S3 DeltaChrome S4 Graphics Chip Reviewed
EconolineCrush writes "The Tech Report has a preview of S3's budget DeltaChrome S4 graphics chip for PC graphics cards. While not the fastest option for games, the S4 looks like a credible alternative to ATI and NVIDIA's dominance of the graphics market - there are some handy analysis graphs comparing performance in Wolfenstein: Enemy Territory, Unreal Tournament 2004 and Far Cry. Better still, the S4 has component HDTV output built right into the chip, making it an intriguing option for home theater systems."
Being in the market for a new graphics card (Doom 3 anybody?) I have to admit this wouldn't even show up on the radar. I have enough concerns about ATI stability, or the fact that I need to buy a separate minitower and nuclear power supply to power the nVidia cards.
The component out is a major selling point however, for home theatre people anyway who might want to play the occasional game.
This is more interesting for being the graphics technology that will be incorporated in upcoming VIA integrated chipsets however.
I'd still get a low-end ATI or nVidia card above this however. What will S3's support be like for Linux?
I concur with this statement. Closed-source drivers are a PITA to deal with. I'd happily dump my ATI card and get an S3.. even if it was somewhat inferior in terms of performance, just so that I could not have to deal with installing yet another program every time I recompile my kernel. Plus being open source and all, a lot of performance could probably be gotten through various optimizations over time.
Normally I'd disregard this as the usual slashbot knee-jerk, but in this case opening the driver source is actually plausible.
NV and (to a lesser extent) ATI have invested a huge amount of effort in their drivers. A good GL driver was never trivial, and if anything is becoming more complicated as drivers take on responsibilities like compiling and optimizing shader code. Even without the oft-rumoured third-party IP issues, I don't see much chance of the big players releasing their source anytime soon.
S3, on the other hand, may be starting with a pretty clean slate. Their drivers are probably still pretty shaky once you step off the usual Quake rendering paths, and tightening them up could take years if they only have in-house dev resource. They're positioning this as a budget part, and are presumably very keen to keep costs down. They're an outsider at the moment and might happily grab a niche like Linux as a toehold from which to make a play for the wider market.
Fingers crossed.
