Houston, TX | 7900GS is faster than 7900GT? And cheaper?
Did I get this right from the benchmarks?

I did hear that the 7950GT is faster and cheaper than the 7900GT though.

Stock clocks the answer, as BA said, is no. You have to watch the clock speeds though because there are numerous gs and gt cards that are overclocked. Clock for clock the gt will be faster, but an overclocked gs, say 500+ core, will outperform a stock 450 core gt. |

yeap that is correct (see below). 7950GT is definitely faster but it's not necessarily cheaper. check around the web and you can still find 7900gt for cheap. i wouldn't spend money on video cards from either camp for those above $200. nvidia finally realize the need for brand new gpus as their last generation architecture's been played out for quite some time now. expect the next generation nvidia high end gpus to make an appearance early november if not soon after that.
7900GT core speed: 450MHz (stock)
7950GT core speed: 550MHz (stock) |

hey asdfdfdf: With regards to factory overclocked vid cards: I have one myself. Do you or any of you guys think that they might be binning the GPUs and putting better ones in their overclocked models? We know that the CPU manufacturers bin processors, so why not video processors?
My BFG Geforce 6800 GT OC will OC to 410, I don't know if that is good or not, but above that rivatuner resets back down. The factory OC is way below that, so I am guessing mine is clocking well and it might be due to binning. That would be cool becuase those of us who want to have cards that OC well, we could buy the factory OC's models knowing to expect more out of them...
What do you guys think?

| my old rig also had the bfg 6800 gt oc which clocked at 370mhz core speed (up from ref 350mhz). with you overclocking urs past 400mhz, you pretty much have the equivalent of a 6800 ultra. and you're quite right in that manufactures do bin their gpus, which usually results in the sudden appearance of many flavors of the same sku. |

Complicated question I don't have a good answer for. I don't have any insider knowledge about this.
Certainly graphics chip makers bin parts. How they deal with different card manufacturers is the complicated question. ATI makes boards as well as chips, whereas nvidia is not a board maker, so this affects things. My understanding is that ATI has, in the past, sold lower speed chips to partners at discounts. Being board makers I would think they have less incentive to be sending cherry parts to partner board makers, but I can't say that it doesn't happen.
With nvidia today prices don't appear to have much relation to clock speed so I don't know whether nvidia, with lets say 7900gt parts, is directing specific binned parts to specific partners or what the pricing structure is. Maybe someone else has some insight into this.
What effect that has on how far one can overclock a stock card vs. a card sold overclocked isn't clear. The nature of binning is that chips are tested to meet certain quota levels and once quotas for faster speeds are met they simply test and stamp them to meet the next level quota. So, for example, if they have enough 500mhz parts they simply test and stamp further parts at the next level, maybe 450. Getting a stock clock card doesn't necessarily imply that the card is less overclockable. The cards sold overclocked often have little additional headroom. The stock parts can often be pushed as far or farther than a card bought overclocked. It's a crap shoot. What you are buying in an overclocked card isn't the assurance of being able to attain maximum overclock, but you are only assured of the overclock that the card is specced at.
Hopefully this isn't a completely useless response. |
