AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 AM ESTThe Elder Scrolls V: Skyrim
Prior to the launch of our new benchmark suite, we wanted to include The Elder Scrolls V: Skyrim, which is easily the most popular RPG of 2011. However as any Skyrim player can tell you, Skyrim’s performance is CPU-bound to a ridiculous degree. With the release of the 1.4 patch and the high resolution texture pack this has finally been relieved to the point where GPUs once again matter, particularly when we’re working with high resolutions and less than high-end GPUs. As such, we're now including it in our test suite.
At 1920 we seem to be more CPU limited than GPU limited, but at 2560 we do see some greater differentiation between all of our video cards. Here the 7870 can edge out even the GTX 580, and the 7850 beats out even the 6970. What’s interesting to see is where the 1GB cards collapse due to the use of high resolution textures – the GTX 560 Ti collapses after just 1680, and the GTX 570 collapses beyond 1920. Going forward we expect more games to be like Skyrim, which will make additional VRAM all the more important.

So, how many people do you know who would spend a few hundred bucks for a performance "sidegrade" that saves them a few bucks per year on their energy bill?Price/performance is still the relevant metric for most people, with everything else being secondary. Not unimportant, but secondary. Noise can also be addressed on cards with high power draw by buying a card with a custom cooler or using a 3rd party cooler.

Some people are just entering the market, some people are coming from 3+ generations ago, some people are looking for HTPC's that can game and need low power and low temp cards that provide solid performance. It isn't a sidegrade for someone who is coming from integrated graphics or maybe a 7800GT etc. It is easy to think that everyone who buys these types of GPU's are knowledgeable and already have high performing GPU's. But that just isn't the case a lot of the time. If you have a high end 5xxx or a mid-high range 6xxx GPU already then there is no reason to upgrade, frankly with the 68xx series AMD isn't looking to grab that market.Kiste - Monday, March 5, 2012 - link
If you're looking for great price/performance, there are plenty of cards that offer more bang for your bucks.If you're looking for raw performance, you look elsewhere, too.
Though I'll happily concede that the 7850/7870 are great absolutely fabulous for everyone who is building a "HTPC that can game".

And exactly where do you look for raw performance, pretty please? Maybe at nVidia 570, that costs 80$, consumes more energy yet is outperformed in most tests by 7850?Kiste - Monday, March 5, 2012 - link
Where would you look for raw performance? How about the 79xx line?And what the hell are you talking about anyway? The 7850 does not "outperform" the 570 in most tests, unless you're again back at comparing an overclocked card to a non-overclocked card. Most 570 cards can do a 15-20% OC easily, btw.
Hell, I bought my GTX570 about 12 months ago for €289. And I'm supposed to be blown away by something like the 7870 in 2012?
The GTX570 became available about 14 months ago. It took AMD 14 frigging month to come up with a card like the 7870 that is 9% faster on average at the same price point?
Gee, what a marvel of technology.

570 is 250% larger and 9% slowerIts a giant leap
talk about marvel of technology
Your card is tech from stone age compared to a 7870.
Old tech is old

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.Yea we are sure moving forward...

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.RaistlinZ - Monday, March 5, 2012 - link
This is true. I came from a 5870 to a 7970 and at 2560x1600 the 7970 is easily twice as fast.And that's even before overclocking. My 5870 could barely overclock for crap, whereas my 7970 overclocks 27% on core and 18% on memory.

Not according to Anandtechs benchmarks.
