    Hi, I'm planning on replacing my motherboard and CPU to an
    ASUS P5LD2 Deluxe and an Intel P4 3+ghz HT processor

    What type of encode times can I expect encoding to MPEG2 NTSC without any/may filters/effects in Vegas 6?

    Right now on my POS AMD 1800XP processor, it's taking about double realtime.. Are there any video encoding benchmarks I can read about that have done tests like this with the P4 processor? I saw one benchmark about encoding to MPEG4 that showed about half of realtime speed, but I'm more interested in MPEG2 for DVD

    Thanks

  2. Vegas is well multithreaded. You should consider a dual core processor:

    That's odd because I just got off the phone with videoguys.com and they said a dual core CPU wouldn't help at all in Vegas because they don't yet have support for taking advantage of the dual core processors........

    Would everyone agreet that Pentium 4 with HT is better than AMD for Vegas 6? I was told this because they said Vegas 6 can take advantage of the HT feature of the P4 chip...

    Thoughts?

  4. If Vegas can take advantage of Hyperthreading it will do even better with 2 real cores.

    Vegas 6 has new code packed inside that’s able to better take advantage of the power of dual processors, hyperthreading, as well as the new dual-core chips from Intel and AMD.

    but hyperthreading is an Intel technology right? Or does AMD have it too?

    Yes, only the Pentium 4 has Hyperthreading. But Hyperthreading is one CPU pretending to be two in order to take advantage of "spare" CPU cycles. You rarely get more than 10 or 15 percent more performance from Hyperthreading. You often get nearly twice the performance with dual core. Both AMD and Intel have dual core processors.

    interesting,,, then I wonder why the guy at videoguys.com (who are quite knowledgable) told me that Vegas doesn't have support for dual core processors ?

    Pentium D 830 is one hell of a buy and great performance, I may go with that one

    i have both a dual core and a full legal copy of Vegas 6 and can confirm that Vegas 6 is in fact very well multithreaded.

    the only way an app can take advantage of a hyperthreaded cpu is if it's multithreaded, in other words, if an app can take advantage of HT it can take advantage of dual cores.

    having said that, the limiting factor becomes the codec used, if the codec isn't multithreaded, it doesn't matter if the app is. on the other hand, all mpeg-2 codecs are multithreaded, so if ,peg-2 encoding is your thing, then Vegas 6 + dual core is a nice combo.

    What do you think about the 805, 820 and 830 chips then? Why do you think there's such a huge difference in the encoding times on the chart between the 820 and 830? Which dual core do you have?

  12. The Pentium D 805 isn't on the list because it wasn't available at that time. It's only 2.66 GHz, runs a 533 MHz FSB, and has half as much cache, but it sells for a mere ~US$135.

    Anandtech reviewed it recently:

    http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2736

    It appears to be very overclockable too:

    I have an Athlon 64 X2 3800+. I don't have Vegas but TMPGEnc Plus runs twice as fast when both cores are used.

    Wow, amazing; how difficult is it to overclock a CPU?
    oh yeah, which dual core do you use?

    huge difference? the difference between the two is 11 seconds, look at the encode times.

    to answer your question, i own the D 820 and as for what i think of about it, you can read the article i wrote:

    http://manicgeeks.com/viewstory.php?id=137

    as well this follow up:

    http://manicgeeks.com/forum/index.php?webtag=TECH&msg=3253.1

    in a nutshell, i would recommend a dual core athlon over a dual core P4, no matter how cheap the P4 is.

    Hmmm, interesting articles! Now I don't know whether to go with a single core P4 3+ HT or the dual core.... From an encoding only stand point, would you agree that the single core hyper threading processor is the way to go? I don't plan on doing a million different things while my video encodes...

    Maybe Deadrats will run a comparison for you: Vegas encoding with his Pentium D with one core, then two. Then on his Pentium 4 with and without hyperthreading. If I had Vegas I'd run some benchmarks for you on my A64 X2. As I said earlier, TEMPGEnc runs twice as fast with two cores on my dual core system.

    If you think thermal throttling will be an issue for you all you need to to is get a decent aftermarket CPU cooler, $30-$50, and more/better case fans.

    if you were to building a pc dedicated to video encoding or you plan on simply letting your pc encode overnight while you sleep and you plan on using the stock cooling, then yes, a single core HT enabled P4, such as a 630, maybe even overclocked to 3.5ghz, would be the way to go.

    if you could find a good cooling solution, then a dual core P4 would be the way to go. the problem is finding a good cooling solution that will cool the dual core P4's enough so that thermal throttling isn't an issue.

    having said this, more important than the cpu is the motherboard and ram, because if you use a cheapo motherboard/ram combo, the cpu will be held back.

    i don't recommend the hybrid boards, like the ones i have, i strongly recommend using an intel chipset coupled with fast ram, preferably DDR2-667 and SATA drives, 2 of them, reading from one and writing to the other.

    the D 805's are really hobbled by that 533 mhz fsb, each core communicates with the other core via the fsb, which means the faster the fsb the faster each core can communicate with each other and the faster it can communicate with the memory controller on the north bridge. in short, 2 cores means twice the latency, that's why you see such a small increase in performance for a relatively large bump in clock speed.

    get yourself a HT enabled single core P4, the fastest one you can afford with a good motherboard and fast ram, you won't be sorry.

    i've already done such a comparison, at stock speeds, with the D 820 @ 2.8ghz and the 630 @ 3ghz, if the encode is for a short duration and the codec used is multithreaded, then the D 820 beats the 630 hands down. if the encode is for a short duration but the codec is only partially multithreaded or single threaded, the 630 wins easily.

    if the encode is for a long duration, like for more than 2 hours, the 630 beats the D 820 by varying amounts, at times by over half an hour.

    if i underclock the D 820 to 2.33 ghz, for short encodes it loses by small amounts to when it's clocked at 2.8ghz. if the encode is for a longer time, say 2 hours worth of video, then the D 820 underclocked to 2.33ghz smokes the 2.8ghz setting by hours.

    in short, the D 820 with stock cooling suffers from thermal throttling real bad, if you can pair it with a good cooling solution (like liquid nitrogen or the south pole) then it can live up to it's full potential as a little speed demon.
