Well I know there is more to this than just CPU speed, meaning the drives etc, but today I ripped three dvds the last 3 from band of brothers to make a backup copy.

I have three main pcs I use not including a few others, and here are the speeds I got for DVD shrink with 3 DVDs.

Intel Dothan 1.8ghz laptop - ripped and encoded disc in 32 minutes
AMD 64+ 3800 laptop - ripped and encoded disc in 34 minutes
Extreme Edition @ 3.9ghz - ripped and encoded a disc in *12 minutes 30 seconds

All have 1 gig of ram** windows XP pro SP2........... interesting results.


*EDIT: meant 12 minutes not 16.
**EDIT2: urghh sunday night, the EE has 2 gig of ram @ 800mhz........

mike2h

was there any compression involved? burner speed?
desktop will always be faster than a laptop with similar 'rated' cpu.
the destop time is very good. which vers of shrink were you using?i use 3.2 for most use, 2.3 if i am going to re-author.
i think this is an area were intel shines. especially with your cpu.(me want).
i have B.O.B. a little later i will see what i get. let me know what vers of shrink & compression settings. & we will do a head to head. i have 2.4@3.035 with 1gig ram at 1:1 ratio & a 74gig raptor with the swap file on its own partition on a sata 'cuda & a 8x plextor.
bty, what are you using to extract?

well, that is even more impressive. any more urghhs ?

nah all my urghs are done for today, hopefully

Ok, this was far from a highly accurate comparison just an observation I made while going out of the room for a while, the differences were a lot larger than I expected. I was just looking to copy 3 DVDS as fast as possible so used 3 machines.

all machines were win XP sp2 pro. both laptops had 1 gig of ram. the A64+ is DDR400 and the dothan is just DDR333 I think.

All versions of shrink were the newest 3.2 and compression, im not sure about to be honest I think most were around 70%. All just used DVD shrinks default settings to get the data onto a single layered DVD.

The Intel EE handled disc 5, the dothan disc 4 and the A64 disc 6. (BOB - UK).

I have a feeling intel are good for this as the dothan made up for 500mhz of clock speed with a larger cache (2 meg), whereas the A64 on a 32 bit os with the smaller cache ripped and converted the DVD in slightly slower times.

The EE walked it, but then as you say, its a desktop and overclocked quite a bit with a 1200fsb and 2 gig of OCZ running at DDR800. the desktop hard drive was a samsung 300 gb 16 meg cache drive, whereas the dothan is a 60 gig 5400 RPM, the A64 is an IBM 7200 60gig. both laptops have NEC DVD drives, the dothan being the NEC6100 dual layer... the desktop DVD burner is some cheap japanese 8x drive I picked up and to be honest isnt that hot, but it works and seems to handle most things pretty well.

I noticed on the Intel EE ripping speeds were in the 7500mbs-8000 range whereas both laptops seemed around half the speed.

mike2h

thx. it sounds like you went with default settings with shrink. i'll do the same. as soon as the game is over i'll give it a shot. mine does it pretty fast so it will be kinda cool to see what the diff. is.
B.O.B. is awsome imo. think it is one of the best, if not the best, war movie ever made. definitely the best miniseries ever. by a large margin.
anyway i'll be back with a time later.

It also seems to help have a temp. folder for Shrink on another drive than the OS drive and/or page file.

Zardon

Yeah probably true. as I said this wasnt an indepth technical analysis as I would need to run the same disc on each computer and make sure all the settings were the same and would need to make sure everything was ran as close as possible, it was more an observation in a real world situation.

Incidentally all the rips were to the OS/boot drive, which would probably slow them down a little.

mike2h

okay, got a total time of 23 mins. 15 to extract/encode & 8 to burn.
zardon, are you sure about the time? since your burner is the same speed as mine(8X) that means you comp extracted & encoded those files in about 4 mins. while your machine is considerably faster than mine there is still the problem of the extraction speed of whatever optical drive you were using.
my comp does not have a seperate dvd rom drive, but the plextor is stiil very fast at extraction for a burner.
it started the encoding process in the mid 4,000's & ended up around 7,000. this is very good for a burner. i would say average was upper 5's. jmo.
this means your optical source had to be operating at 16-20,000 the whole time. that is not happening.
so either you got your time mixed up, i am dazed & confused on the math, something in the middle, or something else.
personally i think your original 16 mins was closer to real time, but then again, what do i know?
what do you think?
bty i agree with necrosis, while my movie folder is on the os hd(different partition) my swap file is on another hd & seperate sata channel.

hmmm, nice shiny object . looks very, very nice there. thx!

No it was under 13 minutes, im totally sure, the reason I typed 16 initially was due to the fact im old and was talking to someone on MSN about something else relating to 16

I can rerun it and take a screenshot if you like later when I get home, I certainly dont waste time making something up

EDIT: I didnt include the burn time, you did - makes more sense now eh?

so my system took 12.30 to extract and encode, yours took 15...

mike2h

i did not doubt your veracity. the urghhs' gave me a little doubt.
guess if i would have paid attention to what i was reading i would have caught that fact. me bad.
times for my machine are very good. yours is just, well, FAST.
i'll be looking at one of those EE cpu next year when the price(hopefully) goes way down. unfortunately i think 3.2 is going to be it for socket 478. still if i can get an equivalent oc to what i am doing(or better yet, yours) now that will give me a nice boost. unless powerleap can come up with another of their nifty adapters, then things can get interesting.

think i will try it on my wifes machine tomorrow. i'll post her specs then.
without the burning the disk this time.

I suppose the CPU is limited quite a bit by the speed of the burner on reading and extracting. I guess the cheapass japanese dvd drive I have isnt too bad

pr0digal jenius

is BoB dual layer?

because it's taking me 23 minutes to 'backup' Viva Le Bam Season 1, which doesn't sound right at all....

sounds like your optical drive aint too fast. BOB is dual layer, but you should be hitting 7,000+ as you get mid way into the disc.

mike2h

are you using your burner to extract? most burners have a built in speed limitation when it come to extracting. the speed you give is an that ball park- 2.5 - 3000.
it is part of their scheme to discourage copying.
this is why it is nice to have a seperate dvd rom drive or a burner like the plextors that cirumvents this.
if you used a dvdrom then you have other issues.
also, the amount of compression makes a huge difference.
i have also noticed that some movie are laid out in such a way that they seem to encode slower than other movies that are the same size.

i just ran disk 5 on my wifes comp- p4 2.6a @2.73(no ht), 768rdram, 16x dvdrom, 2.4x dvd burner, maxtor 80gig(sys), 2x maxtor 40gigs in raid0(128 kb sectors) this the drive i use for movies- encoded in 17 mins.
so, what we are seeing is what common sense tells us to be true, fast encoding is a blend of cpu, optical drive, & hd performance.(everything else being equal). i think amount of mem is only secondary once you are over 512.
& ht does make a diff. i can do other things on my comp while encoding & it makes no difference(within reason) at all. multitasking on my wifes comp while encoding is another matter. it can be done, just get slow.
fyi i have encoded & burned at the same time on hers.

i was using version 3.1 on a cheap sony DVD-RW drive at default settings

Zardon

time you put those old xeons out to pasture

pr0digal jenius

lol...you replacing them with noconas?

o well...if anyone starts an AVI->DVD thread, I'm sure I'll do much better

mike2h

pj, try 3.2 out. & use a seperate dvd rom drive. that sony is extracting real slow.
before you back up a movie(if you do not do this already) uncheck all the french, spanish,etc, files.
if it is more than about 110 mins you might want to consider reauthoring & just backing up the movie itself. this gets rid of all the menus, 'extras', whatever. which means less compression. this leads to faster encoding & better quality.
do not know if you knew this already, just thought i would pass it along.
