Antwort Is it better to have 32-bit or 64-bit? Weitere Antworten – Is it better to choose 32 or 64-bit
Reasons to choose the 64-bit version
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).However, the only issue will be that while running a 32-bit program on the 64-bit machine is that the processor will not run to its full capacity. Also, the 32-bit program will not be able to address the whole RAM, and some resources of the machine will go to waste.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).
How much more powerful is 64-bit than 32-bit : Keep going exponentially and you eventually get 32-bit (2 to the 32nd power) worth 4,294,967,296; 64-bit (or 2 to the 64th power) is worth 18,446,744,073,709,551,616 values. That's 18.4 quintillion and change.
Will 32bit run faster on 64-bit
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.
Does 32-bit run slower than 64-bit : So for a given program it is much more likely that 64 bit is faster than 32 bit. But it varies by program.
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.
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 faster than 64 for old PC
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.Better performance when moving data.
Since processors use 64 bits for both addressing and data, the processor can carry twice the amount of data carried by 32-bit processors in every clock cycle. This enables the processor to handle far more data and instructions per unit of time than previous processors.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.
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.
Is 32-bit slower 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.
