****Official 6850/6870 Reviews thread****

[setter]

From where I'm sitting the 6870 is about on par with a 470 give or take a few FPS, but overclocking looks to be poor so the 470 will easily out perform it when clocked.

Thats what i was thinking, probably go for the 470.

 

[Broken Hope]

plus the 470 has better dx11 performance, more features and memory and is cheaper. i say the 470 is still a no brainer.

That's weird considering the 6870 beat it in both Dirt 2 and Metro.

Nice to see the asus cards have voltage tweak, probably be able to flash other stock cards witht he bios if they dont support voltage tweaks.

I'm going by OCUK and Guru results, they couldn't break 960 on the core, now that may change if we can up the volts but the 470 looks to be the better buy if you intend to overclock, no overclocking then the 6870 maybe the better buy depending on where you regard physx and 3D vision in the grand scheme of things.

Cainer supposedly has 6870s for testing.

Cards are up now

Asus were really going for it with that 13MHz OC on their 6870

Not interested in physx tbh, definitely will be oc'ing, didnt bother with my current sli setup as the heat would be a bit much.

By quick review, i'll have two voltage tweak 6850s

Between SLi 470s and 480 performance for £300

 

[Squakingcow]

If they scale well with voltage and the coolers can cope with it there is still a chance that these cards could redeem themselves in terms of overclocking.

 

[RavenXXX2]

Yeah if you overclock go 470, if you can hit 800 core you're looking at 480 performance.

 

[Broken Hope]

Is anybody else seeing that 6870 xfire is faster than even 5870 xfire though the 6870 is a slower single card? hmm

5870 CF scaling : 67%
6870 CF scaling: 93%!

Bring on Antilles.

EDIT: 6850 CF looks good!

Considering Antilles will have 4D shaders and such, performance should be much more impressive.

LOL.

 

[crisbduck]

Any benchmarks in render tests?

Roll on saturday, wages should be cleared into the bank so i can get it ordered, then sell my 275's.

Does not make sense when you read your previous post:

What fps gain do you expect from overclocking the 470? Give or take a few... Meaning that it's a pointless argument. Plus not every GTX470 is an overclocking beast. Plus you have to tweak the voltage on it to gain higher overclocks. We'll have a tool to overclock 6800s with voltage tweak soon enough to find out if they overclock badly.

plus the 470 has better dx11 performance, more features and memory and is cheaper. i say the 470 is still a no brainer.

Does not compute with Guru's review? Both Dirt 2 and Metro 2033 work better on 6870.

That 460's overclock by 25-30% and 68xx's only manage 5-7%, I think the 460 is still a solid card, especially at it's new price. Perhaps ASUS or MSI will release a "Voltage Tweak" edition which will hit 1050-1100MHx, but until that happens I am underwhelmed.

Good cards at stock. Poor when overclockeed.

 

[Broken Hope]

What I found odd was even the 6850 beat the 5870 at Farcry 2, I wonder what changes they have made to allow that.

 

[Rroff]

You have a very high chance with a GTX470 of getting one that will overclock to stock GTX480 performance atleast - you'd have to be pretty unlucky not to - and a good clocker can do even better.

Given the current prices - unless the prices on the 6 series come down or your really really worried about noise - the 470 looks like the better buy.

6850 oced was almost 16%. Granted not the 30% of the 460s but not 5-7%.

Yep, seen a few examples of the 470 clocking to 480 levels, looking forward also to having a bit more room in the case.
