Well You got to love Nvidia. Just look how they market things. 7800GT vs.7900GT

[DARQ MX]

yea, I know it is a little old to mention now, but I just thought of this now. And their plan on marketing. It is smart I give them that, but it rather is unfair to their customers in a short peroid of time. Now I am unbias towards both brands so don't say I am a fanboy. lol

So some history and wrap up. This is all from my mind and remembering 7800GT specs. So bare with me if it is off a little. Also some 7900GT specs, I gathered recently.

So the 7800GT's come out August 13th(I think) Aprox 6-1/2 months ago. Great line of cards decent price compared to the 78GTX and a lot of quick brand support.

Now 6 months come by and The 7800gt's are discontinued by Nvidia stops production and the New G71, 7900GTs come out with...

7900GT's come out with(Depending on the brand)

1. A 300mhz memory clock,
2. 4 extra pipes,
3. Probably Better faster Ram speed, ns.
4. Cheaper price, about $75 dollars less from the highest end 7800gt's to highest standard 7900GT so far.

5.About 25mhz more on the core (again depending on the brand).

6.Average 7800GT in mark05 got high 76xx scores stock.

7.7900GT's gets high 78xx stock on Mark05. (Pretty much GTX scores)

8.Now I suppose the 7800GTX users got hit a bit harder than the GT owners cause the 7900GT is pretty much a 7800GTX and paid almost twice the price.

9.New core G71 vs. G70, I don't know if the G71 has a new manufacture process or not.

10.most likey better Heatsinks and some made out of copper.

Now with all that said, Does it make you want a 7900GT more? I mean wow, Just look at what you get compared. I am still keeping my 7800GT cause it is still a great card and can max out most games(besides fear) with my system and I will not be getting a new card until the DX10's come out.

7900GT @ 450/1320 = Meh
7900GT @ 565/1700~ = 7800GTX 512 @ <$350

You can OC these G71's that much!!! How stable?

Not to mention, volt modded 7900GT's are hitting 650-700 core and 1700-1800 mem, which practically puts them at 7900GTX levels of performance. And the mod is completely straightforward too, all you need to do is draw a line on the board with a conductive pen.

Just be careful when volt modding. The increase in performance is awesome, but not all cards handle increased voltage the same. I'd suggest improved cooling if you were to volt mod one of these bad boys.

 

[DARQ MX]

I would never volt mod something expensive.

It bumbs the voltage to 1.4, but whats the stock voltage on a 7900GTX? The G71 can proabably handle that much voltage.

 

[NoDamage]

Yeah, the stock voltage on the 7900GTX is 1.4v.

 

[Madwand1]

Can't fault nVIDIA for trying to make money. When they had the 7800 series, they sold them, now they can do better... But if your approach is to look at each incremental gain and think "wow, I want that", then of course you'll be in a perpetual upgrade cycle. If you think the 7900 is great, well let's see the G80 when it comes out...

Agreed.

 

[TheRyuu]

Is there any software way to modify the 7900GT's voltage?

I realize the mod is straightforward, but I would like to avoid it at all costs, even though I am on watercooling (or will be very soon).

Nope. Only hardmods at this point.

That is a pretty slick way of voltmodding the card as it avoids soldering. Does anyone know if the power circuit can handle that much voltage? I know that the 7800GTs required some extra attention to the power circuit area when voltmodded.

Well there are other subtle differences like tweaked ROPs on the G71 for improved performance when HDR is used. Also, 50% increase in performance for dynamic branching due to the shortened pipeline of the G71. (well thats the theory so far for the increase in dynamic performance). Not to mention less transistors, 90nm lowk and pretty much the power consumption of the 7900GT is same as a X1800GTO at load!

As far as I can tell right now, the 7900GT and 7900GTX in terms of voltage, that seems to be the only difference, because on the 7900GTX it's already grounded giving it 1.4 volts.

Now I'm taking a guess, but I gather the card should be able to hadle it, and the core should definitaly be able to handle the voltage cause thats what the GTX's run at. Pretty nice 24/7 volt mod. Insanely easy too.

Key point.

4. Cheaper price, about $75 dollars less from the highest end 7800gt's to highest standard 7900GT so far.

BS point.
My 7800GT around release was the same price as the 7900GT's around release. This is for low end though, which is what you should look at not, high end for price comparisons.
