HD5970 Reviews

[Wesker]

Thats still 4x aa

I always question reviewer's methods when they don't test high end video cards with 8xAA. Heck, I run my 4890 with 8xAA in as many games I can (bar Crysis).

I think the lack of testing at 8xAA has shown the HD5000 series to be quite underwhelming in a misleading way. As you can see in the benchmarks above, at 8xAA the HD5970, HD5870 CF and HD5870 really shine (which is amazing when we consider them to be "bandwidth contrained").

[annihilat0r]

the problem is that there is no significant difference between 8x and 4xAA unless you're playing on 640x480

GDDR5 is wonderfull, & ATI's AA algorythme need low amount of Vram.

With same quantity of ram onboard with 4x-8x AMD win about memory, if buffer need a bit more than on board memory on nvidia, speed on nvidia fall down quickely. On ATI's boards memory usage of AA is low, and many time don't use less the whole memory, and in this case, the gpu can easily AA with a very low loss of perf.

I play evry source games with my 5870 on a 24" with evrything maxed out, including AA8x over 100fps and i love this ^^

Can you post lost coast benchmark please.

4870 already did that

idk i just cant believe the 5970 has less power useage at load then the 295 in that review(or in some others also)

Oh, i dont know maybe because its got a pair of 40nm GPUs?

its suppose to have a 294W TDP, so if its using alot less than that, then they have alot more room for real TPD

ATI Radeon HD 5970 Overclocking Problems
Today we had planned to show you how the Radeon HD 5970 performs when overclocked. However the more we began to play with the Radeon HD 5970 the less likely that article seemed possible and instead we began to head in another direction, which lead us to this article “ATI Radeon HD 5970 Overclocking Problems”......

[Loque]

can anyone explain why a card so powerful only comes with 1gb of usable memory ? and its to be used with very high resolutions so I guess it should even have more memory for that ?

I'd hope to play gta4 with maxed out settings for example, and that requires more than 1gb...

future games won't use more than that or what ?

Terrible article. Furmark is as unrealistic of a 3D test as it gets. That is like testing IntelBurnTest and claiming that a CPU on the stock cooler runs too hot. Good to know though, HD 5970 requires waterblocks or chilled air

Whats the deal guys?
Have all the other preview sites failed to notice this alarming down-clock issue?

some of us here already got their hands on a 5970. Could you verify that at stock speed please?

[Chickenfeed]

All 5 series cards can have this problem as unlike the 4 series ( which could could burn out under furmark ) they have a mechanism in place to protect the gpu / vregs from being overstrained.

However as mentioned, quite simply the load furmark can apply is beyond that of any game and AMD simply didn't design these boards/cooling solutions to handle these types of sustained loads. I personally wish they could, but as far as the reference design goes, our hands are tied. Higher performance cooling solutions will certainly help but ideally we will need to see a 5970 with a custom PCB and waterblock to really see them shine ( and not burst into flames and sound like a 737 taxiing in process ) Myself, I won't consider a 5970 running on air.

[grimeleven]

(the review) What a noob.. he expect a good overclock with that stock cooler? I guess AMD should also have said "You need proper cooling..." as to tell what enthusiast must already know... And wtf about Furmark, everyone knows it puts GPU's in a unrealistic load, it is clocking down as a measure to not fry the card (dumbass) how about he take proper time for a review than throw this at us and tell readers see it as a bad overclocker. In the furmark SS you can see the card clock to 550Mhz as to reach a approx 100celcius, give it a waterblock or something and i really doubt there's gonna be any downclocking.

@grimeleven 5970's stock cooler is very good its max tdp dissipation rate is 400W. The thing is based on vapor tech and thus is an excellent cooler in itself.

Very good is relative, it's a very good cooler for a 5870. For the 5970 it's decent, even anandtech said they couldn't replicate 5870 CF speeds without instability and crashing. So for it's designed task of cooling the 5970 it performs ok.

It might be, but running @ those temps ain't gonna give any good OC, 1 fan for 2 GPU's no matter what tech they got, it's gonna run hot like hell because the fan will put GPU0's heat into other components. Yeah it's designed for stock speeds cooling.

[Diverge]

So when is AMD actually gonna start selling videocards? Anyone else getting tired of manufacturers launching new products that don't exist?

How long ago did 5850/5870 launch, and you still don't see any in stock... same for 5970. People should stop giving products so much attention when the manufacturers can only bring a handful to the public for their launches.... and months later. Not only does this cause unnecessary hype, it causes price gouging by etailers.

[OutSider]

omg are you not aware of tsmc yield problems?

[Crazystang01]

Supply and Demand + Yields If want a card stake out a etailer or many etailers watch restock dates or preorder. Be fast on the order if get a chance to order. That's the way I got my XFX 5970 last night on newegg.

such a horrible article. they completely forgot that ATI added a feature to prevent the card from killing itself in synthetics like furmark. and somehow never tested to see the total power draw of using such a benchmark. its not hard to plug in a kill-a-watt meter and look at the numbers before and after. (who wants to be it was near or over 400W)

Not horrible IMO. Sure, using FurMark is unrealistic but the majority of HD 5970 cards ARE very poor overclockers at their stock voltage and above.

theres a difference between getting 20MHz at 1v and 100Mhz at 1.15v

and what they are saying which these cards are only stable at 550MHz (trying to point out that they dont believe these cards can even run at 650MHz)
