XviD processing times P4 2.4/2.8 HT 3.2/3.4 ???

[Stonechatz]

My P4 2.4GHz + 1Gb memory can process a 2 hour movie from DV type 1 (25Gb file-size), into a 703Mb CD-ready XviD (Koepi's Codec) in a time between 6.5 to 8 hours. My P4 2.8 + 512Mb mem can do the same job in roughly 5.5 to 6.5 hours (both using VDub 1.6). What lessening in the processing time could I expect from upgrading to a hyper-threading chip, 3, or 3.2 or 3.4GHz - and with either 1Mb L2 cache, or 2Mb??? I mean, where would the expense/time-advantage line be drawn - if such a thing can be quantified? Has anyone done a comparison for differing CPUs I can access? 8)

On a 2.8 GHz P4 I see a ~30 percent improvement in encoding speed with hyperthreading enabled. Be sure you have a fairly recent build of Xvid -- it wasn't multithreaded until about six (?) months ago.

overclock your 2.8 to 3.2 and see if it makes a difference. just bump the FSB, the northwoods are amazing at that.
