    And the toy/gaming chipset for the Threadripper family seems to be explained by this:

    A 64-core CPU that can mount 256GB of RAM isn't a toy, and is completely pointless for gaming.

    The Threadripper Pro is literally an Epyc with a different name, feature set is 100% the same. There is no real benefit over buying an Epyc and a board for it.

    That said, the fact that they have not partnered with consumer motherboard OEMs and don't plan to do so (as said here https://www.anandtech.com/show/15910...-for-oems-only ), means this will be limited to prebuilt workstations like the Lenovo one, which is great for businnesses I guess.

    It's neat that it's available in multiple forms in a way to lower licensing costs of workstation software.

      Not sure if you misread or felt like hitting strawmen.

      I have never said the Threadripper processors are toys. I have said the chipset has a high focus on gaming and misses out a number of things important for workstations.

      And my post about the Threadripper Pro was about why AMD for some reason decided to made the previously released chipsets in a way that misses out for the workstation market.

        I'm saying it really isn't missing a whole lot for most workstations, and that it has no focus whatsoever on gaming, at any level.
        Also I'm confused by your mention of chipset. PCIe and RAM controllers and all "businness features" are in the Threadripper "CPU" thing, not in the chipset.

        That said, what does a Threadripper system offer to a gamer? It's beyond overkill in all parameters. Too much cores, too much RAM, too much PCIe lanes (SLI/CRossfire are dead and were dead years ago too, so there is no point for 4 PCIe slots), too much USB 3.0, too much SSD slots and storage ports.

        It is clearly aimed at workstations, but it cannot be used for high end ones because it does not have enough RAM. Does not make the other workstations any less workstation than high end ones.

        Oh I can tell you the reason they did this.
        Back then they didn't want to lose any bit of Epyc sales, square and simple. Since this "Threadripper pro" is clearly a rebadged Epyc, it's pretty much certain they were more interested in keeping all possible parts for their initial assault of the server market (which is the main moneymaker for these kinds of processors, no doubts about it).
        They provided a segmented product for the midrange workstation and enthusiast, (Threadripper) but went to great lengths to keep it NOT APPEALING for server use.

        Now, a couple of years later and in a much better position than back then, they feel like they can afford to not 100% target servers only with their high end CPUs and make these vanity products (that still drive sales, but aren't main moneymakers themselves).

          The memory controller is in-package - not in the chipset. Still, I wonder if that die isn't really the same one that's also used in Epyc.

            you mean "IO chiplet"? Because it really probably is using the same IO chiplet as Epyc given it has the same features. I mean it's either that or they made a new one that does the same job, which is kind of weird.

            • I moved up to an i7 recently and I was very disappointed with the performance -- it's not slow but it's just not fast. Intel got lazy and it shows. Now AMD is eating their lunch in the desktop market while ARM is taking up the mobile market. Intel better get their act together or they will get left behind for good.

                From what to what? "i7" means different things, depending on the market and generation.

                Have you tried disabling mitigations? Depending on what you do with your PC, this could be worth the risk and provide an easy performance boost.

                  I had a Core 2 Duo, and I loved that thing. It was miles ahead of the Pentium 4 it replaced (despite the P4 having a primitive form of hyper-threading, lol). Remember when single-core computers used to hang and you couldn't move the mouse for a minute? Dual cores wiped that out for good. Anyway, it lasted nearly 10 years before I got an i-7. I'm sure disabling the mitigations would speed things up, but personally, I wouldn't trade security for speed. I guess it's just because I waited 10 years from the dual core processor that I expected things to get much better. It also didn't help that my CPU was nerfed after I bought it. It's enough to sour me on x86 processors in general. I'd love to see ARM take over.

                    Yeah, they were good.

                    Except, I was more interested in what you upgraded to.

                    Out-of-order ARM cores were affected by some of the side-channel attacks, too.

                    I'm with you on wanting to see the sun set on x86, but it really is the fastest thing currently available. Apple's ARM cores are the only real challenger, but only in a power-constrained or thermally-limited scenario. If you put them in a desktop or a performance-oriented notebook, the higher clockspeed ceiling of x86 will carry it to an easy victory.

                      i7-6700. It's nice, but it doesn't feel as big of a jump as the Core 2 Duo was from the P4. Don't get me wrong, I'm happy with what I've got; I just think the industry didn't move as much as it could have.

                      Apple is making the move at the right time. Intel is still struggling to shrink their die while ARM is rapidly gaining performance. I was watching a recent video of the new Raspberry Pi 4 and I was impressed with how far they've come along. I really think the majority of computer users (let's face it, most of them are consumers rather than producers) will be completely happy on a new ARM board within the next 2-5 years, which is how long Apple is planning to take to release their new ARM-based Macs.
