SysMark2002 is more of an extension of SysMark2001 rather then a whole new benchmark. The applications used during testing have been updated and most importantly for AMD users, the new SysMark2002 uses the Windows Media Encoder 7.1 which supports the AthlonXP's SSE instructions.

1.	AD77 Infinity - 166/333	266
2.	K7N2-L - 166/400	274
3.	K7N2-L - 175/350	295
	Office Productivity (FSB/Memory)

2.	K7N2-L - 166/400	176
3.	K7N2-L - 175/350	183

SysMark 2002 seems to favor the K7N2 quite a bit more then the KT400 based motherboard. In the Office Productivity portion of the benchmark the performance is much closer.
