    Is it really though that much cheaper? If I have to sacrifice 5% performance which would result in potentially millions in dollars of revenue would I take the risk?

      They don?t need to reverse engineer the driver because AMD give the specs to the Devs and if something undocumented you can ask the AMD ppl.

      Some of the "radeon" driver devs are employed by AMD an some by Redhad an AMD partner.

        Well lets put it this way, I design boats as well as my computing life, manufacturing wise that is simple as it takes typically less then 4 hours to assemble a boat but to gain that extra 5 mph out of the hull it took 18 months of analysis, design and simulations to find that "sweet spot spec" that allowed that performance difference. Assembly wise it made no difference. I guess it all depends on the product being designed. Ask any farmer as well about what they would do about their combine if they had a chance to talk to the engineer.
        well, your exemple assume heavy R&D using actual production tooling. Could be wrong, but I was assuming that hardware was split in R&D between elementary science, new product engineering and manufacturing technology.

          .
          Well again that is not entirely true, yes AMD has released specs to a majority of their IP but there is still a fair amount that will remain shut out due to licensing and the likes. UVD just as an example.

            are you saying that AMD finally released *ALL* the technical specs needed to create a ''perfect'' and ''complete'' driver for every card?

              Actually all the boats are assembled with about $300 worth of hand tools found at your local Home Depot. Assembly was never really a concern.

                small changed of subject... what about BIOS? thats old tech. Hardly anything of value

                  Oh, I tought you were talking about Cup of America style of boats. Because I do work as ''metrology'' engineer, and in every industry I have seen, about as much time is spent on ''how to build the dam thing'' than on the actual conception. if not more

                    The boats I designed were actually "extensions" to personal water craft (seadoos as referred by some). Take a formula 1 boat or a deep V but use a PWC as a powerplant and you get the idea of the mass number of options available. Mounting brackets cost to produce about $20 to make and was installed with a rachet and a wrench but the R&D that went towards the proper mounting height, alignment, etc far exceeded the materials, mold and manpower it took to produce those.

                      I cant promise this (Im not an dev) but in the past someone says that all needed Informations are out.
