Tseng Labs ET4000

Offering above average host interface throughput coupled with a moderate price, Tseng Labs' ET4000 chipset family were well regarded for their performance, and were integrated into many companies' lineups, notably with Hercules' Dynamite series, the Diamond Stealth 32 and several Speedstar cards, and on many generic boards.

Neither the ET4000AX or its succeeding family members offered an integrated RAMDAC,[2] which hampered the line's cost/performance competitiveness later on.

[3] The W32 offered improved local bus support along with further increased host interface performance, but by the time PCI Windows accelerators became commonplace, high host throughput was no longer a distinguishing feature.

Nevertheless, as a mid-priced Windows accelerator, the W32 benchmarked favorably against competing mid-range S3 and ATI chips.

The W32p model offered support for the PCI bus,[6][7] although earlier revisions of this chip (prior to Revision D) had some design problems that caused sub-optimal or problematic operation when used in PCI implementations, although VLB implementations were unaffected.
