Since everybody experiences noise differently, and a quiet, high-pitched sound can be harder to tolerate than a loud, low hum, we have provided videos including the noise of every card under full load. The relative loudness of the audio has been preserved, so the videos can be used to compare the cards directly.

Acoustic Performance After 10 minutes of GPGPU Compute (Bitmining)
HIS HD 7950 Fan (Referenz)
HS 7950 IceQ Turbo
Sapphire 7950 OC
Asus 7950 DirectCUII
MSI 7950 TwinFrozr II
PowerColor 7950 PCS
Similar to what we found in our measurements, PowerColor's HD 7950 PCS, Asus' HD 7950 DirectCU II, and HIS' HD 7950 IceQ Turbo provide the best noise characteristics.

WOW.
how is it cheating? it is cheating only if the average user will not use the "GPU boost" feature, but reviewers are using it.
and, the card is faster, cheaper and cooler than the competition. so if you are better, you cheat?
Fanboi.
But everyone who is comparing stock clock benchmarks should keep in mind that these cards most likely wont overclock as much over their gpu boost frequency as a card without boost overclocks over its stock frequency (assuming both cards have the same overclocking capability). Especially since the gpu boost on non-reference cards sometimes already is 200mhz over their base frequency.
This can make a precise comparision more difficult. Particularly if you compare cards which are very close like the 7970 and 670 for example.
also, gtx580 seems to be missing in the crysis2 charts.
As well, what kind of memory overclocks did you get? Did you have to change the voltage of the GPUs to get said clock speeds?
This article was missing a bit too much info there to really be able to get the full picture of these GPUs. The HD7970 6 card shootout is how it should have been done for the HD7950s. Each cards overclocking ability (core/memory) and what they got with stock voltage and overvolted.

You know what this is like? Imagine yourself as a concert prompter, trying to put a lineup together. You have Megadeth, White Snake, Poison, Guns -n- Roses, AC DC, you think you're doing just fine...What? Metallica wanted nothing to do with that roundup of Who's Who? Did they turn you down, or did you guys turn them down?
Because XFX matters. XFX always matter! And I'm pretty sure they weren't scared to step into the ring and beat some heads in with a comparo with the best in the biz. You guys need to get in touch with them and test their HD7950 and see if their card has the potential to blast that "elephant in the room" and hang it's head on the wall.
This is Tom's Hardware after all...
You want to add 7970 OC into the crowd ? Just ask ...

Dear Sonny73N,
Why? Because the translation is slower than a crappy GT 430

So you read the 2nd sentence of the overclocking but not the first?
sorry couldnt help myself. the fact they all hit 1025Mhz is relevant. Doing it at stock voltage is the "safe" way. and a way to show what the "average Joe" can do safely with just the sliders in CCC.
Its clearly just a puff piece for these cards and nothing to do any real comparison with when its only game benchmark is crysis 2
