AMD’s Radeon HD 6670 & Radeon HD 6570: Two’s Company, Sub-$100’s A Crowd
by Ryan Smith on April 19, 2011 12:01 AM ESTCivilization V
Civilization V is the latest incarnation in Firaxis Games’ series of turn-based strategy games. Civ5 gives us an interesting look at things that not even RTSes can match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry and compute shaders for on-the-fly texture decompression.
At 1680 the 6670 can almost – but not quite – hit 30fps. As a turn based game this should be playable, but it definitely won’t be smooth if you’re scrolling around. It is interesting to note though that the 5750 doesn’t have its usual advantage here: it’s only ahead by 6%. Compared to AMD’s other cards this is a good showing for the 6670, but thanks to NVIDIA’s implementation of command lists, they have a significant advantage in this game.
Overall the 6670 enjoys a 12% lead over the 5670 at 1680, and 11% at 1280; and at the same time we see a 20% lead over the 6570, one of the biggest gaps between the two cards that we’ll ever see. Meanwhile the 6570 can’t quite keep up with the 5670, falling behind by 8% at 1280. Indeed even with its massive memory bandwidth advantage, it’s only 11% ahead of the 5570 at this resolution. Ultimately Civ V is bottlenecked by more than just shaders and memory bandwidth, and as a result it’s difficult for the 6570 to break 30fps even at 1280 with medium quality settings.

The HD6670 is a nice upgrade for a 9600GT, both of which are 65W cards.I beleive, based on 240GT performance, that the HD6670 has about 40-50% more performace over the 9600GT.
This card has plenty of performance for games published 4 years ago.

Last page, middle of fourth paragraph:"... the Radeon HD 5770 and GeForce GTS 450 are both regularly on sale for under $100 and are easily 30% faster than the 6770."

Newegg has a sapphire 5750 for $103 ARhttp://www.newegg.com/Product/Product.aspx?Item=N8...
Best part is it can apparently be flashed into a 5770.
A 5770 curbstomps a 6670, by more than 50%.

Finally an actual comparison using an older card. I've been using my 8800 GTS 512 for years and yet to really see a game I could determine for sure was GPU bound (I have an old dual Operaton CPU). Thanks to this article I know I can almost definately see some games with todays mid range cards. Thanks!mosox - Tuesday, April 19, 2011 - link
you don't include the HD video quality benchmark but a load of TWIMTBP games instead.Read Tomshardware for a decent review.

Agreed. These cards are not marketed towards gamers. They will more likely be used for media playback and casual gaming, not running Crysis.SlyNine1 - Wednesday, April 20, 2011 - link
No, I wouldn't buy a 6670 for someone thats just going to use it for media playback. There are much better options for that.casteve - Tuesday, April 19, 2011 - link
"The 5570 was the ultimate HTPC card, but the 6450 has dethroned it. "Except Ganesh is still in hiding.....so, you can't say it definatively.
I was going to say, these aren't gaming cards. Then I wandered over to the March 2011 Steam Hardware survey and found ~29% of users had 1280x1024 or less monitors. Yow.
The other humorous factoid was how the 6670 was the equivalent of the venerable 8800 GT; using 30W less in idle and half the power under load. Sort of a nice data point for progress.
But, the biggest missing piece to this article is the analysis for HTPC. How well do the 65xx/66xx score versus the 55xx/56xx/etc? How well do they implement 24fps?
Finally, Adobe is using gpu acceleration for some Photoshop/Lightroom/etc features. It would be nice (instead of Adobe's vague 'you can use your gpu card to accelerate' premise) to have some benchmarks for these lower tier cards to see what they actually do and whether a bottom end card is all you truly need for these apps.

Agreed.Thing is, these new cards are quite usable for people on a budget - for gaming, or to do some gaming in an HTPC, which the 6450 cannot do. I still play games on my rather old 4670.
The video quality and feature set is what makes the 6000 series better than the 5000 and of course the GeForce cards which have severe HTPC / video output issues.

Can the charts with noise levels please include the noise floor of the room, or of the system without the video card installed (which I'm assuming is around 41dBA in this case)? Also, can the distance of measurement be included? I would love to see measurements taken at two distances - one next to the case and one about 3-5 feet away to get the level at a normal seating distance.
