[CGUYS] Processor speed for video work

2007-09-19 Thread Steve Rigby
A friend of mine is looking into a new computer for video work. I am guessing she is making videos of some sort, probably high resolution stuff, and is seeking something that runs at 2.66 GHz or faster. I guess that faster is always better for video, but would she truly require that fast a

While one cannot say more cpu power hurts, a good editor and a cheap cpu can do the same, it just takes longer to render. As long as it finishes overnight, I really don't care. Video is one of the vertical markets Macs enjoy (along with publishing), but I personally feel the system is very limitin

One thing you may be forgetting is dual-processor computers. Even the low-end (2.0 GHz) iMac is dual-processor with 1 GB of RAM, 250 GB HDD, 8X DVD (Superdrive) and ATI Radion HD 2400 XT video card (128 MB RAM), as a starting point. She can certainly try one in an Apple store. She can probably a

The speed cuts back on the processing time. The faster the processor the faster it gets done. Dual core's are usually much faster with a slightly lower speed. I upgraded this year from an AMD XP2000+ to a dual core Opteron 157(?) which is a 2.01 GHZ with 1 MB cache. I cut my processing time

This isn't true as written. If it takes you 2 hours to edit a project now, it will STILL take you 2 hours to edit the project even with that super-duper new whiz bang computer. Total time saved: ZERO. You mention a rendering speed increase of 8X. While that may be true for some people, most won't

If "high resolution stuff" means high definition, then bigger and faster is a must. The storage requirements for high definition are a lot more than for standard def, as is the processing power. "Amateur level video work" doesn't mean that a decent level of processing/storage won't be needed. H

Increases of processor speed increase processing not mathematically but algebraically. (I may have the terms wrong but it is not 2+2+2, it is 2x2x2) Notice I only upgraded from a 2000+ to a 2.01 but it was a larger cache and a doubling of the processor. Any dual core will increase the speed

Proc speed isn't the only thing you would want for a video editing machine. 2 to 3 gigs of RAM would be good for one. And processing speed isn't completely determined by the processor. The motherboard chipset/ bus is also an important factor. All you need to know about that is for sales rea

Apple uses the same Intel chips that many PC's use, so the same economies should apply in that respect. Rev. Stewart Marshall wrote: I do not know about Apple Computers, but in the IBM realm the price decrease on Dual processors has been steep. **

Good points - amount of RAM, bus speeds and other design factors do play their roles in determining performance. I would want at least a 7200 RPM HDD too (even faster are the 10K and 15K) connected via SAS or at the least, SATA. The issues described would also apply to a Mac Pro workstation (desk

Any new iMac, Mini or MacBook, dual core, will be fine. My new MacBook has so much more power than my old G4, but I used that "old" Mac to create and edit dozens of movies, using several different programs--yes you DO have good choices, including open source like Jahshaka, free iMovie/iDVD--you

Did I say anything about Dual cores in what I wrote? Typically when you are increasing processor speed a number of things are happening which increase your speed more than just a mere multiple of the processor clock speed. when you go from say a 1.5 to a 3.0 you are not merely just doubling

Many factors affect how much increase in efficiency you can realize by multiple core or multiple processors. In a design with good infrastructure (such as a good server), you may get up to .85 times faster processing with two processors versus one, especially in a 64-bit design with plenty of memo

Actually, we're straying off topic here, but a few direct observations specifically about video rendering... Multiplying CPU cores *directly* multiplies rendering speed. ie, turn off one core, you render at 1/2 the speed. Not a fraction, but exactly double if all else is equal. Of course, when yo

in a cheep pc, the processor is at least 25%(retail) of the cost of the machine. in an iMac, it is probably under 10%(retail) cost of the machine. even 50% reduction cost of chip will have but small effect on iMac. At 01:23 PM 9/19/2007, you wrote: >Apple uses the same Intel chips that many PC'
