x1600pro 512mb question

post #1 of 6
Thread Starter 
I've just bought a x1600pro 512mb to replace my old agp geforce fx 5200 (I've only since recently gotten into gaming and my computer was put together around 3 years ago). Anyways, after looking through the forums for a bit, I've found a few threads saying that the x1600pro can't utilize the 512mb due to the 128-bit mem interface. I'm just curious what this means (sorry for being so broad) and was it still a better buy than the 256mb version(performance wise)? Will this upgrade also increase my luck with games such as CS:S even with my outdated computer?

Well that card has 512mb ram right!! it only has a 128mb Ringbus bandwidth so it can only really process 128mb bandwidth at anyone time and not 512mb.

actually what is happening is that every second that vid card can only send 128bits from the mem to the core. The memory can get full but the information inside sits there longer than if you had a 256 bits. In real life performance that extra 256MB of memory isnt gonna help much because all your doing is making the data stop for a few seconds then preceed to the core. If you had 256MB the data would either not wait at all or stop for much shorter period of time. i hope this helped.

oh and by the way contrary to what the previous post said NO vid card has 128MB bandwith. its actually 128 bits.

8 bits=1byte
1MB=1000bytes

Also some x1600 has a new ringbus that even though its sold as 128bit it works like a 256bit, not sure if they changed it but look up reviews of the x1600 and you should find an explanation of this. As far as the card using all 512mb of ram the other guy is right, especially on an AGP bus, your card would be hardpressed using 256mb ram on 256bit interface, 512 is really a sales gimmick, but that doesn't mean you card isn't anygood. Performance wise its one of the best AGP cards out now (excluding nvidia of course) that supports sm3.
