AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 AM ESTBattlefield 3
Its popularity aside, Battlefield 3 may be the most interesting game in our benchmark suite for a single reason: it’s the first AAA DX10+ game. It’s been 5 years since the launch of the first DX10 GPUs, and 3 whole process node shrinks later we’re finally to the point where games are using DX10’s functionality as a baseline rather than an addition. Not surprisingly BF3 is one of the best looking games in our suite, but as with past Battlefield games that beauty comes with a high performance cost
For anyone keeping score, we reran all of our numbers after the recent Battlefield 3 Radeon HD 7000 series performance patch. The results are virtually identical. While we don’t have official confirmation, we believe that DICE switched to a different FXAA codepath; however doing this doesn’t seem to have impacted the performance of the 7000 series, which is either a testament to AMD’s shader compiler, or proof that the overhead from FXAA is very low in the first place.
In any case while AMD’s BF3 performance has improved since the 7970 launch, it’s still one of their weaker games. The 7870 can hang with the GTX 570 at 1920 but the 7850 once more falls behind the GTX 560 Ti. The 7850 in particular just isn’t doing very well here, and it would be necessary to drop down in settings or in resolution to get fluid gameplay out of BF3. However at the same time we do see some further evidence of the impact of having 2GB of VRAM, as both 7800 cards improve relative to NVIDIA’s cards at 2560.
Meanwhile compared to the 6900 series, the 7800 series takes another small lead. At 19x12 without MSAA the 7870 has 5% on the 6970, while the 7850 is effectively tied with the 6950. It’s interesting to note however that relative to the 7950, the 7870 is doing very well here, trailing AMD’s faster card by less than 4%. The fact of the matter is that with the same basic frontend and the same number of ROPs, the 7870’s 1GHz core clock can significantly eat into the performance lead of the 7950 if the 7950 is primarily performance bound by either of those two rendering stages.

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
