Jan 22, 2017 · Without FP64, scientific research guys can't even try a demo of scientifically important gpgpu software that uses FP64(and even games could be using some double precision on an occasion). Without FP32, game physics and simulations would be very slow or GPU would need a nuclear reactor.

Jun 18, 2022 · Why is the performance loss from FP32 to FP64 so much greater than the performance gain had from moving from FP32 to FP16? I recognize that this is not always the case for each GPU, but my impression is that for many GPUs, the gains had from going from FP64 -> FP32 are much larger than the gains had from going from FP32 -> FP16.

Jun 1, 2013 · Thus, it would have been great if we could use fp64 on HD graphics through OpenCL. I have a feature request that perhaps Intel can release limited fp64 support through a vendor extensions (something like cl_intel_fp64) where a subset of cl_khr_fp64 can be supported. AMD used to do something similar through their extension cl_amd_fp64.

Sep 3, 2019 · 2-Regarding if those FP64 cores are removed completely and are not actually disabled on laptops, FP64 is enabled on 6th, 7th, 8th and 9th Generation processors (desktop and mobile) including Apollo Lake and Gemini Lake. In this case, please check with the Laptop manufacturer for any potential customization that is outside Intel's control.

May 16, 2016 · I'm getting a message saying that the extension is unsupported (error: OpenCL extension 'cl_khr_fp64' is unsupported) However some quick googling shows that it should be working fine for Xeon processors. Here are the specs: processor: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz. OS:Red Hat Enterprise Linux Server release 7.2 (Maipo) driver info:

May 28, 2015 · I can find the cl_khr_fp64 extension, required for double precision, on a Ubuntu 14.04 running on Amazon EC2 using Intel Xeon and Intel Code Builder for OpenCL API 2015 for Ubuntu:

Oct 9, 2014 · @alanmac I think Nvidia target their fp64 performance to match Intel CPU fp64 performance. ie.so that your not at a disadvantage vs the cpu when targeting cuda/opencl for you fp64 application. AMD doesn't do this, they try and give as much as they can without significantly compromising their general graphic (game) performance.
