There isn't -proof- one way or the other, there are only assumptions, specific design decisions and specific implementations. Don't forget in many cases, the closest thing to proof available usually means breaking an NDA and I'm not falling for that trick. Of course I don't know more than people with vast experience, but when you've been doing 3D hardware and software since 1985 like I have (on and off with about 50% duty cycle) you're allowed to argue a few points on Slashdot. I promise not to reply if you want the last word.
I'll answer. Textures. I'll also say sorry for biting your head off, but I've wasted far too much of my life doing graphics benchmarks in PowerPoint and I'm hypersensitive. If I had 12 Mbytes, I'd use it for a few tiles worth of frame buffer in a tile based renderer, subpixel accumulation for anti aliasing, and lots of texture _caches_, with both main texture memory and frame buffer off chip.
Blimey. Talk about quoting out of context! If you'd quoted my next 3 words, I said "PS2 did this". You're not trying to impress me with your developer credentials are you?
You haven't thought it through yet. Why don't you _quantify_ your assumptions? How many textures per polygon? Don't forget those fancy DX8 pixel shaders while you're there. How many texels are read to generate one textured pixel? Is this a classic Z buffered architecture or Tile Based? Any tricks like Hyper-Z accounted for? Where are your caches for the texture in off-chip RAM? If you haven't got the message yet, it's not to make sweeping generalisations about graphics architectures. Sigh.
emdedded RAM is used for the things that require most bandwidth, namely the frame-buffer. Textures don't need alot of bandwidth, and they are located in the slower "traditional" RAM.
Oh dear. You haven't thought that through, have you? How many texels contribute to a pixel per texture map? How many textures per polygon?
It's one thing to propose embedded memory in a paper design, and another thing entirely to get this working on silicon that sells. PS2 did this and Sony deserve much credit for delivering product. Execution is what matters in the graphics business. nVIDIA understand this. Architecturally or academically, what also matters, given the ability to execute, is elegance. Tile based rendering is an elegant idea, but it's a pig to execute it. Elegance is nothing without execution, and brute force isn't even elegant.
I propose a EULA that says the purchaser is responsible for all costs in modifying his or her console should the security chip need upgrading. Security through peer pressure. TWIANAL
Please don't say it isn't an issue, I wouldn't bother posting if I didn't think so. If, for example, I run a small business that relies on the public being able to make calls to my mobile phone number, and someone decides to send nasty text messages to that phone, your solution doesn't work for me. If I know the number of the phone calling I can't block it (can I?). So I tell the phone company. A week later the abuser gets a new SIM card for another provider and starts sending nasty messages again. Repeat several times. If the phone company could disable the phone, based upon evidence of nasty messages, I'm happy, the abuser isn't. Phones are more expensive thn SIM cards, unless the phone is stolen, No stolen phones, less chances of abuse.
Anecdotally, there are cases of people being bombarded with malicious, nasty text messages, who live in fear of their phone ringing, but they still need that phone. It's their freedom versus the abuser's privacy. There has to be a mechanism to disable a malicious caller's phone. Everyone in the UK seems to have a phone nowadays, abuse and theft of phones is a big problem. Society has gained overall, even if a few have lost the freedom to hack phones for fun. By not hacking, indirectly, you're making people's lives better. You can't have your cake and eat it.
Drill down this site via "Join Us" and "interview preparation" and you'll see such questions and an explanation of why they are asked. I get the impression that it would be _very_ $worth$ doing for some people...
We're agreeing, hoorah. There's probably a lot to learn from Hamlet, never got round to it myself, which proves your point. (I can almost hear the groans from the literary intelligensia.) Of course, if we only teach (young) people (in school) subjects they are interested in or that they feel are relevant, is that really in their best interests? I hated control theory because I thought it was all about controlling smelly chemical plants, until I realised I could build a better hi-fi with it.
FWIW I hated Shakespeare at school and I still have a strong urge to deface any copies of Thomas Hardy's the Mayor of Casterbridge I come across. The hardest thing for me with Eng Lit (as a geek) was not in accepting that I wasn't any good at it, but in no-one being willing even to teach me what I was supposed to do just to get the exam pass I needed on a monkey see monkey do basis. Nice point about Shakespeare being meant to be watched not read. I'm still worried that you're advocating not learning from history though, but if that's my misinterpretation, sorry.
The point about reading Shakespeare rather than watching a video is you aren't getting someone else's interpretation. Do you view Winnie the Pooh through Disney's eyes or did you make your own mind up reading the original? I live in Sussex and there sure aren't any gophers here.
A certain religious prophet who died 1423 years ago (type xemacs M-x calendar P I) has something to teach you, because there are folks who take what he said very seriously indeed whose actions and opinions are very important in world politics today. I'm not a believer by the way, I'm just pointing out an example of why history isn't bunk.
Called "Attack of the Cyber Pirates" it was shown last night (17th) in the UK. I thought it to be an intelligent documentary. Views from the recording industry, hardware industry (I never thought I'd cheer Intel, you live and learn), people who downloaded anything and everything, middle ground people who download stuff but also spend lots on music, people mixing their own music, some outfit using walls of computers (Shuttle SV24) to find sharing sites. If it's repeated, syndicated, whatever, try to catch it.
Are you serious? Take a look at SuSE 8.0 if you want to see a good attempt at encouraging people to use KDE. I don't use KDE btw, I use fvwm2 with minimal everything and keybindings, but I respect SuSE for trying to make a desktop distro that works out of the box for ordinary folks.
I think all these guys talking about how much Microsoft, or Nintendo or Sony is losing are repeating stuff that they've heard with no independant confirmation.
Non Disclosure Agreements. Even under NDA, there's no guarantee you're being told "the truth", but the need for both parties to do business means it must be pretty close. Also, there are companies that can take these things apart and work out to the cent what it likely costs to build. Every cent saved on a console selling 40 million units is $400k saved.

SS50 problem mentioned in my post is now solved, it wasn't anything to do with the SS50 itself (a bad memory device apparently). Thanks to the anonymous coward for suggesting the IDE prefetch tip.

I ask the obvious because, after getting an SV24 Spacewalker to run SuSE 7.3 very well, I know of an SV25 that has a weird CD ripping problem under Linux but not Windows, and an SS50 that just won't install anything (SuSE, Slackware, custom stripped down distro), but this could be because it has a 120Gbyte disk.

Yes, once in a while you can see the European origins of this distribution, like in the A4 bias for default paper sizes, but generally they're pretty good about providing "en" language users a good interface.

Mostly metric and despite what some would say, mostly European. And on good terms with our friends across the Atlantic. Sigh.
Hmm.
