Memory Configurations of RV730 and RV710 Come to Light
Admidst the a virtual arms race between the two giants of the discrete graphics industry, information trickles about the memory configurations that the mid-range RV730 (Radeon HD4650 / HD4670) and entry-level RV710 (Radeon HD4450 / HD4470) come in.
NordicHardware reports that two different GDDR3 memory configurations could be seen with RV710. Both configurations operate at 800MHz, but the density varies from 512MB Hynix memory to 1024MB Samsung chips. This points to that the HD4450 and HD4470 models will be separated by GPU clock. RV730 offers a bit more variation with three different clock frequencies and two different densities. One 700MHz 512MB model, and two 900MHz models, of which one sports 512MB Hynix memory and one sports 1024MB Samsung chips. And finally, there is one model with 512MB Hynix memory operating at 1000MHz. It is assumed that the Radeon HD 4650 is the 700MHz cards, while the 4670 model is represented by the three remaining cards.

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....
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.
And it says 320 shaders...
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.
So the ratio of RV635 and RV670 core count dictates.
We shall see :)
