A Rocket in the Socket: The 4.1 GHz PC From Tom's Hardware
At the start of this ambitious project, our engineers asked themselves
the question: how fast is fast? Or, how fast does a PC fitted with the
most powerful hardware have to be in order to show a clean pair of heels
to the world's best PC systems? Isn't the nondescript box of tricks
on display in your local superstore fast enough already? Well, for
most people the answer would be 'yes.'
However, nothing can stem the tide of progress, and when a PC is used
for work, having a really fast machine is a necessity rather than an
option. There are other things to consider, too. We have a
never-ending fascination with the creation of ultimate machines offering
us ever more power. Also, it is human nature to push physical
boundaries to their limits.
When we check out the current state of the art in processors, we have
Intel with its Pentium 4 running at 3.06 GHz and the AMD Athlon XP 2800+
running at 2250 MHz. Now, we all know that processor speed on its own
tells us very little and that the overall design of the CPU is critical.
But what if recognized benchmarks are involved?
In contrast to systems assembled by some of the industry's so-called
experts, who use liquid nitrogen to run a P4 just beyond 4000 MHz for
a brief moment, our system is suitable for normal day-in-day-out use.
A car engine that shows promise on the test bed is all well and good,
but maximum theoretical speed doesn't help much when you need to
overtake quickly and safely. Here, we give you a taste of what is
possible.
The 4 GHz machine achieves over 500 points with the BAPCo Sysmark 2002,
the Comanche 4 3D game runs at 75 frames per second, and Quake III at
435 frames. What else is there to say? Conventional ready-built high-end
systems deliver only about half of this performance.
The PC system we put together, thanks to compressor cooling, reached a
processor speed of 4.1 GHz. This speed was consistently maintained.
