Cluttermagnet Posted June 20, 2014 Share Posted June 20, 2014 Given a P4 2.8GHz/1M/800 and a P4 3.2GHz/512K/800, which should be faster on any one given mobo which can run either? I'm guessing maybe the slower CPU with the double size L2 cache? Inquiring minds want to know... Clutter Quote Link to comment Share on other sites More sharing options...
abarbarian Posted June 20, 2014 Share Posted June 20, 2014 http://ark.intel.com/compare/27501,27496 I would have said the 3.2 but it is a tricky question. Try em both out. Quote Link to comment Share on other sites More sharing options...

I'm guessing maybe the slower CPU with the double size L2 cache? Inquiring minds want to know... Clutter How much cache is enough depends upon what's running. In general, the higher clock rate will be of greater value unless you are doing a lot of process swapping. (And just how much is "a lot"?) Seeing that Intel replaced the 2.8 chip with the 3.2 in their product line up, they must have felt it was an improvement. Quote Link to comment Share on other sites More sharing options...
V.T. Eric Layton Posted June 20, 2014 Share Posted June 20, 2014 I've never been a big Intel fan, but I do know that the Prescott (P4 3.2GHz/512K/800) core was a much better processor die than the Northwood. Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted June 21, 2014 Share Posted June 21, 2014 Yes, you can't just go by speed or cache. The specific processor die makes a lot of difference too. As well as the speed of the hard drive (5400 or 7200) Quote Link to comment Share on other sites More sharing options...
Cluttermagnet Posted June 22, 2014 Author Share Posted June 22, 2014 Well, I recently found a number of good P4 chips on the internet reasonably priced and guaranteed. All pulls, of course. 8USD will get you one of those 2.8GHz/1M/800, and that includes shipping. They are so obsolete. Anyway I bought one of the 2.8GHz Prescott CPU's to try in a box that has 2.4GHz/512K/800. That's my gut feeling too, guys- the Prescott was supposed to be a worthwhile improvement over the Northwood. The lesser CPU will in turn upgrade a lesser tower where it will push that mobo to its respective limits. And so on. I always avoided those 5400 hard drives, Fran- knowing that was such a bottleneck. I think every single one I have is 7200. I think it is a tricky question. It's not like these are poles apart. But there may be some difference. FWIW the 3.2 GHz will just stay where it lives now. A slightly faster Northwood vs. a slower Prescott. Who knows? But OTOH the 2.4 to 2.8GHz upgrade is definitely going to be worth it, and the mobo will support the larger cache, so why not?

I would have mailed one to you for nothing. Still can, if you'd like. I'll go out there and see what I have. Let me know... 2 Quote Link to comment Share on other sites More sharing options...

Cluttermagnet Posted June 29, 2014 Author Share Posted June 29, 2014 Eric- That's a very kind offer. If you have some 'medium fast' to 'fast' P4's, I should take you up on that. I'm slowly compiling a list of my mobos and their limitations so far as RAM and CPU architecture. I did buy a couple out on the net. They are sooooo cheap now. I'll post again to this thread in maybe the next week or so, after I've gathered all the info. David, I didn't understand that you actually needed one of these P4s.

Cluttermagnet Posted June 29, 2014 Author Share Posted June 29, 2014 Aryeh- Yes, I'll get back to you 'shortly' in this thread. I have the 2.8GHz IC 'loose' as I just bought it on the internet. So there I can provide an exact model number like "SM5BH" or whatever (I'm totally making up that example number off the top of my head). It is a Prescott type, I believe, and is 2.8GHz/1M/800. I'll post later from my other location where the IC is. BTW I also recently bought a 3.0GHz/1M/800 off the net. Not yet received but might be in Monday's mail. USD 5.95 including shipping! Wow- these things used to go for nearly 300.00 when new! The 3.2 GHz is socketed in a working tower so I may not be able to extract the exact model number through the 'hardinfo' utility in Linux. But for sure I can say it is in the Northwood family and is a 3.2GHz/512K/800FSB. The software utility probably will give broad clues such as 'stepping number', etc. This can probably be figured out on the internet using the various sites such as 'CPU upgrade'. They list all the data. Hello, Do you know the exact models of the CPUs in question? Regards, Aryeh Goretsky Quote Link to comment Share on other sites More sharing options...

Cluttermagnet Posted July 9, 2014 Author Share Posted July 9, 2014 Regarding my Northwood CPU 3.2GHz/512/800, I get this from the Linux utility hardinfo: Family, model, stepping = 15, 2, 9 Meanwhile, I have put to work both the 3.0GHz/1M/800 and the 2.8/1M/800 bought on Ebay at very reasonable prices. Both are pretty fast in terms of page refresh within Firefox and such. Also look pretty good on the Blowfish test available in hardinfo. Hmmm- it's pretty sluggish running Blowfish on the 3.2GHz right now. I have 2G of DDR 400MHz. Firefox is very laggy on this box, don't know why. Anyway, I get 28.97 which is slightly worse than a hypothetical Celeron M 1.5 GHz at 26.19s. I'm saving this as mainly a note to myself, but as I remember the two Prescott CPU's at my other location are running this test in something like 10-12 seconds. Maybe I'll shut down FF and run it again. I have a lot of memory being hogged by my browser. Quote Link to comment Share on other sites More sharing options...
Cluttermagnet Posted July 9, 2014 Author Share Posted July 9, 2014 (edited) OK, I rebooted the 3.2GHz Northwood and got 10.78s, much more reasonable. FF is such a resource hog. Nothing like the fresh, minty taste of a rebooted computer... I think I'm getting closer to an answer. Seems I remember one of the Prescott CPU's doing something like 9+ seconds with Blowfish- so only marginally faster if so. Oh, and the other Prescott, probably the 2.8GHz, maybe 12+ seconds? Going by memory here... Edited July 9, 2014 by Cluttermagnet Quote Link to comment Share on other sites More sharing options...
Cluttermagnet Posted July 9, 2014 Author Share Posted July 9, 2014 (edited) On my MSI MS-7037 with 2.8GHz/1M/800 I just got 10.77s doing Blowfish- and that's with only 1G DDR 400 RAM. I later tested again using Blowfish and 2G DDR 400. This time I got 12.35 seconds. Go figure... Still happy with it, though.

Cluttermagnet Posted July 15, 2014 Author Share Posted July 15, 2014 Eric- I really like that Summer Break kitty. So the processor did come on Monday as they promised. I finally opened it some time early Tuesday morning. Looks like this one is the next model up from what I run, unfortunately. I think you mentioned a part number in some other thread than this one. You said something like 2.8GHz/1m/800/nnn, I forget what exactly the nnn number was, but that should have tipped me off. So what it is is a 775 'pin' CPU of the type 775-land FC-LGA4. And it has 'lands' instead of pins like the 478's have. The tipoff is in the model number, a five digit code. This one is marked SL8PP. I should have asked you for the part number. The types I can use are generally in the 7- series, like SL7PM for example, that's a P4- 478 with 1M L2 cache, 800FSB, 3GHz. The ones in 478- pin have part numbers with no /nnn number at the end. If it's OK with you I'll just hang onto it, even though I can't use it right away. Time will come when I will be very glad I have a spare one. Sooner or later someone is going to give me a P4- 775 mobo, and then the fun starts. I would also need to get some DDR2 for such a board. They keep getting faster as the pin count goes up, and some of them with the higher pin numbers would be the earlier dual and quad processors. Anyway, thanks so much for sending it Eric. If you want it back I'll send it, or if later you or someone else wants, I'd send it. But otherwise I'll keep it. It's just a question of time, eventually I will need it.

b2cm Posted July 23, 2014 Share Posted July 23, 2014 If this was me, I'd decide based on this order (1) which had the Hyperthreading feature, (2) larger L2 cache, and than (3) higher clock speed. You also need to check out motherboard compatibility and heatsink requirement when considering Prescotts. 1 Quote Link to comment Share on other sites More sharing options...
Cluttermagnet Posted July 23, 2014 Author Share Posted July 23, 2014 (edited) Hi, b2cm- Have not seen you for a while. Nice to have you back! Your comments should be very useful as I puzzle my way through all this. Well, Clutter has bought about four old P4-478 processors lately that are all Prescotts. They are getting very cheap on Ebay now. Speeds range from 2.8 to 3.2GHz. All have the 800FSB and 1M cache. I'm not sure where my old Northwood 3.2GHz/512K/800 would fall in this continuum. I'm pretty sure that all of these processors are hyperthreading types, even the Northwood. I suspect that onboard RAM is about as important. I have added or improved RAM in a lot of my towers lately. 2G of DDR1 is fairly typical for me now. I have also acquired four new (to me) P4-478 mother boards. They all ended up being various model MSI boards, and all are fully Prescott compatible up through 3.4GHz with no BIOS changes necessary, unlike some older generation mobos. BTW this generation of P4 mobo is also getting very cheap now. We are talking about used pullout boards, of course. I'm aware of the increased cooling needs of the Prescotts. I bought a couple of new/surplus heatsinks that are up to the job, but am also running a couple of other heatsinks that are probably only rated through 2.8GHz or so- at slightly over rated power for them. I have seen a number of them running at around 60 deg C. Probably cooler would be better... P.S. For anyone who is keeping track, my recent mobo acquisitions are: MSI 865GVM2-LS aka MS-7037 MSI 848P- Neo V aka MS-6788 MSI 865PE Neo 2 aka MS-6728 V.1 Edited July 23, 2014 by Cluttermagnet Quote Link to comment Share on other sites More sharing options...
abarbarian Posted July 24, 2014 Share Posted July 24, 2014 Shame you are not over here as I have a luverly copper cooler that runs almost silently whilst giving great cooling that you could have had as it is not compatible with anything I am running.. http://www.frostytech.com/articleview.cfm?articleid=1359&page=2 If you see one dirt cheap it would be a good buy. 1 Quote Link to comment Share on other sites More sharing options...
Cluttermagnet Posted July 24, 2014 Author Share Posted July 24, 2014 Thanks. Yes, I'm basically aware of the superiority of copper, but those can be pricey. If I could snag one used off of Ebay at a reasonable price, I'd probably go for one. Quote Link to comment Share on other sites More sharing options...
abarbarian Posted July 25, 2014 Share Posted July 25, 2014 That version should be cheap secondhand as it is obsolete ie: It will not fit modern cpu sockets. Those of you with an eye towards upgrading should be interested to know that the Zalman CNPS700-Cu is the first heatsink we have tested so far that can be used to cool both the socket 478 Intel Pentium 4 and the upcoming socket 754 AMD Athlon64 "Hammer" processor. This means if you upgrade to an Athlon64 when it is released you'll be able to continue using the CNPS7000-Cu. The article is from 2003.
