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.

Metro 2033 (the highest settings bench)Radeon 7950 33fps
Radeon 6970 27.5fps
Radeon 6870 32fps (the second highest bench)
Weee!!! $400+ for 5.5fps more.
Not sure about you, but to me, spending that kind of cash for an imperceptible increase in performance is having no sense of money's worth.
This generation of cards can safely be skipped until the 8xxx/7xx series from both AMD and NVIDIA.

Picking up one specific benchmark to underline your point. Great reasoning skills, you should join a debate team! Also, that 5.5fps is still 20%, with the good track record of overclockability, it can reach as much as 40%. But you stick to your point.arjuna1 - Tuesday, March 6, 2012 - link
What? were you expecting me to post a powerpoint presentation for just for you??The numbers are there, look at them if you want, but hey, be stuck in your point, only a frustrated basement geek can think in way to justify spending $400 +/- for less than 50% increase in performance.
Be careful of not falling of that horse, seems pretty high.

Please check the avg frame rate improvements, not some specific results. But everyone agrees that 7xxx cards are a bit overpriced and that's because they don't have competition right now. If you worry about power consumption, buy these cards now. Or more interested in price/performance, wait till Kepler is released.arjuna1 - Tuesday, March 6, 2012 - link
I can agree with that, after Kepler is release prices will go down and maybe then the 7xxx series will increase in the perceived value.CeriseCogburn - Thursday, March 8, 2012 - link
If there's no competition then they aren't overpriced because they cannot be touched by anything, hence making their price absolutely correct !!!I call that "reality".
If Kepler blows their doors off, their price will fall. That's reality too.
It's time for all the amd is cheaper crud to go the way of the dinosaur.
Recently a 460 was an unbeatable value. Then a 560ti was as unbeatable value. Currently a 6870 is an unbeatable value.
These things happen, and a deal is not the general aspect of the video card prices, which generally speaking wind up right where they should be.
The deal is the exception to the usual rule across the board, and "the deal" as in "big price drop" is usually just one card here or there for a short period of time.

Radeon cards have been coming out at $700 and $600 and $500+ for a long time man - even with competition.I don't know what planet you people come from when the constant repetition of "it sounds good" becomes an absolute meme and ongoing restated theme but in no way reflects even a tiny kernel of truth as far as reality goes.

Yes dagamer34, Ryan praises amd for drying up their 6000 series channel with such precision. Then we get this praise - the perfect price structure by AMD, and "it's conservative pricing" according to the author even though it's $40 and $30 higher than it's Nvidia counterpart..." With AMD targeting the ~$320 570 and ~$210 560 Ti and given their conservative pricing on the rest of Southern Islands, it should come as no surprise that the 7800 series is priced equally conservatively. The 7870 will have an MSRP of $350, while the 7850 will have an MSRP of $250. With the 7800 series completing the launch of Southern Islands, this gives AMD a consistent price structure for the entire family: $550, $450, $350, $250, $159, and $109."

I see. So more expensive is conservative, and the 6 AMD price figures are perfect and consistent...
I am so sick of it...

Thus far, AMD's first foray into 28nm graphics has been unimpressive. From a price/performance standpoint, the 7000 series has not given the usual incentives for upgrading that is regularly associated with the move to a new node. I hope a strong competitor from nVidia is on the way, as that would bode well for consumers such as ourselves. As it stands, the 7000 series lacks value except at the very high end, where price/performance is of little concern.Kaboose - Monday, March 5, 2012 - link
Price vs. performance is not the only factor, some people are concerned with power draw as well. Others are interested in temps, and noise. The price could use some work (come on Nvidia) but besides that the 7xxx series has been fairly impressive in regards to overclocking, power, temp, and noise.
