Well, 4GHz i7 should be enough

But it can also benefit from a bigger framebuffer I guess.

Overclock the 5870 and yes it probably is faster. But you didn't take into consideration, that you can overclock the 480 as well.

How much do you think you can overclock that beast when it's already running 94C at stock clocks?

5870 has the headroom because it runs much cooler. Guys routinely hit 1000MHz on the core.

It would be interesting to see an OC'ng comparison between 5870/480, for sure. Has anyone found one yet?

This is what I'd like to see as well.

If there is a need for dual GPUs then there is certainly a need for overclocking high end GPUs for free performance. I see no reason for this not to be covered more thoroughly.

Firingsquad had some overclocked 470 and 480 benchmarks that showed 15-20% improvement in performance, but it seemed like something was off with a lot of their results so I'm taking that with a grain of salt.

I'd be overclocking a 480 if I bought one... but if the heat output is already as bad as it is, I don't know how its even possible to overclock.

1GHz HD 5870 vs 825MHz GTX 480

Great find. I like that they tested all games with overclocks as well.

From just a quick glance, it looks like 480 scales better when OC'ng. Two things I wonder, though--

1 - Will you be able to overclock long-term with 480 safely because of temps
2 - Could they have gone even higher on 5870 than they did. I've seen some guys hit 1050 on the core stable, and ATI allows software volt-modding to increase voltage for higher overclocks. Nvidia doesn't do this, to my knowledge.

But, nice results/testing.

**Vardant** · 03-28-10, 11:05 AM

I don't know, I think they were promising voltage changes a while back, but I'm not sure it would be a great idea

With how hot the 480 already runs, I'd not oc it. But I do see something promising here- how well it scales when oc'd. I imagine we might be impressed by the refresh or the next gen part. I think this is not a repeat of the FX5800, but is instead nVidia's very own 2900XT. If it weren't for the 2900, ATi would not have the success they now are enjoying.

ATI really could just clock the parts faster and just call it a day if they haven't already.

Wish we had some power consumption figures for the OC cards in that hwguru review though.

wishiknew · 03-28-10, 12:00 PM

This have been bugging for a while. Do those new GTX470/480 have hardware VRM protection to prevent overdraw like the 5870s?

Yeah that's the sad part isn't it. With the current thermals on the AMD cards, they could simply up the vcore and release a "refresh" which would easily put them back on top. I'm glad to see the new nV cards are doing well. Unfortunately they just aren't in a position to dominate the 6 month old AMD cards.

As far as people saying that the cards are using release drivers.....remember that chips have supposedly been available since last sept. so they've had lots of time to work on drivers.

I'm hoping that we'll see some improvements but again they've had 8 months with the silicon to work on release drivers....

I guess that semi-accurate guy was more accurate than Nvidia and it's paid forum "news" posters

That being said, this card on a smaller process with all sm's active should be quite a beast
