Core and memory speed is the main difference. The more expensive cards
usually have better cooling; heatsink and memory.

FX 5950 Ultra: Core 475/Memory 950 (the core is different for this one)
FX 5900 Ultra: 450/850
FX 5900 ------: 400/850
FX 5900 SE---: 400/700
FX 5900 XT---: 400/700

Some manufacture's cards are more overclockable than others. Try to find out
what memory speed and brand the card is using because some brands are
capable of higher speeds despite their speed rating.

In theory, here are the limits for memory:

2.0ns 1000MHz DDR
2.2ns 909MHz
2.5ns 800MHz
2.8ns 714MHz

A 5900SE with 2.5ns ram could probably be overclocked to 5900 Ultra levels
with some good cooling.

Some XTs run at 450/780, e.g. Gainward FX Powerpack
Golden Sample for $200. These are way cheaper than the
5950 Ultras yet almost as fast. Possibly best bang for the
buck, I think. I have one of these along side a Leadtek
5900XT and it runs 10% faster on all benchmarks.

So, architecture and features are all the same?
excellent, thanks

5900XT: 5900 card with clock slowed down.

5900 Ultra: 5900 with clock sped up

5950 Ultra: 5900 Ultra sped up further and with 256MB of
RAM

Interesting. I assume both cards were run at their respective
max OC, right? Also, what did each OC to?

No, the 10% diff is at stock speeds. Leadtek is at 390/700,
while Gainward is at 450/780. The Leadtek will overclock
somewhat, but runs too hot for my taste. The Gainward
does not have temp monitoring, so I have not tried it above
stock speed.

So all you have told us is that a Gainward at 450/780 is 10% faster than
a Leadtech at 390/700. Since these speeds are lower than
they can actually run, this comparison is meaningless.
Only a "full speed vs full speed" comparison is of interest.

Which ones have temp monitoring.

Hardly. The speeds above do not void warranties, and are both
guaranteed by the respective manufacturers. Gainward has done
significant screening of the chips to find the ones that run faster
and cooler, and you pay only a small extra amount to benefit
from this. I think most people, including the OP, would want to
know this. 95% of people never overclock their video cards.

The Leadtek has temp monitoring. Don't know of any
others that do.

Nor does any speed, but that's irrelevant to the thread.

I wasn't talking about "95% of the people",
I was talking about you. Your attempt to deceive people
with your "apples to oranges" bogus comparison would have gone
undetected because you convieniently left
out the part about clocking one higher than the other. Nice try,
too bad it didn't work.
If you are going to compare two cards,
at least test both at full speed.
