DirectX 9 for SiS

DailyTech previously reported on SiS’ 2006, 2007 core logic roadmap. The previous roadmap outlined plans for upcoming SIS 671/671FX and 771 chipsets for Intel and AMD processor architectures. Both chipsets feature an integrated SiS Mirage 3 graphics core with DirectX 9 compatibility and expected to launch this quarter. A new SiS roadmap reveals greater details of the upcoming integrated graphics core.

The usual DirectX 9 and OpenGL 1.5 3D APIs are supported with the Mirage 3 graphics core. There will only be support for Pixel Shader 2.0 instead of Pixel Shader 3.0 supported by Intel’s upcoming Graphics Media Accelerator X3000, ATI’s Radeon Xpress 1250 and NVIDIA’s GeForce 6100 series. Up to 16 texture units are available though. No vertex shader is present on the Mirage 3 graphics core disappointingly. Nevertheless the Mirage 3 graphics core has an integrated transform and lighting engine which is quite common nowadays. The graphics engine clock is expected around 250 MHz.

While the graphics core won’t exactly keep up with the latest value graphics cards from ATI or NVIDIA it does have plenty of video processing features. Notable video features include pixel scaling capabilities up to 1920x1200 pixels via a 6x4 scaling algorithm and motion adaptive deinterlacing algorithms. The SiS Mirage 3 also features smoothing algorithms that smooth out jagged edges and lines in videos. 3:2 pull down detection is also supported for progressive MPEG2 video playback.

The SiS Mirage 3 graphics core is expected to enter mass production in SiS 671, 671FX and 771 chipsets this month. Expect motherboards feature the chipset to arrive in the upcoming months with prices below $100. SiS Mirage 3 graphics powered chipsets will support Microsoft’s upcoming Windows Vista with aero glass user interface.

Why?

Does this any compete with NV and ATI current on board video. Add in the the pricing is higher NV6150 and ATI express MB. Why would anyone want this?

I -think- that the article was meant to imply that you could find this chipset on a motherboard, with the entire thing costing under 100. I think you pay a bit more for the better ATI and Nvidia integrated chips (like the 6100, etc). I may be wrong though, the market may have changed in the past month...

The Asus A8N-VM CSM (Socket 939) has integrated nVidia 6150 graphics and has been selling for $80 at Newegg since at least April.

eh... is this really supposed to perform better than the intel equivalent at the same price?

Forget gaming (for intel or Sis), but even with video processing, you would think that someone doing enough work with video to care about that kind of processing would rely on more than their econo-onboard. Oh well, any competition is welcome - I guess its healthy.

sadly, id rather have the new intel integrated. whats the point? who buys this when nvidia and ati have integrated just as cheap?

and really, why even bring out a new chipset now thats not dx10, very short sighted.

The "why" is if they can offer a complete integrated solution at a lower cost. You and I may not want it, but some people will spend least possible and gripe about it later.


meh, SiS

Both ATI and nVidia have very nice budget-minded IGP chipsets with far better driver support. Why would I chose SiS over either one, regardless of the specs? SiS hasn't exactly rocked anyone's world when it comes to graphics technology. I guess it will find its way into some products here and there, but I think OEMs have developed quite the affinity for NV and ATI when it comes to the K8 platform. It's worth the extra $5-10 to say "Graphics by ATI/nVidia" when trying to sell a bre-built machine.

It's Integrated Graphics

and so, the only question should be- does it also support a PCI-e slot?
Either you don't need better graphics, or you will upgrade later. Nobody runs games beyond Solitare on these.

The 771 chipset supports a PCI-e x16 slot- I didn't find anything about the 671 versions.

I didn't claim that IGPs should be great gamers. Integrated graphics are cheap no matter who you go with, meaning that driver support should be a deciding factor. If you think 2D is easy to support, remember how Kyro GPUs couldn't draw the translucent selection rectangle in WinXP? I'm sure it had enough power, but the drivers never worked for it (the companies buyout/death didn't help much). Also, there are a few accelerated apps that offices use. Google Earth can be a useful tool where I work, and it crawls on Intel XG2, but runs just great on Intel's GMA+, ATI's X200, or nVidia's 6100/6150. Lastly, Vista has an accelerated GUI, and even ATI and nVidia are having issues making their early drivers. Oh, and many of Vista's new desktop games are accelerated as well.

Where is the vertex shader?!
