a quick search on our hype evaluation machine also known as the Google reveals
just shy of 9 million hits about 64-bit
versus 32-bit processors uh no some of this hype was
started by the PC crowd back when AMD launched their first desktop PC 64-bit
CPU back in 2003 but since last Fall's
launch of the iPhone 5S the first smartphone with a 64-bit CPU it's become
a hot time topic again but what does it actually mean for Average Joe let's
start with what a bit is very briefly here one bit is a single character and
binary either one or zero so it can only
express up to two values with two bits we can express up to four values and
with three bits that goes up to eight every bit we add increases the number of
different values we can represent in binary exponentially now you'll hear
about bits in relation to all kinds of computer things from data storage to
data transmission to data processing so that brings us back to CPUs in the
context of a processor the number of bits generally refers to the amount of
memory it can address so while a 32-bit processor is without pae magic tricks
limited to about 4 gigs of memory or RAM a 64bit processor can handle up to 16
billion gab of
RAM all right lonus that sounds interesting more RAM is good for
performance right bring on the bit where's my 128bit well hold on a second
there cool your rainbows My Pony friend more RAM is only beneficial if you need
it to store data that's applicable to the task your processor is working on at
a given time adding more RAM to this
isn't going to make the ball move faster so a move to more bits for processors is
not something to be undertaken for no reason aside from the hardware
re-engineering and instruction set architecture extension or redesign
it involves a complete rewrite of fundamental parts of the operating
system be it Windows OS 10 Linux Android iOS or whatever it requires specific
driver software for all Hardware components that will be used and finally
application developers will need to at least recompile and debug their code
just to achieve basic compatibility without taking advantage of any
performance improvements well okay lonus but um I really want that shiny new ooh
64-bit processor maybe the entire hardware and software Industries will
cooperate for a fast migration for the first time ever so I can have huge
performance gains right anyone I
wouldn't hold your breath here we are over 10 years after the release of the
Athlon 64 and in addition to most of the
applications on my 64-bit PC anyway running in 32-bit mode Microsoft is
still supporting entirely 32-bit versions of even their latest Windows
8.1 OS and furthermore if you think a 64-bit processor is faster then I'm
afraid you've bought into the hype my friends for certain workloads and
nothing you're doing on your phone at the moment there will be a benefit but
in most cases what you're actually benefiting from is that a 64-bit CPU
will tend to have a newer more robust design overall with more registers
functional units memory bandwidth and all that other stuff so until we need
more than 4 gigs of RAM for our phone applications which who knows may not
actually be that far away the 64 bit is
just a necessary transition being
packaged up for the general consumer as a selling point speaking of selling
