  • 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.

  • 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.

    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.

  • DDR4 speed support

    It is from some MB docs.

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

    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.

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

    Nice capitalists. Friends of people.

    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%.

    image

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

  • 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.

  • According to our sources, the same who told us about the death of Global Foundries 20nm, the fully working Zen2 dies are about the 70% of the total production.

    If we think that a fully working Intel XCC die (28 cores) has a rumored yield of 35%, this means that a 64C EPYC2 CPU has got a yield rate of 70% (8 x 8 dies). Almost the double of Intel yield rate!

    If this guys want to compare such they need to compare around 32 nearby cores being all good at the same time and it is 0,7×0,7×0,7×0,7=0,24 . :-)

    In reality having such small good working dies (I assume they include here even 2 and 4 cores working!) is very bad and can explain delays.

  • Interesting development

  • AMD's third-generation Ryzen series CPUs featuring the new Zen 2 architecture, and corresponding X570 chipsets are set to be unveiled at Computex 2019 at the end of May

  • Asus, MSI and Biostar have rolled out BIOS updates for their existing AMD B450, X370, and X470 motherboards to support the upcoming AMD Ryzen 3000-series, codenamed Matisse.

    Some of industry sources tell that we can see biggest marketing hoax in recent history.

    With AMD presenting only 8 core processors with hiked prices and around 20% speed improvement. With 12 and may be 12 core processors that will be left for October-November event.

    Strong rumors are that TSMC is having serious issues with 7nm process costs.

  • Time to start killing the hype a little

  • AMD has confirmed to us that while the new Ryzen processors are compatible with motherboards designed for the first-gen chips, it will require new motherboards to fully support the PCIe 4.0 standard.

    AMD representatives confirmed that 300- and 400-series AM4 motherboards can support PCIe 4.0. AMD will not lock the out feature, instead it will be up to motherboard vendors to validate and qualify the faster standard on its motherboards on a case-by-case basis.

    Motherboard vendors that do support the feature will enable it through BIOS updates, but those updates will come at the discretion of the vendor.

    Most older motherboards could support a PCIe 4.0 x16 connection to the first slot on the motherboard, but the remainder of the slots could revert to PCIe 3.0 signaling rates. That's because any trace routing on the motherboard that exceeds six inches requires newer redrivers and retimers that support PCIe 4.0's faster signaling rates. That means the PCIe slot nearest to the CPU will easily support PCIe 4.0, while the other slots, including M.2 ports, could run at PCIe 3.0. Support could be limited to slots based upon board, switch, and mux layouts.

    One more reason to look for MB with M.2 slot on top of PCIe x16 one.

    Also note that due to PCIe 4.0 new boards will be more expensive.

  • One important note.

    New CPUs will be still dual channel DDR4 memory.

    And still same 24 PCIe total lines (some of the rumors are that they can add extra 4 lines for one more NVMe SSD, but only on X570 chipset).

    X570 can partially save the day if they use 4x PCIe 4.0 for chipset link and start offering 24x PCIe 3.0 lines as output.

    But for existing boards it does not change anything.

    My sources tell that we will see 8 and 12 core CPUs first and 16 core can be delayed or postponed for next gen.

    Real issue is VRM, as if you check AM4 boards Guide you will see that it is not a lot board made with good VRMs, most already have thermal issues with barely overclocked 8 core chips.

    Ryzen 3000 (at least some models) and lot of MB will be presented at Computex 2019.

    July 7 will be official sales start.
