I've got a P4 2.4 gig machine now running XP, largely want to improve
rendering speed for video editing, how much processor do I need in the
Core 2 Duo realm to realize a healthy jump in speed? Not too proud to
go used, can't afford the latest greatest, but would like to see a
"significant" jump in speed.
What kind of numbers should I be looking for, and any suggestions on
pieces to look for or avoid?
Thanks for all input.
OK, for any CPU-intensive task, you want the fastest clock speed (GHz)
you can afford, paired with the most cache memory you can afford. Once
you figure that out, if you have extra money then you can add more
1) Core 2 Duo 3.0GHz 6MB cache (if that beast exists)
2) Core 2 Quad 2.4GHz 8MB cache (if that beast exists)
Number one would be significantly faster due to the higher clock speed.
But you asked about video editing. That is one specific application
where video card (speed), RAM (quantity) and hard drive (speed) all
play a part.
For video editing, look for:
64-bit OS with 6-8GB of RAM
7200RPM hard drive with 32MB of cache
A recent mid-range video card like a HD 4770 or similar with 1GB of
dedicated video RAM
Your system might have other glaring weaknesses that will slow down
video rendering more than a single core 2.4GHz CPU will. For example,
if you have 2GB of RAM and are using "integrated" (on the motherboard)
graphics adapter, then upgrading to a faster CPU will offer no
performance improvement at all. -Dave
