AMD Radeon HD 7950 Review Feat. Sapphire & XFX: Sewing Up The High-End Market
by Ryan Smith on January 31, 2012 9:02 AM ESTBatman: Arkham City
Batman: Arkham City is loosely based on Unreal Engine 3, while the DirectX 11 functionality was apparently developed in-house. With the addition of these features Batman is far more a GPU demanding game than its predecessor was, particularly with tessellation cranked up to high.
With Batman the 7950 continues to lead the GTX 580, though not by as great a distance as we’ve seen in other games. At 2560 it enjoys a 6% lead, while at 1920 that lead has been cut in half to 3%. Interestingly, Batman is the opposite of Shogun when comparing the 7950 to the 7970: the 7950 is closer than average here, indicating that Batman is limited by something derived from the core clock, likely the tessellator judging from what we saw in our 7970 review. As a result overclocking is also particularly effective here, with the XFX 7950 trailing the 7970 by only 2% thanks to its identical core and memory clocks.

page 4 states that the clocks of the OC 7950 are the same as the shipping clocks of the 7970 (so the cards only differ by the shader units) which isn't true as the reference core clock of the 7970 is 925Mhz, not 900Mhz.Now that's only a 3% difference but given the performance difference from those OC 7950 to 7970 often ends up only being ~5% this definitely is significant.

When will the actual cards be available for sale?I've just checked Newegg, Tiger Direct, Micro Center, Fry's, and Amazon, none of them have the 7950 listed.

I feel like I'll be waiting forever for a $250 28 nm part (whatever that may be...)casteve - Tuesday, January 31, 2012 - link
Thanks for the review. Looking at the Sapphire card, it's a 30%+ speed bump over the 6950 for just 13 watts more power. I look forward to the 78xx and the GTX 6xx this spring and more reasonably priced mid-ranged gaming cards.Articuno - Tuesday, January 31, 2012 - link
That's why the 7950 is so absurdly expensive. The 5850 was miles ahead of anything nVidia had when it launched, and remained miles ahead throughout the entire first Fermi generation, yet it was launched at a very affordable and acceptable $259 price point.Despoiler - Tuesday, January 31, 2012 - link
I'm not sure what kind of fantasy land you are living in, but the 7950 beats the 580 in everything. It's priced at $450, which ~$17 is cheaper than tier 3 PNY 580 cards. Most 580 cards sit around $500. Why should AMD price the 7950 at $250 and make zero or likely lose money? AMD has better cards. They are actually charging what they should be charging. It was a complete blunder to launch the 5850 and 5870 cards at the prices they did. The only saving grace is they likely converted a lot of Nvidia buyers. The 5850 was my first AMD card and I'm not likely to go back to Nvidia with my bad experiences with their card makers.AnandThenMan - Tuesday, January 31, 2012 - link
Is it true that you did not update the BIOS on the XFX card as per emailed instructions from AMD? According to Hardwarecanucks.com retail versions of the card have an updated BIOS that review samples sent out did not.Ryan Smith - Tuesday, January 31, 2012 - link
We're using the latest BIOS from XFX, 015.013.000.010.000705.http://images.anandtech.com/doci/5476/XFX.gif

Thanks. It looks like the XFX is just too damn loud, I'm finding their stuff is quite sub par lately.AnandThenMan - Tuesday, January 31, 2012 - link
Page 3 of this thread, no BIOS version is given however.http://www.xtremesystems.org/forums/showthread.php...
"Basically, XFX emailed all media days before launch stating that their retail cards had revised fan speed profiles that allowed for slightly increased temperatures but kept the fans MUCH quieter. They sent us all a the retail BIOS file with the proper speeds. What you see above are the differences between the beta and the final release BIOS"
