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.

I agree it's kind of disappointing. Even a 5750 was a good improvement over a 3870, and here there's nothing approaching this kind of performance benefit over the 5870 from these. Though I think part of it is that the 5870 still holds up well in many games, as these benchmarks show.Kjella - Monday, March 5, 2012 - link
I don't think it's that terrible... the 7870 fits pretty much the exact same power envelope as the 5850 and is starting to be a pretty solid performance upgrade. Yes it's a $350 card but inflation adjusted the $279 (pre-hike) 5850 is nearing $300 in 2012 dollars. A good deal and a good cooler (the reference cooler on the 5850 works, but is hardly quiet) and they may get a sale. Just waiting for Ivy Bridge, if nVidia hasn't shown a stunning Kepler by then I think the 7870 is it.Death666Angel - Tuesday, March 6, 2012 - link
Average increase of 40% in performance and you are comparing a high-end graphics card to a mid-range graphics card.DominionSeraph - Monday, March 5, 2012 - link
So, AMD discontinued the $250 6950 and $350 6970 to give us... a $250 6950 and $350 6970.Not exactly impressed.
Looks like it will be up to Nvidia to save us, just as they saved us from the price-gouged 5000 series with aggressive release price of the GTX 460 with price drops on the GTX 470. (That one action set the pricing scheme throughout the 6000/500 series)

I'm not upgrading this cycle but I do wish to see Kepler out sooner to drive down prices. This is business and AMD has a few months of no competition so they are going to do all they can to reap massive profits.Nvidia isn't going to save you, they would do the same thing if they were in AMD's position. Remember nearly 5 years back with the 8800GTX going for 500+ for over a year? Yea......

A halo product with no competition is beside the point. We're talking about the 7800 series which sits right in a range where there are competing products, and AMD is pricing it to suck you dry.The fact is that the 7000 series is not undercutting the 500 series the way Nvidia undercut the 5000 series. A $250 7850 vs a $270 + free Batman Arkham City GTX 560 Ti 448 Cores is about equal price/performance (maybe a tad in the favor of Nvidia). Contrast this to the GTX 460 being released at $200 when the 5770 was $180. The GTX 460 blew the doors off the 5770 and instantly said the appropriate price for that card is ~$130. A few months later we were seeing $110 5770's and $150 GTX 460's, and that's where we've been at ever since.
AMD refuses to aggressively compete with Nvidia. They simply slot their products into Nvidia's pricing structure. So prices only change when Nvidia drops theirs and AMD is forced to follow. This means that we, the consumers, are dependent on Nvidia to save us, because AMD sure as hell won't.

Not really a valid point of comparison though.Looking through several reviews of the 7800-series the 7850 lies closer to a 570 than a 560 Ti most of the time, while offering more and better in every possible category.
Sure, the 7850 isn't on the market yet but assuming the ~250 USD pricing holds true I couldn't possibly recommend a 560 Ti, or even 448 core version, over the 7850 with a straight face.
It could still be cheaper, sure, but it's nowhere near the pricing disaster the 7900 and 7700 series are.
To my mind the 7800 series were the ones to wait for.
Granted, with a 6950 myself I won't be upgrading until the 8k-series at the earliest. Unless Kepler turns out truly amazing, and brings triple display functionality on a single card.

If I recall Nvidia hasn't really under-priced AMD in recent memory, they've always tried x more performance sold for >x price.ET - Monday, March 5, 2012 - link
"AMD discontinued the $250 6950 and $350 6970 to give us... a $250 6950 and $350 6970."When you put it this way, it's quite a likeable upgrade actually. Slight boost in performance, lower power and better thermals, upgraded features, all for the same price. What's not to like?

What's not to like is it took them 16 months to put out a greener refresh sidegrade.
