While we have seen other websites have a quick look at the performance given by the 12 to 16 pipeline mod, we have gone right through our usual benchmark suite which allows us to get a better look at where the extra pipelines will improve performance. It would be a safe bet to say that most users looking at a mid-range graphics card will consider an X800GTO which is capable of being modded to the full 16 pipes, because you're getting similar Radeon X850XT performance at around $100 US less.
For interest sakes, the Sapphire X800GTOÂ˛ Limited Edition comes clocked at the modest default reference speeds of 400MHz core and 490MHz memory. Most Radeon X850XT cards come clocked at 520MHz core and 540MHz memory. When overclocking the Sapphire card, we managed a higher memory clock speed than the default X850XT but the core overclock was about 40MHz slower.
Extra performance can be seen throughout our testing and even though the graphics card didn't want to overclock as much when we unlocked the extra pipes, it still performed faster then the pre-modded tests at higher clock speeds.
The flash only takes a few minutes but as always when it comes to modding and overclocking your components, you do have to take the warranty factor into account and think if its worth taking the risk that you could possible lose your warranty if you couldn't flash back to a default BIOS.
If you do have a Sapphire X800GTOÂ˛ Limited Edition good luck with the mod and if all goes well, we are sure you will be pleasantly surprised with the extra free performance given. You can let us know of your results by posting in our forums!
