Sapphire HD 6970 Battlefield: Bad Company 2 Vietnam reviewed - 9. Overclocking; Thermals; Noise; Consumption

Review: Gift game included


Overclocking

Overclocking capabilities of Sapphire HD 6970 Battlefield: Bad Company 2 Vietnam is comparable to most other HD 6970 cards. Reference GPUs run at 880MHz and we managed to push it by another 65MHz, to 945MHz. Our overclock involved Sapphire TriXX tweak utility but since the card does not support voltage tweaking, TriXX's voltage sliders were unusable. We used auto fan rpm throughout the test.

Noise.

Unfortunately, we can't quite say we liked the card for its silence as our overclock, modest as it was, made it go really loud. The fan occasionally went so fast that it really made for pretty uncomfortable sessions.

Without overclocking, Sapphire's HD 6970 Battlefield runs normal - the fan is not quite inaudible, but it's not loud either. When idle, the card remains pretty quiet



Thermals

GPU temperatures remain in normal limits and won't exceed 89°C. Our overclock pushed the GPU to 92°C. You can increase the fan rpm and lower the temperatures to below 70°C, but we chose not to test that scenario - the card was simply too loud.

Power Consumption

Radeon HD 6970 consumes around 22W when idle, which is a few W better than GTX 570. Compared to the same card, maximum consumption is also better by about 10W. Of course, Sapphire's card is no different than the reference card so its consumption is basically that of the reference card.

Compared to the GTX 570, which is currently the more affordable deal


Yes it is more afforadble. You save 10$ which is a huge 2.8% price difference. :eek: (calculated by using Newegg numbers)

Why do they use this stupid stock-cooling for high end cards, its a shame for actually a very good card to have such crazy temps and noise.

Who sad stock-cooling is bad?!
In this case it is very nice solution - more than that it lucks like an old stile but equip a Vapor Chamber technology like Sapphire Vapor-X design!
And a big "+" is that turbine eliminate hot air out of the case!

This one is pretty bad, check the temps, 90°...and its not even quiet

Agreed, but in this case Thermal design point needs a Phantom cooler!
For the other part such a top class chip is smiling on 100'C, not a problem

But why having 100° if it lowers the life span and its very possible to have 80° or even 70°
+ almost no noise

Phantom, Twin Frozer, etc, etc

its a high end card for high end price, with mid class cooler :/

just buy a 2gb 6950 flash bios to 6970 and buy Bad co 2 on steam for 10 bux when they have a sale, which is all this week. CHEAP as hell!

LOL, the card is designed to take the heat, so no it won't diminish it's life span. NV's Fermi on the other hand is a different story, that card will die in a matter of months especially when cooking eggs on it.

Its the same silicon, and extreme temps are not good for it, besides that it heats the other close components too. This "designed for high temps" was the bs NV said and not AMD btw ^^
