How good is the GTS285 1GB

Been offered one of these cards but I have not been up to date with GFX tech these days. I would like to know how good this card is - I have twin Radeon 4870s just now - where is it in comparison to these as far as performance goes?

Anyone got a link to a comparison chart?
 
2x4870's will be significantly faster than a single 285gtx, the only upgrade for you is really a 5970, 2x5850 or something along those lines.

Two old gen gpu's generally won't be far off the performance of a single new gen gpu as they tend to roughly double in power.

2x4870's probably match a 5850(though it has a heck of overclocking headroom) and is probably beaten by a single 5870 but not by an amount that would really be an "upgrade" to what you have.

You'd pretty much need to go for a xfire setup of any kind to see a big upgrade in performance and a 285gtx would be a noticeable decrease in performance.
 
I am not looking to upgrade my main rig - this is for another computer and I am trying to gauge how well this performs thats all guys.

In that way, I will decide whether it is worth getting - is it as good as a single 4870 ?
 
Its better than a single 4870. Around 10-20% I would think as the 4870 is equivalent to a gtx260 and the 285 is its bigger brother.

AFAIK, the only GTS card in that family is the G92b based GTS 250.

The only card with the 285 numbering is the GTX 285. This is a good card and a good chunk faster than a 4870 - but isn't nearly as fast as two 4870s in crossfire.

This and this review compares a GTX 285, single 4870 and 2 4870s in crossfire (or 4870X2 which has practically the same performance).
 
yep, if its a 285 it will be a gtx which is a fair bit quicker than a gtx 280 and that is no slouch. The GTS cards were cheaper cards and less powerfull, theres wasn't ever a GTS 285 though.

How did you work that out ??


I thought the 285 was just a more energy efficient version of the 280 with maybe a few more smaller changes, speedwise they were much the same.

I went from a 4870 to a 4870x2 to a GTX 280 and between the latter I couldnt tell much difference apart from the 4870x2 could turn bread into toast.

If you look at the benchmarks I linked to in my last post you will see that the GTX 285 is fair bit quicker than the GTX 280. Its not a massive jump, but there certainly is a performance increase along with the die shrink.

the 280 uses a 65nm die and the 285 a 55nm so yes less voltage and less power usage but that = faster clock/shader/memory speeds and generally a 10% boost in performance over the 280.
Twin 4870s are still going to out perform the 285 so I would probably give the 285 a miss unless you want less heat and less noise.
