No, it was the newest driver.

Hey W0mbat, you have some inside info on VR-Zone's article, which has a page called DX10 demo's, do you have any idea which ones we can expect, and can you maybe unveil which is better in those DX10 Demo's? R600 or G80? :)

http://rage3d.com/board/showthread.php?t=33890816

good news on the power connectors front as kinc says you can use 2 6 pin pcie connectors if you don't have the 8 pin available and i think we can safely assume kinc knows, if you no what i mean ;)

heres the link

:banana: :banana:

Show those fabulous numbers in DX_10, because anyone has those numbers....

The drivers used in the 8800 were the latest.

If that sucks, then it could very well mean that the R600 could beat the G80 right? Or vice versa. :)

Yes, the scheduler is important. In the G80 it runs at half the shader clock, so there are latencies involved here. The scheduler assigns a thread to a streaming processor. Of course it's more efficient to have the scheduler run at the same clock as stream processors. I'm not sure how big the difference is though. If the scheduler can assigns two thread to one processor then the penalty is rather small. I don't know enough about the G80 architecture to tell you about the latencies involved.

I have no information at all regarding the scheduler of the R600 to tell you how it is compared to the one in the G80. The architectures are so complex and different from each other that from specs alone it's hard to pick the better one. Only benches will tell the truth after both companies have had time to optimize for DX10 (and ATI for DX9).

Dankjewel for the uitleg. (Thanks for the explanation) :)

Much appreciated...I guess we'll just have to wait and see.

Graag gedaan ;) = no problem :D

All those features and converters, but they won't deliver an 8pin pcie powerconnecter with the HD2900 :stick:

:thumbsup:

link doesn't work for me:mad:

R600 buyers said that the 8 pin adapter is NOT included in the Retail box. Where the heck are we gonna find this adaptor?

That work?

yup thanks!:)

no real need for it, 6 pin on all pci-e
connections in single or crossfire is just fine....;)

with the 2 6 pin pcie power connectors can you overclock and do you have to use the amd gpu overclocking tool to overclock them as i can't see the overdrive overclocking facility......thanks

We've already mentioned the scheduler present alongside every cluster of sixteen Stream Processors - As well as this there is also a global scheduler present in G80, which oversees the graphics core as a whole.

I have the MSI, ASUS, and Gigabyte retail kits, they all have the 8-pin adapters in them.

Whats on the other end of the 8 pin adapter, is it 2x molex or 2x 6 pin PCIe?

dynasty but you need the 8 pin to have Overdrive in CCC and to overclock right???

Scroll down, I think Kinc mentions something about the 6 pin. I hope this was the answer you were looking for.

Kinc from my understanding is only using 2x 6-Pin Connectors with his OC's. Only real advantage of the 8-Pin is well ATI says its safer for OCing, but it adds 2 grounds to help with the extra current to the card.
