Just wondering if either of these provide a distinct advantage in processing speed over the other and what sort of difference in speed could be expected. (Especially FA@H, C4CW and HCC)
Thanks |

Windows 7 64 bit should be faster due to it's 64 bit capabilities.
----------------------------------------And welcome to the foruns  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

Linux 64-bit has a much faster compiler. Years of using the very slow GCC compiler for basic x86 code have been magically ended by a new 64-bit compileer thatseems to use all the modern enhancements that 64-bit CPUs have.
Windows 7 64-bit does not seem to show a similar astounding improvement over 32-bit code but it shoul produce assembler code that runs at least 190% faster just because the analogous instructions are faster in 64-bit CPUs. I do not have any hard data on this so my post is speculative. Lawrence |
