Talk:POWER6

Revamp

I did some heavy editing and added a lot of references. I think it's needed at this point when tere are very little publicly available documents from IBM. -- Henriok

Many news sources are using Power6 as the capitalization.

Fixed! Good call! -- Henriok 20:50, 21 May 2007 (UTC)

Errors

This quote : "Dr Frank Soltis, an IBM chief scientist said IBM had solved power leakage problems associated with high frequency by using a combination of 90nm and 65nm parts in the POWER6 design"

not only needs a citation, but it is factually wrong. It should be removed

I'm sure it is, but not according to the article: IT Week, 08 Feb 2006. -- Henriok 12:28, 21 June 2007 (UTC)

That is one article, from over a year ago, if you wish to keep it it'd be nice to have some proof that is more recent and authoritative.

I'll point out that Dr. Brad McCredie is the Chief Engineer on Power6, not Dr. Soltis.

The IT Week article also states that it has a 2 stage pipeline; Ars Technica gives a more plausible 15.

MCM Facts

I don't think that the POWER6 is packaged on a MCM with eight dies like the POWER5, as the article states. My factsheet from IBM has no mention of this. Also, if one looked at the IBM press kit, the chips in one of the pictures shows one die per a chip. Can anyone confirm wether it is packaged in a MCM or not? -- Rilak 18:42, 18 August 2007 (UTC)

The POWER5 comes in three different kinds of MCMs: dual-, quad- and octa-chip (one cache chip per CPU chip). The POWER6 comes in mono-chip packaging for now but IBM is planning for four-chip MCMs (eight cores) accordning to the Real World Tech article. Every configuration are not available from day one. For now it's just a singe chip module, but there seems to be at least four-CPU modules planned. The pictures of the packaging only reveals one chip. I don't know if the external L3 chip is located on another module or hidden inside the packaging. -- Henriok 12:28, 19 August 2007 (UTC)

Word length?

Just out of curiousity, what is the basic word length of this thing? Cardamon (talk) 10:23, 27 November 2009 (UTC)

POWER6 uses 64-bit registers but the Power ISA defines word length as 32 bits. -- Henriok (talk) 13:30, 27 November 2009 (UTC)

The article states that it can do "two independent 32-bit reads or one 64-bit write per cycle". But the source (Information week) says nothing about the number of bits. I seriously doubt that the Power6 needs both read-ports of its D-Cache to fill a 64 bit register via two 32 bit loads.--85.216.120.20 (talk) 13:01, 31 December 2009 (UTC)

External links

Further information: Wikipedia: External links

Some things just grow during incremental edits and sometimes get out of hand. The "External links" section, one of the optional appendices, was expanded to 6 entries. Three seems to be an acceptable number, and of course, everyone has their favorite to try to add for a fourth. Consensus needs to determine this.

• A tag indicates concerns.

However, none is needed for article promotion.

Some links may be included in WP:ELNO, or What Wikipedia is not (policy) such as WP:NOTREPOSITORY or WP:NOTGUIDE.

• WP:ELDEAD may apply.
• ELCITE applies : Do not use {{cite web}} or other citation templates in the External links section. Citation templates are permitted in the Further reading section. Others, listed below:
• ELpoints #3) states: Links in the "External links" section should be kept to a minimum. A lack of external links or a small number of external links is not a reason to add external links.
• LINKFARM states: There is nothing wrong with adding one or more useful content-relevant links to the external links section of an article; however, excessive lists can dwarf articles and detract from the purpose of Wikipedia. On articles about topics with many fansites, for example, including a link to one major fansite may be appropriate.
• ELMIN: Minimize the number of links.

The External links guideline This page in a nutshell: External links in an article can be helpful to the reader, but they should be kept minimal, meritable, and directly relevant to the article. With rare exceptions, external links should not be used in the body of an article.

Second paragraph, acceptable external links include those that contain further research that is accurate and on-topic, information that could not be added to the article for reasons such as copyright or amount of detail, or other meaningful, relevant content that is not suitable for inclusion in an article for reasons unrelated to its accuracy.

• • Please also note:
• WP:ELBURDEN: Disputed links should be excluded by default unless and until there is a consensus to include them. Please do not add back more links without consensus. Simple solution to facilitate career maintenance tag. Move links here for discussion.
