During the last few
years, the growth of the add-in video card market
has been phenomenal.
The chipsets powering these boards have
been flying off production lines at a dizzying
company, nVidia, has consistently cranked out
chips more powerful than the last.
Traditionally with this increase in power,
comes an increase in price.
Not so with the GeForce 2 MX that powers
the Abit Siluro MX we?re looking at today.
themselves in a dominant position when one of
their main competitors missed a product cycle.
They?re high-end chipset sat alone at the
top of all the benchmarks?so, why not make an
entry-level chip and see how we fare in the budget
must have been the thought on nVidia?s mind when
contemplating the GeForce 2 MX.
To put things in very simple terms, nVidia
took their powerful GeForce 2 GTS chip, removed 2
pixel pipelines, lowered the clockspeed and
installed standard SDRAM, resulting in a fairly
powerful, relatively inexpensive product.

motherboards, saw the potential in the booming
add-in market, decided to venture into it and the
Siluro line of video boards was born.

collaborate on an entry-level product?

specifications of the Abit Siluro MX read like
virtually all other MX reference designs?which
is not necessarily a bad thing!
The only real drawback of these MX boards
is the use of standard SDRAM.
Obviously to keep the prices low (you can
find many MX boards for around $100) manufacturers
such as Abit must use cheap SDRAM on their boards. Our Abit Siluro MX came equipped with 6Ns Hyundai RAM clocked
at a default speed of 166MHz.
Voodoo3 owners should recognize the Hyundai name
and remember the high degree of overclockability
that it offered.
Unfortunately, standard SDRAM,
clock-for-clock offers only half of the bandwidth
of DDR SDRAM, widely used with the GeForce and
GeForce 2 GTS line of cards. This results in lower performance at higher resolutions when
compared with the older GeForce 1s, even though
the MX has a higher theoretical peak fillrate.
