktop and workstation class Xeons are in direct competition with i9 processors in terms of raw performance, which is why Intel uses features like ECC to enforce product segmentation. This isn't the case for the low-end i3 and Pentium branded processors, because the Xeon lineup simply doesn't extend down that far. If you want to build eg. an industrial PC with ECC memory but you only need a low-end CPU, Intel's official solution is for you to get an i3 or Pentium processor because they don't have anything equivalent under the Xeon branding.
