The New and Improved "G80 Rumours Thread" *DailyTech specs at #802*

I don't have any reason to play the less samples game as I'm not trying to sell a real GPU based on small fps advantages over a couple of games. The algorithm is just a modification of the example algorithm in the OpenGL extension for anisotropic filtering that takes into account the diagonals that I came up a couple of years ago. Much, much later I discovered that someone had already published that algorithm long time ago (in a paper about a chip called Texram and it's also explained and referenced at Compaq's Feline papers) and that it was basically the same one I implemented. The function that implements the AF algorithm can be found in the /emul/TextureEmulator.cpp file if you are interested.

The ISPASS paper has some numbers from those three games but not exactly in the way you want them. Of course I could just produce them but I don't have the time right now (maybe the weekend if I'm bored).

And I can't find reasonable just below 2x samples in neither of those three games when almost all of the textures have trilinear set and it's likely that most texture requests are getting at least 2x AF.

I think I may try to set a configurable 'precission' (as I use x86 float precission, 32 bit for texture computations, 64 bits for rasterization, to avoid having to implement a fixed point library) for the trilinear weight and drop down to one mipmap when the weight is completely biased to one of the two mipmap levels to see how much that affects performance.

 

More filler until the time

What was the original power of 3 that nvidia had ? It was all card features I think, now it is very Intel aligned

Makes you the daddy .. now that does make it sound like an expensive past time !

 

SLI+HDR+SM3.0

 

Probably the 3rd component should be their own x86 CPU

 

Deja-vu

 

It's the same cooler that GeCube uses on the X1950Pro FZ Cool Fan HDCP Edition:

Yes.

Edit: Crap, i wanted to edit my previous post. >_<

 

This has a Peltier cooler stuck on the bottom of it though. Not keen on TEC coolers with air though, the heatsinks and fans never seem to have the capacity and really you need liquid cooling.

 

Launch is here, so please take discussion about to the G80 Architecture thread!
