Many HW TnL engine before the consumer revolution were actually embedded CPU(s) dedicated to the task to offload the main CPU It was common for i960, DSP or the Sony design (PS2 Vector Units). (In the Dx5/6 I remember at least one of the smaller vendor talked to us about a prototype card they were …

Mostly true there. The Spectre line was setup with a separate geometry chip (I vaguely remember Sage as the codename) with everything else on a separate chip (Rampage). The entry level line was 1 Sage and 1 Rampage and the high end was 1 Sage and 2 Rampage chips. From the benchmarks that have come …

Avenger was solid and traded blows with TNT2, made them lots of money. It was definitely the VSA fiasco that killed 3Dfx. I had V3 3000 at the time, my friend had V4 4500, there was miniscule fps difference in UT99 :o Who decided releasing another DX6 chip a year after previous DX6 chip was a good …

Designing new chips takes a lot of time and manufacturing chips takes quite a bit of time as well. The VSA-100 chip was supposed to be ready sooner than it was, it was going to compete with the GeForce 256. As far as I can tell, acquiring STB and getting into the business of selling their own cards …

I'd rather see an ISA card with a HDMI or DP out that does internal upscaling to 4k. Actually I'd like that for a PCI card too. Maybe you could even do some post processing on the image for retro visuals. Also make it so you can redefine the amount of RAM it has too for ultimate compatibility …

There will be maximum permissible performance metrics tied to the speed of the bus. Short of doing something real extreme, like making said isa card into a system-on-board or 'board based cpu upgrade card', or building it as a radical interposer or something (the latter defacto ceasing to be ISA at …

I mean there's always room for some improvement, especially decades later, but the primary bottleneck historically was the bus itself. Even designs that had little to no optimization showed massive gains moving to VLB. I doubt there's really all that much left to wring out.

The thread is very interesting. Any opinions for 3DLabs Permedia 2? Can this one qualify in the category "worst fastest early 3D cards"? I got one recently, but sill have no time to test it in windows 98/xp. Permedia 2 is really disappointing and not really even bad in interesting ways. OpenGL …

That screams memory issues. It would be odd for it go from fully functional to this sort of state just getting unseated and moved to a new system but it is almost 30 year old hardware so anything can happen.

@hard1k Thanks for the kind and funny comment :) @DrAnthony The extra TMU isn't doing anything at the moment, it will need custom drivers for that. As for the FPGA, I don't yet have enough experience to do crazy stuff with it :) @boggsman Hopefully this can be achieved with the extra TMU: SST2_TM. …

So in general you can get a good idea of the performance just by looking at reviews for the S3 Virge DX. While it was one of the most notoriously slow cards of the era for 3D, it was a solid 2D card. Additionally there was a vast build quality gap across the various vendors, where some were running …

Well there certainly were other cards that were far more common but just as slow like the ATI 3D Rage and Rage II. Chromatic Mpact! and Mpact2 are other options if you're looking for really weird stuff.

I'm not sure what 5 would be. Rage Fury Maxx or Rage XL perhaps. Apparently it's the gamecube GPU, flipper. I don't think that timeline fits though. The GameCube released in like 2001 and R100 Radeons were out in 2000. Heck, ATI didn't buy ArtX until early 2000 and they were the ones that designed …

It was pretty straightforward for me.

it may be a good idea to boost its vcore to lets say 3.6v. never tried this yet. higher core clock should help a lot. Agreed, 3.6 volts seems reasonable for that node. I know AMD ran their 350 nm K6 at 3.2 and I believe the Riva 128 was rated to 3.6 volts. Granted, different fabs varied a bit in …
