I recently upgraded from an AXP configuration to an A64 one and although most things have gotten a big speed boost, a few programs have gotten significantly slower for some reason.
XP system: Athlon XP 3200 (200x11mhz, barton, 512k L2), Asus A7N8X, 1x Corsair VS 512mb and 2x Samsung generic 256mb (200mhz 3-3-3-8 1T)
64 system: Athlon 64 3200 (250x9mhz, some kind of 90nm, 512k L2), Asus A8V deluxe, 2x Corsair VS 512mb (208mhz 2.5-3-3-8 1T)
(everything else is either the same or doesn't affect performance)
Dosbox runs much slower than it used to. A lot of stuff that ran perfectly on the XP setup at 20000 cycles and no frameskipping now either needs under 10000 cycles or a 1x frameskip or does not work at all without heavy stuttering. This isn't a huge deal as I only start up these old dos games occasionally, but it's surprising to see such a large difference in favor of the XP. Mathematica also does a variety of numerical calculations a bit more slowly (as measured by its timing function). The differences are smaller here but still consistent across the board.
These results are quite strange considering that the 64 and its setup seems to be better in every way, including the clockspeed. The 64 is an engineering sample with an unusual label but I doubt it's all that different from retail versions since (windows) games and sandra benchmarks all work just as fast as they should. In the games there is no comparison; my framerates shot up pretty dramatically in most places even at video card intensive settings. By the way, CnQ is turned off and the windows settings (including background services) are almost identical between the two setups.
Anyone gotten similar results or can explain what is going on here?
