    Paternity leave? What did I miss? I mean... congratulations?!
    Man, if you just got a father then take your time!

    Looking forward to benchmarks of these new CPU/APUs.
    But I am also still looking to see some Kabini-ish thing. (Something 4C/4T, some ASICs for media acceleration and 25 W TDP or below.) Those Athlons (2xx GE, 3000) are close and the price is fine, even some low end Ryzen 3 APU might fit, but still... But I guess they're focusing on serving the big things and mediums first, then maybe broadening the palette also towards smaller / embedded-capable CPU/APUs.

    plate = Obazda = tasty stuff, German-Bavarian / Czech specialty. A mixture mostly of cheese(s) and some spices.
    I also like it.
    Stop TCPA, stupid software patents and corrupt politicians!

      Considering that this is a pretty popular game that has this error pop up only on Zen2 chips, it's worth mentioning, as I think these problems might make someone think twice before buying an offending chip. I mean, this is still way better than Intel, but if it was not resolved, it would be a huge downside for me to pick up a Zen2 processor.

        I assume it might be possible to get down to 25W with undervolting and underclocking the chip. Considering that it's unlocked, it might be a matter of just tweaking it a little bit.

          better to buy the 3900x cpu, too expensive this one, onlyfor people who need specific workstations

            Congratulations on the new addition to the family Michael! We love the work you do for this site, I check it every day, but it is perfectly understandable if you need to spend time with family during this transition. We will still all be here when you return!

              Give it a rest. I really doubt that the majority of readers of Phoronix care about bugs in an old game, even though some may be gamers.

                Both have 128MB of L3 cache, so the difference is 24 cores * 512KB L2 cache vs 32 cores * 512KB L2 cache.

                Presumably the 100Mhz lower base clocks are due to needing to stay within TDP/power requirements with the extra 8 cores, so that's only likely to apply when all 32 cores are being stressed and you're getting the benefit of the extra cores anyway.

                And the infinity fabric doesn't change. They both have 4 CCD's, it's a 6x6x6x6 and a 8x8x8x8 setup.

                  It's useful on bandwidth-constrained situations, e.g., a truckload of cores being fed by dual-channel DDR4 SDRAM. They've taken other measures as well, like reducing bottlenecks in the fabric, but the cache isn't wasted silicon. The CPUs would surely perform worse if it was reduced or removed.

                    You can put in a couple of x16 GPUs, a couple of these Micron X100s, and 4x 100 Gbps Ethernet.

                      Threadripper 3 + T-rex 40 motherboard. Violence in naming = violence in computing? Is that the marketing idea? (And will we see dinosaurs on the boxes too?)
