What Machine should I buy to perform RV9 - EHQ=80 realtime encoding ?

[ToiletDuck]

I have dual opteron 240's@1.5ghz. MSI K8T800 motherboard. 1gb 4x256pc3200ram. 3x120gb harddrives. 1x60gb 8mb cache harddrive. 1x30gb drive.

2x240's=$382
motherboard=$225
ram=$197
-------------------
$804

$804 at dell gets you-Dimension2400 with integrated audio and graphics and pentium 4 2.66ghz... gotta love building your own. The rest of my system is about 2 years old. I get parts here and there. Rest is ATI 9700pro, 4.1 surround sound, 21" trinitron monitor(Flat screen not panel) and soundblaster extigy soundcard.

For encoding I usually do 640xXXX after cropping. I use autoRV10 for my encodes. I was using xvid but have been having some lockup issues that I can't explain on the second pass of the codec.

However as cheap as DVD burners are getting it almost seems like in 2-3yrs that divx, xvid, and all other codecs will not be needed anymore.
Why not H.264 -> DivX 6 n' XviD 2 or WMV10 to fix 120 min. HD content on a DVD5 !?!

Well......... MY GOD!...... i would consider anybody have a ATthlon 64 to be rich already and you got a Dual Opetron!!!!!!!!!!

Anywayi heard that D0 Core of Prescott in Socket T ( aka LGA 775 ) is suppose to improve things and add the speed up to 3.6 GHz.

So i may have to be a bit more paitent with Intel.

Considering Even with the topest Computer we still can't do Real Time Rv10 encode..........( And yet there is H.2x4 ) i am now convine why we need things like a 10 GHz 64 Bit CPU.... :D

[ToiletDuck]

Not rich lol. Build your own and you would be suprised. I work for dell right now while in college and can tell you that every computer sold has at least 30% margin or more between the price to build and price to cost. All the time I sell $1400 systems that have $1100 in margin. The total cost of my system is about $1400. That isn't rich. That is just looking around and taking advantage of opportunities when they arise. My 21" monitor that sells for $450 at Dell(mine actually is the same exact dell) I bought on ebay for $150. Want some tips to build a great system for cheap. Look on ebay at 2am. Tons of people post things and don't set the time at which the auction ends. At 2am no one is awake and no one is bidding and I snatch up some great deals! Also I buy things that I can keep for a long time. Such as the monitor and sound card. Those things stay. So whenever I want a new system I just get a new motherboard, ram, and chips and BOOM. thats it. Not to hurt anyone's feelings but if you are sitting on a dell, gateway, any computer you didnt build yourself, then you could have gotten way more for your money just by building it yourself. It is also very interesting and a great learning experience to do this. If you have any questions about how to build ultimate computers for cheap go around www.overclockers.com. Great people there.

I've also heard that divx and such use live streaming data so cache doesn't matter. However I find this odd. Anyway if any of you are wondering what you could get for a pricerange PM me a quote. I'd be more than happy to see what kind of system you could get for your cash. I'll even compare it to what you could get for that amount if you ordered from me at Dell or called Gateway.

Happy encoding!

most like the dual opterons are for the porno rips right??? all the porno vids are in freakin Xvids and wmv9's

awesome freakin quality too if i may say so ;)

Divx, WM9, (don't know about that hobo RM :)), most encoders use *big* data sets up to 10 frames long. That means memory bandwidth, and to save memory bandwidth... CACHE.
That's why my EE just burns through WM9.
At least that's what I've gathered from my research over the years...

well as far as waiting for the new prescott socket, who knows. There have been so many rumours, ill just wait and see, it may not be as glorious as they say. whne i can see the ahtlon socket 939 out as well as the socket T then I can compare. As far as encoding goes, its very true intel chips outpace since they are mhz hungry type apps, granted there are many that are optimized for intel chips anyway. SSE3 will be implimented in the new socket 939 for amd so that advatange will be gone. Maybe, if we are lucky, Id like to see more amd optimized codecs for testing, such as 64bit capable. Eitehr way, itll still be several months before we see much of anything.

[karl_lillevold]

Like I wrote in an early post in this thread, RV10 encoding gains around 5% from the new SSE3 instructions on Prescott. However, what is really nice is that finally, due to increase cache sizes, hyper-threading actually makes a difference for encoding (it was always good for the decoder). I measured an additional 20% speedup from running the encoder in dual threaded mode, on a single CPU Prescott system with HT enabled, provided by Intel. So a total of 25% is not bad. Unfortunately, I still have not seen or been able to try RV10 encoding on AMD64, but I am curious how it performs.

[Sharktooth]

i have a dual 248 opteron. dont know how it performs on RV9-10 coz i dont like realmedia stuff...
however i can easily compare other codecs performance on single and dual processor mode.
the average gain on a beta build of windows xp for 64 bit extended processors (divx standard settings) is about 80% (from single to dual) and a freaking 220% comparing the dual 248 with my old athlon 2600+ @ 3200+.
as soon as i have some spare time i will post some logs and stuff...

edit: i've just acquired from some internet sources that the new athlon 64 models (newcastle core) should have 1Ghz FSB (200x5) and SSE3 support...

[ToiletDuck]

and i was just starting to love this system :)

[iwod]

Well...... ok may be you are not rich. Just that i am Poor. :)

I don't 100% agree that Encoder are Mhz type app statement. The only reason why todays encoder are faster on INtel is simply becoz they are ALL optimize for intel chip. ( Or say they don't have a AMD chip in their test lap. )

Either intel have lost track of what they are doing or they have something in hand. Prescott doesn't look too bright with all these Heat and power problem. While AMD Athlon 64 got a long way to go before they really need to move on to 0.09 um.

@ Karl. Yea i remember you said HT does not speed anything up in encoding when it was Northwood time. So has the prescott with 1 M cache and HT improved the speed by 20%, is that what you mean?

Or are you referring to P4EE?

( Because If Prescott HT improve Encoding by 20% then it would be a totally different perpective.... )

[Sharktooth]

The prescot advantage in encoding is not due to HT.
Its SSE3 and the larger cache that matters.
However if you search on the web there are news about the newcastle core for AMD 64 cpus talking about 1Ghz FSB and SSE3 support.

[bill_baroud]

But don't forget the prescott's cache latency which is almost twice as northwood's cache !
Atm, prescott are like the first p4 willamette, i.e they are designed to run at 4ghz and more, they can't compete with actual northwood at the same frequency... and they are going soon to change the socket (478 to LGA775) so prescott aren't definitly an option.

And for the reason why p4 perform always so well in encoding app is 1) because a lot of those app are heavily optimized for p4 and 2) p4 are designed for that task, i.e computing (integer) "data stream" with no unpredictible branching, which is typically a video encoding :)

To my mind, one of the compelling reasons why AMD's Athlon has endeared itself to the enthusiast's heart is the fact that right out of the box it is such a powerful and capable architecture without having to rely so much on software optimization and special instruction sets, etc etc. Makes me wonder how the competition would fare if the Athlon has only received as much attention and its own optimizations from those major developers. It's a bit silly, that for all the strong performance achievements it has shown since it first came out, so many are still unable to give it the credit that it rightfully deserves. The general mindset is still "AMD is just a cheap second-rate catch-up player". It is a mentality that I witness everyday in my office, in some friends and of course some of the tech forums.

[Wolfman]

Another point about CPU's etc is that I/most people dont compare 2.6 athlon with 2.6intel and then say, ahh intel fastest, NO. People say I have £65 to spend on a cpu and Mobo, what is the best I can get for that?? inevitably if your on a budget AMD is cheaper. price per VEB Amd is normally cheaper.

For realtime encoding in rv9 EHQ=110?? Beowulf cluster 64 sun sparcs running Linux .. 10 teraflops computing power.(as no budget given!):rolleyes:

[ToiletDuck]

bah. I imagine that dual opteron 248's should be able to. I'm not too far off with my 240's. They are overclocked to 1500mhz but a 2.2-2.5ghz pair of opterons should do the job nicely.

my dual 248 eats everything the universe throw at it:)
