I've been looking into this CUDA versus FPGA thing more, and it seems to be an ongoing debate even within the high-performance computing industry.  But then I found this little tidbit....

These guys figured out a way to automagicly map a FPGA with GPU-like 'stream' processors suited for the type of excecutions that a particular CUDA program uses.  Which not only allows a program written in CUDA to be used on a GPU to run on a FPGA without modifications, but also saves space on the FGPA by not implimenting functions not required for the CUDA program in question.  Potentially permitting more "streams" than would otherwise be possible.

I wonder how long it will be until some major GPU manufactuer such as Nvidia puts a FPGA on a graphics card?

Currently, however, a CUDA capable graphics card in a modern gamer system would be the best cost/performance value; if only because one still needs a graphics card anyway.

Going out of your way to buy a dedicated graphics card, in addition to the one required for a modern system, such as a 'Nvidia Tesla' card, is probably not a cost/performance advantage over a FPGA card bought for the same purpose and encoded with CUDA capable stream processors.


"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

- Carroll Quigley, CFR member, mentor to Bill Clinton, from 'Tragedy And Hope'
