According to the post at Tomshardware.com rumors about RV670 being a Radeon HD 3000 series is correct. Tomshardware even posted a picture and other various web sites reported specifications about the upcoming Radeon HD 3850 and HD 3870 cards, based on RV670Pro and RV670XT GPU's.

According to the info RV670, or HD 3850 will end up clocked at 700MHz for the GPU and 1800MHz for memory. It will support DirectX 10.1 and PCI Express 2.0. High performance HD 3870 based on the RV670XT will end up clocked at 825MHz for the GPU and 2400MHz for the memory. According to the picture, HD 3870 will need a dual slot cooling solution. Same as the HD 3850, it supports DirectX 10.1 and PCI-Express 2.0. Both GPU's are made in 55nm manufacturing process and comes with UVD.

These are the long rumored additions to the ATI line to go up against Nvidia's best.

its still doesn't tell whether its memory controller is plain 256bit or 256bit ring bus memory...

It's 256bit external.

There's already a thread on this: http://forum.lowyat.net/topic/537956

oh my gawd does that mean my PCIE 1.0 is useless dy if i want this

can the pcie2.0 gpu use on pcie1??
those who plan to upgrade i think need to reconsider again to shift to pcie2 rather than stick to pcie1...

Aiks ... Another high end item . Me 8800 & 2900 also havent use

wah.... maybe will grab the PCIE1 when the 2.0 is out... lol... I'm alwayz one season behind ..... cos budget man,,, budget...

You are a smart consumer!!! haha

I think PCIe 2.0 can use PCIe 1.0 cards, but not the other way round... it's good to see more goodies coming up from ATI, this will give Nvidia some good run for the money

so many thread bout this hd3800, mod i think u need to do something bout this...

hmm, i'm definitely gonna jump onto the PCI-E 2.0 bandwagon, but i'd wanna wait for Nvidia's cards first cus they look slightly more promising, i guess.

here we r!bek 2 the AGP scenario again!dammit!

If I'm not mistaken, you can use PCI-E 2.0 card on PCI-E 1.1 and PCI-E 1a motherboard, the other way round is of course can PCI-E 2.0 motherboard support PCI-E 1.0 card. No point nVIDIA and ATI come out with a card that use newest technology that only few people got! (*NOTE: PCI-E 2.0 motherboard only available not too long ago... ) But 1 thing for sure is, if above cases hapened, both will run only at PCI-E 1.0 speed la, like last time AGP 8.0 but at AGP 4.0 speed.

PCIE ver 2 offers more bandwidth that's all, I wonder will the game take full advantage of that?

The incoming RV670 is a trim down version of R600. Just done the spec comparison. I doubt it can win against the incoming 8800GT.

R600 spec:
http://ati.amd.com/products/Radeonhd2900/specs.html
The specs between these GPUs are nearly identical to each other...
except some minor changes.

BTW, there is a 8800GT performance review (chinese website):
http://topic.expreview.com/2007-10-23/1193114539d6255.html

8800GT is v.aggressive too.

but if the ati new chip benchmark is not as expected..they blame driver issue..

True but at least they work out somthing for us by offer newer driver which improve gaming peformance.

Please don't forget this is a mainstream card not high end. Glad they keep the best out of R600 and remove the unnecessary such as 512bit memory bus. Not to forget UVD is present here this time around. If this card can hit the sweet spot price, its pretty good card imho. And it should since this card is a mainstream card.

can wait to see both card on the performance against nvidia

Yeah, that's why some people actually bought the 7900s.
In time when the driver's done, you'll be scared s***less.

yes I did read somewhere that ati is fixing the driver , n when it done, the gc will be really kickin its rival's a*s..
thats why we see ppl still buying the gc although the issue came up
