AMD Zen 2 aka Ryzen 3000 CPUs details
  • 88 Replies sorted by
  • The Rome processor will have up to eight core chiplets, for a total of 64 cores and 128 threads, and it will support up to two sockets. These parts are already sampling and will be ready for a third-quarter launch. AMD didn't, however, make any mention of the mainstream 3000-series Ryzen chips. There is speculation that these will be announced at Computex later this month, but for now it seems that AMD's focus is on the more lucrative server market.

    So, most probably we will see another Ryzen 2 delay, this time till the fall.

    One thing to understand about chiplet design is that it will have real issues with cooling, especially in top end models. As all the heat is concentrated now in one angle in 8 core models with performance of existing 3-4 pipes coolers dropping by 20-25%.

    Watch the cover on Threadripper processors and how they intentionally made it big, as well as check the coolers designs.

  • AMD during its 50th Anniversary luncheon that its 7nm products all carry a 50%, or higher, margin.

    Nice capitalists. Friends of people.

    Despite some Computex announcement real shipping of even 8 core models won't start sooner than mid July, most probably volume will be available only since September.

    Some rumors tell that AMD can try to use higher prices to hold sales volume as they just do not have enough non defective dies. We must also see very strong push towards 4-6 core models, as now most of produced chips can be used in such mode only.

  • DDR4 speed support

    It is from some MB docs.

    Note that it is usually also MB design that limits real DDR4 speed.

    AMD introduced the Ryzen 7 3800X, an 105W 8C/16T processor with a 3.9 GHz base and 4.5 GHz boost.

    Ryzen 7 3700X. This 8C/16T CPU comes with a 4.4 GHz boost and 3.6 GHz base frequency, 36MB of total cache, and a 65W TDP.

    The Ryzen 9 3900X comes with 12 cores 24 threads, a 4.6 GHz boost, 3.8 Ghz base, 70MB of cache, and a 105W TDP.

    Ryzen 7 3700X for $329, the Ryzen 7 3800X for $399, and Ryzen 9 3900X for $499.

    Lack of 16 core CPU!

    Just for reference

    • RYZEN 7 1700X 8-Core (3.4/4) is $189 now in US
    • RYZEN 7 2700 (3.2/4.1) is $209 now in US
    • RYZEN 7 2700X (3.7/4.3) is $284 now in US
    • Threadripper 1950X 16-Core / 32 Threads 3.4 GHz/4Ghz is $499 now in US

    So we can see AMD following Nvidia approach where despite better performance you start paying more for same performance unit.

  • An overclocked 16-core Ryzen based on Zen2 architecture would score 4346 points in Cinebench R15. That’s more than twice than Ryzen 7 2700X and 2.5x more than Ryzen 7 1800X.

    Only multi-threaded performance was shown. The CPU was running at a voltage between 1.428 and 1.572V. This allowed the 16-core AM4 processor to run at 4.1 – 4.25 GHz.

  • Ryzen 3000 is much different from 1st Ryzen in one regard

    12 core model has 6 cores on each chipset working.

    Same can be actually true for most 8 core models that will be 6+2 or 4+4, but rarely 8+0.

    https://adoredtv.com/zen-2-chiplets-why-two-is-better-than-one/

    AdoredTV had been right that all good 8 core chiplets go to Epyc now as profits per one is around 3-5x more compared to consumer product.

    It also tell us that 7nm process is still not mature and has lot and lot of issues.

    With Ryzen two years ago AMD idea had been same, but due to very good production yields they actually intentionally killed second chiplet, so processor came with 8 core fully functional one and another one where 4-6 cores had been good, but it had been disabled.

    Same is true for Threadripper, as almost all of 2 unused chiplets had from 4 up to 8 cores perfectly functional, but to keep prices of higher core count models very high AMD intentionally destroyed them. Yes, like farmers during great recession.

    Intel is doing same, where around 80% of their 2 core models could perfectly had at least 4 cores, but they had been disabled to not ruin prices.

    This is why all people whoa re doing such making enormous damage to society must find their place on the trees.

  • Very complex board for CPU - 12 layers

    image

    Unusual way to connect chiplets to board

    image

    Really risky or may be it is done as they know that such CPUs won't live more than certain amount of time.

  • Ryzen 5 3600 Cinebench results

    image

    image

    If we look at Ryzen 1600 results in comparison it is 27% lower, but on same frequency difference is only 12,5%.

    Ryzen 1600 at 3,9Ghz will make 1386 (most CPUs) and at 4.0Ghz will be 142, almost same as stock 3600.

    It is just one issue, for 12-13% advantage you need to pay 2x more.

  • Interesting.

    Seems like Ryzen 1700 or 1700X are sweet spot for now for poor video editors. They are much cheaper and only 20-25% slower compared to latest 3000 series.

  • Lot of Ryzen 2 tech slides
