- lnsru 9y agoThank you very much for the link!
- godelmachine 9y agoHi Insru - how do you think GPUs would fare taking into consideration alain94040 's metrics?
- lnsru 9y agoPlease look at this pdf: https://www.nvidia.com/content/tegra/embedded-systems/pdf/jetson_tx1_whitepaper.pdf https://www.nvidia.com/content/tegra/embedded-systems/pdf/je... There is a table on page 9 and it claims, that Titan X can make 3216 img/s while TUL-KU115 FPGA board can make only >1000 img/s. This KU115 chip has a project price of ~$2000. Real time capability is nice, but that’s still expensive.
- godelmachine 9y agoThanks for this PDF :) Do you think TitanX has real time capability?
- lnsru 9y agoI am FPGA developer and have not much knowledge about GPUs. I just can make a guess, that no one can guarantee execution time on GPU. There are all little details well defined in FPGA design and result is always available after defined delay.
- fnl 9y agoThough wouldn't it be far more interesting to compare the latencies at these rates, than the throughput? Roughly similar price and throughput, but very different energy efficiency and possibly latency could be rather significant for quite a few applications.
- lnsru 9y agoXilinx has prepared some marketing material regarding latency: https://forums.xilinx.com/t5/Xcell-Daily-Blog/Xilinx-reVISION-stack-pushes-machine-learning-for-vision-guided/ba-p/754387 https://forums.xilinx.com/t5/Xcell-Daily-Blog/Xilinx-reVISIO...
- godelmachine 9y agoFor some reasons the Xilinx link is not opening.
- lnsru 9y agoStrange. It’s works here. Try this: https://www.xilinx.com/support/documentation/backgrounders/revision_backgrounder.pdf https://www.xilinx.com/support/documentation/backgrounders/r...
- godelmachine 9y agoGot it! Thanks :)
- sannee 9y ago> This KU115 chip has a project price of ~$2000. That seems odd - just the XCKU115-2FLVB2104E FPGA goes for $9000 on DigiKey.
