    Now that there is confirmation that AVX-512 works when the E-cores are disabled, I'd love to see a few test runs with AVX-512 workloads if your motherboard lets you get to a configuration where AVX-512 works.

      You neither know Intel nor Monsanto, or you would not ever compare them to one another.

      I prefer AMD myself, but I can still appreciate how much Intel has done and still is doing for the industry, an industry they helped to create and shape in significant ways. And Intel allows for competition while others in the IT industry did everything they could to destroy theirs.

      Monsanto however is a whole different class of evil... One, who thinks they can do no evil. They are like a teenager with a planet-size chemistry set, who has never heard of the word "side-effect".

        I am really glad to see Intel has taken a big step forward and is again pretty competitive with AMD's offerings. The best possible outcome is that every year the performance leader changes, fierce competition is great for the consumer.

          As well under the PlaidML machine learning software was a good showing for Alder Lake

            Thread Director is one of Intel's hyped ~Technologies~. The Linux way of dealing with heterogenous CPUs is for the plaform/device tree/etc. to inform the kernel of the "capacity" of each core. I wonder if that's plumbed up for Alder Lake?

              The point is that instead of using a 40 P core processor you could use a 160 E core processor in the same die area but with 40% less power consumption.

                A bold statement considering the many times Intel lost in court over anti-competitive practices (and had to pay billions to AMD). They seem to only allow competition from AMD up to a certain point, basically allowing them to be a deterrent for antitrust investigations from governments. The situation has changed a bit lately with the advent of ARM in more markets and the general lack of antitrust action from governments (when compared for example to the 90's).

                  Speaking of p- vs e-cores, here's in depth coverage from computerbase.de:

                  It's quite dense German text but Google Translate probably can manage it.

                    Good showing and in desperate need of a "tock" (bring back the "tock")

                      While Alder Lake seems to be a great step forward for Intel, from a consumer perspective, Raptor Lake should be even more appealing. At least I expect them to solve the AVX-512 dilemma with their new Thread Scheduler with that iteration, maybe they fine tune their 10 nm process a bit further and fix a couple of other architecture bugs. By then I also expect DDR5-pricing to be more sane.
