Using Hyper-Threading with Tmpgenc.

[digicube]

I have a 2.4 HT with 800 FSB with some PC3200 RAM and to convert a 9 minute clip it takes about 3 minutes, sometimes alittle less, sometimes alittle more. Coverting a 31 minute clip took 11 minutes and so on.

Quite a jump from what it used to take.

The best part is my motherboard supports up to like a 3ghz CPU so this fall when prices drop again I might pick up a new CPU.

Oh and thanks again BJ_M

I have almost the same computer specs as you. What kind of conversion are you doing? It looks really fast. Is it Divx to VCD or something else? Have you tried Divx/Xvid to DVD (How fast is it)?

What does the cache setting do? Does it always increase the conversion speed regardless of project coversion setting or do you have to turn on multi-pass VBR or something of that nature?

Cache, if anything, will help reduce latencies and such, so it will probably give you a slight speed boost.

My boss ia getting me a new PC with a 2.4GHz P4 with the 800MHz FSB and Hyperthreading, 1Gig DDR Ram, a Serial ATA drive, GeForce 5200 FX Ultra and a DVD+R/RW next week!

Do your self a favor, get the Radeon 9800

ok, here's my results for encoding an avi file (~6GB, ~30 minutes):

You can examine my system specs in the profile. EDIT: sorry, in Computer Details.

No filters selected.
2 pass vbr (4000 min, 8000 max)
every thing else standard DVD-NTSC template

On the CPU tab of Environmental Settings:
With hyper-threading disabled in the bios, multi-threading enabled in CPU environment tab, 256MB prefetch video and 4096MB cache

1:04:15

With hyper-threading enabled in the bios, hyper-threading enabled in CPU environment tab, 256MB prefetch video and 4096MB cache

0:55:56

Not much of a difference IMHO. Am I doing something wrong or are there other suggestions on the encoding specs. I can run some other configurations if someone is curious about other setttings.

when u dont enable hyper-thread in bios, u probably shouldn't in software.

Are you saying that hyper-threading and multi-threading are the same? In that case you're right I did not disable multi-threading in Options->Environmental Settings->CPU when I disabled hyper-threading in bios. That could explain why there is little difference. I didn't think they were the same beast but on second glance, the choice reads as follows:

Use Hyper-Threading Technology (multi-threaded)

I'm going to take a small, about 1 minute clip, and run with different environmental settings and different encoder settings. It will take me a few days since I have to work this weekend but I'll post results when done.

After much gnashing of teeth and what not, I've tallied some numbers using TMPGEnc on a 00:01:03 avi clip on my home computer and my work computer. The results can be found here:

If you would like to see some other set of numbers just say so. I can also produce numbers on a 700MHz P3 laptop if that's of any interest.

obiron,

Thanks for the info, some very interesting results there.
