Why Don T We Have 128 Bit Computers Yet It's practically impossible to predict the future of computing, but there are a few reasons why 128 bit computers may never be needed: diminishing returns: as a processor's bit size increases, the performance and capabilities improvements tend to become less significant. Yet, even though 128 bit computing would enable us to work on much larger numbers than 64 bit computing can, we still don't use it. as for why this integer length is important, it's not so.
Why Don T We Have 128 Bit Computers Yet 128 bit processors already exist, but they're not really practical for everyday consumer use because well, it's overkill. One of the main reasons why we don’t have 128 bit computers yet is that there is currently no pressing need for them. while 64 bit computers offer significant advantages over their 32 bit counterparts, there are few applications that require the processing power of a 128 bit computer. Have you ever wondered why we never had a 128 bit computer?timecodes0:00 intro0:07 why don't we have 128 bit computers1:47 processing integers and gloa. As of july 2025 there are currently no mainstream general purpose processors built to operate on 128 bit integers or addresses, although a number of processors do have specialized ways to operate on 128 bit chunks of data as summarized in § hardware.

Why don’t we have 128bit computers? ultimately, the key reason why we don’t have 128 bit cpus is that there’s no demand for a 128 bit hardware software ecosystem. the industry could certainly make it if it wanted to, but it simply doesn’t. While 128 bit processors would theoretically provide an even larger memory space and higher precision, they are not currently in mainstream use due to several practical limitations. fabricating a 128 bit cpu is currently quite complex, and the fabrication technology isn’t quite developed right now. The primary reason we don’t have 128 bit cpus isn’t because it’s impossible, but because there’s no compelling practical need. jumping to 128 bit addressing would allow for an absolutely astronomical amount of ram, far beyond anything currently conceivable or necessary. By far the most common case for native math operations is to address locations in system memory. speed benefits for algorithmic calculation are just a nice side effect. the big deal around 64 bit computing is the ability to address more than the ~3.8gb of memory supported by 32 bit.
