pentiums....the difference between them
(Click here to view the original thread with full colors/images)
Posted by: hyan
ok guys, I m looking to put together a machine sometime next month, but its been a while I've built a computer and since then it seeems intel and amd came up with too many CPUS. Could someone briefly explain to me the current CPUS and their compatible chipsets, problems/issues, relative performances and if you own one of em, what you think about itoo 
thanx

1. Don't buy a CPU from the Prescott line. I know that someone's going to post something like "compukeith doesn't know what he's talking about. Prescotts are great", but I have heard nothing but bad news. They are great as a heater though!
2. If you're going to go with Intel Pentium, get an HT processor. I have an Intel P4 2.8Ghz HT and it's amazing. That along with my memory and motherboard make my system fly.
3. I don't know anything about AMD since it's been many many moons since I've used them.
Happy Hunting!

try the INTEL PENTIUM 4 EE (stands for extreme edition) 3.2Ghz; L2cache 512kb; L3cache 2Mb; with HT-technology

I own an AMD Athlon XP 2000+ and I think it works great, I usually have 90-100% load CPU constantly and it works great under the pressure and it hasnt showed me any problems yet. I run it on an ECS K7S5A Pro mobo with 256 DDR PC-3200 RAM. I could use more RAM though. But as long as I make sure I have no spyware/adware and no unneeded services running in the background, my computer is very fast.

Intel has a naming scheme that represents the different processes and FSB speeds of their processors. When shopping for a Pentium4, you'll see a letter at the end of the MHz rating: A, B, C, or E. Your best bet would be to get the C version (Northwood core, 800MHz FSB) of the processor (if available). I wouldn't recommend getting a P4EE.. it's way too expensive to be practical

I've got a p4 2.4c with 1GB pc3200 ram. I have the processor overclocked to 3.0ghz (using watercooling) and it runs nice n cool. I had the cpu clocked to 2.75 running a bit hot, but using only air-cooling (stock intel fan).... consider overclocking if you wanna get some bang for your buck

and with 2.8 HT, im guessing ur talking about the socket 478 ver. no ?
Whats the latest socket type ?
Posted by: REv9k
It depends on what you are doing. I agree that Prescott's probably aren't the best choice, but the P4EEs are way the he11 too expensive for what they are.
If you are doing digital media encoding, Intel has historically been the best, but that's changed a bit recently when compared with the AMD socket 939 platforms.
For gaming, nocontest, Athlon 64is the only sane choice.

I disagree. There are millions of perfectly sane people who game on P4 and Athlon XP platforms all over the world.

I don't play games that much but I like running stuff at the background e.g. sql server, webserver, and opening like 20 windows at the same time. . . I'm a developer and running sql server / iis / apache kinda slows things down for my current 2.0ghz laptop.
hehe. . my mum wants a laptop so whis gonna keep mine and give me some money to by a desktop . . . and since I just got my self an ibook i wouldn't mind getting a desktop . . .
i guess im looking for a just solid and reliable machine that is pretty fast and reasonably priced at the same time (i just realized what i said was what everyone probably ask for hehe)

hmm at the moment, Pentium 4 with HT support / socket 476 looks like the best bet for me.
Could people explain to me the different letters at the end of P4's name ? .. . . why is C the best one ?

The C core outperforms for the most part all the other revisions currently. The Prescotts ("E") even though they're newer and more advanced won't prove their worth until later when they become faster. At the present time the Northwood ("C") cores are the best performing chips. The A and B cores are outdated, so you don't need to worry about them.
Take the 3.0GHz range of P4s for example (all have HT)
3.0A - N/A
3.06B - Northwood core, 533MHz FSB, 512K Cache
3.0C - Northwood core, 800MHz FSB, 512K Cache
3.0E - Prescott core, 800MHz FSB, 1MB Cache
The Prescott may seem like it has better numbers than the Northwood (it does), but the transition introduced a lot of EE jargon that can be explained fully here. Basically, the Prescott core is more advanced, but it needs more speed to be able to match what a Northwood could do at the same speed (it's said that this number is around 3.6GHz.. somewhat far off). Also note that the Prescott consumes more watts than a similar Northwood so they run much hotter.
You can search around the web for Prescott vs Northwood reviews if you want solid numbers.

wow thanx for that

so . . .whare are some good sites that allows you to compare prices on the hardwares?

www.pricewatch.com
Although I'd highly reccomend www.newegg.com for all of your computer hardware purchases.

Keith, so to have to be the one to tell you this, but you underestimate Press"hott" its like when intel switched from P3's to P4's. P3's beat them in the applications at the time. Thats how its going to be with Prescott in the future. Since apps now don't fully use prescotts pipelines, prescott seems like a bad choice. It wont be in the future.
Furthermore, Athlon 64 is the gamers choice. http://www.hardocp.com/article.html?art=NjI2LDE=
When all your cpus 3500+ and higher are coming close to or beating the P4 3.4Ghz EE, you are dominating games. Personally I buy AMD, they are reliable chips (unless you doing something stupid. IE me). And 64 bit cpus just had a 20% price drop.
Posted by: hyan
ok, im just looking at the prices of the cpu and actually amd seems to be pretty reasonably cheap now. . .
any thoughts on athlon64? and the new socket type ? what's the adv of the new socket type???
Also, what are your thoughts on pci express? is it worth waiting for it? How much faster is it than agp ? . .
Posted by: Bix VT
If you're going to buy a pc that's both cheap and fast, get an AMD Athlon XP chip and visit www.overclockers.com.
And if by "new socket type" you mean socket 939 vs socket 754, socket 939 is faster.
PCI Express is worth waiting for. It's going to be very fast, but we won't be taking full advantage of it's capabilities until graphics cards become much higher bandwidth. It's much faster than AGP, but the AGP bus isn't the bottleneck, so you probably won't notice much of a difference with todays cards. When they start pumping out newer faster gfx cards is when you'll need PCI-Express.
Posted by: Superfly3176
The basic advantage of the new socket type is, yes its faster and it uses dual channel, as opposed to S754. Im gonna hold out, until I get enough money (broke right now) for socket 939. The 3500+ is extremely tempting.
Posted by: hyan
so i think i've decided with atholon 64 3500+ since its kinda cheap at the moment . . . the prob with computer is though, when u wait for something to come out, you will never get one . . . ^^
Posted by: Bix VT
Yeah, basically the only difference between sockets 940 and 939 is that the the 939 doesn't need registered ram.
Posted by: hyan
what's a registered ram ? ? ? bah i've missed out on so much . . . . grrrr
Posted by: taco_fox
Registered RAM (also referred to as ECC RAM) is normally used in server applications. They sacrifice a little bit of speed to do error checking, so they're useful for critical server processes and such. Since the Athlon FX chips, which use the the 940-pin socket, are basically the same as Opterons (server grade chips which also use socket 940), the easiest way to get consumer motherboards on the market was to simply convert server motherboards.
This is why the transition to socket 939 is beneficial. Non-ECC RAM is cheaper and performs better, and you can get dual channel capability on an A64 instead of just the AFX.

Tom's Hardware site has excellent reviews, comparisons, and test results, as well as a link to the comparison between the Northwood vs Prescott CPU's.
