I didn't notice any performance jump after changing T2500 to T7200, both 2GHz. In fact I didn't notice anything. Not in video encoding or anywhere else.

i moved from 2Ghz T43 to 2.2Ghz T61p and yes i saw a jump.
but really noticed it when i moved to Vista64.
when both machines run XP it's marginal difference.
but when i moved to Vista64, oh yeah i can see the difference easy.

Feeling any difference heavily depends on how you measure it. "Standard" programs won't run much faster at the same clock speed (unless the CPU's pipeline is larger). But I noticed 50% speed increase of a real-time ray tracer when tested on a Core 2 Duo at the same clock as the Core Duo it was developed on. And this was only because the much better implementation of the SSE instructions on the Core 2.
Apart from the SSE3 instruction set, the first Core Duo generation was basically two Pentium M's put together.
