Do 32-Bit Apps Run Faster on 64-Bit Systems The short answer is: it depends. The performance relies on many factors that aren't necessarily connected to whether a system implements a 32- or 64-bit architecture.It is commonly believed that native 64-bit applications are faster than 32-bit applications, but that's not always the case. In fact, some 64-bit applications are slower because data structures tend to be larger in 64-bit applications (again, due to the larger pointers) and moving them around can slow things down.64-bit is mostly faster than 32-bit (sometimes considerably so). Some benchmarks here and here. There are some exceptions, but they tend to be rare. But code size and data size (if it includes pointers, or types that vary with 32-bit/64-bit) may be larger and that can affect caches.
Is 64-bit the best : Compared to 32-bit systems, 64-bit operating systems can address significantly more memory, leading to improved performance and support for advanced software and applications.
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.
How much RAM can 64-bit use : 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.
So for all practical purposes a 32 bit CPU will be faster than a 16 bit CPU. One that performs its designated task in the lowest time.
To install a 64-bit version of Windows, you need a CPU that's capable of running a 64-bit version of Windows. The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more.
Are smaller CPUs faster
Generally speaking bigger CPU, bigger dies, are faster cause faster transistors are bigger. Good example are cache memories where L1 is fastest, working at same speed as CPU, and cause of this must use faster, hence bigger, transistors and is smallest of all caches. Latest CPUs have L1 cache in 64 – 192 kB range.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.
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).
Why don’t we use 128-bit CPUs : 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).
How much RAM does 128-bit support : 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.

Speed: In a 16-bit microprocessor clock frequency is 5 MHz whereas in an 8-bit microprocessor clock frequency is 3 MHz so the speed of the 16-bit microprocessor is high. So in the case of directly addressable memory, 8-bit μp is limited to 16-bit μp.When it comes to recording, even at 16 bit, the noise floor is very low. So you could record at 16 bit and still have a decent amount of dynamic range. A more common practice however, and something of a standard, is to record at 24 bit. Simply because recording at 24 bit gives you more dynamic range to work with.
