Talk:Pentium D

Note, there should be some mention in the little Intel Processor categorization below that the Core Duo comes in a 32-bit variety and all Pentium D's are 64-bit (although they can run as 32-bit processors). It's not very good to compare Core Duo's to Pentium D's. I had a Toshiba A135-S2276 with a Core Duo 1.6 Ghz processor, and it seems slower in performance than my Pentium 4 2Ghz IBM Thinkpad T30. And my Pentium D 2.8Ghz Dell Dimension 9150 outperforms the Toshiba by quite a lot even though there is only a Ghz difference in processor speed. All of these I'm running in 32-bit mode although I've tried the Pentium D in 64-bit Xubuntu and seemed to work okay. 97.123.21.120 (talk) 22:53, 1 July 2009 (UTC)

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? DHR 20:16, 5 January 2006 (UTC)

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

Unclear

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)

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)

I think this article should be updated now. All games coming out now use dual core. But how does the Pentium D do? I know the Pentium D is not built for todays gaming, but in theory it should be twice as powerful as a single core pentium 4, when you are playing todays games. The article just says "only uses one core for games, so no point in having a Pentium D", or words to that effect. But, even just a few years after that's been written, it reads like a very outdated comment indeed. 80.47.86.164 (talk) 18:45, 22 January 2010 (UTC)

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.

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)

For some reason, I have a Pentium D running at a stock 2.8GHz, and yet I believe that it only has a single core... It does not have the processing power of a dual core! —Preceding unsigned comment added by 96.232.6.49 (talk) 17:09, 7 December 2008 (UTC)

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/

http://www.neoseeker.com/news/story/5155/

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.

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)

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)

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)

thats not right the main succesor was the pentium dual core after, 2 week intel launch the core 2 duo series but at the first was a laptop-only proccesor. the main successor the pentium dual core--66.128.43.125 (talk) 17:45, 12 September 2008 (UTC)

The Pentium Dual Core is only a laptop part, and only a "budget" part at that. The Pentium D was a desktop-only, mid-range-ish part. They are targeted at completely different markets. — Aluvus t/c 23:10, 12 September 2008 (UTC)

The pentium dual core is indeed a budget part but it doesn't appear to be laptop only. Dell seem to be putting it in many of thier cheaper desktops. Plugwash (talk) 22:55, 26 January 2009 (UTC)

4 months ago, and certainly nearly a year ago when this topic was started, it was very much a laptop-only part. Intel has quietly brought it to cheap desktops, perhaps as a reaction to the worsening economy. — Aluvus t/c 03:03, 27 January 2009 (UTC)

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)

The Pentium D represents a major historical milestone in processors

This is the first processor I know of that can run any Operating System 32 bit or 64 bit. With slight revision, for example, a Dell Optiplex GX-620, (if one researches this/Pentium D), there is recorded people who have been able to run operating systems, both Windows 8.1 32 Bit, 64 Bit, and Windows 10 32 Bit, 64 Bit. One person above was able to run Ubuntu 64 Bit on this processor. I know it easily runs the most modern version of Lubuntu 32 Bit.

This chip from 2005, to present 2018, is able to run modern operating systems. Never before in the history of computing has a processing chip been able to run operating systems for 13 years! Easeltine (talk) 16:48, 26 January 2018 (UTC)

I'm sorry to burst your bubble but the Pentium D isn't a milestone, in my opinion, mainly steaming from the fact that AMD's Athlon 64 came out around the same time and supports Windows 10 while not being a space heater. Benchmarks of the Athlon 64 X2 3800+ from 2005 showed that it performed better than the Pentium D 830. The Pentium D is really just two Pentium 4s bonded together.

References

Too much negativity

The whole article conveys a very negative image of the Pentium D. I do not think this is justified. It was a milestone in the CPU history of Intel (C)/TM. It was the first dual core mainstream CPU from the company and its performance was not at all bad, see websites with CPU benchmarks which show the Pentium D 960 @ 3.60 GHz is more than twice as fast as the Pentium 4 670 @ 3.80 GHz ... Which again is no surprise, since the Pentium D is basically 2 x Pentium 4 glued together. Regarding the heat aka TDP, it was not as bad as portrayed in the article, either: 130 W TDP for more than two times the processing power of the Pentium 4 670 @ 3.8 GHz, which was rated at 115 W TDP -- come on, guys, you have to admit that was not bad at all. And there were power saver editions too like the Pentium D 945 @ 3.40 GHz with only 95W TDP, which was really a good value for a dual core CPU, which was faster (faster as in higher benchmark values, not as in higher GHz clock speed) than many of the later entry level Core 2 Duos and their respective Celeron and Pentium Dual Core variants. So I really think the whole article needs to be rewritten to reflect the positive values of the Pentium D in an objective light. -- Alexey Topol (talk) 08:40, 28 June 2022 (UTC)

While yes, in a vacuum, the Pentium D doesn't seem too bad but AMD exists and they have beaten Intel to 64 Bit and dual core (Athlon 64 and Athlon 64 X2 respectively). These processors ran cooler and were faster than Intel's offering. The NetBurst architecture that the Pentium 4 and D use is honestly a horrible architecture to the point that even Intel abandoned it in favour of all new chip designs be based on the mobile Pentium M chips which were based on the Pentium 3.
