Yes, that new algorithm disproportionally disadvantages AMD CPUs which are largely about multi-core performance. The new score weighting basically ignores the main advantages of the Ryzen series.

I'm curious if they're just catering to their most common readers. If they have a high percentage of people that use the site that use workloads where single-core performance or low-count-multi-core performance is most important (gaming, apps that take advantage of 4 cores but not 18, etc) then maybe they thought that their algorithm originally favored Ryzen too much, and this is a balancing correction, not a favoring of Intel? Also, I don't understand the uproar over one small little overall percentage number- the rest of the numbers are there for anyone to easily weigh one against the other. Just a few lines down it's clear than the 18-core part demolishes the 4-core part in multi-core workloads (as anyone would expect without even visiting the website in the first place). Being able to handle more programs at a time/etc really has no bearing on "effective speed"- if their workloads are not apps that take advantage of 18 cores (encoders, etc), it's possible a 4-core part could "feel" just as fast, or faster, than an 18-core part if it does their workload faster. That said, the whole AMD/Intel war is less important to me because fanboyism in any amount is toxic and worth avoiding. People biased heavily enough towards one company will always see anything like this as some kind of conspiracy or attack, regardless of whether or not it's true (something I don't know in this case)

  What do you most people use their computer for? Web browsing, word. Maybe some foto or video editing. With the exception of word all of these things MASSIVELY gain from having lots of cores. Not sure where the myth that most people have single threaded workloads comes from because it's not true at all at this time.

    I don't think its true that most people do web browsing. Its just an easy generalization to make. The world has thousands of industries and each specialty domain has their set of software suites that they need for their business. In my industry (pharma), and I'll adda caveat here that I haven't done a rigorous scientific analysis of every single workload, but off hand, all of our software is heavily dependent on single-thread perf. To be sure, there is some stuff that benefits from multiple cores.. dna sequencing/alignment/processing comes to mind, primarily because we're processing hundreds of GBs of data. But by and large, I would pick a CPU that has better single-thread perf. For our accounting folks who use quickbooks a lot, are not going to benefit "massively" from a high core count. For our facilities team that uses autocad.. again same thing .. I don't find a massive benefit from 10-12+ core systems. Sure you can always on a case-by-case basis invent scenarios which could potentially benefit from more cores, but this massive gain across the board that you claim is a bit of an exaggeration. IMHO/IME/YMMV/$0.02 etc..

      99% of single threaded industry software doesn't need more power. That's why all of these cheap office pc have i3 processors that are years old. Single threaded performance has only one real advantage at this time and that is gaming. I think multi threading performance is way more important in the real world.

        >99% of single threaded industry software doesn't need more power. Again, I don't know if that is true. I'd love to see stats on that. My gut tells me improved single-threaded perf will always be welcome in most software because most data transforms are not not easily parallelizable. Certainly for me, more single threaded perf is always welcome in all the software I use daily.. from office suites to compilers to IDEs to photoshop to soft-PLCs/SCADA/HMI or even when opening a super large excel file with crazy forumlas. I don't think its just gaming. The specifications of budget/cheap computers are not really an indicator of what will or wont benefit from single-threaded perf. Whether the benefit is worth paying for will obviously depend on other factors. For me its a nobrainer.
