What is the real world difference between DDR2 and DDR3?

post #1 of 10
Thread Starter 
and what sort of performance increase in gaming is there?

A quick google search says theres not much, but I'm not convinced.

To be honest, I don't think there's much difference, when I upgraded my system, I also upgraded my CPU and all other parts so I can't say for sure.
Back when DDR3 came I didn't get it because supposedly the performance increase was anywhere from 0% to 2% or so.
People still roll with DDR2 and have fast systems, I don't think it's worth upgrading to DDR3, unless you plan on buying a whole new system or if you need a new motherboard.

The difference is probably noticeable at the highest speeds. Also the price used to be DDR3 was crazy and DDR2 was cheap not any more.

^Exactly

Not worth basing an upgrade around, although if you are replacing a motherboard, just go with the flow

Edit: Not reference the above post, the one above that one

Around 2%. Nothing mind-boggling.

If you can use DDR3, there's little reason not to. If you're thinking of swapping/going with a DDR3 motherboard for, say, a Core 2 platform, again, it might be worthwhile since DDR3 is cheaper now, but DDR3 offers practically no performance benefit for Core 2, so it's not worth getting if you already have the DDR2 motherboard/DDR2 RAM.

I'm not sure for AMD.

If your building a new system your not going to use DDR2 anymore, people like me with an overclocked Q6600 still get great performance though. I'm holding out till we get 8 core CPU's that will completely blow away my old system.

Thanks for that guys

But do actual clock speeds and timings make a difference?

Higher clocks increase the read/write speed on on the RAM chips, this increase performance, but not like double the performance of something

The "good" timings for DDR3 are different from DDR2, but beyond that DDR2 and DDR3 really are quite similar.
