512mb or 1g ati radeon 4670

Post by seraphy » Sun Mar 01, 2009 3:33 am

so my heading basically says it all
i'm getting a ati radeon 4670 but cannot decide on 512mb or 1g
its only a $30 difference between the two but i'm just curious ..
would it really be beneficially as i heard 1gb graphic cards basicaly do nothing or only a tinny increase in performance.

Your thoughts?

Thanks

Unlikely to be worth going 1Gb. In some cases they use crap memory on these cards which is best avoided.

128 bit memory buss already is bottle necking for the 512mb card, so 1 GB version is useless...

Go with whichever is cheaper and/or

Wait for RV740 based cards to come out in a couple of months. Launch is supposed to happen in April 2009 so it isn't too far away.

If you want to spend $30 and maximize benefit, get a 4830 instead.

1GB of memory on a card with a 128-bit bus is purely a marketing gimmick. I agree with other posters, get a 4830 instead or wait a month for the 4700-series cards to come out.

In case of 4670 there is no question - 512MB. 1GB version actually uses slower clocks, and for a task that would need 1GB, you will not have gpu power or bandwidth anyway.

4830 is an option, but it consumes more power.

1GB of GDDR3 RAM on a 128bit bus? Whoever does that should be sued for false advertising. You cant use more than 512mb on that bus.

You can if you are doing CAD.

pci cards from the 8 years ago had 1 gig ram on them and cost like 1500 dollars.


4830 does consume more power but get the MSI OC one and not have pull as much. I am like the MSI oc fairy *twinkles a silver stick over your head* Look up stats online about it.

yeah if you're looking at speed, that $30 spent on a 4830 will get you a much bigger increase than the 1gb of ram, which will have a negligible to non-existent benefit.

heck stretch out another $10 or so and you're looking at a 4850!

Memory speed matters more than capacity. Even 256MB is not too limiting and 512MB is plenty. I would get a GDDR4 equipped 4670 since they don't have one with GDDR5 yet.

1GB on a 4670 might be helpful for a three way Crossfire setup, but your money would be better spent on a single faster card like the 4870 then on three 4670s.

4850 is really power inefficient and hardly has THAT much of a benefit over a 4830 OC msi. I say the oc msi as its built 900x better and gives a little bump in speed too.
