Antwort Why not 128-bit OS? Weitere Antworten – Why is there 32-bit and 64-bit
What does it mean if my PC is 32-bit or 64-bit The bit version of your Windows PC indicates how it handles data. A 32-bit PC processes data in smaller chunks, while a 64-bit PC can handle larger chunks, which often results in better performance and compatibility with certain software.A 64-bit register can theoretically reference 18,446,744,073,709,551,616 bytes, or 17,179,869,184 GB (16 exabytes) of memory.Thus, 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, and are given in § History.
Is 32-bit faster than 64 : In conclusion, 32-bit operating systems are less utilized nowadays as compared to 64-bit operating systems. However, 64-bit is preferred because it is faster, has more memory, and can present graphics better than 32-bit.
Will we ever have 128-bit computers
As of 2022, there are no 128-bit computers on the market. A 128-bit processor may never occur because there is no practical reason for doubling the basic register size.
Is 128-bit faster than 64-bit : Between 128 bit and 64 bit versions of same graphics card, 128 bit would have better performance in games. Since GPU cache can not hold all the game content, eventually some data will be streamed from video memory to GPU. There, 128 bit will have advantage over 64 bit.
128-bit and 256-bit AES both have their pros and cons. AES-128 is faster and more efficient and less likely to have a full attack developed against it (due to a stronger key schedule). AES-256 is more resistant to brute force attacks and is only weak against related key attacks (which should never happen anyway).

Are there any 128-bit processors
Thus, 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, and are given in § History.There are currently no mainstream general-purpose processors built to operate on 256-bit integers or addresses, though a number of processors do operate on 256-bit data.This is roughly 18.4 exabytes of RAM. High end CPUs at the moment can address up to 2 terabytes of RAM, that is a minute rounding error when you are considering exabytes of RAM. Heck, even the biggest supercomputer in the world at the moment has only 2.8 petaflops of RAM over 4,608 nodes. There's no particular limit.

Has AES 128 ever been cracked : A machine that can crack a DES key in a second would take 149 trillion years to crack a 128-bit AES key. Hence, it is safe to say that AES-128 encryption is safe against brute-force attacks. AES has never been cracked yet and it would take large amounts of computational power to crack this key.
Is there a 256-bit processor : There are currently no mainstream general-purpose processors built to operate on 256-bit integers or addresses, though a number of processors do operate on 256-bit data.
Will there ever be a 128-bit CPU
A 128-bit processor may never occur because there is no practical reason for doubling the basic register size. One of the reasons for migrating from 32-bit to 64-bit computers was memory (RAM) addressing; however, for all practical purposes, there was only a need for a few more bits beyond 32 (see binary values).
If you ask how long will it take to crack 128-bit encryption using a brute force attack, the answer would be 1 billion years. A machine that can crack a DES key in a second would take 149 trillion years to crack a 128-bit AES key. Hence, it is safe to say that AES-128 encryption is safe against brute-force attacks.128-bit and 256-bit AES both have their pros and cons.

AES-256 is more resistant to brute force attacks and is only weak against related key attacks (which should never happen anyway).
Is there a 128 core CPU : The 4th Generation AMD EPYC™ processor family includes general purpose and workload-optimized solutions. These processors include up to 128 “Zen 4” or “Zen 4c” cores with exceptional memory bandwidth and capacity.
