 Posted: Tue Jun 01, 2010 2:12 am Post subject: SiS, the other other x86 CPU company |
 |
|
Int the Pentium Days we had several choices for 5th generation x86 CPUs
AMD
Cyrix
IDT WInchip
Intel
Nexgen
Rise
and...
SiS, they were mostly known for their chipsets but they did license the Rise core to make the SiS 55x series of CPUs
Here is a 550 running at 200MHz
and some info I wrote about them years back lol
http://www.cpushack.com/SC55x.html
I do have a few extra of these rather uncommon CPUs if people are interested

Will you offer them for sale or for trade? |

Sale or trade, less then $20 I think |
Please reserve one piece for me.
Thanks! |

Thanks for your article. I did not know that SiS obtained an x86 license, and manufactured embedded x86 SoC. The integrated design and low power were strong features, and it should have had OK performance for embedded apps.
However, your article indicates that these became available in Oct 2001, about 5-6 years after the Pentium Days. Pentium 4 was available at that time. |

Too bad they never made PGA versions available. though understandable from an economical point of view but would've been interesting to have SiS upgrade chips for, say, socket 7  |

What makes me sad is that "odd-ball" systems like this were ahead of their time. The big "IF" is how these were priced at the time. I'd LOVE to have one of these systems for an old-school "DOS box" now. But how much did these cost back in the day?
In any case, awesome find! It reminds me of MediaGX. The idea was good... but the process tech and fab capability just wasn't there to meet the performance death-march.
In an alternate universe SiS and VIA had 45nm yeild in 2005 =D Then again Intel would have had 16nm ready.

I will continue this thread.
Rise sold the mP6 design to SiS (as detailed above). SiS did nothing to improve the speed of the design but did reduce the power consumption, and then sold it off to DM&P
DM&P DID rework the design, and clocked it to a current 1GHz
The Vortex86DX runs at up to 1GHz has 32 KB L1 cache, FPU, 256 KB L2 cache and a 6-staged pipeline
The PMX-1000 runs at 1GHz and is essentially th same but adds a GPU, Audio controller, and IDE controller on board.
