Bottle necking

[Method]

yeah i mite have spellt the thread title wrong but who cares.

Does anyone have any idea of how fast of a cpu youd need to make a geforce fx nv30 bottleneck your system (btw you have unlimited mem bandwidth ect)

And how fast of a cpu would you need for a ti 4200, 4400 and 4600?

depends on what you use it for.

obviously a geforce 4 ti is wasted on a P3 500 but to lesser extremes it can be very subjective.

BF1942 for example tends to be quite cpu intensive whereas UT2003 is more gpu dependant.

but generally speaking and imho, an XP1600+ or better will not bottleneck any current graphics card. and if it does, stress the graphics card more by cranking the AA/AF :p

so i reckon these are approximately the reasonable minimums to reach most of your graphics card's potential:
GF4 Ti4200: Athlon/P3 1ghz
GF4 Ti4400/4600: XP 1600+
Radeon 9700: XP 1600+
GF FX (estimated): XP 2000+

as for making a GF FX bottleneck your system.... thats kind of impossible until software is available to stress it. a bottleneck doesn't matter when the water's only trickling ;).
but at a guess i'd say P4 ~4.0-5.0ghz

Oh, I dunno about that: turn on full pretties (AA AF etc, at high res) and even a GF FX may chug on the data a 2000 class CPU could throw at it

With the 9700 from the reviews I've seen... the more cpu power you throw it the higher benchies go.. ie: the gpu is not limiting the cpu...

[Oh-Sigh-Ris]

i agree with Ragnor.

its almost pointless getting a Radeon 9700 PRO for anything less than a 1.8 GHz rated CPU because of CPU limiting the GPU. Even on a 3.06 GHz P4 the 9700 PRO hasn't reached its peak.

This statement holds true for all video cards, even TNT's. Sure it will be diminishing rates however. Eg, a p4 with a TNT will score higher FPS than a 500MHz CPU with a TNT, but only by maybe a few FPS.

A GeforceFX thrown in the same machine as you have stated will achieve a higher FPS, so then you could say that the Radeon 9700 is the bottle neck not the CPU.

Its like surveys, you can make them say just about anything you want.

You could say that your RAM, Video card, mobo, HDD and CPU are all bottlenecks and it holds true, it's just a matter of determining which one is creating the biggest bottleneck. When you fix that, you still have a bottleneck, just something different.

I agree, but if Ihad an XP1600+ and a Geforce2MX, I's still get a 9700 cause I'd still probably get higher FPS than updrading the CPU and getting say a Ti4600 for the same price. Maybe, maybe not.

yeah just wondering if i should get a fx or ti4600, ive got a 1800 xp but i mite upgrade when cpu prices come down, they cme down pretty fast and become pretty cheep opposed to gpu's so yeah.

[must kill Dell adguy]

In my opinion:
you could wait and sell your XP1800 on trademe for 150 bucks easily ( sell it like a week or so before the Barton is released in NZ).
...then sell your VGA card (Geforce2MX is it???), I managed to get 75bucks for my MX200 (32MB) a couple of weeks ago.
That should put you up to $225, by then the XP2200+ (t-bred B???) should be about that price, and you can buy a Ti4600 for about 400/500 bucks.

i have a 1800 xp and its clocked at xp2000 speeds, i dont see any need to upgrade my cpu actually.

I think il get the new maxtor 120 gig 7200 8mb cache ata 133 hdd to replace my maxtor 40 gig 5400 rpm 2mb cache, im sure thatl speed up my system alot (that is the fastest hdd out there part from serial ata ay?)

Also will all the Maxtor Diamond Max Plus 9 8MB Cache hdd's run at the same speed?

60GB IDE HDD FDB, Ultra ATA 133, 7200rpm. 8MB Cache
80GB IDE HDD FDB, Ultra ATA 133, 7200rpm. 8MB Cache
120GB IDE HDD FDB, Ultra ATA 133, 7200rpm. 8MB Cache
160GB IDE HDD FDB, Ultra ATA 133, 7200rpm. 8MB Cache

because they are abit expencive, maby il just go for the 60 is its just as fast but i think soimeone said that from 120 gig's onwards there faster or somthing like that.

I guess my gpu will have to wait. i dont think its as important.
