The processes used for FPGA are VERY competitive with GPUs. Stratix 10 is at 14nm, for example. Stratix V was built using 28 nm process and that was at least 5 years ago - on par or exceed NVidia.
You can fuse more operations into DSP using FPGA and/or you can perform less operations per FLOP. One example is to avoid rounding and packing/unpacking when creating deep pipelines for floating point processes.
- vvanders 10y agoCheapest Stratix V I can find on digikey starts at ~$1,800 and quickly goes up to $10k for the bare chip in quantities of 24. For open source hardware I doubt you'll see people shell out the cost of a used car to be able to match modern ~$200 GPUs. I don't even what to know what Stratix 10 starts at.
- throwayedidqo 10y agoWow. These things just scream military use. My guess is phased array radar.
- leoedin 10y agoI worked on a space based imaging radar which used an FPGA. It cost mid 6 figures per chip... This was admittedly a space certified radiation hardened chip. Still alarming when you had to pick it up and carry it somewhere
- thesz 10y agoThe complete devkit solution is about $7K - https://www.altera.com/products/boards_and_kits/dev-kits/altera/kit-sv-gx-host.html https://www.altera.com/products/boards_and_kits/dev-kits/alt... The Xeon Phi board https://www.cnet.com/products/intel-xeon-phi-coprocessor-7120x-1-238-ghz-processor-board/prices/ https://www.cnet.com/products/intel-xeon-phi-coprocessor-712... is $4.2K..$5K The Stratix V board will not consume more than 60W when used as PCI Express card. The requirements for Xeon Phi is at least 250W. With a difference of ~200W, there will be difference in ~4.5kW/h per day or ~1600kW/h or $160 in hard cash per year (US average). Very probably more - getting rid of heat produced, etc.
