I'm considering a new card...but I do not wish to name the contenders here because than many irrelevant aspects can come into consideration, so I would like to ask the question in purely technological terms.
Consider two cards: they both have 8 pixel pipes. They both have the exact same GDDR3 memory of exact same 2.0 latency, both Samsung.
Card A has:
- 3 vertex pipes
- higher default clocks 500/900 and can be securely overclocked to ~550/1100 (and maybe even a more) for everyday use.
- has 128bit mem interface and 128MB of video mem
Card B has:
- 6 vertex pipes
- lower default clocks 425/800 and can be securely overclocked to ~500/1000 for everyday use.
- has 256bit mem interface and 256 of video mem.
Card B is slightly more expensive (about 20%), but as the amounts are not huge, the price difference is not really big in real money.
Which one would be theoretically better ? Are the higher speeds and overclockability more significant/important than the higher memory interface and more memory quantity ?
Exactly in which situations in real life applications (read: games) would the better interface and more memory come into account ? And in which situations is the higher clock/memory speeds more important ?
Thanks for any advice and comments.
