11 NVIDIA Forceware 81.26 Beta: Single Core vs Dual Core

This new set of drivers, the 81.26 Beta Forware drivers, is the first set we see of the upcoming Forceware which will feature many new features such as individual card clocking in SLI mode and Dual Core CPU optimizations. Therefore we decided to really pit a single core CPU against a dual core CPU on this set of drivers.

Just a few days ago, a set of NVIDIA Forceware drivers were leaked on the internet.
Now this is nothing new really, leaks of drivers are occuring so often it is
nothing extraordinary. However, this new set of drivers, the 81.26
Beta Forware drivers
, is the first set we see of the upcoming Forceware
which will feature many new features such as individual card clocking in SLI
mode and Dual Core CPU optimizations. Well the individual card clocking did
not make it into this set of drivers apparently… but rumors are afloat that
they do incorporate dual core optimizations which make use of the extra core
of a dual core AMDX2 or a dual core Intel Pentium D to enhance performance.

This is very interesting and we decided to really pit a single core CPU against
a dual core CPU on this set of drivers.

First off, we need as little varaibles as possible when we are simply comparing
a dual core vs a single core on this set of drivers.

Unfortunately, we cannot turn off the extra core on a dual core
to make it a single core. Therefore we need a single core CPU similar to the
dual core CPU in terms of every other aspects except the absence of the extra
core. That means same FSB, cache and memory speeds. The best would be a Pentium
4 540 against a Pentium Extreme Edition 840. Same Clockspeed (3.20Ghz), Same
FSB, Same Memory Speed, Same 1MB of cache (1MB on each core of the 840). However,
we did not have a Pentium 4 540 but we went on to use a Pentium 4 530. The 530
runs at 3.0Ghz. So we made the Pentium Extreme Edition run at 3.0Ghz as well,
by simply lowering the multiplier from 16x to 15x. So now we get the same clockspeed,
same FSB, same Memory speed and same 1MB of cache. The only difference is that
the 530 is single core while 840 is dual core.
