WebFeb 20, 2024 · It is now ~60 faster than the numpy code. Still a factor of 4-5 away from cython and pythran Couldn’t help noticing this fact. Since both numpy and cython are C based, we have to conclude that C (cython) is ~300 times faster than C (numpy). Note, sorry if my quote makes think that the quote is from @Henrique_Becker. It’s not. WebDec 13, 2024 · Not sure if you can do explicit SIMD stuff, so in that regard one has more optimization opportunities in C/C++. Though, as said, to really get the same performance as C/C++ code, your Cython code has to look very much like C code. So much so, that I’d rather directly write C/C++ code instead, hence my original suggestion. flash card driver for windows 10
