Is DVD Encoding more memory intensive or CPU.

[mikef07]

Take for instance two computers:

Comp 1- 2.7Ghz 512MB RAM (Memory running at 375Mhz)

Comp 2- 3Ghz 512MB RAM (Memory running at 333 Mhz)


Which of these will perform better??

cpu intensive ... memory doesnt mater a whole bunch

[mikef07]

cpu intensive ... memory doesnt mater a whole bunch

So I would be better off running at 3Ghz rather than 2.7 with faster memory??

when u are talking raw power it is cpu but the mem speed makes a good dif. Take a AMD at 133 and a multiplyer of 14, then mod then mod the CPU and change to 200 and a miltiplyer of say 8 almost same CPU speed but encode time drops a lot. So amount of mem after 512 is not really needed but the speed of the mem makes a sizable diff. Hope this helps.

It depends on what your doing, but for the most part mpeg encoding speed will speed up based on CPU. However now that I'm using DVD2ONE primarily the CPU isn't the weakest link any longer, but rather the hardrives are. Having a good RAID setup will bennifet when writing or reading large amounts of data from the hardrive.

I have the raid setup. 360GB of total HD space. Of option 1 or 2 which would u choose?

If your memory is so slow that it starves the CPU, your memory speed will need to increased. However, most memory nowadays is plenty fast for the processor (FSB > 100MHz).

So, your 3GHz machine will perform better (I'd say ~ 10% better).

There are things that can speed up encoding, by eliminating bottlenecks - like reading data from one physical harddrive and writing to another. Just bring up Windows Taskmanager and view the performance charts. You should see the CPU utilization at 100%, while your memory will be puttering along at around 10-20%.
