3GB, 6GB or 12GB Investigated

Gaming Benchmarks

Crysis is without doubt one of the most visually stunning and hardware-challenging games to date. By using CrysisBench - a tool developed independently of Crysis - we performed a total of 5 timedemo benchmarks using a GPU-intensive pre-recorded demo. To ensure the most accurate results, the highest and lowest benchmark scores were then removed and an average calculated from the remaining three.


Call of Duty 4 is a stunning DirectX 9.0c based game that really looks awesome and has a very full feature set. With lots of advanced lighting, smoke and water effects, the game has excellent explosions along with fast game play. Using the in-built Call Of Duty features, a 10-minute long game play demo was recorded and replayed on each of the GPU's using the /timedemo command a total of 5 times. The highest and lowest FPS results were then removed, with an average being calculated from the remaining 3 results.


Ubisoft has developed a new engine specifically for Far Cry 2, called Dunia, meaning "world", "earth" or "living" in Parsi. The engine takes advantage of multi-core processors as well as multiple processors and supports DirectX 9 as well as DirectX 10. Running the Far Cry 2 benchmark tool the test was run 5 times with the highest and lowest scores being omitted and the average calculated from the remaining 3.

Results Analysis

As we saw in the synthetic benchmarks, there really is nothing to choose between the 3 kits. Greater capacity adds such a small amount it would be fruitless buying more ram for gaming alone, especially if you already have a 6GB kit. I tried each kit for a night's worth of gaming and while I did not benchmark them, the 3GB kit seemed to lag a little and was noticably slower in level loading. The 6GB and 12GB kits were indistinguishable in game but the 12GB kit did seem to be snappier in the level loading stakes but not as much as the jump from 3GB to 6GB.

Let's take a look at the kits overall performance...

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
