Well the Doom 3 I was talking about was the Xbox version, a machine that came out in 2001 and has a GPU equivalent of GeForce 3 (or one of the GF4 models).

You are wrong about tech demos, in general tech demos actually are awesome looking while usually the actual games on the same hardware look worse. I've seen this so many times with ATI and Nvidia cards etc.

Also you can make specific arguments about this particuar Tegra tech demo, that it takes place in a tiny room with just a few character models running around. That doesn't stress hardware like your typical game does.

I believe this tech demo could be run on an Xbox or Wii.

TEGRA is some nice stuff.

However, I wonder if they will be able to implement that across a large enough group of handsets to make it viable for developers to seriously use.

The mobile market is very fragmented. Its getting better due to smartphone OSes de-balkanizing platforms into major groups (Symbian, WinMo, Android, iPhone, BlackBerry), but adding more hardware variants may cause problems for developers. Developers need to ensure their product is deployed on as many fronts as possible. So the question becomes 'can TEGRA become a factor of de-balkanization for developers, or the opposite?'.

If Tegra can unite hardware, I think it could be huge for graphics and developers. After all, if Tegra becomes very popular, you would think that dev budgets would scale to implement a title across a lot of platforms pretty easily.

You have some points but as for tech demos it's a different story.

You're right about video cards tech demos, generally they looks better than pc games on the same graphics card (I remember the ati toyshop demo for example) but that's because pc games aren't designed to run on a specific machine, the same game can be run with different CPUs and GPUs so none of those games really make out the most from your hardware.

Tengra is an endebbed platform...so its future applications will be specifically designed for it, that changes everything....look at doom3 as you said runs pretty well on xbox using a geforce3 while I wasn't able to run it at 60fps before geforce66000 on PC, also look at ps3 graphics, its gpu the RSX derived from geforce7900 architecture, I doubt you've ever seen a game looking as good as uncharted 2 running on a 7900 graphics card

Teh Tegruh iz teh future!

You're moving the goal posts a little now lol, but I agree that there are advantages to a unified platform like optimization and so on.

Uncharted 2 though, I think, got a lot of help from the Cell SPUs.

I wish we had the specs for Tegra. Or maybe they'd still be hard to interpret and compare to standalone GPUs.

I do not want to live in a world where all we have to play for video games are games on our cell phones.

lol you're right I got a little carried away....still I don't think that epic's statement is absurd considering the lap between Tegra 1st gen(quake 3 @35fps) and 2nd (demo comparable to a late gen xbox/wii game) , maybe in some time we'll see graphics on handleds comparable to HD consoles, obviously only before Ps3 and 360 succesors will come out.

A better question would be.. how many 720p handhelds does the market currently have- and what is the power consumption of tegra 2. I dont see if this will be of much use on a 2.5-3" screen. Its pretty but you wont do justice to the GPU(s), a better platform would be tablets/handhelds 4-5"+ screen size and netbooks or Ultra thin laptops.

Its interesting but the tech demo was kinda crap. We'll have to see what games it can do before we can call on this one.

in that video the guy said 3-4 years ago.... that's a really long time ago in PC terms, also, memory amount and memory speeds with vary in mobile devices since that dictates how many effects you can put into a certain resolution.

Tiga?

Wait, you said Tegra.  Sorry, carry on.
