As
time progresses, the role of computers in our lives progresses
and evolves into machines that are commonly used for a host
of different tasks - companies are now creating computers
meant for digital video editing, gaming, serving, and acting
as a media center. With this so called "evolution"
of computers, components have been universally standardized
(companies such as Dell now use non-proprietary components,)
which has allowed for the component market to expand with
new vendors, as well as new chipsets.


For
a long time, Creative has been known for their dominance in
the sound card industry, their DSP (Digital Sound Processing)
is boasted by many an audiophile to be the best for a non-professional
sound card. Companies have taken up Creative as a rival in
the past before, such as Aureal, and even now, Creative has
competition in the market - such as M-Audio, Hercules, and
C-Media now present consumer sound cards that have been successful.
Today I will be reviewing Chaintech's C-Media based sound
card, the AV-515M.



The first thing that I must point out about Chaintech's AV-515M
is that it is a budget sound card. In this review, I will
be pitting it against a Creative Soundblaster Audigy Platinum.
Pricewatch shows the card retailing for $126.00 USD + shipping,
while Chaintech's AV-515M is listed for $21 USD + shipping.
That's roughly a $100 difference between the two.


However,
certain extras are included with the Audigy that boost up
the price - so I will instead disregard the Platinum features
of the Audigy and treat it as the non-platinum version, which
retails (boxed) for $80 USD. Is the $60 dollar difference
between the sound cards really worth it?

Some
of these specifications are implicitly true for the Chaintech
card (such as AC '97, Plug and Play, DirectSound, and PC 2.1
compliance.) The only feature that really stands out in the
Audigy is that it by default has a firewire compatible port
onboard.

The Chaintech card is approximately two inches smaller (lengthwise)
than the Audigy, and has a somewhat substantial section of
PCB that is unmarked, whereas the Audigy's PCB is littered
with connections and small IC's (Integrated Circuits.) Included
with Chaintech's card is Intervideo WinDVD, and a daughter
board that allows for optical input and output. Unfortunately,
I do not have the proper utilities to test optical sound input
and output, so they will not be covered in this review. Both
cards support 5.1 sound output, which will be tested with
headphones, and individual speakers.
There
are three stages of testing which each card will undergo:
1) "Real Application Testing" - Quake 3 Benchmarking
2) Audio Winbench Testing
3) Perceived Hearing - Differences that are noticeable in
the audio stream
The
system used for testing has the following specifications:
Processor: Athlon 1700+
Motherboard: Abit KR7A-Raid
Memory: 512 Mb of Crucial PC2100
Video Card: MSI Geforce4 Ti4200 with 8xAGP
Real
Application Testing - Quake 3 FPS
Quake
3 was run at 1600x1200 as to strain the CPU and video card
as much as possible, thereby dumping any remaining work onto
the sound card for audio processing.

The
low quality scores reflect the ability for both sound cards
to handle the smaller audio processing load, when compared
to the high quality settings. The AV-515M takes a large hit
during high quality testing, almost a 19 FPS difference from
the Audigy.
Audio
Winbench
Audio
Winbench is a utility created by Ziff Davis to test DirectSound
output based on cpu utilization. The following is the comparison
summary between the two sound cards:

In
every test, the Audigy once again beats out the Chaintech
for CPU usage. Yet, the Audigy doesn't clobber the AV-515M
by any means. In many of the tests there's a 2 to 5 percent
increase in CPU utilization, which I do not feel is an enormous
gain, however for extreme users, that might make a difference.
Perceived
Hearing
Finally,
there is the human ear testing. Each of the sound cards were
tested with wav, ogg, mp3, game sound reproduction, and midi.
Constant tones were used when testing midi and wav, and the
same ogg and mp3 files were used on both sound cards, ranging
from hard rock to soft jazz. I found that the Audigy produced
slightly richer tones, and that the AV-515M seemed a little
flat on the low end (bass.) However, the differences were
not significant enough for me to notice had I not been truly
exerting myself to try and find a difference.
Final
Words
The truth is, the AV-515M had an unfair disadvantage throughout
this whole review - it is aimed to be an all-purpose, cheap
solution with good sound; while the Audigy is aimed at the
higher-end spectrum of consumers. Considering the price difference
between the Audigy and the AV-515M, the AV-515M did surprisingly
well.
This
is the first AC '97 compliant card that I personally have
tested that I have found to be personally fulfilling when
taking its' price into account. For someone that doesn't need
to have the best of the best audio, or can't shell out a lot
of money for a sound card, the AV-515M might just be the card
for you.
Pros:
Cheap, Great Price to Quality (bang to buck) ratio
Cons:
Not for audiophiles, in real world gaming, can take a big
performance hit in system performance while playing a game
with high sound quality
Bottom
Line: This card is meant for the budget consumer, and
it does a great job of catering to its intended prospectors.
