Antwort Is 32-bit Windows slower than 64-bit? Weitere Antworten – Is 32-bit Windows faster than 64
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.Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes).Why use 32-bit instead of 64 32-bit used instead of 64 bit is compatibility with older hardware and older software.
Is 64 bits faster : 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.
Is 32-bit good for gaming
Short answer is if you're using more than 4GB of RAM you'll need a 64bit version to see it and utilize it. In general, for gaming, having more RAM is a good thing. Getting a 32bit OS will limit you for that type of use. Especially as time goes on, game requirements increase, etc so again, 64 should be the way to go.
Which is better for old PC 32-bit or 64-bit : The 32-bit versions have an addressable memory of exactly 232 bytes. That's 4,294,967,296 bytes, or 4,096 megabytes (4 GB). On the other hand, a 64-bit system offers a memory of 8 GB, 16 GB, or more. 64-bit versions therefore use their capacities faster and more efficiently.
The simple answer is “YES”. One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4GB of RAM. A 64-bit register can theoretically reference a maximum of 16 exabytes of memory. This is a million times larger than 32-bit systems.
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.
Are 32-bit apps slower
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.32-bit applications optimized for a 32-bit system won't gain any advantage from running on 64-bit hardware. To the contrary, penalties from emulation and compatibility issues described above may apply. However, non-optimized applications may gain some performance from running on 64-bit machines.64-bit programs require more memory to run than their 32-bit versions. So on older 64 bit machines, with less RAM onboard – it makes more sense to run a 32 bit OS. That situation can easily be mitigated by installing more RAM. But if you don't have that luxury – then sticking with a 32 bit OS is your best recourse.
4GB RAM
What are the RAM limits of a 32-bit operating system All 32-bit operating systems have a 4GB RAM limit.
Is 64-bit better than 32 for gaming : A 64-bit system can have a positive impact on gaming, especially for modern and resource-intensive games. With a 64-bit operating system, games can access and utilize more memory, allowing for smoother gameplay and reducing the likelihood of performance issues caused by insufficient random-access memory (RAM).
Does 64-bit take more RAM : A 64-bit system uses 64-bit memory addresses, which allows for a much larger addressable memory space compared to the 4 gigabytes (GB) limit of a 32-bit system. This means that a 64-bit system can utilize more random-access memory (RAM) and handle larger files and datasets more efficiently.
Is 32-bit good for low end PC
64-bit programs require more memory to run than their 32-bit versions. So on older 64 bit machines, with less RAM onboard – it makes more sense to run a 32 bit OS. That situation can easily be mitigated by installing more RAM. But if you don't have that luxury – then sticking with a 32 bit OS is your best recourse.
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).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.
What is 32-bit disadvantage : However, the downside of using a 32-bit operating system is that it has limitations in terms of memory and performance. It can only access up to 4GB of RAM, which is not enough for running complex applications and programs.
