3GB, 6GB or 12GB Investigated

Encoding and compression benchmarks

 
ViMark is designed to take the inaccuracies and guesswork out of measuring the time taken to encode video files, ViMark produces easily comparable and consistent results for encoding raw video into Windows Media, Quicktime, and Gif formats. As always, a total of 5 benchmark runs were performed with the highest and lowest scores removed and an average calculated from the remaining 3 scores.
 





 
 
7-Zip is an open source Winzip-style file compression utility that has the ability to compress and decompress many file formats including its own .7z compression scheme. 7-Zip also comes complete with its own benchmarking utility for gauging the compression and decompression speed of the system that it is installed on.
  



 
 Daniusoft

Daniusoft DVD Ripper provides powerful and easy-to-use DVD Ripper software which could ripping DVD to MPEG and almost all video and audio formats format with fast conversion speed. We converted a DVD to AVI format 3 times using this tool and then took the average from those times.
 
 
 
Results Observations

One area in which I expected to see dramatic differences in the capacity of the kits on test was video encoding. ViMark showed there's virtually no difference at all between 3GB, 6GB and 12GB which was hard to swallow. To gain a little more perspective and rather than using a synthetic benchmark, I decided to encode a DVD (StarWars:Attack of the Clones) converting the movie to AVI format. I ran the encoding process three times per kit just to be sure and the results gave a better, more informed picture however, the difference is still not as large as I would have thought.

Let's move on to our 3D Benchmarks...

Lol at the photos with all the ram. And 200 quid for 12GB, I paid that for 6GB 1333MHz. Prices are really dropping now.

Nice and unique review, really sheds some light on questions which are asked a lot and answered rarely.Quote

That was a really good review - I really enjoyed reading that.

I want to have enough RAM to take photos like that though. Quote

Outstanding article.

The large leap in the price from 6g to 12g as opposed to the leap from 3g to 6g really pushes the business requirements for the largest kit. The CS4 results show they'll get reward for it professionally in terms of time over work hours. Even tho 6g will do a great job, 12g plus the cost, minus perhaps the vat and time saved would make it viable.

(*cough* most of ours still use 2g in the main, with 4g if they're lucky - don't know of any 8g machines - 775 ofc) If the heads of the departments concerned really had their heads around the figures, they'd be more concerned with maxing the memory of their pcs rather than paying over the odds for a retailed pc with an nvidiafx card that will relatively not help them as much. Go figure.

From what I can see as far as the gamer is concerned, 3g is no issue, particularly for those who fps the majority of the time. I'd perhaps throw in an argument of certain games utilizing more memory over others. 6g for £95 or so in the present climate is surprizingly cheap, meaning I expected it to cost a whole lot more.

I think it will get to a stage where 6g is so cheap that considering u've spent 100s on ur mobo and cpu, a matter of 10s of pounds between 3 and 6 would make it a non-issue and covers more bases.

I'm glad u did an OS reinstall between memory switches, there would have been many complications otherwize.

Great stuff.Quote

Cheers for the comments guys.

This was perhaps the biggest, most time consuming article/review I have done thus far. As we have not done a test on this magnetude to date, a lot of experimentation was used to find the optimum testing procedures, image and video sizes etc because, as you say Rast, without a re-install, there were anomolies and strange results that didn't match what I was expecting. Not only that but passing filters over a 4gb image with 3GB of ram ground the system to a halt whereas 12 GB found it a breeze, if somewhat time consuming.

I used each kit for a week's worth of 'everyday' computing. 12GB is definately worth it if you are working with large files and although most of the benchmarks don't significantly back this up, simply opening and closing programs, general vista use etc made the expereince so 'slick'.Quote

If u still have the 12g in-house, it'd be interesting if u could create a ram disk and run a game off it. Dunno how u'd do that with Vista.Quote
