as my title states, whats the difference? any details would help.

sorry for my noob question.

All they did was practice here low-k tech on a high end part basically, after successfully implementing it on the .13 9600XT they moved it to there .15 Radeon 9800XT. Now they have .13 and low-k on a high-end part , the X800 and X800XT. The 9800XT had a few other minor tweaks.... like a temperature diode and hence overdrive in their drivers.

The .13 and .15 refer to the process. Average transistor size is 130 billioniths of a meter for .13. This move from .15 to .13 is called a die-shrink, mostly helping for more MHz. You can see they nailed down both .13 (the 96XX line) and low-k twice (9600XT and 9800XT) before bringing both to there high end product. There are growing pains involved in these things, they got it straight FIRST.

wow thanks for the info. it's really in depth.

i have a powercolor 9800se (256-bit) and i softmodded it to 9800pro. what are the chances the core is a r360. and would an r350 still be able to be flashed to XT bios? of course i will buy a vga silencer and maybe ramsinks if i do flash it.

No, you cannot use a XT BIOS on a R350 core based board. There is more than just die optimization in the R360, the chip itself contains optimizations for pixel + vertex shading that are not in the R350. Flashing the BIOS _will_ cause image corruption in Dx9 games. I have experienced this first hand, owning both a R350 and a R360 based 9800 PRO.

The optimizations are only worth about 200-300 3DMarks.. so don't sweat it.
