Ok isn’t Intel meant to be faster in Audio & Video encoding then Amd?

[Winxp]

Ok I came from Amd was running it at 2.3g 24/7 in summer, now that I have a P4 2.4c@3.4g I was expecting faster results but I was wrong!!!!

OK my Amd at 2.3g did Audio encoding in 25-30min depending on the length of the movie.
Intel at 3.4g 293FSB 320MHz, is doing it in 1h now what’s whit that?

I came from AMD to INTEL to get faster results

So is this true or is it just me?

I see better scores in Sandra, PC-Mark 02 then Amd which is good but once comes to encoding its heaps slower even a 2200xp@ at 2g was faster
Just tell me what u think I might be doing some think wrong?

ASUS P4P800
2x256MB XMS REV:1.1
2.4C@3.4G

ouch...
my p4 2.8 (HT disabled) encode an ac3 (100min about ) to mp3 (besweet .25) in about 15 minutes...

Installed every driver, chipset and so on ?

Yes

[buzzqw]

is cpu at 100% during encoding time ?
is stable your os (winxp, i suppose) ? even at this overclock ?
are you running many other task during encoding ? (like encoding another video, as i usually do ...)
try headac3he-0.23a (just for test)
Defrag ? NTFS or Fat32 ?
Mersenne prime ? Memtest86 ?

P4 vs Athlon performance depends a lot on the software used.
Generally, AMD is stronger on MMX/FPU code, but the P4 is faster when using SSE2. Older SW, optimized for P3/Athlon does not use SSE2.

I had big expextations as I bought a p4 2.8 ghz as I have two amd xp a 1800 and a 2400. Intel can't beat neither of them.
I would change to amdxp back again if I could.

The cpu is at 50%
Yes stable
Not running much
I use NTFS
And prime

Ok will try dl the headac3he-0.23a

[Winxp]

Well what program for Audio and Video uses SSE2 for support P4-c?

EDIT: Was looking for headac3he-0.23a couldnt find it any one have links for these? THX

EDIT: Just DL the DVD2AVI dg it does it in 11mins but it saves the file as .AS3 I need .WAW file how can i do this?

AS3 ??? What is this kind of audio? (search in audio forum section)

In audio option check
channel format : auto select
dolby digital: demux all tracks,(set Decode for wav output file)
mpeg audio : demux all tracks
48-44khz : off

you would have an dts/ac3/mpa/wav but as3 ...

@WinXP:

The cpu is at 50%

Here is the reason. I guess you've got HT enabled. Try to disable it and then share your results...

As I sad it's faster it does it in about 10-12 mins in Audio that’s all good But I can’t find a Video encoding program that would be that fast I am use to TMPG any Ideas which version I should get?

@Winxp:

Ahoj!

What about VirtualDub & XviD? You can tweak it a lot and I bet you'd find some compromise between quality and speed there...

If I might shed some light. While the Intel has a higher clock speed and so on and in most results that would seem that an Intel would beat out an AMD, except for one overlooked item. This is where the AMD people have really done their homework. An AMD Athlon executes more instructions per cycle. Example: Car running down road. Has faster revving engine, but smaller pistons, and has to "rev" up to provide the necessary horsepower for a 2500 lb automobile (Intel). Car running down road has large pistons that take in more air/fuel and can create the same horsepower but at a lower rpm due to the internal size of the each cylinder firing and does not need to run at excessive high rmp (clock cycles) to attain the same speed to get a 2500 lb car down the road (AMD)

If I knew how to put in a picture I have a great one to show a comparison of these and what I'm talking about. MWIPS is one measure ... Million Write Instruction Per Second my AMD does 6,137 Million/second.. an Intel Pentium 4 at 1.8 GHz writes 1,252 Million/second as a comparison.

OK guys, I have a sinple doubt.

How would you calculate AMD AthlonXP's speed as in GHZ if its specification shows 2600+ ??
Do it mean its 2.6 Ghz or more ?

One more, What cache sizes are used in AMD?
I know intel P4 uses 512KB L2 cache and 8KB L1(AFIAK), similarly in AMD?

Thanks.

"How would you calculate AMD AthlonXP's speed as in GHZ if its specification shows 2600+ ??"
Nope, 2600+ is not 2.6 GHz it's more like 1.7 GHz in actuality. My AMD Barton 2500+ is somewhere around 1.83, but I run it around 2.1 GHz and there are others that have tweaked their systmes a bit more to achive a higer clock rate, usually done with adjusting the FSB (Front Side Bus) up a bit, and then with multipliers.

"One more, What cache sizes are used in AMD?"
The AMD Athlons (Thoroughbreed, Thunderbird, -XP) have an L2 cache of 256 KB, the Barton core processors L2 cache of 512 KB (along with an increased FSB of 333) The newer processors, have a higher FSB and a cache of 1 MB Also they are true 64 bit proccessor chips, receiveing and sending 64 bits per instruction. (they are QUITE fast).

might try this web site for a LOT more info on the AMD... http://www.amdmb.com/index.php

Ok guys what program like TMPG will support SSE2 THX

[port66]

amd cpu names gives the game away. 2800+ will run like a p4 2.8, even if the coreclock of the athlon is 2,1

[Tuning]

Thanks vljenewein and Port66 for answering my stupid questions.
And btw, port66 welcome to doom9 forums.

Sorry for another question, do 3D now variants of optimizations are better than SSE variants?



@WinXP

TMPG supports SSE2 and future version Of it calle TMPG express as in www.doom9.org news says support SSE3.

VirtualDub and divx/Xvid codecs also support SSE2. You question was already answered by mikeson.
