The 386SX is a 32 bit processor running on a 16 bit bus.
A 386SX processor has 16-bits and 386DX has 32-bits
The i7 is a 64 bit processor.
Goto start -> Run and type winmsd.exe. This will bring up system info page. If the string next to Processor is x86, its a 32 bit machine . If the string next to processor is ia64 or AMD64 then its a 64 bit machine. Source: http://support.microsoft.com/kb/827218 cheers, Esha
8086 is a 16bit processor.
The 386DX is a 32 bit processor running on a 32 bit bus.
As it is 16bit processor it can manupulate 16 bits in one operation
The iMac uses an Intel Core 2 Duo processor which is a 64 bit processor.
A 264-bit system has 64 bits.
The DS's ARM9 processor is 32 bits. This is not a direct indication of its processing power, which is why it can play '64-bit' games.
The Wii U uses a 64-bit PowerPC processor. I think that's the answer to the question you were trying to ask. I'm a bit curious why anyone who isn't a programmer or electrical engineer would care about how many bits a processor "has".
A 64bit Processor is a specific type of processing chip. In general, a processor is a micro-chip designed solely to do calculation, to be the brains of a computing system. More specifically, the "64bit" refers to the size of the data inputs, or in other words the size of each piece of information being sent to the processor as 1 step. In this case, each instruction being sent to the processor would be 64 bits, or 0's and 1's, long.
