AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 AM ESTCrysis: Warhead
Kicking things off as always is Crysis: Warhead. It’s no longer the toughest game in our benchmark suite, but it’s still a technically complex game that has proven to be a very consistent benchmark. Thus even four years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and the answer continues to be “no.” While we’re closer than ever, full Enthusiast settings at a 60fps is still beyond the grasp of a single-GPU card.
As we’ll see throughout today’s benchmarks, Crysis ends up being a good proxy for the 7800 series’ performance, especially compared to the outgoing 6900 series. Ahead of the Southern Islands launch there was some doubt that AMD could deliver 6900 series performance with the 7800 series, and this doubt increased after the 7700 series underperformed the 6800 series. Results like what we're seeing with Crysis should make it clear that the 7800 series is more than a competitor for the 6900 series, with both the 7870 and 7850 equaling or beating the 6970 and 6950 respectively in almost all tests.
Overall at 1920x1200 the 7870 gets 39.9fps, which isn’t quite enough to smoothly handle enthusiast quality and 4x MSAA. Meanwhile the 7850 is farther down the line at 35.4fps; both cards would need Crysis’s settings turned down to reach 60fps here. Compared to the 7950 the 7870 trails it by 17%, giving AMD’s next card up a fairly wide lead in this game.
Meanwhile compared to NVIDIA’s lineup the 7800 series does quite well here, reflecting the fact that the 7800 series doesn’t have a true equal in NVIDIA’s existing lineup. At 1920 the 7870 leads the GTX 570 by 12% and is within spitting distance of the GTX 580, while the 7850 is virtually tied with the more expensive GTX 570 while it leads the GTX 560 Ti by 19%. Elsewhere at 2560 the 7870 has a similar lead, while the 7850 has a 41% lead on the GTX 560 Ti; while 2560 is not the ideal resolution for either card, it’s something to keep in mind when we begin discussing the impacts of the 7800’s 2GB of RAM.
When it comes to minimum framerates in Crysis the relative rankings are nearly identical. The 7800 series extends their lead over the 6900 series by a slight degree, while the lead over NVIDIA’s cards shrinks slightly.

I have absolutely no problem with that.The apt comparison would be the 7900 series though, and those only really fail on price.
Which will likely change if Nvidia brings something competitive to the high end with Kepler.
Lets face it, until the current consoles die in a fire and/or display makers see fit to bring sensibly priced >1080p panels to the desktop there's really no need for more performance in the desktop space.

The fact the things are sitting still.I'm running a 5870 which is basically 75% the performance of a 7970, and I paid 379 for the 5870. Which is also 75% of the cost of a 7970. The price of a 7970 is basically the exact same price structure as the 2 1/2 year old 5870, So we are stuck where we were in 2009, yay.
This is NOT how the computer world is supposed to work, and as big geek, I don't like it.

75% performance of 7970 would mean that it's 33% faster than a 5870. And that's just not accurate. I have a 5870 as well, so I was paying a lot of attention on how much faster the 7970 is in various reviews. Everything I've read indicates that it's anywhere from 70-110% faster at 2560x1600 resolution (I run 3600x1920, so likely even even more of a difference). That's not even even considering the massive overclocking headroom of the 7970 vs barely any OC headroom of the 5870. Overclocked, a 7970 is easily twice as fast as a 5870.Alpert - Tuesday, March 6, 2012 - link
The 6950 retailed for $299 and the 6970 retailed for $369 when they were released. 10-25% performance increase for every new series of cards is what to expect. Now we can clearly see these card perform better then the 6950/6970, hell a 7850 overclocks to what a GTX580 is capable of.The value of what was a $600 GTX580 card more then a year ago, The value of a $499 GTX580 today, you get a $300 7850.
The price you pay for performance is always going down just not in big steps.

These should be excellent cards for crossfire solutions, especially when combined with the new PCI 3.0 bus system. They represent significant improvements in heat, power, and noise at their performance levels. I think these would work well in small form factor gaming PCs, especially when combined with the upcoming Ivy Bridge CPUs, which max out at 77 watts. I don't want a loud, space heater that sucks down massive power for a computer. I have also noticed that cooler systems tend to last longer and have few problems. I feel confident that the prices will come down once the competition from Nvidia comes out next month.I am thinking that we are approaching a really nice time to upgrade if you like balanced systems that deliver excellent gaming performance in reasonable portable packages that wont disturb your personal environment with excess heat and noise. I intend on waiting for Ivy bridge and Kepler before pulling the trigger, but I am eagerly awaiting upgrading evertyhing.

The price point on the 7xxx series cards seems to be a little too high at the moment, the only advantage they have is that that do outperform the GTX 5xx series cards in a number of ways (power consumption, performance, temps). The biggest problem with the 7xxx series is that they just don't perform that much higher at each price point than AMD's current 6xxx series cards. Why get a 7770 when you can, for the same money and MUCH more performance, get a 6870? The prices will drop when Kepler rolls around I'm sure, but for now, a little too high, given that most of the increases at each price point don't come in the realm of performance.CeriseCogburn - Thursday, March 8, 2012 - link
AMD has been listening to their little screaming fans who wailed that electric usage and core temps are all the rage....So now the amd fans need to PAY UP SOME $$$ for the nice electric consumption and core temp reduction... let's face it - they have told us all for years now those two things alone are well worth a purchase decision, PERIOD.
I guess it's time for them to dig down deep since their Master has responded with everything they declared of utmost importance.
What's wrong AMD fans ?

I would love to see Anandtech start to look into the stutter/inconsistent frame problems with these modern graphics card reviews. The techreport has been doing a good job in blowing the lid on the problem, but you guys should be able to start to apply pressure to AMD/NVidia to improve the situation. The minimum average is not the worst it can be, the worst frame time is what you need to worry about. Averages over a second just aren't accurate enough.loeakaodas - Monday, March 5, 2012 - link
These look like great performing cards that need a $50~$100 price drop & hopefully nVidia's new offering will force AMD to compete like they did with the legendary 4800 & 5800 series. I was hoping for a sensible upgrade path from my 2x5850's but it doesn't look like that exists yet, at least not at these price points. I'm better off of putting that money towards a large SSD upgrade, otherwise this midrange 2.5 year old system doesn't really beg for an upgrade.ET - Monday, March 5, 2012 - link
The OC 7850 beats everything hands down at the 2560x1600 resolution, which doesn't look right considering the rest of the benchmarks.Also, on the Skyrim benchmark page the writeup has "GPUs GPUs" on it.
