Intel
Pentium 4 2.53 GHz 9/10. Date Posted 14/09/2002. by Saeed Amen.

This
is Intel's latest processor (2.8 GHz Pentium 4 is being launched as we
speak, which should result in a significant price cut for the 2.53 GHz).
The early Pentium 4's were criticised for not being powerful enough. However,
with clock speeds exceeding 2 GHz, the Pentium 4 has surely confounded
those critics. In the pictures above you can see the Intel D845GBV motherboard,
with the tiny Pentium 4 2.53 GHz at the top, which fits into the microPGA478
socket. It is made using the 0.13 micron process (so the transistors are
packed more closely). This is signifcantly smaller than the first generation
of Pentium 4s. The D845GBV board is an integrated one, featuring graphics,
sound and also 4 USB 2 ports (which can be expanded to 6). It supports
bus speeds of 400 or 533 MHz. If you prefer to bypass the integrated graphics
you can just insert an AGP card (upto 4X). However, for most purposes
the on-board graphics seemed fine. Also this motherboard supports cheaper
DDR266 SDRAM memory. It is nice to see that you can get genuine Intel
motherboards that do not need very expensive RAMBUS memory! I tested the
motherboard with 512 MB DDR266 memory and a WD 100GB 7200rpm IDE drive.
There are of course the usual standard features on the motherboard, like
support for Ultra ATA 100 drives and PS/2 connectors. However, I could
not get my Adaptec 2940U2W's bios to boot on the motherboard (although
once booted up SCSI devices were recognised).
Installation
of the processor was quite easy. On top of it, I fitted a Zalman Flower
Cooler. After carefully arranging the cables in the system, I managed
to cool the processor to a constant 45C, in a full tower case. This is
a far cry from my dual Athlon MP 1.2 GHz system which requires extra fans
to cool it to this temperature. Intel have obviously worked on reducing
the heat output from their newer processors! As such it makes a good choice
if you wish to make a quiet machine with as few fans as possible. It also
makes this processor an ideal choice for overclocking (however, I did
not attempt to try it!)
In
testing the processor seemed very quick. I mostly tested it on music and
graphics applications, which were all very processor intensive. I did
not really want to test it on office applications, because let's face
it, if you are just using Word, you can probably get away with a 500 MHz
Pentium 3! However, many people are now using their computers for heavy
graphics work and audio editting, which benefit from extra processing
power. Also nearly everybody listens to MP3s, whose encoding is very processor
intensive. Speech recognition is just catching on, and I suspect this
will be the killer app, that will sell the faster processors of the future
(as will video editing).
You
can see some of the times recorded below. I compared it with a first generation
Pentium 4 1.5 GHz (with 512 MB RAMBUS and SCSI RAID array) and my dual
Athlon MP 1.2 GHz (with 512 MB DDR RAM and WD IDE drive). Two slower Athlon
MP 1.2 GHz are cheaper than a Pentium 4 2.53 GHz, so I thought it would
be interesting to compare the two. However, dual motherboards are generally
more expensive, and you also need more cooling devices.
The
results were quite a surprise. Although all the programs I used were said
to be "optimised" for dual processor, the Pentium 4 2.53 GHz
still managed to trounce the dual Athlon 1.2 GHz on nearly every test,
except for some for some very complex filters like Radial Blur on Photoshop
and the times were similar using TimeFactory. My tests suggest that most
users would be better off with a fast single processor machine, rather
than one featuring two slower dual processors. Also many office programs
are not optimised for dual processor machines. In addition, it seemed
to make little difference that the Pentium 4 1.5 GHz was equipped with
such a fast memory and disk subsystem. As such, I believe the 2.53 GHz
is fast enough to warrant upgrading from slower and older Pentium 4 models.

The
Intel Pentium 2.53 GHz certainly seems like an impressive processor. Intel
have put behind them the early Pentium 4s, when the Athlon was beating
them in most tests. Now it seems Intel is king of the hill, but can AMD's
Athlon 2600+ fight back? One point to note, though, is that Intel's Pentium
4 range is more expensive than AMD Athlon if you want to buy a prcoessor
separately and build your own machine. As such I would recommend taking
a look at ready-made Intel based systems, as they are often far cheaper,
and then modifying them to your requirements.
