CPU's may be obsolete for video rendering via CUDA,,,or not?

Hi sorry newb again here, hope Chaz is still with the forums...

I'm dong simple rendering in HDV via Sony Platinum, which has become the non-linear editor of choice (along with Canon HV20!) for amateurs/prosumers.

The primary reason is the quality. However, as some of you probably realize, editing HDV (1440x 1080, 1.33 pixel ratio to upconvert to 1080 tv's) takes a lot of horsepower. I've found that my Clevo M590k from 2 years ago with a ML44 Turuion is hopeless. However, it would seem that added some effects, even a speedy quadcore is really slow.

So my quest for more cores (Vegas does multitask as far as I know). H

However, instead of investing in a 2x4core opteron sli system, with probably 4x10 gflops, why not use the 250-60 gflops of the graphics cards?

Looking at Elemental Technologies, a start-up from p-town, oregon, (yay!! go the Dungeness!!--mm ymmy..)- but the question is whether one goes for a dual or quad CPU (quad-core e.g. TYan) or will this tech (CUDA) make it obsolete...given like the lady said.---it's not going to happen as NvidiaÌntel etc. will not support plug-ins....

Any thoughts? As far as I'm concerned, if they can speed up rendering especially in sli....via CUDA or whatever....the latest XEON's go for over $1300. Barfff.....

It's not there yet, but I finally found a site*/startup that's using CUDA on g80 and later cards to render HDV etc faster. Not yet on my gpu's (dual 7900's
), but will be out october with speed-up for adobe premiere.

Students....if you really want a rendering machine...or anyoe else...I havene't used adobe.....but usd 340? for the academic version, + a pair of 8800 or similar in SLI, which should come down massively in price...let's start nagging the developers...under video/CUDA nvidia...

Sorry guys, got a bit frustrated trying to render HDV on a turion ML-44 (aka Clevo M590k) - but still the best screen and highest NITS bar none.

 

You have the 20" laptop, that is so sick, I am repping you for that

I have a quad dual core opteron server based on four dual core opteron 885 server processors. They do suck a ton of power, and they are running on a Tyan Tomcat motherboard. However, this Tyan board is before the use of pcie in servers, so I have PCI graphics and of course the onboard 8mb ati rage.

You will get a ton more performance out of amd opteron processors than even the fastest Xeon processors. Do not go for the barcelona's as they are crap. You are looking for the 2200 and 8200 series processors from AMD. The 8222 is the fastest dual core processor ever made. This processor will own any dual or quad core intel xeon processor.
AMD has been the king in server environments since the release of their first opteron core back in 2002.
You do not hear much about amd server chips, because they are not reviewed, since just about 100% of the consumers do not use server chips in their systems.

I recommend getting a Tyan board which can support four processors, but only get two opteron processors, as you can always upgrade to 4 dual core's later on.
However, these processors suck a lot of power, so you will need 1000watt psu minimum. My quad 885's will not run with a 750 quad psu, I need to use that and a 300watt AT power supply to turn my system on.

You are looking at a very expensive system, so be prepared when you see how much its going to cost.

try to get a tyan board which doesnt use fb-dimm memory, cause fb-dimms are really expensive.

I am not sure if their is any rendering software which can utilize the gpu's power.

intel platforms>opterons. do some more research ktron.

there is a youtube video of elemental technologies' RapiHD on gtx 280s (might be gx2s, not totally sure). it was really fast, but only a few profiles.

 

I dont know what you are talking about my friend, I have a quad dual core system, and it will annihalate any 8 core xeon system. Your fastest 8 core xeon system, with two quad cores, will get you about 92,000mflops. Each of my 885's can get 27,310mflops of power, which is significantly more than any xeon system. Opteron processors do not have one cpu to fsb link like Intel's do, they have three of them, which run at teh clock speed of the processor. The Opteron's are also designed to be run at 100% load, so they can take the heat. Opteron's also have integrated memory controllers, so their memory bandwidth is much greater and they have full support of ecc memory, whereas intel systems do not.
Your statement is true for desktop and mobile processors, but not in the server department. Amd has been king in the server department for years, and that is why most servers on the market are AMD based.
I know the RPI supercomputer is powered by Opteron 8222SE processors, and a whole lot of them, which crank out 120 teraflops of power, making if one of the top five super computers in the world.

your behind the times. http://it.anandtech.com/IT/showdoc.aspx?i=3335&p=11

 

Yeah, that is with the barcelona opteron, which has major flaws. The cpu's I am talking about are the 3.0Ghz dual core's from AMD. The barcelona uses a different architecture, which is much worse in floating point calculations. It is only more power efficient.

In almost every test, a dual core opteron processor from AMD will beat out a quad core amd processor. Their quad core processors were a fail, which is why I am not recommending their quad's, but their dual cores.

that said, your original point has been disproven. your "quad dual core system" will not "annihilate any 8 core xeon system".

teraflop/petaflop XXX numbers dont represent much besides raw FP.

 

No, I have four dual cores, not two quad's.
the dual core opterons are actually faster than the quad core's since this was AMd's first quad core line, and it was actually slower than the dual cores, since it had cpu allocation issues, and low clock speeds. The 3.0 dual core opteron processors do not have this problem, since they are designed and proven.
If you have an 8 core xeon system, made up of two quad cores or four dual cores, it will be slower, cince opterons are faster per clock in cpu intensive environments than the xeon's. I am talking aboiut the dual core amd's.
However, if you had four intel quad's on a single board than it will be faster, but I am keeping teh comparison in power with the same number of cores.

The intel system will be more power efficient and it will run cooler, however, xeon processors need expensive fb-dimms, so watch out. Most standard ddr2 ecc memory will work with teh opteron line, which is much cheaper than fb-dimms.

read the first line again. and read my post...

your statement "if you have an 8 core xeon system....." is incorrect. if whatever application you are running is multi-thread optimized, then it will take advantage of all cores. clock for clock, intel is faster. as well, just becuase the AMD is "3.0 ghz" and the equivalent intel processor is "2.4 ghz" doesnt mean the AMD is faster because it has "0.6 ghz", "more".

RETURNING to Squidman's question, yes, there is great potential for GPGPU applications. look up FASTRA, its a (norwegian?) few thousand euro "gaming" machine with 9800gx2s and it outperforms a multi-million supercomputer, for computer assisted tomography.
