Talk:Pentium D

From Wikipedia, the free encyclopedia

With Hyperthreading, is it seen as 4 processor and, if it's the case, which version of Linux / Windows can support them?

Pentium D doesn't support Hyper-Threading. You need a Pentium Extreme Edition for Dual-Core and Hyper-Threading. --DaveJB 21:29, 11 August 2005 (UTC)

the article claims that Some motherboards based on the 865, 875, 915 and 925 chipsets can work with the Pentium D, but most of them will not work., it be interesting to know which ones or at least include a reference to some discussion.

I agree, and the wording is rather awkward. Any suggestions on how to improve this? RashBold 14:51, 30 August 2005 (UTC)

One point

I hope one day they create just special Pentium that can be used in any kind of pc rather than introduce new things every day so they can take our money.

As good as a dream that may be, it's highly unlikely. If you get into the architecture of a microprocessor, you'd realize that your hopes and dreams won't probably happen. It's a complicated thing, so it's not like they can just create a Pentium-based processor that works on every computer. Remember, there's also licensing and contracts and stuff like that. --CanesOL79 15:25, 7 December 2005 (UTC)

Under the "Presler" heading, the first sentence has a parenthetical comment: "note however that Presler will be a single chip with 2 physical core dies[sic] on it, enhancing yields of the processor". To me, a chip is a die. So the quoted comment contains a contradiction. Is Presler a single chip/die or is it two dice (the proper plural of die), two chips, in one package?

Presler is two dice in one package (LGA 775) Abaca 22:57, 5 January 2006 (UTC)

BUT IS IT ANY BETTER? DOES THE DUAL CORE MAKE IT FASTER IN COMPARISON TO A 2.8 gHZ NON PENTIUM D ? —Preceding unsigned comment added by Diza (talk • contribs) 08:23, 19 May 2006

Yes. Benchmarks can be found at just about any hardware review site. Also, please tone down the caps lock--it makes your message hard to read. jgp 15:17, 19 May 2006 (UTC)
yea, sorry about that. so banchmark-wise do they function as a two core pentiums ? OR(sorry bout the caps) alsmost as good ? I could'nt find any non rant data on the subject...--Procrastinating@talk2me 18:10, 22 May 2006 (UTC)
Well, this page probably isn't the best place to discuss benchmarks, but here are links to some reviews from Anandtech: [1] [2] [3] [4] [5]. I hope they help. jgp 18:26, 22 May 2006 (UTC)
Not really what I was looking for, but Thanks. This article shoudl contains some general benchmarking information, or at least some links (other than those you gave me..) 10:33, 3 August 2006 (UTC)

[edit] Threads?

"Most business applications and games as of 2005 only use a single thread..."

O_o Really? I don't think I've ever seen or written a single-threaded Windows application (business or otherwise), and I'd be surprised if single-thread games have existed at any time in the last 10 years. Are you thinking of processes instead of threads? Or maybe I'm somehow mistaken... can you give a reference? Xezlec 02:23, 31 July 2006 (UTC)

thread, prcocess ? A thread can have many processing sub-threads, bt the main CPU takes them by turn individually.
Okay, whoever wrote that, what are you talking about? I know what a thread is. Is this supposed to be a comment of some sort? Can you elaborate? Xezlec 16:51, 5 August 2006 (UTC)
I think what he is trying to say is that threads and processes are essentially the same thing when it comes to multi-core benefits (CPU takes them by turn individually). Regarding your multi-threaded game statement, I believe most games do the actual work that is the game in one thread. There may be silly little threads handling some menu, window, or even maybe input. The main tasks that make the game like network communication, updating the game state, propagating that to graphics state, drawing a frame, and all those kinds of things are generally done in one pass (and one thread). It all blows up in your face when you try to multi-thread these things, since they depend heavily on each other and must typically be synchronized. Sure it is possible to thread them, but the architecture of the game must be done in such a way where every thread won't be waiting for another thread most of the time. Since the advantage of multi-threaded gaming is essentially non-existent when using one CPU, the added complexity of actually designing a game to take advantage of multi-threading was just not worth it (given that most gaming machines were one CPU). This mentality must now change of course since by the end of this year (2006) most everyone will be using some kind of multi-CPU machine for gaming (including the consoles).
Networking is done in the same thread as graphics? That is surprising. And certainly audio couldn't be, could it? Could you please cite a reference for this? Also, even if other threads are used only for menus and input, that still invalidates the claim as stated. Sorry if I'm being pedantic, but... well, I'm pedantic. Xezlec 03:13, 9 April 2007 (UTC)

[edit] Are they dies or dice?

What's the correct spelling? Currently the article is inconsistent on this matter. —The preceding unsigned comment was added by 195.19.132.65 (talk) 19:12, 14 April 2007 (UTC).

They are dice. "Dies" is not an English noun as far as I know. I'll fix it. Xezlec 22:23, 14 April 2007 (UTC)


"dies" is a noun. you can check it at "http://www.thefreedictionary.com/die". I believe both are plural for "die" but I think "dice" is meant to be used when referring to the cubes with dots on them.

here is the site's definition

die (d) n. pl. dies or dice (ds)

1. pl. dies A device used for cutting out, forming, or stamping material, especially:

  a. An engraved metal piece used for impressing a design onto a softer metal, as in coining money.

  b. One of several component pieces that are fitted into a diestock to cut threads on screws or bolts.

  c. A part on a machine that punches shaped holes in, cuts, or forms sheet metal, cardboard, or other stock.

  d. A metal block containing small conical holes through which plastic, metal, or other ductile material is extruded or drawn.

2. pl. dies Architecture The dado of a pedestal, especially when cube-shaped.

3. pl. dice

  a. A small cube marked on each side with from one to six dots, usually used in pairs in gambling and in various other games.

  b. dice (used with a sing. verb) A game of chance using dice.

[edit] Physical or emulated cores?

This is a weird question, but i wanna know. Is it true that the Pentium D processors doesn´t have 2 real cores, that they actually emulate the dual-core architecture? And this bring another question: Which processor has a better performance? Intel Pentium D945 dual at 3.4Ghz or the Core 2 duo E6400 at 2.1Ghz?? I know this isn´t the place to post this but, i really need to know, pleaseBig butt gangsta 01:44, 14 May 2007 (UTC)

All Pentium D processors have 2 actual cores. Any forum about computers could answer the rest. — Aluvus t/c 02:14, 14 May 2007 (UTC)
The Pentium 4 HT is the one that has two virtual cores, but only one real one. The Pentium D, as stated above, has two physical cores. And as for performance, the Core 2 Duo's microarchitecture is widely accepted as being superior to the Pentium D's. Less heat, and more performance, even at lower clock speeds. Look at the articles for NetBurst and Intel Core microarchitecture for more details. Suigi 03:56, 29 June 2007 (UTC)

[edit] BroadWater Chipset

I thought Broadwater is Intel 965 not 975. My motherboard is MSI 965 Neo F and is cleary states Broadwater at the bootscreen. The text seems to be incorrect to me... See here: http://www.channelregister.co.uk/2005/11/14/intel_broadwater_schedule/

[edit] Multi Chip Module

The least biased of the 3 names listed in the multi-core article is the multi-chip module, and I do advocate explaining the difference, but it is already mention in the implementation and I don't wish to inhibit your efforts, we need terms are correct, and not degratory, double-core would imply that Pentium D is NOT a dual core which it is.

[edit] Xeon ambiguity

The phrase "it will face the same bus contention issues as a pair of Xeons" seems dubious or at least ambiguous, since there are both single and dual core Xeons, according to that article. -- Beland 02:25, 17 July 2007 (UTC)

Adding "single-core" would resolve any such issues, no? In any case, dual-core (or n-core) Xeons would still face the same issue, just to a different degree. — Aluvus t/c 03:28, 17 July 2007 (UTC)

[edit] Dies vs. dice, redux

I've changed the text to use "dies" instead of "dice" as the plural of "die". Even if the former weren't more commonly used for the IC component anyway, "dice" has too much of a connotation of "gaming cubes" for a general encyclopedia, which is what Wikipedia is. Besides, Merriam-Webster Online explicitly states that "dice" is the plural of the cube and that "dies" is the plural of the manufacturing term from which the IC fabrication term is derived. ~ Jeff Q (talk) 21:11, 7 September 2007 (UTC)

[edit] Wrong Successor

Hey, i'm not 100% sure, but I don't think that the successor to the Pentium D is the Core 2 Duo. It is most likely the Dual Core "1"... http://en.wikipedia.org/wiki/Intel_Core_%28CPU%29 This is probably an error since many people confuse the Dual Core with the Core 2 Duo. Perhaps someone could confirm and then change the successor part of the article... ? purpleidea (talk) 17:55, 11 February 2008 (UTC)

Pentium D was principally a desktop CPU. Core Duo was only a laptop CPU. Core 2 Duo is both a desktop and laptop CPU, and for all intents and purposes it is the successor to both. All of these are examples of dual core processors. — Aluvus t/c 00:46, 12 February 2008 (UTC)

[edit] MiB and KiB v.s. MB and KB

Note. For interested authors, debate and a vote is ongoing on Talk:MOSNUM regarding a proposal that would deprecate the use of computer terms like “kibibyte” (symbol “KiB”), “mebibyte” (symbol “MiB”), and kibibit (symbol “Kib”). It would no longer be permissible to use terminology like a “a SODIMM card with a capacity of two gibibytes (2 GiB) first became available…” and instead, the terminology currently used by manufacturers of computer equipment and general-circulation computer magazines (“two gigabytes, or 2 GB”) would be used. Voting on the proposal is ongoing here. Greg L (my talk) 21:16, 27 March 2008 (UTC)
