Alliance 'Promotion AT24'
Diamond Stealth 2500 (PCI)
Diamond Stealth 2500 (PCI)

A Diamond Stealth videocard that is not based on an S3-chipset. Instead the Stealth 2500 is fitted with an Alliance Promotion AT24 chipset.

I have tested this card with DOS-benchmarks and it's not the fastest card out there (think S3, ARK, Tseng) and scores below average. I noticed that SVGABench doesn't render properly (just like the the Trident 9440 AGi does) and that the X-Vesa benchmark doesn't work. It starts with the first test but hangs halfway through. I haven't tested Windows performance and behavior yet, but the AT25 that is found on several Voodoo Rush cards reminds me it wasn't very good. > Read more
