    I'm just a bit surprised that this rumor hasn't made it here yet. Here's a link:
    http://www.nvnews.net/vbulletin/showthread.php?t=58776

    ...if you do some googling, it looks like some are saying that this will have increased clock speeds as well, while some say it'll have the same clocks. Looks like Nov. 7 launch is pretty universal for the rumors, though.

    HKPEC says the core to be clocked at ~530MHz, and it will be further refinforeced by samsung -1.1ns GDDR3.

    That would be pretty incredible if true. 1.1ns memory? That's rated for 900MHz (1.8GHz DDR)! Isn't the stock clockspeed for the GeForce 7800 GTX 1.2Ghz? Even though most of the time the memory is shipped at slightly lower clockspeeds, that's still nearly a 50% increase in memory bandwidth.

    And 530MHz core? Also would be impressive.

    7800GTX 512MB 1.1ns memory?!?

    Sorry for the crudity of the translation, but Google is still beta-ing Chinese:

    Now that ain't the clearest, but it sounds DAMNED FAST to me! :shock:

    Yup...about 58.2GB/s bandwidth assuming 256bit. :D

    I'd say the core speed sounds entirely plausible, but the memory does seem a bit fast.

    Considering the 256MB Leadtek Extreme already overclocks to ~ 550, I would say 530 on a 512MB Leadtek Extreme is "conservative".

    If Nvidia does go with a core increase, I expect around 480-500 on the vanilla version and 530-550 on the extreme SKUs from BFG, XFX, Leadtek et al.

    Well, one question I would have, though, if the 1.1ns memory speed was true, is how will availability be?

    I have no doubt that they could get a lot of 530MHz-550Mhz cores, but that memory won't be easy to come by.

    A 'large' order was placed with Samsung by NVIDIA some months back now.

    Does any of this really matter?

    at 500+ mhz with comprable memory speeds and 512mb. People are going to see just how unimpressive the X1800XT really is. This has all been smoke and mirrors with this supposed DX AA+AF superiority and people are about to get that made pretty plain to see.

    I hate having to say so, but... yeah. At 530/800+, ATI's benchmark wins will be very, very limited imo. They'll still have the IQ crown, and games specifically optimized for them will have a very very nice performance boost. But that most likely won't cut it for most people, and more importantly most reviewers.

    This is entirely my own subjective opinion, but something I feel is going to happen is that this is pretty much going to destroy ATI's physics ambitions, at least until DXPhysics if that ever happens. I also feel that it is no coincidence that BFG, the only AIB partly financed directly by NVIDIA, is now going to produce Novodex PPUs. I doubt NVIDIA wants ATI to have a lead here when they basically have nothing to counter it with; don't kid yourself, the G70 isn't anywhere near as capable as the R520 in that category.

    Anyone care to guess how a 530 core and 1.1 ns RAM 512 MB 7800 would perform? Or cost! :shock:

    I love competition!

    Why guess at those clocks, though? :lol:

    All one has to do is take a look at the difference between the 9800 Pro and the 9800 XT or the 5900 Ultra and the 5950 to get an idea of what to expect.

    I wouldn't be so sure clock increases will be that high.

    why use such fast memory if you're not even close to bandwidth limited...

    Considering they've had a quater of a year to speed bin GPUs I wouldn't be surprised.
