Glaze3D Interview
TechZone has posted an interview
with one of the (Bit)boys behind that Glaze3D muscle-chip
that has been much talked about, but not seen yet. Hrmm...quite a
few assumptions here eh?
Q: Assuming the Voodoo4 is equal to 4 Obsidian boards running in tandem, or 8 Voodoo2 boards with a total external memory (SDRAM) of 96MB and a fill rate approaching 1000 mtexels/second, will the Glaze3D 1200 be able to compete?
A:Voodoo 2 does 90 MPIX/s, so Voodoo 4 would do 720 MPIX/s. At true color and with a 32-bit Z this would require 8.6 GB/s of memory bandwidth. This is not available without embedded DRAM and Voodoo 4 doesn’t use embedded DRAM. So Glaze3D definitely has more better performance.
