Anand Tours ATI and NVIDIA
logicalstack writes "The folks over at AnandTech have written an
expose on their visits
to both ATI and NVIDIA. Interestingly enough ATI's facility shrouded in secrecy and NVIDIA's is quite open, Including full color pictures of their server farm, and a pic of the NV30 test machine the 'Ikos.' The CEO even showed off the old school NV1 with 1MB of ram!"
Try reading the article:
ATI imposed very strict restrictions on photographs during our visit to their offices in Thornhill, Ontario; we saw a lot of interesting things at ATI's offices (including the foundation for their fountain of fire in the lobby of their main building) but we weren't able to take pictures of most of them. On the other hand, ATI sat us down with one of their chip architects and we were able to get a wealth of information about how their GPUs were made.
NVIDIA wasn't able to set us up with any engineers for an extended period of time (although lunch with Chief Scientist, David Kirk is always informative) but they were much more lax on the picture front so we were able to bring you more of the behind the scenes from NVIDIA.
ATI just didn't want anybody taking pictures, but they were the one sharing the real information.
Never underestimate the bandwidth of a 747 filled with CD-ROMs.
Hear hear! I refuse to use Nvidia based on that fact. I have an ATI Radeon 7200. It may not be as fast, nor may it be quite as good, but at least I'm not putting proprietary software on my machine when there is an alternative.
ATI was the company that provided the in depth talk with a chip engineer. With NVIDIA, Andtech had to settle to having lunch with their lead architect. NVIDIA was okay with pictures, but ATI was the one that provided real information.

Well, I suppose we could go over the reasons for the billionth time on /., but there's no reason to believe that you'll listen this time either.
Oh well. Here it goes anyway.
The primary reason is that they cannot. They do not own all of the code that is in the drivers. There are extensive cross-licensing agreements between nVidia and SGI, dating back to the creation of nVidia from a bunch of ex-SGI engineers and the ensuing lawsuits. A good bit of the core code in nVidia drivers is essentially owned by SGI. nVidia cannot release that code. Period. End of story.
The secondary reason is that there is reason to believe that there are trade secrets in the drivers. Why do most people still favor nVidia over ATI? Because of the drivers. They work damn well most of the time, and the drivers you download today still support the original TNT. Additionally look at the GeForce4 and the Radeon 8500. On paper the Radeon 8500 was superior, and yet the GF4 beat it in benchmarks consistently. Why? The drivers. They were more mature, better written, and streamlined.
Don't like the situation? Fine, don't buy an nVidia card. What? Nobody else has 3d acceleration worth a crap? All the other drivers are just as unstable and slower too? Well, gee, maybe there's more proof that nVidia knows what the hell it's doing. Yes, it sucks if you're a *BSD fan or something else such that the binary-only drivers aren't usable, but, again, nobody made you buy nVidia.
Frankly, nVidia has spectacular Linux support. They release the Linux drivers within weeks of the Windows drivers and they're pretty damn stable (frankly, I suspect that if you have continual issues here that it's some other piece of hardware being marginal and pushed over the limit by running the card at full functionality). Oh yeah, and they're fully functional... don't forget that little bit.
It's really sad to see people whining for Linux support, getting pretty damn spectacular support, and then whining that it's not good enough. No wonder most manufacturers don't bother - damned if you do, damned if you don't. So why spend the time and money on a marginal market if you're just going to get roasted anyway?
> (and buggy) Linux drivers?
You might want to try switching from nvagp to agpgart, or vice versa, depending on your mobo.
I went from agpgart->nvagp a few months ago, and suddenly most of my stability problems with the drivers were gone.
Hear hear! And why walk with *two* legs when we clearly only need one!
I don't get it. I'm all for Open Source, but I'm even *more* for a company taking an active interest in supporting their hardware under Linux. I've got a GEForce2 on my system and the drivers are *sweet*. Full support of *all* the hardwares features. How often do you get that under Linux? Not to mention the fact that the drivers compare nicely with their Windows counterparts.
Why spend the same amount of money for hardware that has less support and will effectively run slower because of it? I just don't get it...
If every hardware company were like NVidia we would have far less trouble buying a new printer/modem/videocard/etc.
