Apparently Nvidia has plans to bring the Geforce six series back to AGP
. The company is currently working on a printed circuit board that will make the 6200 AGP card possible. This will make it possible for Shader 3.0 to be available to all Nvidia's potential customers, not just those with PCIe compatible systems. Or, at any rate, this is the general plan, but there may be some technical issues. When the 6200 will appear on AGP seems unclear at this moment, but 6600GT AGP cards are already available and 6600 standard AGP are expected soon.
We are quite sure that those cards won't use Turbo Cache as the AGP interface is one way only and it's not wide enough for all of the data. This leaves Nvidia and its partners with two options. To base 6200 AGP on NV43-V chips used in 6200 standard or to base them on NV44 cards used in 6200TC.
This will put some additional pressure on ATI, as it still does not support Shader model 3.0. We know that ATI will chose the same path from R520 to all other future products but Nvidia definitely have lead over the competition as it complete generation weather we are talking about PCIe or AGP cards. ATI bridge chip is still not ready but it should be toward the middle of Q1 2005.
