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

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....

[GLENBOY]

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

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).

From http://www.elitebastards.com/cms/ind...1&limitstart=2 :

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.

Good news for some worried folks here

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.

[deathman20]

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.

Borrowed these two images from here. Same settings under the single frame 3dmark06 rendering options. Jpeg compression makes them more than a bit limited, but thought I'd put them up anyway. NV drivers 158.16

Both: 3DMark06 1280x1024 8xAA 16xAF

2900XT left. 8800GTX right.

[deathman20]

Well both cards have there positives in that test. I see vary little difference between them just taking a glance at it.

[insurgent]

i think the ones on the right have more prominent jaggies

[Ubermann]

I see no difference, only the light

Yes for OD in CCC, But like I said b4 2 x 6 pin pci-e connections per card will do just fine.
I been using this since day 1 and have not had any conflicts or issues
to mention.

I think the most guys will have a 2 x 6-pin connectors coming from their PSU, so the ideal adapter would be something that takes a single 6-pin and a molex to make an 8-pin... is that the case?

Thanks,

Suman

[theteamaqua]

so if 2x6 runs jsut fine even when oced .. why would they include the 8p .,...

yeah and for the adapter i dont want 2x6p .. its just a big waste and stupid .. cuz if ur PSU dont have 8pin u will need a 3x6pin jsut 1to power 1 2900Xt ...

so molex+6p or 2xmolex > 8pin wil certainly be nice

fornowagain, pictures you posted have different jpeg file size

radeon pictures are 3 times smaller

until we don't see bmp source it means nothing

This is completely bogus. If you flip them back and forth, you will see the ATI pictures were slaughtered with heavy JPEG compression. Check the file sizes - the Nvidia pictures are much larger. Someone obviously has an agenda, and I hope no one goes and takes that "comparision" seriously.

Yup, see above post. Someone's busted.
