Nvidia graphics cards part 2: Clockspeed and core count

Many readers will probably know
that multiple CPU ‘cores’ came about
as a solution to throttling and temperature
issues when increasing the clockspeed of
a processor

Many More readers will
look confused and ask themselves
what these terms mean. Well (don’t
worry, because in this post I will
be explaining what the clock speed is,
and how agiaphical core is different
to a logical core (which is a processor
Core).
The main difference between
a graphics card and CPU is
that a GPU contsins many, many
more cores, sometimes hundreds or
even thousands. A CPU X86
generally only has between 2 and
twenty cores. Consumer devices
generally have even less. This
would appear to make the GPU
much more powerful, but because
it has so many cores, they all have
to run at lower dock speeds to
avoid temperature issues.
Another major difference is
that GPU’s don’t support features
such as virtual memory, which is a
highly mportant for almost all
operating systems.
Another major difference is
that the cache generally is
much smaller as it is shared
with many more cores than
on a CPU.
However, many projects exist
which aim to use the still far
superior computational power
of the GPU, such as the tesla.
However, until software snd
emory evolves and progresses further
you will still need one form of
X86 processor or similar.
Now, I keep mentioning
clock speed. In it’s simplest terms
it is a rough measure of the
speed of a processor. In scientific
terms, it is the frequency at
which the CPU is running.
It is also known as the clock
rate, because it is a measure
of how much electrical energy
is transferred from the beginning
of the CPU’s circuit to the
end in a given time. This is
a measure of raw computational
speed. However don’t be fooled into
thinking the clock speed is the
be-all-and-end-all. After all,
my old pc had a 1.9 GHz
processor, but my phone has
2.4 GHz. However, I know
that my PC was faster due
to things like cache and core
count.
I hope this has helped everyone,
and I will aim to put another
post up shortly.
