With all the problems at the moment with ati and nvidia having to stick 2 gpus on one board to get the performance we need / want, why have none of them bought into powervr tech? all they have to do is licence the bloody thing?

i really cant understand the 2 companies for not jumping on powervr tile based rendering ? smaller amounts of memory would be needed etc , and aa would not make such a performance hit on the card ?.

Ati stuck there neck out with the r 600 and the aa permotmance saying that they are doing things a new way , it didnt work

Nvidia seem to be struggling to better the 8800 cards so some one with comman sence tell me why they wont licence the TBR tech?
 
ATi probably cannot afford the PowerVR tech, and Nvidia are sitting on something like 90% market share, so why bother?

Nvidia won't bother until their position is threatened. (although I see them taking on Intel in the IGP department more tbh)
 
Tile based rendering was superior to Z-buffer at that time. I don't know how it would cope with solutions that ATI and Nvidia are using now. In addition from what i remember there were some issues with TBR and AA but i could be mistaken.

I think it was AA aswell but cannot remember
 
Nvidia aint struggling to better their 8800 cards, they just wont move on from them as they have no competiton for them, if ATi could compete with them they would have given us their next gen long before now, but seen as their cards from 2006 have still not been caught/bettered, they aint gona bother, so still gona churn those old cards out today.

There is a little issue where you can have FSAA with zero performance hit. It’s a bit of a bad one, PowerVR are trying to get a performance hit in there somehow, so they are on par with ATI. PowerVR call the problem FSAA for Free. :p ;)

You might be thinking of the old 1998/9 chip the first 3dcard with FSAA. It had a 50% preference hit for x2 FSAA and 75% performance hit for x4 FSAA due to using supersampling




"Nvidia are sitting on something like 90% market share, so why bother?"
Nvidia are more like 15% or 5% or less if you include mobile markets.
Did you know it’s a PowerVR chip in the Iphone and N95 among others? PowerVR are doing pretty well as most mobile chips are from them. By mobile I dont mean laptops but small device's like sat navs and phones.

Intel holds the bulk of the shares for the moment but it seems like they will have to get their act together in that department aswell since both AMD and Nvidia have plans for that market and with the experience both companies have in making video chips that will be, in my opinion in a place to produce better on-board solutions than Intel.
