Diamond Multimedia's Stealth S80
A legend returns to the graphics market

By Robert Maloney
February 15th,  2003

Many seasoned PC enthusiasts fondly recall being the first on the block to have a high-powered Diamond Viper card in their rig, and boasting about it to their friends.  Back then, Diamond and performance were nearly synonymous in the computer world.  It was a big loss when they pulled back in 2001, only offering their Supra line of Modems and Rio MP3 players.  After a three-year absence, however, Diamond has returned, starting off a bit slowly with their new value-minded Stealth line of cards which will soon be followed up by a high-powered Viper line.

Upon hearing of Diamond's resurrection, we had high-hopes for a unique product line.  The only way to stand out from the crowd is to offer something distinctive, whether it be the software bundle, the cooling method, or some other feature such as Tyan's TGM technology.  What will Diamond, or better yet, Best Data bring to the market that will make them a front-runner once again?  See, this is Diamond in name only.  Best Data purchased the rights to Diamond's brand names and trademarks, and is using the Diamond name to make a bigger push into the graphics market.  The big question is then, can Diamond / Best Data re-capture the hearts and wallets of an already jaded buyer's market?  That remains to be seen.  Our reintroduction to Diamond begins with the Stealth S80 - a feisty little card powered by ATi's Radeon 9200SE VPU.

The bundle is just what one would expect, considering the main-selling point of the Stealth S80 is its price.  There's two CDs in the package, one that contained an interesting mix of drivers, software, and benchmarks.  The other CD is a full version of Spy Hunter, a remake of the classic arcade game which should perform well on the Stealth S80.  In what is surely a cost cutting move, what you won't find in the box is a user's manual.  The only paperwork was a quick installation guide, the warranty and registration information, and a voucher for two free issues of PC Gamer.  Diamond also threw in an S-Video cable for connecting your PC to a TV.

Closer Inspection of the Stealth S80
Stealth technology revealed

The Stealth S80 is a lean, clean, graphics machine devoid of large heatsinks and using a relatively uncluttered PCB.  Backed by an ATi-typical red PCB, there are no distinguishing markings save for the 'D' logo on the fact of the card.  In fact, a sticker on the back of the card identified the card simply as an "ATi Radeon 9200SE".  The ram consisted of 5ns TSOP memory chips that Diamond has clocked at 180MHz.  Other than the VPU, RAM, and three small capacitors, the card is remarkably clean front and back.  External connections are the standard fare, with VGA, S-Video, and DVI ports allowing connections to both analog and digital monitors, as well as TV-sets.  It probably comes as no real surprise that the card does not require any additional power connections as well, allowing for easier installation when upgrading.

         

A slim, passive heatsink is seated over the VPU, which should handle the load easily as the core speed is only humming along at a mere 200MHz.  Removal of the heatsink consisted of releasing the two spring-loaded clips, where we found an abundance of a runny thermal paste.  We cleaned this up a bit, grabbed a camera shot of a now visible 9200SE core, and re-attached the heatsink.  An obvious benefit to the passive cooling method is that it doesn't add any additional noise to a system.  So, if 3D applications are not a primary necessity, adding in a Stealth S80 is not only a frugal option, but a silent one as well.

Some Stealthy Screenshots
Now try saying that three times really fast
Since a retail version of Spy Hunter came with the Stealth S80, we decided to take a couple of screenshots of the game to show off the card's capabilities.  The super-sleek car from our childhood now sports some new capabilities such as transforming into a boat or motorcycle.  We then took a few screen captures of the same starting scene, with and without anti-aliasing and applying anisotropic filtering.

As you can see, the card can generate some nice visuals, but we recommend using some lower resolutions in order to keep the frame rates at a playable level.  Spy Hunter is a DirectX 8.1 based game, which caters to the Radeon 9200SE's strengths, but even at resolutions over 1024x768 we began to see some slowdowns.  Needless to say, the Stealth S80 will probably not fare too well with the current and future crop of DX9 titles.  We were able to move smoothly along in Spy Hunter, even when applying 2X AA, and then again with 4X anisotropic filtering enabled.  The optimizations really clean the images up a bit, as you can see by checking the above images side by side.  At 2XAA with aniso enabled, the edges of the car are much smoother and objects in the distance, such as the numbers on the wall, are much sharper.

The Test System and our first benchmarks

Benchmarks With Unreal Tournament 2003
DX8 Performance In The Mainstream

Epic's Unreal Tournament 2003 has consistently been one of the more popular shooters, and by no coincidence is it also one of the most used benchmarks for video card testing.  There are many variants to testing the game, one of which is to use a "Flyby", which plays back a recorded tour of one of the levels.  Here in the labs, we use a custom INI file that maximizes the graphical settings, and then displays the average frame rate.  We chose to run the tests at 1024x768x32 and 1280x1024x32 scores for our report, with and without 2X anti-aliasing enabled. 

There's really no comparison between the two cards in the Unreal 2003 benchmark.  On the whole, the Stealth S80 put up some painfully slow scores, usually about half of what we got with the GeForce FX 5200 Ultra.  To its merit, the performance hit when applying two samples of AA was minor, especially when compared to the competition.  We still wouldn't recommend it, however, since it seems we will need all of the frames we can get to maintain "playable" conditions.

Head-to-Head Performance With Splinter Cell
Stealth Pixel Shading Redefined

Splinter Cell's version 1.2 patch includes three demos in addition to a benchmarking feature.  We used the Oil Rig demo created by the folks at Beyond 3D to benchmark with Splinter Cell.  This demo removes two CPU intensive routines while increasing dependence on Pixel Shader performance.  Shaders are used to render the realistic looking ocean water surrounding the Oil Rig, as well as simulating a night vision display.  As we've mentioned in the past, anti-aliasing doesn't work with Splinter cell (at least with the current version).  Due to this fact, as well as the obvious reasons, we do not have any AA scores listed in the graphs below.

 

These two graphs told us two things: one, the Stealth S80 lost out to the 5200 Ultra at both resolutions, and two, we can say with utmost certainty that neither card should be used to play this game.  We barely were able to get over ten frames per second at 1024x768 with the 5200 Ultra.  Worse, the Stealth S80 was hovering closer to five fps.  Oddly enough, when actually watching the demo, the performance didn't seem as bad as the numbers actually were, but you can be sure we're not going to try playing this game with these cards anytime soon.

Performances Comparisons With Novalogic's Comanche 4
The Performance Battlefield

Novalogic's Comanche 4 Demo is probably the oldest of the tests in our current suite of benchmarks.  This benchmark uses DX8 class pixel and vertex shaders to produce some of the realistic visuals used throughout the demo.  Unlike the previous tests, this benchmark is heavily influenced by CPU and system memory performance, especially at lower resolutions.  Usually, when the resolution is raised and AA and Anisotropic filtering are enabled, the performance of most video cards tends to slow down quite a bit, however, we won't need to do so here with these two samples. 

At 1024x768, we find that the 5200 Ultra is putting up a respectable 41.71 frames per second.  Nothing to write home about, but not too far off the mark with some of the more powerful video cards we've tested.  The Stealth S80 could only muster up just shy of 24 fames - which is one of the lowest scores we have seen in this benchmark without AA applied.

Benchmarks / Comparison With Wolfenstein: Enemy Territory
New Game, Better Effects, Old Engine

We also ran through a batch of timedemos with the OpenGL game Wolfenstein: Enemy Territory.  Wolfenstein: ET is a free, standalone multiplayer game that is based on the original Return to Castle Wolfenstein, which was released a few years back. It uses a modified Quake3 engine yet exhibits plenty of CPU scaling and platform variation, which also makes it a good benchmarking tool.  We created a custom demo and used the built-in timedemo feature to check each card's frame rate.  The tests below were run at 1024x768 and 1280x1024, with and without 2 samples of anti-aliasing.

As we've seen in past reviews, Wolfenstein just seems to run better on GeForce powered cards, but in these two tests the 5200 Ultra outpaced the Diamond Stealth S80 by 200-300%.  In a battle of value-minded cards, we really would have to give the edge to the 5200 Ultra over a 9200SE based on these results. The best thing we can say here is that we saw a minimal loss of performance with the 9200SE, usually a single frame or less per second, when using 2XAA.   

Overclocking & The Conclusion

Overclocking the Diamond Stealth S80
You can't get something for nothing

Well, after seeing the relatively poor performance in these benchmarks, we hoped to squeeze out just a bit more performance by overclocking the card.  We started by raising the memory clock speeds using the latest version of PowerStrip.  Although we had expected to raise the speed to at least 200MHz before running into any issues (5ns memory rating should allow for speeds up to 200MHz) we were not able to add more than 1MHz before getting massive artifacting in any of our benchmarks.  Switching gears, we set the memory back to its default speed and raised only the VPU core speed instead.  It was a "no-go" here as well, since it appears that this is another clock-locked card.  Using PowerStrip, we raised the core speed from 200MHz all the way to the max setting available (255MHz) with no discernible difference in the benchmarks.  We didn't get any crashes or lock-ups, but we didn't get any increased performance either.  Thus, we could not get any benefits from overclocking the Diamond Stealth S80 whatsoever.

 

Our final thoughts about the Stealth S80 are that you get what you pay for.  It's not for lack of Diamond's manufacturing or expertise that the Stealth S80 suffered so - if anything, it simply fails because of the chipset that it was created on, that being the ATi Radeon 9200SE.  The 9200SE is the lowest rung on ATi's graphics ladder, and doesn't hold up well against the competition (incidentally, Diamond also offers the Stealth S90, which is based on the 5200 Ultra and only sells for about $10 more.)  Serious gamers will probably look elsewhere, but system builders looking for an inexpensive means for providing basic Windows acceleration and occasional gaming will have no issue with laying out $49 for the Diamond Stealth S80.  We do expect for Diamond to show it's real brilliance with the upcoming Viper line of cards, based on more powerful GPUs, and will hopefully have more information on them in the future.  As for the Stealth S80, we're giving it a 7 on the HotHardware Heat Meter...
