The primary advantage of the 64-bit ISO is memory addressing. A 32-bit system is limited to a maximum of 4 GB of RAM, regardless of how much you have installed. A 64-bit system can handle significantly more—theoretically up to 18.4 million terabytes—allowing for better multitasking and higher performance in resource-heavy applications like video editing or gaming.
