CCE RT 6.2..how is it possible

[mrbass]

I just got an P4 2.53Ghz with sis 648 gigabyte 8sg677. I only have crucial ddr 256mb 266Mhz. I encoded fantasia (120min movie) NTSC full screen, bicubic and it was 2.1 CCE speed. Before on my AMD 1700xp I'd get about CCE RT 1.2 for fullscreen bicubic and about 1.3 -1.5 for widescreen bicubic. So I'm reading around forums and many say they just up their fsb to 150 from 133 to get 2.85GHz which overclocks the memory to 300Mhz. How in the world can I be getting 6.29? I'll do a widescreen and see if I can't get 7.0 or 8.0.

edit: took out links since this whole thing was bogus..when it's oc'ed to the point of unstable it must be not processing it correctly or something really weird. I thought when I got my new memory it would be stable but it was at what I was attempting to do fsb 150...or 598Mhz bus.

FSB is very much a bottleneck in something as CPU-intensive as video encoding. This is a very extreme increase in speed, and even I wouldn't have thought it to be so great, but it comes as little surprise. The FSB is just that important. You'd be wise to get your hands on some DDR-333, with CL2 (if you can), and up your FSB even higher... you'll love the results ;)

Based on my advisor, UltimateDBZ, I took his advice and ordered
CORSAIR MEMORY XMS Extreme Memory Speed Series 512MB 32MX8 PC-3200C2
400MHz 64M x 64 CAS Latency 2-3-3-6-T1 it's only $187 at newegg. Nevertheless, it wasn't 100% stable cuz of the memory. I'll be sure to do a huge benchmarking comparison when I get it in a couple of days. IT's weird that my memory is gonna cost almost as much as my CPU but it looks like with video encoding it could have a HUGE impact on speed.

If you results are real then I am dumping AMD and going back to Intel.

If it wasn't you saying this I would really be thinking that you were nuts.

I am sure you checked it, but are you sure there isn't an Avisynth error there or something? Did the whole movie convert OK?

Could you convert a non animated movie and see what kind of speeds you get?

Very shortly there will be a new set of motherboards out with dual memory channels and I wonder what kind of speed you would get with these 128 bit wide busses. Of course that means 2 modules at a time, but with considerably more bandwidth stability.

I wish I could get my hands on a system like yours and test it myself. Very soon I will be building a HTPC and I would just scrap my regular computer for it and build a new one for my main PC.

Good to see you again mrbass.

@Mark: I wouldn't dump AMD (well I wouldn't at all) just yet. The FSB is going to be increased in the new Barton processors from AMD that will be coming out Q1 of next year (most likely late January-ish). This will _drastically_ improve AMD's position against Intel's in multimedia tasks such as video encoding. And later in Q2 when the new Hammer chips are released, along with the increased FSB, will be 64-bit support. Then you'll really (I mean really) see improvement in something like CCE.

The way I see it, is that once AMD comes out with Hammer, the only chance that Intel will still have to not fall behind is if it's plans for dual-interface DDR support come through, and are successful. But then again, paired with an nForce-2, AMD already has this base covered...

I still like Intel some, from back in the day when they were the best, and I would love to see them do some real reworking of their chips. It's seriously sad that their products perform the same as AMD's, but with hundreds (if not a thousand) less mhz. That's pitiful. They need to sit down and completely restructure their processors, perhaps for the release of the P5, so that it will be totally efficient as AMD's XP processors are now. Then they wouldn't have to pump up the core speed so much to improve performance. But then again, Intel's entire marketing scheme is based on brainwashing people into thinking mhz is the only thing that matters, so maybe they've purposely discarded the idea of reworking their processors entirely...

Who knows? Only time will tell...

@MrBass: I'll be very interested to know your encoding speed results once your FSB is pumped up to 166mhz. Please post them :) Also, assuming you've got a good cooler, I'd advise upping your core voltage a bit, to make sure the processor has all the power it needs.

I had this high a RT number too. But the whole thing was flaky. I would suggest to time the actual encode. My bitrate went up to 5, but the encode still lasted as it was 1.5. So don't waste a fortune for that number, perhaps a marker on the screen could give you the desired number as well?

[markrb]

UltimateDBZ unfortunetly if I am building a HTPC it will be in the next month or so.
My current thinking is to use my parts out of my running desktop for that and upgrade to whatever is the current fastest I can afford.
Right now that appears to be the P4 2.4(if I can get a C1 revision) or the P4 2.53. Both are or will be overclocking champs and will kill the current fastest XP (currently at the 2200+ with the 2600+ still not shipping).
The thing that kills me for Intel is cost, although they have been dropping lately the AMD cpu's are about 20-25% cheaper. The supporting motherboards are also quite a bit less.
Since this stuff has always changed so quickly the final choice won't be made until the last minute.

BTW if you didn't know AMD announced that Barton and Hammer are going to be delayed.

good point...I wouldn't have bought it but the .vaf file (120min) movie first screenshot shows 34min + 24min = 58mins...which it really did take.
Then upon overclocking it took only 20mins....so I believe the 6.2 is accurate. Not sure why perhaps cuz the L2 cache 2.85Ghz and FSB is running 598Mhz instead of 533Mhz perhaps..plus memory is cranked up too. Just a guess.

btw mark you can get 2.53Ghz retail for $232 @googlegear. I paid $247 but have 60 days to pricematch the difference. I never considered intel past 2 or 3 years till they dropped the price from $600 + to $250 or 63% price drop.

Barton is moved back to Q1 2K3 (as I believe I posted), and Hammer to follow in either Q2 or Q3, though I'm not sure if that last part is confirmed yet or not.

I, too, am rather irked that the 2600+ is not yet shipping. The 2700+ and 2800+ are already given release dates (which aren't very far into the near future), and the 2600+ hasn't even seen the light of day yet -_- I'll be glad when the day once again comes that Intel and AMD are neck-to-neck in BOTH price and performance. Then we'll begin to see true competition and innovation :)

ux-3 is correct it's totally bogus....dang.. I seem to have wasted $200 on memory just cuz I thought it was going be that fast. Anyway here are my pathetic results. I'll try doing simpleresize on at least one of the speeds for comparison sake.

1.87 is nothing to sneeze at.
It's no 6.0, which I honestly had my doubts on since it was so much higher, but it's a very good RT.
I wonder if the 2.8 overclocked could break the 2.0 mark?

6 did seem quite high, even to my wildest dreams, but your speed is still quite venerable. Most likely the money you spent isn't a waste, as you'll still see a nice increase in speed from higher FSB speeds.

[mrbass]

ok call me a traitor but I guess I'm gonna switch to simpleresize. SSE2 must be kicking in CCE RT 2.25. BTW I used the latest SimpleResize (doubt it makes any difference though). This is very similiar to what dvd2svcd has with his cce speeds dvd2svcd's comp specs (http://212.88.77.140/MyPC.html) with simpleresize with P4 2.4Ghz. I'll overclock it tonight and see what kinda speed I can get with simpleresize. http://www.mrbass.org/dvd2svcd/ccespeeds/
