UPD2: spring 2023, you can buy P100 as low as 200$ on eBay. From modern ones Intel ARC is interesting, but I haven't checked it myself yet (UPD it looks like there is no native support of FP64 in ARCs, removing). Best performance per dollar is of Titan (Black) and 7990/7970/280x. Anyone who would disagree is just a shill.Īlmost exhaustive list up to 0.5 TFLOPS. As far as I can tell, double precision is generally supported for Radeon HD x9xx graphics cards, may or may not be supported for x8xx and x7xx, and is probably not supported otherwise (e.g., 圆xx, x5xx, and x4xx). Pure greed and crap engineering by the NVidia people who know they can shaft you if you want to do complex math ( like add and subtract ) with circa 1988 math in FP64 bits. If the compute power quoted doesnt specifically mention double precision, it should be interpreted as single precision.
AMD RADEON VEGA FP64 DOUBLE PRECISION DRIVER
Even worse you need a special license and driver to use a GV100 if you own one and NVidia jams you again. That is why the Keplar worked great and then the FP64 was taken away and hidden. The gamers don't give a damn because they just want pixels on the screen but anyone doing real work gets jammed hard for maximum dollars. There simply aren’t any other current-generation cards priced below 2000 that even. While most GPUs support FP64, unless you pay for the really high-end scientific computing models, youre typically getting 1/32nd rate compared to FP32. As soon as NVidia figured out they could jam people for big money the FP64 capability suddenly went away and everything after the Keplar was sold as brain damaged. At 3.5 TLFLOPS of theoretical FP64 performance, the Radeon VII is in a league of its own for the price.
AMD RADEON VEGA FP64 DOUBLE PRECISION 64 BIT
Everyone on the planet can do addition and subtraction and other operations with 64 bit floating point and it has been that way for well over 25 years. AMD Ryzen 5 3400G with Radeon RX Vega 11 Graphics Specifications. So the ability to do IEEE754 math like the year 2008 and the original 1988 specification was removed. GPU span (Turbo) FP16 (Half Precision) FP32 (Single Precision) FP64 (Double Precision) 1.
NVidia figured out that scientists and engineers can be jammed for massive dollars and thus the NVidia folks simply de-tuned and killed the FP64 capability on everything they sold EXCEPT for stuff that they can sell for $10,000 and up.
