Intel Pentium 4 1.7 GHz Processor Review
who jumped on the Pentium 4 bandwagon early got stuck using the Socket 423
form factor and probably have a CPU that is sub 1.5 GHz. Socket
423 users have little options open to them for getting more 'horse power' under their hood. With
an obsolete formfactor socket 423 owners have virtually been left out in the cold with
no where to go. Even though moving from 1.5GHz to the Pentium 4 1.7 GHz it's
not much of an upgrade in terms of raw MHz, this is a decent
performing chip and is the best value CPU of the Socket 423 based P4's.
under $300 CDN you can pick up a Pentium 4 1.7 GHz CPU, and considering
that the 1.8 GHz version is $70 CDN more, the performance difference is
negligible. As we all know, with the introduction of the Pentium 4 Intel has
done many radical things with the core. Most notably is the pipeline extension.
The P4 has a 20 stage pipeline which is double what the Pentium 3 had. This was
done because with a 20 stage pipeline, clock speed could be pushed much further.
However, the penalty for this is that far less work is done per clock cycle. In
a sense, they've sacrificed work for clock speed. While generally we don't
believe in lowering the workload of a CPU to get more raw MHz, the P4 has
As you can
see, the Socket 423 Pentium 4 is huge. Covering the P4 die is a large heat
spreader which protects the core from damage and is a great idea even though in
general Intel doesn't have the same problem as AMD does with their weak cores. It's
nice to see a company take the extra step in protecting their products. Another
handy feature the P4 has built into the core is a Thermal throttling feature.
When it was first discovered, there was quite an uproar, however after the dust
settled and people came to their senses everyone pretty much agreed that it's a
good feature. After all, if the CPU is overheating, why not slow it down so it
doesn't burn out?
Since all Socket 423 Pentium 4's are based on the
Williamette core, we weren't too
enthusiastic about the overclockability of the CPU and we were pretty much on
the ball here. We were only able to garner a 187 MHz overclock out of
the chip which brought the total speed of the CPU to 1.89 GHz. Not the best
overclock, but then again it's free so we shouldn't complain. The chip was manufactured in Costa
Rica and the S-Code is SL57W.

SYSmark2001 uses real world applications
concurrently as an accurate way to test the system by following patterns that
reflect the way real users work. SYSmark2001's workloads accurately represent
today's updated business usage model. The benchmark runs at a realistic
execution speed, with think times between application interactions, in order to
emulate a desktop user's interaction with the operating system and applications.
Higher numbers denote better performance.
It looks like the P4 1.7 GHz can hold it's own in
the Internet Content portion of SysMark2001 pretty well, those scores are about
what I would expect however Office productivity is just horrible. Even when the
processor is overclocked, the performance isn't that
Content Creation Winstone
2001 keeps multiple applications open at once and switches among those
applications. Content Creation Winstone 2001's activities focus on what we call
"hot spots," periods of activity that make your PC really work--the times where
you're likely to see an hourglass or a progress bar.
Business Winstone is a
system-level, application-based benchmark that measures a PC's overall
performance when running today's Windows-based 32-bit applications on Windows 98
ME, Windows NT 4.0 (SP6 or later), Windows 2000, Windows Me, or Windows XP which
runs real applications through a series of scripted activities and uses the time
a PC takes to complete those activities to produce its performance
The P4 doesn't fair too well here in these
benchmarks then again none of the software used in either Winstone's take
advantage of SSE2 which would really boost performance if code was written for
