Talk:MMX (instruction set)

Etymology
Um, I have always heard that it originally stood for MultiMedia eXtensions, although it doesn't officially stand for anything since MMX is an Intel trademark. But I have *never* heard it called Matrix Math eXtensions.

 * Ditto. According to : MMX, which was rumored to be an acronym for "multimedia extensions," does not officially stand for anything. It certainly is, however, a multimedia-enhancing technology. Anárion 14:02, 14 Jul 2004 (UTC)


 * For what it's worth, MMX can also be read as 2010, thus a Roman number. That could actually some engineer's joke or the last digits of the product number and other explanations of MMX might simply be backronyms. Keep in mind that Pentium derives simply from the Greek word for 5. --82.141.49.35 14:21, 3 January 2006 (UTC)


 * I once heard (honest!) that MMX stands for Marketing Maneuver X. The final X would stand for nothing and would have been added just because laypeople tend to perceive acronyms ending with X (like PSX, 3DFX, WinMX, GeForce MX) as 20% more innovative.

 * 27% more innovative! :shakesfist: -Obeejw 20:08, 24 September 2006 (UTC)
 * 23% according to recent research. --Soyweiser 11:37, 10 April 2007 (UTC)


 * What about MultiMedia Xperience: "MMXTM SEE IT! HEAR IT! EXPERIENCE IT!" (logo)?--89.41.55.207 13:12, 24 August 2007 (UTC)

Can you trademark a year? MMX is 2010 (next year, as I type this) in Roman Numerals. —Preceding unsigned comment added by 86.130.42.237 (talk) 04:58, 12 June 2009 (UTC)

MMX on original Pentium
I remember back when we had a vanilla P1, my dad picked up a floppy containing software that promised MMX performance on a regular P1. I doubt it ever did, but that'd be an interesting thing to have in the article, no? I'll see if he remembers anything. 59.101.42.137 15:21, 20 May 2007 (UTC)

KNI / MMX2 / MMX EXT
There's no mention in the article of MMX2 / MMX EXT / KNI (Katmai New Instructions). Can someone add that? —mjb 23:27, 27 July 2007 (UTC)
 * SSE is mentioned toward the bottom of the article already. — Aluvus   t / c  23:41, 27 July 2007 (UTC)

No explaination
The technical details section just talks about the advantages and disadvantages of MMX with a little on how it interacts. It's hardly informative on the way in which the extensions work. —Preceding unsigned comment added by 86.129.82.95 (talk) 00:39, 28 June 2009 (UTC)

Exactly. What does MMX do? --Ametheus (talk) 14:52, 12 September 2009 (UTC)


 * The technical details do actually tell you how MMX works: using 64-bit registers, you can perform operations—like add/subtract—on 2, 4 or 8 numbers simultaneously. It's just that it's implied you know what sort of operations are usually available to processors, and what it means to have 64-bit registers on a 32-bit CPU. The section is also interlaced with factoids about aliasing the FPU— - stuff that is not necessary to knowing how MMX actually works, it's only an implementation detail. The whole section could be rewritten to be clearer to laymen, with diagrams on packed operations etc. C xong (talk) 01:19, 22 March 2010 (UTC)


 * There is a fair bit of information about how MMX works, but very little information about what MMX does, i.e. what benefits the end user gained from getting a CPU with MMX. The implication from the hypothetical name "MultiMedia eXtension" that it has something to do with multimedia doesn't really suffice. Basswaster (talk) 07:34, 29 March 2017 (UTC)

Instruction listing
Why 3DNow! article has a listing of instructions but not MMX article? ``2A01:119F:220:9400:CC99:A0FF:9928:2C74 (talk) 11:23, 26 November 2023 (UTC)
