I prefer NVicodine.

Either way, we'll see what happens monday. For now, pricing is likely the famous "pre-order gouging" that we've come to know and hate by this point... It's a common thing for pre-orders to end up costing more than when the product is actually released.

$799 though? That's just pushing it. Shame on MWave :slapass: .

So what we know vs the eVGA model at Zipzoomfly...all vs TheInq

Nvidia managed to clock its new cards to 550MHz and can still cool them with air. We believe that Nvidia tweaked its existing PCB design big time so managing to get those cards to such high speeds.

470 vs 580 is a difference that is just too big...that's why I'm guessing the 470 isn't right....or just a very slow card compared to the OC'd ones.

Default clocks are set at 550/1800MHz, and every manufacturer can choose a variation.

Sow...what can we expect? 470Mhz? Not very likely is it? (would be dissapointing) 570 looks more like it.....typo? 7 days to go.

Well...

After searching EVGA there's no sign of the 7800gtx 512mb there, and ZZF has taken the 512mb 7800gtx off their site.

Looks like it WAS a mistake after all. Likely done to generate more traffic to their website.

Again I say it, it's been removed, no cause for alarm, it's not real.

Hey guys want to here something mysterious??? I posted the same info I heard in the EVGA thread at their forums and within minutes my post magically dissappeared. Nothing, no link to zipzoom/mwave or anything. Like it never existed. Haven't tried posting again though...... BTW the post did show up at the moment I posted so I am not on NVrack lol...

*prays to the NDA gods that ate my posts...*

i think it wont be 470 more likely 520~550 that is almost 100mhz more in core speed that is a lot :slobber: i want bench

I'm gonna take a little break and see what will happen...I still have to work this week (and my boss is gonna kill me if I hang around the forums all day :D)

I'll see what will happen... :)

Hmm, what's this?? A brochure that some vendor (starts with ZZ) accidentally published. Hope the spec is a typo. 570 would be nice.

470 core would be a little disappointing in light of all the hype. The collateral is dated 10-21-2005.

470 core :stick: :slapass:

470/1700 stock clocks?

Me thinks the XFX at 550/1730 might be indicative of how well these cores OC ;)

I gaurantee the eVGA has a delta. I looked through the leaked XFX BIOS at 580/1730 and it had no delta defined. That translates to a 540 root core in current GTX flavor. With the extra voltage, 1.45 VCore, maybe that's what it can deliver on the factory OC'd cards. So, 470 could actually be the new reference clock value. A decent 40 Mhz bump on the core over the previous 430. After all, it is still the 110 nm core. It all sounds about right with a tad more voltage.

Compare that with the Leadtek 7800 GTX Extreme I had that could do 550 with a delta (590 net) and no volt mods using the same Quadro heatsink and it all looks very possible. Too bad the Leadtek's memory was not as good as it could be (1350 tops). Still, if you can get a 540 MHz factory OC'd card (580 net, which is coincidentally the number thrown out by TheInq) and 1800 Mhz memory with a small OC, I would be more than content.

Rumours at EVGA forums says the modell with watercooling is supposed to run 550GPU and 900MHZ ram at a price of $560.
But this is just rumours, and hearing that the moderator was wrong about 512bit interface i dont know what to belive there =)

lol or 90nm for that matter :p:

I dunno what to believe too....I guess the OC'd versions run in the mid 500 range....stock cards? lol....Noooooo idea.

Nice. A paperlaunch that is vaporware. I smell BS marketing strategies. I doubt that pic in the first post is even a 7800GTX with 512MB. Like many have already mentioned, it looks identical to the leadtek one.

Looks like those waiting are going to be in for a real expensive treat :slapass:

lol.....paperlaunch? Vaporware? I think you just replied to the wrong thread, the other thread is this one :

http://xtremesystems.org/forums/showthread.php?t=79331

Maybe you made a mistake calling nVidia paperlaunchers? I dunno.

Wouldn't be much of a Leadtek if it has an XFX sticker on it doesn't it? :slap:

And I'm sure they also changed the bios name to XFX with 580/1730 freqs :slap:

@Ahmad
paperlaunch? the 7800GTX512 hasnt even been launched yet so why a paperlaunch?

Ignore ahmad guys, he's been flamebaiting everything positive for NVidia for awhile now...

Ahmad, I don't know what your major malfunction is, but do you even know what a paper launch is?

If there was a paper launch, and it was all marketing BS, there would be no need for an NDA, now, would there? And, the cards are already moving through the channel. Some e-tailers have even been brave enough to accept pre-orders.

Guys, your views are overly simplistic. A more accurate way to figure out the power of an ASIC (and even this is overly simplistic) is to use P=1/2CFV^2. C=capacitance, F=frequency and V=voltage. As you increase the voltage you can see that power goes up radically. If you increase voltage you will always increase current as well. As for smaller process nodes, there are many node specific dynamics that will factor into the overall power consumption. It's not as simple as just plugging one or two numbers into an equation.

But using the simplistic equation above, you can figure out roughly how much the dynamic power will increase by increasing the applied core voltage and increasing the frequency. Then there's leakage on top of that. ;)

Or, with the exact same # of transistors, you can have reduced power.

grayskull...you fail to mention the difference between power usage and power consumption.....

This isn't sounding good. It looks as though someone got their info wrong (Inq), and we've been hyped for nothing.

Eh, if they're wrong, atleast it still has 1.1ns ram.

However, that still doesn't explain the XFX stock bios with 580/1730 clocks. Considering NVidia made him take it down, there's definitely something to that one....

Also, remember, it's very possible that the 470 on that ad was a typo, 4 and 5 are nothing more than a click away, and I've seen worse typos on websites, as I'm sure we all have...

If it's not atleast 500mhz core though, I'm just going to continue waiting, after all there's still another fish in the sea.
