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.

It is not the dumbest statement ever. Have you looked at multiple sites benchmarks ? Clearly a 2 GB 6950 Power Color flashed to a 6970 or a 6970 is worth keeping. Hardly an improvement over those situations for the price you would be paying for a 7870 and 7850.ExarKun333 - Monday, March 5, 2012 - link
Then you don't follow the graphic card industry very well at all.MadAd - Monday, March 5, 2012 - link
did i just read a different review? looking at this i did - Im on the 6950 and no theres not enough performance difference.also, comparing apples to oranges and saying theres a gain isnt going to work - if someones going to OC a 7*** then im sure they have also OC their 6***, so comparing a straight 6*** to the 7*** OC results and calling it a difference is smoke and mirrors.

You guys dont get it. Why are you comparing the 7870 to a 6950? Should be the 6870 but even then The 7870 smashes the 6950 when overclocked. the 7870 performs like a stock 7970 when overclocked. You cant compare overclocking on the 6 series to the 7 series. The 7 series is the sandy bridge of GPUs.Why compare last gens high end to this gens mid range? If you have a 6950/6970 you should be looking at a 7950/7970. A 7950/7970 will give you 70% increase in performance when overclocked. AMD left heaps of overclocking headroom for easy overclocking.
Sure, the price is a little high now, but just wait a few weeks until Nvidia cards arrive and prices will come down. New tech is always a little expensive when it first comes out but no one is forcing you to buy now. Just wait a couple of weeks

"Why compare last gens high end to this gens mid range?"Because were introduced at the same price point. Video card names/numbers are completely arbitrary, you have to compare cards at a given price point.

So I have one the the early 6950 2GB cards unlocked to 1536 shaders, and a 935/1275 overclock.Running at 1920x1200 in skyrim with the high resolution texture packs from Bethesda starts to lag.
Yes I'm being petty, but as a PC gaming smoe, I'm looking for a card that's under $300 that will dominate what I have.
I can't find a confident vote for a strong successor in the sub $300 range to replace my current card.
This makes me sad. Also with all the growing pains 69xx series had - and AMD's dumping of VLIW4 makes me pretty sure 69xx is a dead end for any future driver improvements.
Maybe I can sell my 6950 for $100 to subsidize a 79xx or a Kepler?

I'll take it.mpschan - Monday, March 5, 2012 - link
I'd tend to agree with your assessment. Only those looking for bleeding edge performance should consider the upgrade to the 7900 series.The price/performance curve is a little disappointing, but not unexpected. This is what happens when you:
a) Move to a new process
b) Implement a new architecture
c) (Most importantly) Have no competition
They need to make their money back on the first two, and having no competition allows them to do that and then some.
But look at the thermals and power draw. Decreased power usage with a small gain in performance? Where have I seen that before ... oh I know, Intel!
Welcome to tick-tock folks. They took their process shrink and used it to allow them to draw less power, not tear up the performance charts.
This means the next generation on 28nm has room to expand. 1280 SP for the 7870 can be 1600 for the 8870. A 212mm2 die can be 300mm2. 190w can be 220w.
Ultimately the performance of these cards will come down to power drawn. The huge jumps in performance that we used to see existed because of drastically improving fabrication technologies combined with better ways of rendering screens. I think those days will be few and far between now.

You have a point, this generation is not worth spending the $$$ to "sidegrade". I don't kepler doing anything to change that other than forcing AMD to have decent prices.cactusdog - Monday, March 5, 2012 - link
How is a 7950/7970 a "sidegrade"?? To a 6950/6970? Its a massive performance increase. If you have a highend 6 series GPU you should be looking at highend 7 series. Not midrange.
