866Mhz vs 2.8Ghz

[Smithyoffline]

I would just like to know how much better would my new system be compared to my old system.

 

[Megatomic]

Lots.

it's almost impossible to quantify . . . . and depending on what you are going to use it for, it could be anywhere from simply "more snappy" to 5x faster . . . . if you just use it for email and word processing, dont bother. but if you game or do anything intensive, im sure you would notice the difference

r u talkin pentium or amd b.c there is no amd chip for 2.8 ghz DONT BE FOOLED by 2800+--- not the same thing!

 

[txxxx]

If just general day to day desktop, its not as noticeable, but it really does depend on what you do.

uh no, but the same performance. that tbred one anyways

Fooled.... riiight

It's not only the processor. You could take a 2.4ghz PIII (theoretically, let's say such a thing existed) and compare it to a P4 2.8C and the difference would be light years apart. This would be due to the fsb, dual ddr (or ddr by itself for that matter), and a multitude of other factors.

 

[dullard]

I'm assuming you are comparing a 866 MHz PIII to a 2.8 GHz P4. For CPU limited programs, there would be slightly under a 3x increase in speed. I say under (even though 2.8/.866 = 3.23) since benchmarks show over and over again that even with 800 MHz fsb and HT, the P4 is less efficient per clock than the P3 was. Now that is an average. Some programs (like content creation) will be above average and some will be below that average.

That is for CPU limited programs though. If your video card is limiting, it won't matter much what you have for a processor. Same goes if the keyboard is limiting (many programs like Word), or memory is limiting, etc. In these cases you'll see far less than a 3x increase.

Actually a 2.8ghz P3 and a 2.8ghz P4 wouldn't be too far apart. Despite the slower FSB and RAM, the P3 had better performancer per clock cycle compared to the P4. The P4 was made in mind to scale very high Hz wise.

Good luck trying to clock a P3 to 2.8GHz though

Yeah. The whole reason for the P4 was to clock higher, since with the P3 they were beating a dead horse.

People upgrade from a 1.8gz P4 to a 2.8ghz P4 and are happy with the performence boost...I think you will not look back!

 

[firewall]

I agree with dullard

 

[So]

as do I.

what do you mean fooled? AMD's PR rating was never ever meant to be compared to the P4. In the beggining it was very close to that so people thought that is what it meant. The athlon xp pr rating is made to compare it to that ghz of an athlon thunderbird. And there are still many tests that the pr rating is accurate. In buisisness stuff ,the 2500 is faster then a 3.2ghz p4, and athlon xp is still king in general usage performance. Dont be foool heheh. It is very real. The Athlon XP, why it may not be as high of clocks, it is very efficient. So ust becasue of some benchmarks, and the fact that is it lower clocks does NOT mean that it is a fake pr rating. The 3200, is a little far fetched in the pr rating though. Most everything else is right on.

 

[Goi]

I seriously doubt the Athlon XP 3200+ or 3000+ are as fast as a Thunderbird 3.2GHz and 3GHz respectively. Nothing much has changed between the 2 cores other than the addition of more cache and SSE. Besides, its kinda silly comparing an Athlon XP against a non-existant chip. Even AMD themselves would have no idea how well a Thunderbird 3.2GHz would perform since it doesn't exist. Obviously Joe Consumer's gonna take the PR and compare with intel, and AMD knows that.

Smithy ... the new one's going to be better off than the old one no matter what criteria you use... including noise level, heat generation, and power consumption, unfortunately.

If you are surfing the web and sending out email, I doubt anyone would see the difference. If you're rendering a 90 minute AVI file to MPEG, you'll save about 4 to 6 hours ! For everything else, the answer would be - it depends!

 

[chilled]

I upgraded from a PIII 866 on a MSI Via Apollo Pro 133A board to a AXP 2700+ on MSI nForce2 board - the difference was as clear as night and day, particularly since the only component used in both PCs was my 32MB GF2 GTS.

Booting up was quicker with my newer HD, windows was snappier, video encoding was quicker and even games were smoother (3d Mark increased from 3300 to 5600 on a oc'ed GTS).

So, get the 2.8GHz (or even a 2.4C to save some dough) and get a good i865/i875 board to boot.

Well this seems easy enough...it is 2000 more mhz. Of course it would be faster. And if you game or edit video, photos, audio then it would be night and day...

According to the intel ads, web pages will all turn 3D and download 3 times as fast.


As stated above, it depends on the application. For games read this comparing 1 GHz to 2700+

 

[HokieESM]

It depends. The ultimate engineering answer when you don't want to answer the question.

What HDD is in your current system? What video card?

I'm posting right now from my "quiet" file server--which is a 1.4GHz Celeron Tualatin with 512MB of PC133--but it has a modern 120GB HDD with 8mb of cache. I'm currently doing some serious computation on my P4 2.53GHz with 1.5GB of PC1066. The P4 is indeed much faster at computation than the Celeron.... BUT for copying files, burning CDs, posting on AT, and doing office productivity, I can't tell the difference between the two.

But if you're thinking just about gaming performance (as appears to be the norm around here), there will be a DRASTIC difference. Make sure the P4 has a decent video card: most of the modern cards are showing SERIOUS scaling with processor speed.
