i think I understand that, but I don't understand why it won't rival a dedicated GPU. A GPU is very much restricted to be SIMD, while it seems to me that you could program an FPGA in response to the data - either many SIMD processors or a a few SIMD plus some logic that combines results, or ...
- rcbuse 17y agoWell, I should say, it won't rival a dedicated GPU once you factor in cost.
- andrewcooke 17y agoah, ok. thanks.
- coffee_bender 17y agoI should also note that an FPGA will not perform as well as a custom ASIC (such as a GPU) in terms of speed, power, or price (in significantly large quantities). An FPGA can be a very good options for moderate to low volume applications. You are correct with your description of a potential FPGA application. I would say it could rival or exceed the performance of the GPU solution.
- aswanson 17y agoYou would need to do on the fly reprogramming which is slow. The game designer would have to be intimately familiar w the fpga architecture and the game software complexity would increase ridiculously. Fpga density cannot rival dedicated gpu gate density for dedicated rasterizing, etc. I doubt performance would improve at all. Game computations are dominated by what gpus are built for.
