Question about upgrading...

[RealaT]

Does anyone know what difference ram makes on encoding speed using TMPGEnc? My PC takes roughly 3x length to re-encode a DVD film (I have a 1.4ghz athlon). My friend's machine only takes about 1.5x (He has athlon XP 1600+). This seems like a big performance leap for such a small increase in speed seeing as the 1600+ runs at 1.47ghz. The onbly thing I can think of is that my PC uses 133mhz sdram and my friend uses ddr ram.

If anyone can shed some light on the subject it would be great

You can check any memory site and read the difference between sdram and ddr ram ,
The difference is , sdram only reads in one direction and ddr reads in two directions ,if my memory servers me correctly
Better the memory , better the performance ...
But don't take my word for it ,,, ( check it ) hope this helps ...

I have two XP1600 computers,one with 256Mb of DDR and one with 128MB of SDRAM. There is NO difference in encode speed. Ram really doesn't effect encode speed,unless you have too little for the ystem in general. Raw Ghz of CPU,Ultra DMA active on the HD,and the rotational speed of the HD are what matters. Not haveing ultra DMA tuned on could cause a 1/2 speed difference.

Raw Ghz of CPU

that's not necessarily true. athlons performance is comparable to pentiums of higher clockspeed.

something like athlon 1.6 gightz has same performanc as pentium 2 gightz...(not sure if exact numbers are right, but something similar)

Here's my input...
Whenever your powerful 1.6GHZ and 2.0GHZ machines have to access your system memory, it must slow down to the memory speed. And it does this when it can't find the information it needs in the CPU's cache (see cache hit ratio). Currently, DDR memory runs at 200/266/and (333?). With that being said, I recommend no less than DDR memory these days. BUT, I am unsure what effect this has on encoding times. Exactly how much different data must be accessed from main memory during a encode process? Maybe not much based on someone's observation a few posts up. If you are buying or upgrading, I'd go with DDR, unless you can afford that RAMBUS stuff (800MHZ I think).

i have sddram 512 and a 1.8 pentium 4 i do a 2 hour movie (avi) in 30 - 40 mins but iusually do music videos. a 4 minute in about 2-3 minute. shut off virus protection take down that fancy wall paper and keep desktop icons to a minimum while encoding all thes take up valuable ram and it will help!
