Comparison With CUDA
| The neutrality of this section is disputed. Please do not remove this message until the dispute is resolved. |
Two comparisons have been drawn between CUDA and OpenCL since its inception, and both arrived at the same conclusion: if the OpenCL implementation is correctly tweaked to suit the target architecture, it performs no worse than CUDA. Because the key feature of OpenCL is portability (via its abstracted memory and execution model), the programmer is not able to directly use GPU-specific technologies (such as inline PTX) unless they are willing to give up direct portability. CUDA is more directly connected to the platform upon which it will be executing because it is limited to Nvidia hardware. Compiler technology for both standards supported by Nvidia's toolkit is based upon LLVM and compiles to Nvidia's PTX instruction set abstraction.

Famous quotes containing the words comparison with and/or comparison:
“[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
—Sarah M. Grimke (1792–1873)
“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
—Shusha Guppy (b. 1938)
