I'm more interested in the bus width. 256-bit on the HD4670 would be nice, but I doubt it will happen.

So it seems the 4670 is not a re-branded 3870, that's some good news for budget/HTPC builders (apparently has UVD2).

Is ATI becoming a freight train???? Ramming into it's competitors with new cards and low prices?

I love this competition thing. I feel that, as a consumer, I am the winner.

The one thing I like less is that I feel I cannot follow this quick technology progress. It seems to me that my 3850 was a good buy only 3 months ago, with a relatively new architechtur... Now I feel like I own a pussy wagon... But money is not available for computer parts every so often....

chipsets, cpus, memory, gpus, super fast hard drives, blue ray....

U took the words out of my mouth! :D

These are a serious threat to nvidia's only hope of doing well at this point - this targets their vunerable mid-range. Remember how AMD has a tight lipped NDA now ... I wouldnt be surprised if these cards were released without any warning.

i wouldn't its still a 240 shader card from the reports ive seen that means it has less shader power than the 3850 even with a 256bit bus the 9600GS/9600GT should eat these for lunch

That old card can do that :laugh:

And it says 320 shaders...

The chart at Wikipedia shows RV730 to have a 256bit and RV710 to have a 128bit wide memory bus. It's up to you if you want to trust it.

I would take that with a grain of salt. I don't know if that is accurate. I have the feeling that at least the config core is not correct. Ati has moved the TMUs into the SP clusters (as Nvidia did) so I think this time the relation between SP and TMUs is going to be mantained the same as in RV770. That means that for 320 SPs you would have 16 TMU as in RV670, 480 SP = 24 TMU. Same happens with the ROPs. Ati in RV770 is now using the same method as Nvidia, using blocks of 4 ROPs, each with 64 bit output, 4 for a total of 256 bits. So in the chart either the ROP count or the memory interface is wrong.

EDIT: Forget about it. :banghead: They can still put 3 ROPS per block and 6 TMU per cluster, even though I find it easier to mantain their basic structures intact and change the number of clusters. Is what made G92 the better design IMO.

I think RV730 will be with 128 bit memory bus, but it is highly probable the cores count to be above 300.
So the ratio of RV635 and RV670 core count dictates.

We shall see :)

Launching a slew of gpus to hit every consumer budget. ATI has found a winner with the current state of the economy. Solid performance for a solid price. Now I await Nvidia to respond, which we know they will. And in the end, we all win. I love it!

the r700 bus will 512 bit in all from 256 because its gddr5 and x2:toast::respect::rockout:
