hi, now that i just got done ranting about amd cpu's in the intel forum. i would like to know how many mhz can usually be squeezed out of a t-bird 750 without any major modifications. only the pencil trick. no soldering etc. only air cooling(pep 66, delta 38cfm fan).

the 750 would be the most expensive amd cpu i could afford. since i would need a new mobo also. so the only other choice is a duron. would an o/c'd duron offer higher performance than the t-bird 750?
im shure the duron will go to a higher clock speed then the t-bird 750. but will the t-bird still offer higher performance at a lower clock speed than the duron?

how do these cpu's compare clock for clock to a celeron or p!!!? ie. a 1000mhz(o/c'd) celeron or p!!! is equal to what speed duron and t-bird respectively?

what type of sisoft sandra score can i expect from what ever cpu you guys recomend?

any thoughts or comments on this subject are greatly appreciated,

thank you,
sendatooli.


p.s. if you read my post in the intel forum insulting amd. well, the k6 and k6-2 put a bad taste in my mouth. this doesnt mean i couldnt be won back to the amd side. try me.

A whole bunch of questions :)

The T-Bird 750 is not a good bet to hit 1GHz, at least not without getting fancy. 900+ is a reasonable expectation though. Clock for clock, the T-Bird will beat the PIII (as will the Duron beat the Celeron). Sandra scores will depend on what speed you reach and how you get there.
Not knowing what you will use the system for, a Duron is cheaper and you get about 80% of the T-Bird performance.

i am going to use this for audio recording. as far as i know this requires a lot of on die cache and a very strong fpu.
i will come clean and mention that i just bought a celeron cc0 600 that is already running at 1197! guess im lucky in that respect. well, my vender told me he would exchange it for a t-bird 750 or any other item in the store i can afford.
i need to spend less than $100 on the cpu to also be able to get a motherboard. the t-bird 750 is $91 there. my boxed celeron was $87. there are a number of duron choices under $100.
i guess what i really want to know is, is there a duron or t-bird that will be significantly faster than what i have just purchased.
for under $100. while i still have time to exchange this?
remember i am lucky to be at 1197 at 133 bus(bus speed makes a big difference with intel). if i could get a good t-bird to o/c for my price constraints it would be better than a duron i would gander. or will the duron at a much higher clock speed outdo the t-bird? anyways i only want to do this if i can get something way faster than what i just got.

some facts, if i get an amd. it will either be with an asus or abit board, he carries all of them. it will be air cooled. pep66 delta 38cfm fan. arctic silver. very good case cooling.
i am willing to try the pencil trick if it is necessary to do so. does the pencil trick ALWAYS work? or could i get stuck with a dud?
i am NOT willing to do soldering or mechanically or electronically modify anything. my soldering skills are fine. i just dont want to spend that much time on this. i basically want to pop it in and go.well, i will draw on it if necessary. anyways, it is my understanding that that the asus board has built on dipswitches so no mods to the mobo or cpu are required? although, i do know you need to solder to increase the voltage, but then i would require more exotic cooling. which i am not willing to get into. overclocking is fun but its not the only thing i do. so i need a system that will only take a max of a few hours to have up and screaming and will stay rock stable and not die from heat failure. the worst thing would be to have an audio recording app lock up on a clients work just after i spent the last 12 hours working on a track.

amazingly the intel is stable at this speed. geez did i luck out with this one. i havent used amd for 5+ years. but seeing as how it seems to be kicking intels butt(from what ive heard). i wouldnt mind coming back to the amd camp.
anyways i only have to friday to trade this back so any suggestions as to what route i should go are greatly appreciated.

sincerely,
sendatooli.

From what you said, you'd get better performance from the T-Bird due to the L2 cache size. Closing the L1 bridges always works but each chip is unique and there's no telling what speed you'll end up with.
Remember, CPU speed is only part of the performance equation.

tachyon, thank you for your reply. ok the only t-bird i could afford is the 750. considering i have a celeron now ,anyways, i might do better to get a duron. well since i hit such an amazing speed with my celeron i dont know what to do. you said earlier that the t-bird 750 will only reach about 950? will a duron at over a gig outperform the t-bird at 950? will i have to do soldering surgery to any of this stuff?
ok now with all that info, should i just stick with what ive got?
i will also loose an isa card that is very dear to me since the amd boards have no isa slots. this isa card is one of a kind and cannot be duplicated by a pci card.
all that said, is it still worth it to go get the amd? is there ANY amd cpu that is much faster than my cely at 1197? without hacking the cpu or mobo or fancy cooling?
if so which amd cpu should i go get today. if not ill just leave it alone. doesnt matter to me either way. i just want the fastest cpu i can afford, with the least hassle to get it there.

your reply greatly appreciated,
sendatooli.

Performance is relative...not trying to be smart here :)

A person that surfs the web, sends e-mail, etc. would not notice the difference.
A person that uses Photoshop, AutoCAD, etc will notice the performance difference by having a RAID system.

I personally believe that a system should be designed based on the expected needs of the user (and of course the wallet).

All that said...it appears that your Celeron will work for you just fine. A Duron MAY be better in that you finish a track in "x" amount of time less. A T-Bird WILL give you better performance and your work will be accomplished "y" earlier.

What x and y times are depend on more than just the processor speed...it is your total system performance. Also, only you can decide if x or y faster is cost effective for you.

I hope that makes sense for you.

tachyon, thank you again for replying. its not finishing tracks faster. the more cpu and disk subsystem power the more tracks and effects one can run concurrently. ive got the disk subsystem taken care of. these applications are intensley cpu and fpu dependent. they are even more so than photoshop.
that said, unless the duron is much much faster than a celeron clock for clock i would simply be best off to keep my celeron. being that the t-bird is much faster than a celeron that should be the way to go. especially since the t-bird 750 is only 10 bucks more than my celeron! here is the (hopefully final) question: from what ive seen the t-bird 750 will only hit about 950 with a moderate amount of work. like i stated before my celeron is running at 1197 on a 133 bus. that said, will the t-bird at 950 still outrun the celeron at 1197. if the t-bird is still faster that is what im getting. if the celeron is faster ill find my self a duron that goes over 1100mhz(if there is such a thing). since clock for clock a duron is even faster than a celeron.

in case you just muddled over this whole post just read this:

>>"is a t-bird running at 950 faster than a duron or celeron running in the 1100 to 1200 range? based on the above mentioned type of applications"<<

your reply greatly appreciated,

If the work you do utilizes the L2 cache then your only choice is the T-Bird at 900+. It may clock slower but it will perform better because of the L2 cache size.
