AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 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.
Batman ends up being the one and only test the 7870 loses at when compared to the 6970 at 1920. Most likely exacerbated due to the lack of significant digits from the built-in benchmark, the 7870 hits 59fps while the 6970 hits 60fps. For all practical purposes this is a tie, but it serves as a showcase of the lower bound of the 7870’s performance relative to the 6970: equal to, and no slower.
Otherwise Batman isn’t the strongest game for AMD’s cards. The GTX 570 takes a 2fps(~3%) lead over the 7870 here, while the 7850 does much better versus the GTX 560 Ti. Interestingly the 7870’s lead over the 7850 is extremely small here, with only a tiny 7% gap separating the two cards. This is less than the core clock difference never mind the shader difference, so it would appear we’re looking at a memory bandwidth bottleneck for the 7800 series here, which is reinforced by the 7950’s lead. In which case there’s an interesting opportunity for AMD’s partners here if they equip their cards with 6GHz GDDR5 chips in order to go for a strong factory memory overclock.

Whoops, flipped a number. Thanks!Dark_Archonis - Monday, March 5, 2012 - link
Good to see AMD providing tough competition for Nvidia.Now, when do we see Kepler? Nvidia has been taking their sweet ass time with Kepler, it's frustrating. Fermi overall is a frustrating architecture, in that it's only fast in mid-high and high-end specifications. In mid-range and low-end cards Fermi sucks, when compared to equivalent AMD cards.
Well AT, how long do we have to wait for Kepler? I hope Kepler brings a big performance boost across the board for Nvidia. Intel will only keep improving their integrated graphics, so Nvidia's low and mid-range graphics offerings need to be MUCH better than they currently are, to be worth buying in the future. This is especially true in the laptop market.

Really for the exception of 7750 witch has a really low power draw, my i will stick with my 4850 CF for now. No reason for upgrade. I mean no new demanding games and 7xxxx ati cards are just expensive.Death666Angel - Monday, March 5, 2012 - link
"Once again the 7970 and 7950 place quite close to each other, particularly at 1920. "I think you mean 7870 and 7950? :-)

For those waiting for nVidea to come to the rescue with an amazing next generation product, I would urge you not to get your hopes up. Nvidea sees their future in the mobile space creating Tegra APUs and mobile graphics and this is where they are spending their R&D budget. The desktop graphics market is simply not growing much anymore.DeViLzzz - Monday, March 5, 2012 - link
some people care about Physx so we have to wait on Nvidia lolA5 - Monday, March 5, 2012 - link
Why? There's like 2 games that use it.CeriseCogburn - Thursday, March 8, 2012 - link
There's actually like 2 hundred, but keep drinking the radeonaide.SpaceRanger - Monday, March 5, 2012 - link
The lacking of WHQL Drivers has me shaking my head. Come on AMD. It's been 3 months and you STILL can't get a WHQL driver out for the 7xxx series!

if you already have a 560 Ti I guess you hope for another price drop on the cards so you can SLI themif you can get your hands on an affordable used 6970 or a new Power Color 2 GB 6950 and flash it to a 6970 then do so
