I'm talking more about pixels that polygons, but yes there are many other factors that limit practical throughput.

I haven't been able to find any links on the Tegra T20 performance. Care to share?

Thanks for the link!
Whoops, sorries. Capt'n Crunch sounds like a cereal, but it does have that nice ring to it

Do you mean theoretical maximum pixels per second?
Because that is usually blown out of proportions and is not a good indication of the device's graphic's potential. I think the max polygons/sec (aka triangles/sec) are more indicative, but even that is flawed.
Unless you mean Pixel fill rate, then I understand what you mean, but that means of measurement is also flawed.

For an analogy, its like looking at a list of cars. You have the max HP (polygons/sec), but that doesn't mean the car is faster. It usually is, but there are several other governing factors. And likewise, the pixel fillrate is like the max torque. The real indication is their real performance, eg "0-100" = "sustained polygons/sec" or even "fps in a 3D game".

It was difficult but I did manage to find some thoughts on the Tegra2 specs, and it's (theoretically) max output is below the SGX540, but in practical/real world testing it should perform slightly better than the Hummingbird chip. I will post these up when I find them again.

On another note, anyone remember the Advent Vega?

Its a pretty hi-end tablet that runs Vanilla Froyo on the Tegra2.... there's some new info/video on it.

Anyone notice that the representative said during 3:20 - 3:35, that the screen is above 720p but below 1080p. This implies 1366 x 768 (which I pray it has so I can buy it in a heartbeat).

BUT hold on a sec, wasn't the speccs leaked saying it comes with 1024 x 600?
And it makes sense for 600p because that is the maximum resolution Android supports (according to Google). With Gingerbread, Google is planning on starting their tablet revolution and one of their plans is is to increase the max resolution to 720p.

If you think this is a non-issue, I tell you it most certainly is. If the Vega has a 720p screen but that is limited by software to 600p I will be a happy chap = the community can upgrade it to Gingerbread and remove that limit. If it has a 600p screen, I will think twice about this product.
Why is this such an important difference?
With 720p available it means you can watch HD television, HD videos (think bluray/online).
It also means that you don't have to convert your HD media from 720p down to 600p (which would be a big pain in the).
And last but not least, the difference in pixel density is quite apparent (119PPI low VS 157PPI medium), and this means less "clunky" and much smoother graphics.
