PC Paradox heeft een errug compleet interview gepost met een ventje van Bitboys (die finse Future Crew rakkers met hun gigantisch geile Glaze3D accelerator). Hier een stukje over de memory interface van de Glaze3D:
Q: Looking at the chip design: on chip texture cache (8/16k) and 9Mb of eDRAM (also in chip) and an external memory interface that supports upto 128Mb SDRAM. The extra on chip eDRAM is (possibly) similar in idea to the full speed on chip L2 cache of the Celeron and K6-III CPU's. As we all know the 128Kb full speed cache of the Celeron puts its performance up there with the P2/P3 in some apps. With such a large amount of high speed memory what can of benefits are we going to see over other architectures (not only current architectures but future designs too). (Question: Peter Male - PhDweb)A: The 9MB of embedded DRAM is just regular video memory, it's not used in a cache fashion. Current 3D-graphics chips get (max) 3 GB/s of memory bandwidth from external memory. They have a 128-bit memory interface, Glaze3D has 512-bit memory interface @ 150 MHz. This gives us over three times the memory bandiwidth, 9.6 GB/s. This naturally translates to the high pixel fillrates.
Ok, dit is dus ook waarom 4x AGP bullshit is...
