9800 GT to Use 55nm Manufacturing Process

[Jimmy 2004]

According to VR-Zone, NVIDIA's upcoming GeForce 9800 GT graphics card will be the first desktop GPU from the company to be manufactured using a 55nm process. The new chip is called the G92b core, and should help NVIDIA to reduce its costs. The current G92 core uses a 65nm process.

wonder what this mean for performance, how much better it will be?

 

[thebeephaha]

It will likely run cooler and overclock higher. Kind of like the G92 was to the G80.

Similar performance, better in areas, but not a significant change, just a nice optimization.

 

[jbunch07]

true true....hasn't ati been using 55nm process for a while now? seems to be working for them as fars as higher clocks go.

I don't foresee better overclocking for this card than the 8800 GTS 512.

The 10nm decrease will lower temps but it will either be undervolted and have a 750/800 celing, or the "b" version of the G92 will (likely) not be well constructed enough or geared towards better overclocking, just like the RV570 (X1950 Pro for the young ones), with which the only thing that improved aside from the manufacturing process by (also) 10nm (90nm to 80nm), was the temperature.

Besides, a "GT" version will (again, likely) gain a decrease in shader unit amount, to 96 or 112, much like the 8800 GT. So the performance, in all, will not be worth it, just like the 9800 GTX, when you can get it's 8-series, intrinsicly identical twin brother, for less.

I guess they`re refining the production process and setting everything up for the 9900 - the real new series.

Well, Nvidia can't release an 9800GT that is faster then the GTX, so they will probably release it with only 48 shaders. With a faster core it can still beat the 8800GT...

 

[WarEagleAU]

Maybe be something similar to AMDs offering. the 55nm process reduced heat and power and offered better OCability.

Nvidia is totally lost with the Naming Sequence, But then again with the 9800GX2 having a Shelf Life of 3 months, im sure the 9800GTX will follow suit until the 9900GX2/9900GTX come about.

i dont think it will be 48 because the 9600 has 64 and they cant make a 9800 slower than the 9600

 

[calvary1980]

it's probably going to be 112 Shaders.

[eidairaman1]

probably 96

 

[magibeg]

Probably run by magical faeries...

 

[calvary1980]

doubt it, im also not convinced this is going to be like a 9800GTX to a 8800GTX in performace, I think the new 9800GT is going to be faster than a 8800GT with the new die shrink and it makes sense with the EOL articles ive been sending in suggesting the 8800GT, 9600GT and 8800GS are not going anywhere.

should help NVIDIA to reduce its costs

Nothing new there. Like I said in the 9800GX2 EOL thread, this has been nVdia's strategy starting with G92. Why should nVidia release any monster cards when AMD's latest offerings are still struggling at pretty much every tier. The only category where AMD is (was) outperforming nVidia, for a while at least, was in the price/performance ratio category with their cheapish 3850/70 parts. But plentiful availability of cheap G92 based cards in early 2008 ruined that for AMD in a hurry.

I wouldn't expect any monster GPU's from nVidia this summer, unless AMD releases some monster GPU that has enough kick, but that ain't gonna happen. I have no doubt that nVidia has a 32-ROP 256 SP monster GPU ready and waiting in the shadows, but they aren't going to release it unless compelled to by AMD.

So, if G92 was budgeted and cut down G80, this G92b should really be something to see.

+1 Thats true, sounds EXACTLY like what AMD did a few years back with the X1950PRO... X1900GT (R580) with full quads, then cut down and die shrinked into a RV570 for the X1950PRO.

Except the last bit, this card will sell like hotcakes due to its pricing-it will be priced the same or cheaper than the 8800GT-thats after a few months however after the lame hype and pricing that retailers put on "new" things. Die shrinking makes stuff cheaper to make because you use less of it, and not everyone overclocks anyway.

I reckon the R700 will own white the GT200 will be a power hungry and late-to-market card

I think so too. Just look what Nvidia could do with only 64 shaders on the 9600GT.

256 SP's, 1GB GDDR5 memory and 55nm core, voila, you got yourself the Geforce 10

How do you reckon that?

I agree with you on this one and I think they thought they had got the whole market tied up with their cards. They don't realise they are totally confusing there customers at the moment.

They need to slow down and take into account where they plan to go in the future. It took me a long time to go over to nVidia as me being an ATI fan but since going over to nVidia cards namely the XFX range I have never had any problems with there cards, but hey where to now as there is so much to choose from.

isnt GDDR5 an ATI exclusive?

I reckon that's unsubstantiated bullshit
