Greetings,
We just purchased a used nx9010, and after initially being woo'd by the specs, I'm starting to wonder about it's performance. It has:
Pentium 4 - 2.8ghz
1 gig (512x2) PC2700/DDR-333
Radeon IGP 345M
40 Gig HD
My main concern is Sisoft Sandra's memory bandwidth tests yield about 550-600mb/s... which is absolutely pathetic. SpeedStep doesn't seem to work AT ALL, as the CPU reports at 2.8ghz whether it's on battery or AC power.. (battery life is about 52 minutes on a new battery!). Either way, Sandra's memory bandwidth is pathetic for a 2.8ghz/DDR/400mhz bus. I've ran exhaustive tests on both AC power (from boot up) to battery.. no change.
Is something wrong or are these things really this pathetic? I've got a P3 1.4ghz HP Pavillion notebook upstairs with PC-133 memory that's absolutely crushing this P4-2.8ghz/DDR in every way, shape and form. Gotta be something wrong here, or did HP/Compaq intentionally cripple a P4 down to below Celeron 1ghz bandwidth?
