    I'm not an insider, so cannot guarantee anything. But, the limited 10nm low power dual core mobiles, then the replacement a year later, but no H or G actually does make sense. Also, Cascade and Cooper lake for HEDT and Server have long been known to be 14nm. Seems they are finally porting the Ice Lake/Sunny Cove back to 14nm.

    With that said, and what @tilleroftheearth isn't saying, is 14nm is near its limits. The microarch will get better, meaning Comet Lake and beyond will have increases in single threaded performance due to improved IPC from architecture improvements. All that means is that Intel won't get the process improvements. So it does NOT mean Intel will not have more to get out of the tank, just means that the hopes of lower power is lost.

    In fact, prior roadmaps showing Intel's release for the 9900K were only off by within two quarters on the products, depending which roadmap you looked at (the first released one turned out more accurate on that, whereas the second, later released one must have been an earlier version because it had the 9900K coming in Q1 of 2019, rather than late Q3 to Q4, like the first one).

    If this one is anywhere near as accurate as those previously published, Intel has a process node problem.

    Ryzen 7 2700X and Radeon VII Gold Editions Tomshardware.com | April 29, 2019

    Despite the numerous leaks and rumors, the Ryzen 7 2700X 50th Anniversary Edition will not differ from the standard version in terms of clock speeds. There were high hopes that AMD would delight us with a cherry-picked chip with higher clocks, much like what Intel did with its Core i7-8086K processor.

    Nonetheless, the Ryzen 7 2700X 50th Anniversary Edition will surely find its way into hardcore AMD aficionados' collections.

    The Ryzen 7 2700X Gold Edition also includes a sticker with AMD CEO Lisa Su's autograph and a coupon for a free AMD 50th anniversary t-shirt. The processor is available today at numerous retailers.

    AMD 7nm ZEN 2 64 Core & 32 Core CPU Specs & Benchmarks Leaked Wccftech.com | May 19, 2019

    In fact it runs at a base frequency of 1.7 GHz and a turbo frequency of 2.4 GHz. Which is surprising considering it has half the number of cores. Although this particular chip could be a low power part, which would explain the low clock speeds. And unlike the 64 core ES, this part only appeared on the database once so far. Add to that fact that this entry is for a Dell PowerEdge R6515 server, this means that we’re bound to see more of AMD’s EPYC Rome parts as they’re sampled to the company’s partners.

    An ES is by no means a final product.
    So, its possible the clocks aren't final... or if they are, we don't know how this will affect performance (depending on IPC increases).

    In my searching, I didn't see any leaks or rumors that said the performance of any of the AMD 50th Gold Anniversary CPU / GPU / Motherboards were anything other than a celebration of the event editions, and none advertised more performance or additional functional features.

    No one advertised anything extra besides a Lisa Su "signed" element and / or T-shirt to go with the "different" accented (colored) features and box of the product.

    There was also an AMD game pack change around the same time - change in selection of pack-in games - but it wasn't advertised as a Gold Edition special.

    There were a couple of opportunistic reviewers that tried to make like there was going to be a difference to get clicks, but otherwise no one suggested or advertised or leaked that any performance boosts were included with the 50th anniversary components.

    Agreed.
    When the Gold Anniversary CPU's and gPU's from AMD were announced, I also hadn't come across any claims for clock increases or performance changes.
    The only thing that was advertised was Lisa Su signature, and that's it.

    Good thing we have one week until the keynote and should receive final clock speed around then.

    "Michael at Phoronix will be posting a new article later today on high core-count Xeons. These presumably cap out at 28 cores/56 threads, as the Cascade Lake-AP CPUs only go into dedicated Intel built systems which he is unlikely to have access to. Cascade Lake-AP isn't a real product offering to begin with; it's a panicked, smoking hot, water-cooled PR stunt to make Rome look less game-changing.

    But yes, at the exact moment that AMD is about to release its truly game-changing Rome monster, Intel is actually delivering significant regression in performance, thanks to their decades of cutting corners in security. The schadenfreude is delectable! And next year, the game changes again, and in a big way, with Milan..."

    A Look At The MDS Cost On Xeon, EPYC & Xeon Total Impact Of Affected CPU Vulnerabilities
    Written by Michael Larabel in Software on 20 May 2019.
    http://forum.notebookreview.com/thr...atches-and-more.812424/page-126#post-10913136

    "...If looking at the geometric mean of all the benchmarks carried out, the EPYC 7601 averages out to about a 1% hit with its Spectre mitigations.

    The dual Xeon Platinum 8280 Cascadelake setup with its mostly hardware-based mitigations was slower by 4% with the relevant mitigations enabled.

    (l1tf: Not affected + mds: Not affected + meltdown: Not affected + spec_store_bypass: Mitigation of SSB disabled via prctl and seccomp + spectre_v1: Mitigation of __user pointer sanitization + spectre_v2: Mitigation of Enhanced IBRS IBPB: conditional RSB filling).

    Meanwhile the dual Xeon Gold 6138 server that unfortunately doesn't have the hardware mitigations saw a 11% hit from the benchmarks run with these Spectre / Meltdown / L1TF / MDS mitigations or 15% if disabling Hyper Threading as an additional measure based on the benchmarks carried out today."

    Looks like 4287 was the score. My 1950X@4.2GHz gets 3652. That is a 17% increase, and there is a chance the 4.2GHz may or may not have been all core on that chip. For a comparison, the 7960X does not hit that score until 4.7GHz or 4.8GHz. This means when that 16-core part is released, it very well could eat the HEDT market's lunch!

    Now, just want to know what lays ahead for Threadripper!

    Also, that explains that the Epyc Rome chips upcoming will be able to hit around the same frequencies of the first gen Epyc chips.

    6-days (actually, I'll be watching the presentation Sunday night due to where I live). Times they are a changing!
