The Hexus link is not a repost, but the information is.

Be interesting to see if this is true.
I believe that is roughly ~2K higher than an X1900XTX in 3dmark05.

Can the G70 core support Gddr4? just in case ATI desides to release something with that and a higher core clock.

Again, I find it highly unbelievable that the G71, a refresh part, will be sporting about a 2/3 performance increase over the 7800GTX 512MB. Sorry, this is akin to those rumors of ATI's R520 sporting a 80% increase over nVidia's 7800GTX at the time. A few percent increase at the same clock speeds I can see, but those numbers are just too incredible. There might be some highly specialized operations that the G71 might be 2/3'rd faster in, but it'll hardly boost overall performance up that much. Think the jump between the X1800 and X1900. The X1900 provided a decent performance boost but nothing to be jealous of if you already owned the X1800.

Well if the clock speed and additional pipes for the g71 are even close to right it should beat a g70 by quite a bit. 25% more pipelines from going up to 32 and 20% higher clock would definitely boost speed quite a bit. Wouldn't even need any other tuning to beat it by quite a bit.

the real quesion what will they get good yeilds the chip will be much bigger then r580 im gessing close to 420 million tranistors and clocked even higher. I hate to think this part is another GTX 512 only time will tell.

Yeah, this 700MHz 7900 3DM05 # has been posted here before, but probably linking this page. Promising, if true.

 

[Zebo]

700Mhz? 3000 more 3d points? Sounds like an overclocked 512 to me.

 

[Ronin]

You think the cores have that much headroom? I seriously doubt it, Zebo.

hint:
if it was published almost 4 weeks ago, it's probably a repost.

90nm who knows. My math is a little off - but this 7900 is 20% faster clocked than a 512. If we add 20% to a 512's stock 3D marks of 10000, that's 12000. But that 10000 was tested with a Single core FX-57. That extra 1000 to make 13000 could account for the FX-60 in the 7900's test. I'm sure there is core improvments, but nothing revolutionary here.

 

[akugami]

Too lazy to check, what's the stock speed of the 512MB's anyways?

 

[Pete]

The GTX-512? 550/850MHz core/DDR, IIRC.

 

[Zebo]

I thought it was 580/850

 

[Keysplayr]

550.

 

[akugami]

Hrm, I always thought the 512MB was clocked at 600mhz core. Never paid as much attention to it as I had no intention of ever getting one. So if nVidia gets the G71 out at 700mhz core and maybe 700mhz RAM at a decent price...it should perform very very well. It might provide roughly a 10% real world boost to all games over the 512MB. Nice. But again...I'm going to have to wait for a real product to show up and check the specs. If it doesn't live up to the hype, the X1900 will have more mature drivers out at that time. No way in heck, the 6.2 Cats won't be out at that time.

 

[Pete]

Has anyone tested a GTX-512 with its RAM at X1800XT or X1900XT speeds? I'd like to see that as a rough bandwidth "efficiency" test.
