    http://www.overclockers.co.uk/acatalog/7900_Series.html

    Due to be released today @ 2pm.

    Some seriously quick cards there!!!!:eek: :eek: I see that the 1900 ATI series cards are already down in price after only 2 weeks!!! Interesting to see some true benchmarks on the cards. By all accounts the 1900 ATI card is a belter!!

    Nice 700/1800 clock speeds on the 7900 GTX!!!!

    Will stick with my 7800GT for now!!

    Looking forward to seeing all these new cards being compared. Ive been holding off waiting for the 7900.

    I also heard that the 7900 will be dual core! (two gpus on one board) making quad core possible with a regular SLI mobo.

    However, they did say that at the moment, the CPU is the bottleneck so anything above a 7800GTX SLI wont give any better results.

    Lets hope that devs can work out how to use those dual and quad core CPUs to give us more performance.

    At the moment we are pretty limited to over clocking an FX 60 to get better results....

    Agreed

    CPU limitation, Nvidia have already said don't expect much from QuadSLI at these standard low resolutions.

    Try 2056x1648x4AAx8XAF on a 30" Dell with an overlcocked FX60- then have a comparison.

    When a single GTX is basically CPU limited at those settings then Quad SLI obviously wont be great.

    Can see some results here

    The worrying thing is the power draw these will take - 120w per card, say if you overclock it thats around 145w = 12amps per card so 24amps for the cards!

    Not impressed in the lightest.

    x1900xtx looks far more an attractive proposition and also has HDR + AA.


    Suprising considering the lead NV had when it forst released the 7800GTX. The only plus point is the power/cost ratio of the 7900GT. Now that is good, altho some of the clocks the GT has and there are no ram sinks or any kind of cooling on the memory!

    I'm hoping the 7800GTX 512 drops in price and that's the card(s) to have.....

    yeah - not impressed with these results. So the new card 7900 is potentially slower than the 7800 in sli?

    Are these results being skewed by the volt modding that the guy has done on his card?

    Yeah that 7800 is souped up big time.

    From other results I've seen I've not been overly impressed. If I were to choose a single top end card now, it wouldn't be an NV one.


    Find this quote interesting : '7800GTX and 7900GTX are the same card, and the only difference is that the 7900GTX has a 90nm GPU.'

    If that's the case then I'd defo buy a 7800 512 over the 7900GTX if it drops in price....

    agree - i can't see how they can keep the 7800GTX 512 at such a high price and be able to justify it against the "new" 7900GTX.

    For the mid to high end (meaning not HIGH end) games user a single 7800gt (now as little as £185 including VAT) new is still plenty to run a 19" tft and gaming on. (at present!!)

    Upgrading the gfx to a 1900 or 7900 etc will mean spending £200- £400 on a new processor also to be able to benefit from the faster gfx card.:eek:

    Personnaly, now I've seen a few figures, if the 7800512 doesn't drop in price I'm going x1900 xfire....

    More features, faster and same if not cheaper price point.

    Availability could be the main factor here.
    As far as I know the 7800GTX 512 is very hard to get, while a 7900GTX 512 might be a lot easyer to get as long as they actually produce them.

    Price might also be lower than the X1900 so that might be another reason.

    Still, you are all right in saying that the new card isnt all that impressive.

    Looks like it might be worth waiting for the next Nvidia GPU (NV80?)
    Personaly I plan on geting that dell 30" that does 2560X1600 so i will be needing the 7900GTX. Might wait for the 1gb models though. Also want to see the dual core ones.

    I was waiting for this card but I don't think I'm too fussed after reading that, I'll probably get a 7800GTX now rather than wait anymore for the n80xx or whatever they call it!

    btw is there much difference performance wise between the 256/512 GTX?

    At higher resolutions yeah because of the higher clock speeds on the 512...

    The 512 is the sweet card for nv if it drops in price....followed by the 7900GT.

    The x1900xt is the faster single card, more features and cheaper. It's a no brainer really.

    i'll stick with my 7800, I see no reason to upgrade expect for the blag factor of saying "I've got a 7900". When mine starts failing to play new games without making them look like doom1 i'll consider something new

    For the price similarity and the HDR + AA on the x1900 series, there is still only one winner in my eyes. Then there is the rumoured price drop in the x1900 series, if that does indeed happen then it cements the decision.

    The thing is there were rumours this was gonna stomp, and I mean STOMP on the x1900, but it so so hasn't. For a company that was miles ahead with the 7800GTX at the time of launch, they seem to have gotten a bit lazy releasing a minor speed bump refresh. Smacks of ATi refreshing the old 9700Pro to the x850.....

    In NV's defense the next line of cards from both manufacturers will most likely not be refreshes due to DX10.....

    I think alot of ppl will skip this round and wait that out.

    there has already been a small price drop even 2/3 weeks after the launch of the 1900 series - cheapest card on overclockers has come down from £350 to £310 already.

    You will find that the x800 line is nothing more than a 9700pro on steroids, design wise. Just added pipes and higher clock speeds. ATi knew they had a good thing and were spanking NV big time, so I guess they got lazy and just kept releasing the same card but faster and faster. Not sure technically but I'd say the x1800 is similar too. But don't quote me.

    They got spiked big time by the 7800 series, so had to redeisgn and came up with the x1900.....

    Very basic analogy and not very technical, but from how I understand it that has been the chain of events.

    So when I say the 7900 smacks of ATi's lazy refreshes.......

    Its as though this card is just a stop gap for the NV80 (which should hopefully be impressive).

    Both companies cards will be I'd say. Both DX 10, both (hopefully) in the 32 pipe range and both 1Gb memory size. Monsters basically.

    With the 7900 range, I've read alot and have basically come to the conclusion that the GT is (depending on which brand you buy) either a smaller 7800GTX or a (again depending on brand) slightly overclocked GTX. highest I've seen is the XFX XXX version at 560/1650, which when compared to a stock GTX 420/1200 is a nice little speed bump but not worth it in my book for current GTX owners......


    The 7900GTX seems IMO pointless. There is literally no difference between it and the 512GTX from the reviews I've seen and can only guess that NV artificially held the 512GTX back in numbers in anticipation of the 7900GTX. For current 512 GTX owners there is no point whatsoever in upgrading.

    All I can say is if u have a 6600/6800 then the 7900GT is a wicked upgrade.

    For 7800 owners...leave it.

    For x1900 owners laugh and say, no ta.

    i see what you meant now, i just coldnt work out the smack bit, not a phrase ive heard of before lol.
    i dont think the 7800 series really outdid the x1800 series, it was just they had a massive headstart. the x1800 series perform better then the 7800 series do.
    ie, x1800xl vs 7800gt and the gtx vs the xt.
    the 512 gtx did have a bit more to offer though.

    tigerblade, do you know whether the x1800xl's can do AA/AF and HDR at the same time? which is best out of a x1800xl and a 7800gt would you reckon?

    Yes the x1800 can do HDR + AA.

    I'd say go for the x1800XT over the 7800gt, especially when the x1800XT costs £235!!.....thats insane, when compared to the £210(ish) of the 7800GT. When the x1800XT is on par with a 7800GTX, plus the HDR + AA, it's an obvious choice. Even the x1800XL over the 7800GT if you couldn't stretch.

    EDIT - the 7800/7900 series can do AF + HDR, it's just AA + HDR it can't do.

    cool cheers.
    well im getting rid of my 7800 in favour of a xl, purely for bf2 really as it looks so much better on a ATi card. its not costing me much at all either :thumbsup:
    i would plump for the x1800xt but ive read that card is a bit overkill for 19inch tft native res's so ive given it a miss.

    Remember the one big difference between the two is noise, if your after building a quiet pc from stock parts than a 7800/7900 has good performance while being near silent, the 1800/1900 on the other hand are not. The 1900XT is the fastest of the cards arround but i'm happy with my 7800GTX and don't need a dyson inside my pc.

    For less than £20 a third party fan/cooler should be availible negating the noise difference though.

    Lets hope the next set of cards provide a decent spead increase, as the current 'new' ones are like 9700pro to 9800pro, a difference but if you have the former your not likly to notice a differnce by moving to the latter.

    to be fair this x1800xt is less noisy than the 7800gt i had before, i cant comment on the noise from the 7900 series as ive not been next to one. even whilst gaming this card is less noisy.
    also, i have read that there isnt any aftermarket coolers released yet that can cope well with the x1900xtx's. ive read on a few forums where cards have broken with heat issues when using the likes of the zalman vf700. hopefully the new vf900 will be more up to it.
    the stock x1900xt cooler is the best cooler for that card atm, if its noisy or not i have no idea.

    The whole noise argument is trivial imo, when you can get slap an nv silencer/accelero on a card and make it near enough silent WITH better cooling.

    The accelero looks good for the x1900 series. Cools better than ref fan and is very quiet The line doesn't have the DHES that the silencer range has, so the heat stays in the case. I suppose with good airflow this wouldn't be a problem.

    http://www.driverheaven.net/reviews/accel/ with an x1800

    http://www.neoseeker.com/Articles/Hardware/Reviews/accelerox2/4.html with an x1900

    In any case. Not a basis for a sound (excuse the pun ;) ) arguement.
