"One issue that is not immediately obvious until you start using a dual core or processor system is that Cool'n'Quiet is somewhat incompatible with performance. Cool'n'Quiet works by checking how active the processor is while running and adjusting the speed and voltage up or down appropriately. If the processor is idle it slows it down, and if it is busy it speeds it up. With X2 cores this is actually detrimental to performance as both cores are not treated independently by Cool'n'Quiet but rather as a single unit. In the typical case where one core is busy and the other is idle you end up with a bizarre ping pong effect as the cores are continuously sped up and slowed down, resulting in an overall performance loss rather than the expected gain. To reap optimum performance one has to turn Cool'n'Quiet off and forgo the benefits in power saving and heat reduction."
I have CoolnQuiet enabled and constantly monitor my processor speed and voltage both in windows and linux. I have yet to experience this "ping-pong"-effect.
Hmm. The picture says that it is of a 3800+ Athlon X2 E6. However, the text says that all Manchester cores are E4. If all 3800+'s are E4, then how is this picture possible? -- Roguelazer 03:35, 29 December 2005 (UTC)
This is a bit confusing. I guess what's it's trying to say is that 3D games can't be effectively multithreaded without disproportionate development time so most games are not multithreaded. The Quake III engine is multithreaded however it's not really done that well/effectively multithread (or perhaps it's not possible to do it well) so it doesn't provide that much of a benefit. I.E. Some time was spent making the engine multithreaded but not as much as is necessary for it to work very well (but more time then most other games.
At the moment, it sounds like it's saying the Quake III engine was effectively multithreaded without a disproportionate development time Nil Einne 01:15, 2 June 2006 (UTC)
While this is probably true, could some provide a reference? Also, perhaps this needs to be clarified. Is it really always going to require a lot of development time or could it be partially just that game programmers have never had a need to make multi-threaded game so they haven't and so learning how to do it is going to take a long time but once they start to get the hang of it, it'll be a lot simpler?

Many users I've seen have commented on the improved responsiveness of a computer in normal, everday multitasking use. This isn't really mentioned/clear since it only suggests intensive multitasking scenarios and only performance (not responsiveness) which perhaps makes it seem like your decompressing an archive, while compressing a video and playing a game all at normal priority (or maybe having 50 FireFox tabs/windows along with Photoshop, Acrobat, Illustrator open)... Of course, this may be related to Windows scheduling code but it needs to be mentioned. Nil Einne 01:07, 2 June 2006 (UTC)
the energy efficient X2s.. eg 3800+ @ 35W..?
I was under the impression that the 35W X2's had different model numbers. This should be added in another paragraph - the model numbers and technologies should be researched and sourced. Also, isn't the 35W feature part of Cool'N'Quiet (which also seems to be absent from the article since the edit mentioned at the top of this talk page)? Fiskars007 00:12, 27 July 2006 (UTC)
Removing this paragraph, as it's not specific to the Athlon 64 X2, it's about multi-core processors in general: Stevage 04:29, 27 October 2006 (UTC)
At newegg, many of the product reviews state that the Intel version is superior. I checked, but they are also $100 more. Is the Intel equivalent of the same price actually superior? -- Can Not 15:49, 12 February 2007 (UTC)
I believe that AMD attributes their Athlon X2 processors with something called "ordering p/n" which points out the chipore 2 Duos. Also, what does the DC in the recently announced 64 X2 DC 6000+ chip mean? 66.36.131.228 10:30, 20 February 2007 (UTC)
I believe that AMD attributes their Athlon X2 processors with something called "ordering p/n" which points out the chip's characteristics (core type, power consumption, stepping, etc...) Unfortunately I can't find a single reference to that naming scheme. Can anyone point it out and add a section to the article? -- Mecanismo | Talk 09:58, 25 April 2007 (UTC)

There's nothing on the article about the RDTSC timer/counter issue. Anyone willing to point that out somewhere and maybe that there's a solution in form of a resident program provided by AMD ( the dual-core optimizer) that occasionally syncs the counters, and a hackish solution from Microsoft (they just instruct you to limit the application to single core). -- M.A. 13:33, 25 July 2007 (UTC)
This makes no sense since AMD's laptop processor at the moment is the Turion, but there is a 15.4" screen Compaq Presario notebook, model F572US, that says it has an Athlon 64 X2 TK-53 processor. That sounds like a Turion, but it bears an Athlon 64 X2 sticker on the laptop itself and its specs (see link) say it has a "1.7 GHz AMD Athlon ™ 64 X2 Dual-Core Mobile Technology TK-53"? Is this something like the Intel Pentium Dual Core (a rebranded product, IOW)? 205.157.110.11 21:29, 27 August 2007 (UTC)
