  • Weird they didn't talk about the DDR4->DDR5 transition. The 5800X3d->7800X3D went from DDR4->DDR5.

    DDR5 is literally twice the price per GB. It's better for sure, higher bandwidth but waaaay more expensive. The 9800X3D supports much faster and even more expensive DDR5 than the 7800X3D too (DDR5-2667 to DDR5-5600).

  • The x86 architecture still going strong. I've always though Ryzen was a fitting name, AMD had Ryzen from the ashes and struck a blow to the long dominant Intel.

  • The AMD Ryzen 9 9950X3D / EPYC 4585PX is a beast for 99% of compute workloads.

    It has the highest base clock of any modern AMD chip (4.3 GHz), plus 16-cores, which is already more than most workloads need.

    Can’t wait to see what Zen 6 brings early next year. Rumors say 24-cores and another big jump in single-core performance.

  • 2 years sounds very fast. It seems to be because the 3d cache SKUs of each generation were released at different stages. The Zen 3 one was a later variant.

    First zen 3 November 5, 2020 with desktop processors. First desktop Ryzen 9000 processors on August 8, 2024. So the generations were about 4 years apart.

  • Compound this with Linux users seeing a ~8% gain (and some very big gains here and there) on performance from ongoing kernel improvements too! https://www.phoronix.com/review/linux-618-73-amd-epyc

    This only goes back one year, to Linux 6.18. Wins would be even bigger if we go back another year. Also, this isn't tracking any of the rest of the improvements in userland: it's just the kernel. Some newer GCC, and upcoming new x86-64v3 targets will all have some pretty nice wins too.

    Great days to be on open source. And it only ever gets better.

  • I suspect the improvements are even more dramatic going from Zen 1 through to Zen 5. AMD has really hit the jackpot with how scalable the Ryzen CPU is considering how they're able to improve the performance from year to year. This is a stark difference to the FX series during the 2010s, which saw very small YoY performance increases by comparison. Ryzen really is AMD's equivalent to what Nehalem/Core was for Intel back in the mid 2000s.

  • I Picked a threadripper for a box that needed a lot of IO and figured that with that many PCI lanes I couldn't go wrong. But I have to admit I've been more than pleasantly surprised by the performance of the CPU as well, it - easily - outperforms all of the XEON and I7 based boxes that I have. The only thing I wished I would have done different is to max it out with 256G DIMMs when they weren't the price of a car.

  • I was recently able to get a workload of mine optimized enough on Zen 5 to hit a sustained 6.0 IPC/core (3.0 / thread) at 5.1 GHz. Seeing the a > 99.8% branch prediction rate and a > 99.99% L2 cache hit rate retiring > 1T instructions every 3 seconds feels amazing.

    Zen5 is incredible when you're able to make the most of it. I’m super excited about Zen6.
