More pipelines or more Mhz?

[Albaba]

Ok which card would perform better...

Card 1: 12pipes 500mhz core/1000mhz mem
Card 2: 16 pipes 400mhz core/980mhz mem

Bear in mind that card 1 has already been overclocked in the factory and card 2 can probably be clocked at least 50mhz faster.

Thanks

Assuming that 12pipes has 12 ROPS, 12 texture units, 12 pixel shaders, and a 256bit bus and the 16 pipeline card has 16 off the above, then the theoritical numbers would be:

Card 1
------
Bandwidth: 32GB/s
Texture fillrate: 6Gtexels/s
Pixel fillrate: 6Gpixel/s

Card 2
------
Bandwidth: 31.36GB/s
Texture fillrate: 6.4Gtexels/s
Pixel fillrate: 6.4Gpixels/s

So, the numbers say card 2. Add to that overclocking headroom, then card 2 looks more attractive. If it has 16ROPs aswell be better with AA, AF and HDR too.

Thanks m8 i thought it may be the better option.
The 2 cards in question are:
Card 1: HIS Excalibur ATI Radeon X800 GTO ICEQII TURBO 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail (RX800GTO-256ICEQT) (GX-044-HT)

Card 2owerColor ATI Radeon X800 GTO16 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail (GX-055-PC)

Another question.. is the GTO16 an r480 core?

[Fx-Overlord]

Googling says that the GTO16 is only an r430 core and the GTO is an r480 core.

If the GTO unlocks, it might be another consideration, as it is a bit cheaper than the GTO16

The GTO16 won't clock as well. ~430-450mhz I suspect. My R430 X800 bravo can't get past 455mhz to 460mhz.

HIS won't unlock either. I reckon they'd be about par, when clocked to their highest possible speeds.

on now throw a 6800gs in to the frame and what would you pick just out of interest

 

[Mr Paul]

Get a Sapphire GTO2, R480 core 100%

 

[Fx-Overlord]

I thought sapphire have stopped making GTO2 with r480 cores, but are now instead usin g r430 cores.

The GTO16, for all intents and purposes is a X800XL, and you will see its pretty close to the 6800GS. I would recommend you look at the 6800GS reviews and tailor your needs according to the games you play, and the IQ level you prefer.

 

[Albaba]

Yeah thats what i heard, is the sapphire still the r480 core? If it is its obviously the best choice, to unlock then clock up.

Hmmm descisions descisions!

Baba

Edit**
Just out of interest lets say i get the sapphire. Is there an app which will tell me what core the card is using? Say the 430 or the 480?

 

[ACESHIGH]

It appears there are still R480 core GTO2 cards available.
But a mate of mine has the PowerColor ATI Radeon X800 GTO16 & has clocked to X850XT PE levels.

So its a tough choice.
Maybe get whichever is cheaper.

 

[Mr Paul]

There are R480 ones out there, its a case of finding them
