Hi Falks,

Lately I worked on a little project where I decided to test my GeForce 6800LE card to see how many pp/vp can be unlocked and how far the card can be overclocked.
I then decided to add the Radeon X800SE to the project; it has no unlockable pipelines but it can clock very well and it's from the same generation, so it's kind of interesting.

At the end the 6800LE managed 354MHz / 730MHz w/ 12pp/6vp (from 300MHz / 350MHz w/ 8pp/4vp)
The X800SE (8pp/6vp) managed to get up to 555MHz / 1110MHz (from 425MHz / 400MHz )

Here are few tests

I kind of skipped these cards back in 2004 because I had the X800PRO VIVO with @XT BIOS-MOD, but the performance improvements are pretty interesting I think!
Will do a full compare/review at some point

Yea the Le could often become a 6800nu, I think the x800se depends on the core, they used everything that was questionable for them, what core does your have? Also fun fact the 6800le was short lived and replaced by the 6600gt so those will all be nv40 cards

my X800SE has a R420 core, with printed "SE" on it and should be like this for all the X800SE, no?

no, the x800SE could be R420 or R430, it's offically an R420, but they basically used whatever was laying around to make them.

Uhm, you sure? Can not find any info about X800SE AGP with R430, which is also a PCIe native variant, so it would have required the use of a "Rialto" bridge/chip, increasing production costs, I guess
The native PCIe version of the X800SE instead is based on R423 from what I can see
