    It sounds like you're getting the models confused. The Opterons in this benchmark are K10's which were performance competitive with Xeon in their day. After the K10's came a completely new architecture - the Bulldozer architecture (fam 15h) which used the much maligned CMT cores. Bulldozer remained essentially the same for three generations, and was never truly competitive with Xeon.

    Again, the K10 Opterons used in this article are a completely different architecture from the more recent Bulldozer models, and the very newest Zen is another completely different architecture.

    ^ This is like comparing Threadripper with a Core 2 Duo, and saying "Holy crap I didn't know Core 2 Duo sucked that hard. No wonder intel wasn't making any money at all."

      Aha! So there's the confusion, I was under the impression these were first-gen Bulldozers. My bad.

          There are no excavator-based Opterons. The last ones before Zen are Piledriver-based (2012).

            What about a FX-8300?

              No!
              There are all the missing Bulldozer-based between the Opteron 2XXX and Epyc.

                I don't know if it's worth it... +30W to TDP... It's on an edge.

                The FX-8350 on my desktop runs quite hot. From that experience I'd want to keep TDPs under 100W, which FX-8300 is barely.
                Fans would propably get quite loud at full load. I'll consider. Thanks.

                  +700 MHz Base clock, +600 MHz Turbo clock, for me it would be worth it.

                  ... The FX-8350 on my desktop runs quite hot.
                  The FX-8350 has a TDP of 125 W. Another +30 W.

                  From that experience I'd want to keep TDPs under 100W, which FX-8300 is barely.
                  95 W is under 100 W.

                  It depends on the cooler. I am using a Noctua NH-C14S and I can't hear it even at full load.

                    Well.. My server is in 4U rack case. That in turn is in a rack cabinet with a windowed door. There's no space for anything big, so I must keep the temps down as I want it to be quiet. I like I said 95W is quite high. But I could buy one (used maybe) and test out if I can keep it quiet.

                      Racks have a lot of very loud fans.

                      4U is 7" or 178 mm.
                      The height (with fan installed underneath the fins) of the Noctua cooler is 115 mm.

                      I doubt you will have space problems.

                      Even if you have space problems, there are enough other quiet coolers up to 80 mm:

                      So no excuse to not send Michael your CPU.
