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.

Yet if one is not running gigantic resolutions, they look at the usual, 1920 and 1650 p resolutions, and likely want to crank all the eye candy to the limit, which is still IMPOSSIBLE at those common resolutions with 60+ frames in so many of the popular games.So the real problem is you go from "can't do it all" to "still can't do it all" but at least you've got 40 frames going to 55 on your one screen... with maybe one more setting of 7 at ultra...
---
For others with 3x 2560 most of us really don't give a crap if they claim they get 2x frames - because if they don't have 2 or 3 or 4 of them running, they are stuck in turn down the eye candy crapsville TOO.

We almost always hear that we are stuck with console ports, the exact opposite of the real truth in the real problem.
A 570 is NOT ENOUGH, a 7870 is not either, nor is a 7970 for 1900x1200.
IT'S NOT GOOD ENOUGH.

75% was wrong, but so is 70-110% faster.Crysis 2560x1600 at the MAX settings its 20 vx 33, which is just over 60%
Drop down to 1920x1200 at the advantage drops to 50%.
Metro its 60% at max res/settings (36vs22.5)
Drop that down to 1920X1200 and its just over 50%
Dirt 3 its just over 50% at max res/settings Drop that down to 1920x1200 and its remains just above 50% ( 104 vs 68.4)
Battlefield 3 its 50% (49.7 vs 32.6) at max settings/res.
So where the heck are you getting 70% to 110% ??
2 1/2 years ago I payed around 66% of your price, and I'm getting 66% of your performence, ALMOST 3 YEARS. THIS IS NOT MOVING THINGS FORWARD

Get back to us krummer when the 7870 is "released" and has "stable drivers" that "work most of the time" in "most of the games" and the IQ cheats of 10% driver default plus ever more now with this new blur job called MLAA and the lack of LOD bias up high enough that "in the case of SSAA" it's another low detail IQ cut down, not to mention other things like PhysX and tessellation above 10 all the way to 32...the other "unneeded" "eye candy" that "sucks" because amd sucks at doing it.*
9% , minus 10% standardized cheat, minus SSAA LOD bias cheat, minus MLAA blur cheat, minus PhysX, minus 8 other things I won't take time to mention doesn't sound like "faster" to me.
I mean come on, if the arch is so superior, why all the hack and cheats and crappy blurring and lack of features ?
Are the drivers going to be another ongoing nightmare for 47% of all ibm pc implementations ?

@ Kiste: Agreed.The "competition is necessary" meme needs to die in the tech sector because it isn't necessary.
Most of this stuff doesn't expire or die on its own, not before it becomes obsolete anyways and in order for it to become obsolete there needs to be innovation and performance increases.
That's what drives innovation with technology and it certainly exists without competition.

What are you talking about, considering AMD 7850 is faster in most tests than nVidia's 80$ more expensive 570, at the same time consuming 25% less energy.Malih - Monday, March 5, 2012 - link
I think this is the decision of the new management, they decide to price something that performs better to price higher.Probably will drop the price in the future, but it would require a new release from nVidia with agressive pricing. It is rumored nVidia will release new cards near the end of March.

Shitty pricing again, if the pricing was 50 bucks cheaper I would probably consider buying 7870 or 7950 at this moment. These high prices will just have me wait to see what Nvidia has to offer.piroroadkill - Monday, March 5, 2012 - link
Huh, I thought it was GTX 570 class for less.Seems solid enough.

For the 7850, I mean.chizow - Monday, March 5, 2012 - link
This pricing isn't nearly as bad as the 7770 or 7950/7970, but its still pretty poor overall given it once again, slides right in to existing price structures offering very little incentive to upgrade and very little price performance value compared to what has been available for 14+ months.
