Well yes, in fact S3 does have some big plans and even a well designed roadmap. But that's all since further than that, I haven't seen any new products coming from them for maybe 6 months. It seems that all this time they have been preparing to counter the attack launched by Nvidia's G80 line. And as always, in the battle to win customers, S3 is planning to skip several intermediary steps and will jump directly into the DirectX 10 boat.

Ok, so S3 is planning to produce Shader Model 4.0 cards. That's good I guess since they are releasing 5 different lines of GPUs all of them being DirectX 10 capable. First come XD2/D2 sampling right now and with a final product out in 9 months. The 90nm GPU supports HDMI, Dual Link DVI, LVDS and HDTV. The chip comes with three "Execution Units", however no additional information regarding them has been released. GPU has a clock speed of 1GHz and supports quad-channel 128 (XD2) or dual-channel 64-bit (D2) interfaceDDR-2, GDDR-3 and GDDR-4 memory chips will be used. The resulting PCB is said to be relatively simple comparable to Ati and Nvidia designs.

XD3/D3 will be the first 65nm GPU produced by TSMC and it will sample in 6 months. The GPU is rated to work at 1.2 GHz and has a dual-channel 128-bit or 64-bit memory controller. Both chips feature AcceleRam (probably something similar to Turbo Cache/Hyper Memory) and MultiChrome (similar to SLI/Crossfire).

As for the DirectX 10.1 parts, not much can be said since no one can actually tell what improvements will the new version bring. What's pretty sure is that all the new cards will use the PCIe Gen2 interface. When asked about these GPUs S3 specified only a few details.
XE3/E3 will probably be a 1.2GHz dual-core GPU with a simplified memory controller 128-bit wide and will use DDR3, GDDR-3/4 and maybe GDDR-5 memory. XE2/E2 will use 5 cores and should have a 256-bit (XE2) or 128-bit (E2) memory interface. XE1/E1 is most powerful chip that S3 plans to launch by the end of 2008, with eight cores, quad-channel 512-bit (XE1) or 256-bit (E1) and support for GDDR-4 and upcoming GDDR-5.
