I've been seeing this on a few sites and was wondering what some of you guys thought of it.
And from www.warp2search.com
Just pretty promising to me, but I'm sure Nvidia has something up their sleeve to match this offering from our friends over at ATI.

A FEW DAYS BACK we talked about what we knew about R300 and now it seems our Chinese friends have a few more details to show the world.
The site agrees with us that R300 is intended to compete with the next Nvidia part, NV30, but have added some interesting notes about the spec of the card.
The site reckons the card will be produced using 0.15 micron technology which is realistic since you cannot get volumes of 0.13 micron process quite yet, but as soon as TSMC and UMC get going on this process, the R300 will shift to this for faster chipolatos.
PC Pop claims that the frequency will be 350MHz and as I previously reported, R250 will have the same frequency so this looks quite realistic with R300 technology as well.
With 0.13 technology, ATI will be able to have 400MHz chips but I would guess that this will be kept for its annual spring refresh.
As I said there will be eight rendering pipelines and it is still unclear how many texture units chip will support -- two or four. The memory should run at 800MHz and for this you will need 2.5 nanosecond memory, which is not yet available.
The 2.6ns memory should be available in less than a month, so 2.5ns should be available in the next quarter or so, when this card starts to become more reality than chimera.
The chip will be able to address 256 MB of memory.
As for DirectX support, the PC Poppers said as we did that the card will have support for DirectX 9 but not clarifying whether it supports DX 9.0 or 9.1.
The site claimes the chip will have two Truform units but this does not make any sense to me. Truform should not be relevant in most future games. As for memory optimisation ATI will have improved HyperZ 3 and they claim 12.6 GB/s bandwidth.
The chip is not taped out yet but it should be pretty soon now and introduced this summer.

Just pretty promising to me, but I'm sure Nvidia has something up their sleeve to match this offering from our friends over at ATI.
I hope it's coming out, I'll buy one, I can't wait!
