ATI IS ON A ROLL, having taped out its next generation GPU family called Southern Islands. ATI might call it the HD6xxx series, and it could be out before Nvidia gets its GTX4xx line of GPUs fully fleshed out and to market.
The news is straightforward enough. Southern Islands (SI) taped out recently, and is now moving through TSMC. Although the schedule is very tight, if all goes really well we could see a demo or two at Computex in just over a month. This puts SI slightly behind where Evergreen was a year ago, but not by much.
Southern Islands is said to be a hybrid between the all new Northern Islands (NI) and the current HD5xxx Evergreen family. Those in the loop say that Northern Islands was meant to be on TSMC 32nm before that process was killed. Due to the ever-slipping nature of TSMC's 28nm high-K metal gate node, the SI hybrid GPU was slapped together to be fabbed on TSMC's current 40nm process.
Sources tell SemiAccurate that SI uses some of the NI uncore (unshader?), and wraps that around a mildly updated Evergreen shader. RAM is more of an open question. NI was set to use GDDR5+, but since DRAM makers might not be ready, we may end up with only GDDR5 on SI.
In any case, Nvidia has come out fighting with its GTX470 and GTX480, shipping hundreds, some say thousands, of units since ATI shipped Evergreen last September. If all goes well, and it appears to be doing just that, ATI might have Southern Islands on sale before Nvidia gets all of the GTX4xx variants out the door. The end of 2010 will see Nvidia fighting a new ATI line with a year late part that doesn't work within the promised specs, and can't be manufactured.
By the time Nvidia gets to 28nm next year, or possibly in 'GTX480' quantities this year, it is going to be fighting yet another new generation of ATI parts, Northern Islands. If the rumors are true, and the upcoming Fermi II is on TSMC's 28nm bulk process, and NI comes out on GloFo's 28nm high-K metal gate process, Nvidia won't even be in the game.
At this point, you really have to ask yourself if Nvidia will survive. Its chipset business is gone because it didn't understand Moore's law. Its GPU business is like a floating goldfish circling the drain. Its GPU compute business is wounded. And Tegra is being laughed out the door. Meanwhile, ATI is on a roll.
Aliens Vs. Predator: DirectX 11 Game Performance Analyzed TomsHW
Conclusion kirjutas:
When it comes down to performance, Aliens vs. Predator is happiest in DirectX 11 mode running on a card with ample performance. That means you'll want at least a Radeon HD 5770 for 1920x1080 and at least a Radeon HD 5850 at 2560x1600. If you want to use 4xAA, 1920x1080 is a realistic cap, and a Radeon HD 5850 is the minimum you'll need for that setting.
ZoomThat's not to say that DirectX 9 mode delivers sub-par visuals. In fact, it's almost impossible to see the difference. However, in this particular game, the DirectX 11 code path offers higher frame rates and has a monopoly on AA. Those features are important enough to get the DirectX 11 option a solid recommendation.
With texture memory lowered to the normal setting, lesser cards with 512MB like the Radeon HD 5670 can hit modest frame rates at 1280x1024, and the GeForce 9800 GT can handle 1650x1080.
If you're in possession of something with a little less power, you're going to need to lower other settings in order to get a smooth minimum frame rate. Unfortunately, AA is not an option for folks with powerful DirectX 9- or 10-class graphics cards. Even though your system might have the rendering muscle to spare, cleaning lower resolutions up with some AA isn't an option for anything but a DirectX 11 card.

BitSquid and Fatshark have released their Stone Giant DirectX 11 benchmark application as promised. Weighing in at 395MB, the installer can be snagged here.
BitSquid and Fatshark are excited to announce that the Stone Giant demo, using the upcoming DirectX11 game engine BitSquid Tech, is available for immediate public download.
Key features of the BitSquid Tech (PC version) include:
Highly parallel, data oriented design
Support for all new DX11 GPUs, including the NVIDIA GeForce GTX 400 Series and AMD Radeon 5000 series
Compute Shader 5 based depth of field effects
Dynamic level of detail through displacement map tessellation
Stereoscopic 3D support for NVIDIA 3dVision
“With advanced tessellation scenes, and high levels of geometry, Stone Giant will allow consumers to test the DX11-credentials of their new graphics cards”, said Tobias Persson, Founder and Senior Graphics Architect at BitSquid. “We believe that the great image fidelity seen in Stone Giant, made possible by the advanced features of DirectX 11, is something that we will come to expect in future games.”
“At Fatshark, we have been creating the art content seen in Stone Giant”, said Martin Wahlund, CEO of Fatshark. “It has been amazing to work with a bleeding edge engine, without the usual geometric limitations seen in current games”.
Killerwave, eeeem... mismõttes vana asi? See siis ammu juba väljas? Ise ei teadnud sellest DX11 benchist midagi.
Kusagil Crymodi avarustes jäi silma jupp aega tagasi Umbes kuu tagasi vms, siiski olgu uus või vana, midagi erutavat selles polnud, pigem leidus seal labaseid vigu mida sai natuke ka kommenteeritud crymodis.
Kes siis ses testis keda peksab? rohelised v punased?
No need küll pole ehk päris võrreldavad aga foorumitest lugedes jäänud silma(arvestades reso ja enamvähm ka prose, kuigi tulejõud siiski GPU pihta) siis 5790 tulistab 150-160 keskmiselt High tessellationiga, kui 2x480 saab oma 140-150 kätte vaid ning üksinda jääb kusagile 70-80 kanti, OC 470 kukkus samuti 70 kanti, ilma OC 470 on 60 kanti. Kõigil DOF OFF(see tapab rämedalt perfi, rohkem kui tess...)

Blah videos oli kaarti korraks näha.Pole küll nagu eriline .Ma saan aru kui oleks mingis blockbuster filmis olnud ja mingi kuulsa näitleja käest läbi käinud vms.
Ei tegelikult oleks ka siis mõttetu ju _________________ Müüa 32GB DDR4 mälu
