Controversy over locking of CPUs to specific vendor platforms[edit]

Covered today by ServeTheHome. This feature, which is likely present in Ryzen CPUs as well opens up the possibility of abuse by hackers to permanently brick the CPU, should they manage to execute code on the PSP. — Preceding unsigned comment added by 81.129.200.169 (talk) 20:06, 9 September 2020 (UTC)[reply]

Zeppelin die?[edit]

What is a Zeppelin die? The term is use but not explained or wikilinked. 49.145.130.102 (talk) 16:34, 17 July 2017 (UTC)[reply]

I believe it's AMD's codename for the specific version of the silicon die used in this first generation of Ryzen, Ryzen Threadripper and Epyc products. I'm not sure though, I'm confused myself. Might be hard to source. —ajf (talk) 16:37, 17 July 2017 (UTC)[reply]
The Zeppelin die, as I understand it, is the 8-core silicon die that is the basis of the Zen microarchitecture. (This includes the memory controller, etc. The whole chip.) ajf is probably right, this may be hard to source clearly. The clearest definitions I have seen is pre-release rumors that otherwise I don't think meet the standard to cite. I don't know if AMD has every officially confirmed the Zeppelin name, though. However, I have seen Zeppelin used in more recent (and citable) sources. It may take some cobbling together of sources to get a proper and well cited definition. Dbsseven (talk) 16:51, 17 July 2017 (UTC)[reply]
Hey, looks like AnandTech's new review of ThreadRipper mentions Zeppelin: http://www.anandtech.com/show/11697/the-amd-ryzen-threadripper-1950x-and-1920x-review/3ajf (talk) 14:47, 10 August 2017 (UTC)[reply]
For now I just made it say "Zeppelin dies (the same die as found in a Ryzen processor)" uncited. —ajf (talk) 14:51, 23 August 2017 (UTC)[reply]

EPYC or Epyc?[edit]

Both are used in the article. Perhaps it should be decided which is correct. 49.145.129.243 (talk) 16:23, 10 August 2017 (UTC)[reply]

Followed convention and made all uses be Epyc, and mention EPYC stylisation in the lede. —ajf (talk) 17:32, 10 August 2017 (UTC)[reply]
Ajfweb, what convention was used? AMD uses EPYC.[1] Within the secondary sources it appears mixed, but the majority appear to also use EPYC.[2][3][4][5] Therefore, I would suggest EPYC is more probably more correct. Dbsseven (talk) 19:59, 10 August 2017 (UTC)[reply]
…honestly, “Epyc” was what Wikipedia was already using more often, so I just went with that. You may be right that EPYC is better. —ajf (talk) 02:54, 11 August 2017 (UTC)[reply]
@Ajfweb and Dbsseven: I would prefer "Epyc" and I think it's also correct according to MOS:TM. -- intgr [talk] 07:46, 11 August 2017 (UTC)[reply]
@Ajfweb and Intgr: Normally I would agree, but it is worth noting the MOS:TM states to use Epyc "as long as this is a style already in widespread use". I am not sure that Epyc is in widespread use (relative to EPYC) and think this exact point is what we should discuss. Dbsseven (talk) 18:34, 11 August 2017 (UTC)[reply]

I guess this is worth revisiting to avoid edit warring with Curly Turkey. Recent edit notes have stated that the stylization of EPYC in the lead is a waste of time. I would disagree. And as I understand the discussion here, at no point was it suggested to remove the stylization entirely. Directly on this topic MOS:TM/STYLE states explicitly it is convention to note the stylized version of a trademark in the lead. Even Curly Turkey's note of MOS:TMCAPS uses as an example eBay, which includes a "stylized" in the lead. Dbsseven (talk) 22:55, 10 October 2017 (UTC)[reply]

"Epyc" is not an acronym for anything, and ALL-CAPS in names and titles is entirely trivial. eBay is an example where the stylization is trademarked and used by third parties. "Epyc" fails both tests. This both is misleading and clutters up the lead. If there's any legitimacy at all to the ALL-CAPS, then the article name itself should be moved. Curly "JFC" Turkey 🍁 ¡gobble! 00:04, 11 October 2017 (UTC)[reply]
The recent edits I am discussing are in the lead and address the stylized version of the trademark. Acronyms are not an issue here. (Acronyms are capitalized throughout the article. Not the case with this edit.) To address your points: EPYC is used in third party sources, as discussed above.[3][4][5] And it is trademarked.[6] Including the stylized keeps with the MOS (MOS:TM/STYLE) and adds clarity to how the product is presented/marketed. (As examples see Dell and nvidia, neither are acronyms.) As for the idea of moving the article, I believe that is directly topical to the discussion above. Dbsseven (talk) 00:40, 11 October 2017 (UTC)[reply]
"EPYC is used in third party sources"—not systematically, and not any more than you would expect third-party sources to randomly ALL-CAPS a trademarked name. The ALL-CAPS in the logo are utterly unremarkable and sticking it up first thing in the lead serves no reader in any way shape or form. It's not even trivia. It's noise. Curly "JFC" Turkey 🍁 ¡gobble! 03:11, 11 October 2017 (UTC)[reply]
MOS:TMRULES states "widespread use", not absolute/perfect use. And EPYC's use cannot be random if it is used consistently by multiple third-party sources. In fact, this cannot be the standard as some articles have multiple "stylized as" versions, i.e. nvidia and Asus.
I appreciate your effort to remove "noise" or "trivia", but these are personal opinions. I disagree and I am not even the editor who added this (Ajfweb). Again, I believe the stylized clarifies the marketing/presentation of the article's subject. Therefore, as this appears to be an editorial disagreement about article structure WP:structure, I propose we follow the policy to achieve a WP:NPOV, which is to follow the MOS. If the issue is that the MOS should exclude this sort of material in general, that talk page would probably be more appropriate for the discussion. Dbsseven (talk) 12:22, 11 October 2017 (UTC)[reply]
perhaps @Intgr: and @Ajfweb: would like to discuss as-well? Dbsseven (talk) 12:25, 11 October 2017 (UTC)[reply]
Dbsseven: "but these are personal opinions"—you've got to be joking. And why are you linking to MOS:TMRULES to support this noise? If MOS:TMRULES applied, we'd need a page move. Worse, have you actually read MOS:TMRULES—particularly what it says about Time, Asus, etc? Curly "JFC" Turkey 🍁 ¡gobble! 10:36, 12 October 2017 (UTC)[reply]
Not joking at all. And I have in-fact read the whole MOS:TMRULES, which states to use standard English in the article. (Which is done in this article.) However, the same page of the MOS also states it is convention to indicate the “stylized as” in the lead, as was done here before the edit. (And the examples in the same MOS:TMRULES referenced often do exactly this: Asus, The Players Championship, Kiss.) So should we follow the MOS, and the whole MOS, or not? Dbsseven (talk) 13:35, 12 October 2017 (UTC)[reply]
And how does cluttering the lead with this noise serve the reader in any way? Can the reader not recognize an ALL-CAPped name without Wikipedia holding their hand? I hope we're not resorting to Wikilawyering to cram everything we can get into the lead. Curly "JFC" Turkey 🍁 ¡gobble! 21:01, 12 October 2017 (UTC)[reply]
I believe it clarifies that the product is not marketed as Epyc, but rather as EPYC. That products will be branded and advertised by the manufacturer in this particular way.[7] (Just as AsusTek Computer Inc. markets is products under the name Asus, nvidia, etc.) I'm not saying this is a huge addition, which is why it only takes 18 characters to include. How is this clutter and noise, exactly? (And I don't believe it is wikilayering to discuss and find common consensus, including using the MOS, so articles are formatted and improve in a consistent manner.) Dbsseven (talk) 18:24, 13 October 2017 (UTC)[reply]

As an additional possibility (in addition to the previous "stylized as", or adding a graphic), the CPU infobox has an optional "brand1" line where we could list "EPYC" to make clear the product branding (the result being "Brand name(s) EPYC"). While away from the MOS for indicating stylization, this would get it out of the lead and make clear it is the branding of the product. I believe this could satisfy most current viewpoints. Thoughts? Dbsseven (talk) 20:13, 13 October 2017 (UTC)[reply]

James: in other words, you prefer to stick to lawyering ("capitalization changes" == ALCAPS is quite the acrobatics). Why not at least go through the motions of providing that "cogent argument for interfering with the reading experience" I asked for? Because you don't actually have one? You simply love yourself them ALLCAPS? Curly "JFC" Turkey 🍁 ¡gobble! 00:06, 22 November 2017 (UTC)[reply]
That would probably be a better discussion on the MOS talk pages. But as I understand it, the reason for a MOS is that no single editor knows "what best serves the reader". This is why consensus building occurs for style, not just content. If a particular case/field is exceptional, then a local consensus can be found. (Curly Turkey, if you'd like the MOS simplified to "Consult Curly Turkey, they know what the reader wants", I wish you the best of luck.) Dbsseven (talk) 23:49, 21 November 2017 (UTC)[reply]
Dbsseven: That's all you got out of this discussion? No wonder we're going around in circles. Curly "JFC" Turkey 🍁 ¡gobble! 00:06, 22 November 2017 (UTC)[reply]
Certainly not all, Curly Turkey. Just summarizing. :) Dbsseven (talk) 00:15, 22 November 2017 (UTC)[reply]
It would be nice if editors could approach articles with the readers in mind, rather than interfere with editors who do. Curly "JFC" Turkey 🍁 ¡gobble! 00:18, 22 November 2017 (UTC)[reply]
I assume all editors do. Dbsseven (talk) 00:22, 22 November 2017 (UTC)[reply]
"they know what the reader wants" is hardly a shining example of AGF, and I don't see arguments being made that ALLCAPS benefits the reader—rather that it can be "gotten away with" if we read the MoS in a particular way. There's no end to the amount of sourcedd information that could be crammed haphazardly into an article that the MoS doesn't (and shouldn't) disallow, and we have mountains of nigh-unreadable messes throughout Wikipedia as a result. Some of us are trying to remedy that.
(If only I had the understanding to do that at Glycated_hemoglobin—I got a medical exam back yesterday and wanted to know what "Haemoglobin A1c" was. Wikipedia was the wrong place to try to find out ... I'm sure it all makes sense to the people who wrote it.) Curly "JFC" Turkey 🍁 ¡gobble! 00:58, 22 November 2017 (UTC)[reply]
How was quoting you ("The reader wants...") within "they know what the reader wants" not AGF? I wished you good luck even. Dbsseven (talk) 01:03, 22 November 2017 (UTC)[reply]
In seriousness, I do know some biochemistry and might be able to answer your A1c question(s) (Olive branch).Dbsseven (talk) 01:08, 22 November 2017 (UTC)[reply]
Thanks! My question is: what is it, and why should I care (apparently my numbers were fine, I just had no idea what the numbers were referring to). Curly "JFC" Turkey 🍁 ¡gobble! 01:50, 22 November 2017 (UTC)[reply]
(Over)Simplified, A1c is checking for diabetes by measuring you average blood sugar over the last few months. This is better in many respects than your current blood sugar. If you just drank a Pepsi and had high blood sugar, that might be okay. But if you were fasting and had high blood sugar, not okay. Measuring A1c takes the timing out of the test. As for what it does: it measures the amount of the hemoglobin (the red, oxygen carrying protein in your blood) which has reacted with the sugar in your blood. This reaction happens naturally, but if you've got more sugar in your blood it happens more often. As your red blood cells have a fixed lifetime, ~3-months, this gives an average of your blood sugar over that time. (Plus in the medical world, I imagine they like things they can measure from blood. It's a lot easier than a biopsy.) Dbsseven (talk) 02:18, 22 November 2017 (UTC)[reply]
Well, that was nice & clear! One more question: they only took one blood sample. How could they know my blood sugar level for the previous three months? Curly "JFC" Turkey 🍁 ¡gobble! 02:43, 22 November 2017 (UTC)[reply]
Because the blood cells only "survive" 3 months. The hemoglobin was modified sometime after it was made, so measuring your A1c from that sample gives an average over that time window. (But this is only an average, they don't know what is was 3 months ago or what it is today, from this test.) A poor analogy: Say you want to know where a tiger generally lives, it's range. You can check on that tiger every day... Or you can note where all the paw-prints are, and conclude it has lived in somewhere within the range defined by those the paw-prints since the last time it rained. (Sorry, not the best analogy but having trouble coming up with something better.) Dbsseven (talk) 03:07, 22 November 2017 (UTC)[reply]
Okay, I think you've answered my question well enough. thanks again! Curly "JFC" Turkey 🍁 ¡gobble! 04:59, 22 November 2017 (UTC)[reply]

Standardizing tables[edit]

All the models tables are in super inconsistent organization. Milan is sorted in descending order of core count, Naples is sorted in ascending order of price, and I'm not quite sure what Rome is doing.

Embedded 7001/7002/9004 series?[edit]

There is no mentions about embedded 7001, 7002 or 9004 series? [1], [2]

Should we treat this as new entries, like Embedded 3000 series is?

Or we just add note to existing 7001/7002/9004 sections (and tables), for example "also available as embedded X model" or something. Specs are more or less the same, what would be the point of identical tables. Rando717 (talk) 21:30, 1 April 2023 (UTC)[reply]

I would add them in a separate section on the Epyc article. Although, if the Epyc Embedded processors are radically different from the normal server ones enough that there would be significance in creating a separate article about them, then creating an article is the logical option. — AP 499D25 (talk) 12:52, 11 May 2023 (UTC)[reply]

Epyc 8004 Siena as part of the standard or embedded section?[edit]

Should the lineup for the Epyc 8004 Siena SKUs be in its current location in the 4th gen table alongside Genoa and Bergamo CPUs or should it be moved under the embedded section alongside Snowy owl? There's already an embedded specific CPU lineup for Genoa, but the parts are basically 1:1 from a spec perspective Justanotherintrovert (talk) 12:03, 18 October 2023 (UTC)[reply]

Epyc 8004 series SKUs are Zen4c based CPUs using SP6 LGA socket, unlike embedded BGA package. I don't think they belong inside embedded section next to Snowy owl series. Zen4 and Zen4c cores are identical (arhitectually), so in my opinion they should remain within 4th-gen section. But I don't think they should be inside same table with Genoa and Bergamo models, because of different sockets (SP5/SP6) and naming convention (8004/9004).

A while ago, I started working on unified design for all Epyc and embedded tables (including Ryzen), but didn't released anything until recently on first gen tables. [example]
I lost time (and will) to search for references about OEM models. If you want, you are welcome to take 8004 section and make "AMD Epyc 8004 series" template from it. Rando717 (talk) 19:01, 18 October 2023 (UTC)[reply]

Epyc 4004 series[edit]

To those who regularly update this article: today AMD introduced the Epyc 4004 series, which are apparently processors that utilise the AM5 platform and go up to 16 cores, with some 3D V-Cache variants available as well: announcement.

I'm guessing they'll go under the "Epyc 4th gen 9004 series" table but tbh I think we should split up the template into separate templates for the Epyc 4004, 8004, 9004 and 9704 processors. — AP 499D25 (talk) 02:13, 22 May 2024 (UTC)[reply]
