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).In computer architecture, 128-bit integers, memory addresses, or other data units are those that are 128 bits (16 octets) wide. Also, 128-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.As of now, 64-bit is the highest commonly used architecture for general-purpose computing. However, there is ongoing research and development in computer architecture, and there are experimental and specialized systems that use higher bit architectures, such as 128-bit or 256-bit.

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.

Is there a 128 core CPU

AMD EPYC Milan 7003 Series – up to 128 Cores Workstation PC.

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).

One of the main challenges is hardware support. Current consumer CPUs and memory systems are predominantly 64-bit, and there's no immediate need for a 128-bit OS given the vast addressable memory space and computational power provided by 64-bit architectures.

What is 256bit vs 128bit

The main difference between 128 and 256-bit encryption algorithms is the length of the secret key that they use. The 128 and 256 in AES-128 and AES-256 means that the two algorithms use 128-bit and 256-bit keys respectively. The longer the secret key, the harder it is for an attacker to guess via brute force attack.This microchip with 1,000 processor cores was designed by graduate students in the UC Davis Department of Electrical and Computer Engineering. The chip is thought to be fastest designed in a university lab.AMD Ryzen™ Threadripper™ 7980X

Is a 128-bit GPU good : Yes, Higher bit rate is better i.e. As you go up in bit rate in general the cards perform faster… 64bit, 128bit, 192bit, 256bit, 512bit but other factors play a part in performance in combination with bit rate.

Is there a 512-bit GPU : Some GPUs such as the Advanced Micro Devices (AMD) Radeon HD 2900XT, the Nvidia GTX 280, GTX 285, Quadro FX 5800 and several Nvidia Tesla products move data across a 512-bit memory bus.

Intel Core i9-14900KS becomes the fastest CPU ever hitting a 9.12GHz overclock, breaking multiple world records | TechRadar.Single-core – one processor on a die. Since about 2012, even most smartphones CPUs marketed are no longer single-core; Microcontrollers are still single-core, while there are exceptions. Multi-core processors – a 'few' processors on a die, e.g. 2, 4, 8.
