    “Ryzen memory latency’s impact on weak 1080p gaming @ PC Perspective”.

    Ryzen CPUs substantially underperform in games because of the massive cross CCX latency. Frequent thread migration across CPU cores in addition to slow average L3 cache access times (because half of it is roughly 2 times slower to access) is what’s causing Ryzen to not perform optimally.

    Why did they release 2-CCX CPUs? What’s the point? Why not release single CCX properly clocked properly priced CPUs that would’ve performed better, especially in gaming, and cost them less to fabricate. Most modern games are console ports designed to run on their 8-core JAguar CPUs.
    Why do they have to screw it all up every time.

      Does this mean some of the single CCX R5 CPUs will outperform the R7s in some cases? I haven’t seen any evidence of that.

        • Redocbew

        There are no Ryzen 5 CPUs that use a single CCX. The six core chips use a 3×3 layout and the four core chips are 2×2.

      No it doesn’t. It’s been proved that CCX latency has little to no performance impact.

        Other sources are showing a different story. In this video for example the poster is using a draw call benchmark. His run span across 2 threads running in one CCX vs two CCXs. The difference is a staggering ~22% better performance if you confine the two threads to one CCX.

          Benchmarks aren’t games.

          Especially benches that stress one specific workload quite bit more than you’d normally expect to see in a real world game.

          As far as CCX latency performance issues and games go that was mostly addressed by the recent power state update for Ryzen.

          At this point CPU performance differences between Intel’s Kabylake or Skylake and Zen are part IPC (Kaby/Skylake have a ~9% advantage there) and part clockspeed differences (Kaby/Skylake both will clock higher than Zen).

            Cross CCX latency is causing Ryzen CPUs to underperform in both games and other applications. Also, it’s worth mentioning that when compared clock to clock, the 1500X is roughly as fast the 7700K in general tests, both clocked at 3.5GHz. It’s only in gaming tests that the 1500X starts doing quite badly against the 7700K.

            False, all you’ve come up with is a draw call benchmark. As shown in the video linked above it proves you are wrong unless you can provide data to show otherwise.

            AMD themselves recommend buying high frequency RAM, even for their “budget” quad and hexa core CPUs. They won’t tell you why but we know now that high frequency RAM reduces cross CCX latency by quite a bit, which in turn results in performance improvements of up to 20% in games and other applications. I think 7zip runs +15% faster on the 1500X with 3200MHz RAM over 2400MHz RAM.

            The i7-7700K must have massive cross-CCX latency problems then, because as measured by this very site it performs 22% faster in games (fps) when you use faster RAM:
            [url<]https://techreport.com/review/31179/intel-core-i7-7700k-kaby-lake-cpu-reviewed/11[/url<] It doesn't really have cross-CCX problems though, does it? Games and certain other types of software just do better faster with faster RAM, that's the reason why AMD recommend it. As for the PcPer article, yes, the cross CCX latency is 111ns with faster RAM, and around 42ns for non-CCX inter CPU latency. But did you see where they looked at the 5960X, it's latency is around the 79ns mark: [url<]https://www.pcper.com/reviews/Processors/AMD-Ryzen-and-Windows-10-Scheduler-No-Silver-Bullet[/url<]

          That’s a lot bigger of a penalty than we’ve seen pretty much everywhere else. What I think you should take away from that is just that there is a penalty, but I wouldn’t expect it to take away nearly a quarter of the expected performance across the board.

      I believe the Windows Ryzen patch and faster ram do make a significant different in performance in despite of CCX and L3 cache latency/bandwidth issues. Check out this vid

    “The Witcher is coming to Netflix”
    I would watch the hell out of that.

      I mean, I would too because i’m a big CDPR fanboi, but holy crap people have a habit of screwing up video game screenplays. Let’s hope there is enough talent to make it good.

        • Redocbew
        • 2 years ago

        They’ve done a pretty good job with the MCU stuff so far, so I’m thinking that’s reason to be cautiously optimistic.

          • DancinJack

          Yeah, but for every one of those there is also a Warcraft the movie.
