    Having to disable half of your CPU to *gain*performance is nothing short of a clusterfuck IMO.

      Is there a setting somewhere to hide posts by users of my choice? A blocklist. I've seen such features on other forums, it is quite a useful feature. I'll have another look in the settings but haven't spotted it yet. Thanks.

            If you give it enough time (10 min maybe?) firefox completes the webpage loading.
            It's loading almost instantly here in Kyiv

              What users expect from a CPU is that it runs all of their software well and not just some of it. These benchmarks show one has to look much closer with Alder Lake than before and one is possibly forced to tweak BIOS settings on Alder Lake systems in order to get the most out of them.

              This is definitely not what users want. Geeks and nerds may enjoy experimenting with BIOS settings, but the majority of users and developers expect that it just works and that it does so well. So yes, it is a mess Intel has created here, and it is left to others to sort it out.
              The article clearly shows the best perf and best perf/watt was achieved using the stock configuration. Doesn’t seem to indicate anything is a mess to me. (If you’re gonna comment on an article the least you can do is read it).

While there might be some performance left on the table due to suboptimalscheduling, I wonder if a chip with, say, 12 P-cores wouldn't be a better design than this hybrid mess. It probably wouldn't use much more power that 8P+8E chip, it wouldn't need all kinds of software trickery to work properly and AVX-512 would work out of the box. And considering that Sapphire Rapids will have no E-cores, it'd clearly be doable. I get it that Intel needs something to compete against ARM in the mobile segment but this hybrid core idea looks like a step in the Itanium direction. It *might* be more interesting in laptops.
                I wonder this as well. The scheduler issues are significant though. Look at the average power consumption for the two scenarios. P only was 50% more power. That’s significant enough to make me hesitant to compare the performance. Also keep in mind intel said that one P core has the same size as 4(!) E cores

                  I tried setting that before for someone, and unfortunately it didn't work. I'm wondering if it might just be for private messages or something.

                    No, look again. The benchmarks show the opposite. Several of these show clearly that one gains performance by disabling the 8 E cores.

                      This is a known issue with vBulletin - for some users it works, for others it doesn't. I've asked Michael to migrate to something a little bit better maintained, e.g. XenForo, but he declined.
