Is a dual core computer useless without a 64bit OS?

Question

A computer or laptop with Core 2 Duo processors or Athlon 64 X2 Dual-Core... are they not being used to their full potential without a 64bit Operating System? Like xp 64bit or vista 64bit.

If so why?

I dont understand what the 64bit os is!!! :[

Answer 1

64bit OS is for 64bit programs which there is hardly any of. Now 32bit OS is still the better option and it does not have anything to do with your 64bit dual-core processor. :)

Answer 2

Not really, 64-bitness and duality are two separate hardware characteristic; there is a degree of thunking process in using 32-bit on a 64 CPU and that took perhaps few MHz of processing power away from a total of GHz. A famous bit change was the original Mac had to use 32-bit instead of a more comfortable progression of going 16-bit from 8 because a responsive GUI demanded it.

Similarly how Macs are 64-bit since G3 or G4. You will start to have business gain with 64 bit as it matures.

Answer 3

sure you're incorrect - optimization of the cpu works at many tiers. The computational load is chop up between 2 processors in spite of what os you run this could be an advantage no longer least of all whilst it comprises multitasking - e.g. burning dvd's no longer hogs all the equipment My known reproduction of domicile windows immediately recognises 2 processors and shifts processing load subsequently of direction in a appropriate international the apps may well be written for a dualor multicore equipment yet shall we be elementary uncooked processing velocity isn't the bottleneck in maximum circumstances The 32 bit difficulty is a various component altogether sure it means greater memory could be addressed however the computing device is bogged down because it has to handles sixty 4 bits of information quite of 32 at a time

Answer 4

yes a 64 bit processor is useless w/o a 64 bit OS, but most ppl never use a 64 bit OS casue they do not need to,most if not all ppl do not need 64 bit OS casue it has a lot of problems and requires like 3 gb or more of memory, not to metion there r not a lot of 64 bit programs. 64 bit os takes advantage of more memory. u do not need a 64 bit OS. the next version of OSX 10.5 will be all 64 bit.

Answer 5

The 64-bit systems offer direct access to more virtual and physical memory than 32-bit systems and process more data per clock cycle, enabling more scalable, higher performing computing solutions.
