If anyone hears anything can they post a link or say what they have heard?
I'm very keen.

damn, read the latest article there.. only 16 pipes and only around the
speed of the 7800. I was holdling off to see if this card really packed a
punch but now I'm not sure it will be worth the upgrade from my current x800
pro 500/500.
I know that the 7800 is a mighty powerful card and all but when the next
after this (ie. the R560 is only 6-8months away it seems like it might be
worth holding out. Particularly as there are no new games on the horizon
that make an upgrade a must-do. (think doom3).
maybe quake 4?

could you expect a lot more performance out of a 24 pipe r520 as apposed to
a 16 pipe? fairly noticable?

50% in theory, and if all other things were the same.

Number of pipelines does not matter as much as before. Many games are now
either shader processing-limited or memory bandwidth-limited. Look at the
7800GT: 20 pipes instead of 24 but almost as fast as the 7800GTX. RAM and
interface technology haven't advanced at all since the Geforce6 - still
256-bit GDDR3 at just over 1 GHz, and this is not gonna change in the next
four months.
Quake 4 is based on the same engine, right? How fast is your X800 Pro in
Doom3? Quake 4 will probably run at decent clip if you turn off AA.

There are no hard-wired "pipelines" per-se, actually. It's just a way for
consumers to estimate the card's fillrate now.
Look at the difference between the Geforce4 and XBox GPU: same number of
"pipelines", but the XBox has an extra vertex shader. Look at all the people
unlocking their 6800 vanilla cards to 6800GT spec, often they are successful
in enabling all four extra "pipelines", but not all two extra vertex
shaders.
To put it another way, just because the R520 has 16 "pipelines", does not
mean its shader performance is automatically 2/3 as fast as a 7800GTX at
equal clock speeds.
Anyway, none of this talk is worth a salt until the cards are benchmarked in
real games. For all we know the R520 could be as big a flop as the FX5800.

There are in PC GPUs. There aren't in the XBox 360 GPU.
We don't know it has 16 pipelines.
Indeed not. It depend on the power of each pipeline.
