perf diff between DDR2 and DDR3

[razorseal]

is there a big perf gain between a DDR2 and a DDR3 system?

[Evilsizer]

depends on the speed comparsion... as ddr3 is able to achive much higher speeds then ddr2. right now based on price ddr3 needs a bit more time...

2nd but if u look how much it has come down it has come down a lot. I mean the price of DDR2 is 1/3 of the price it was 1 1/2 years ago.

performance increase ~ 10-20%

price increase ~ 150-300%

Rough averages. You can buy a really good overclocking set of DDR2 for ~75$, a good set of DDR3 is over 200$. (2x1GB)

Yep and by the time ddr3 price drop here comes ddr4 hehe.

I wanna know why they can't use GDDR5 for regular machines :p ATI's new card is supposedly gonna run at 3870mhz effective on GDDR5.. True 1:1 CPU/RAM ratio :drool:

I did some comparitive runs with similiar systems :

where do you get numbers like that from? a blanket statement like this shows you really have no idea and basing your reply on what you have read and not tested.

seriously, there isn't a lick of difference. yes, bandwidth in Everest is a lot higher, SPi 32M runs a good bit quicker because of the extra bandwidth, but in everyday stuff...the performance gain is minimal to none. you get more of a boost lowering tRD one level on Intel based motherboards than you do going from high end DDR2 to high end DDR3.

there are some bandwidth intensive programs that would benefit from the higher bandwidth, perhaps 3D rendering, crunching or the like. but for 90% of the programs most users are going to be running, especially games, DDR3 offers absolutely no performance gains. even in encoding and converting, there is very little gains to be had. and i am talking comparing DDR2-1000 4-4-4 to DDR3-1800 7-7-7 not some of the crappy low end DDR3.

my opinion is based off of testing dozens of DDR2 and dozens of DDR3 kits on multiple platforms. for benchmarking, DDR3 is key, for actual computing...just another evolution with very little benefit...like all of these Intel chipsets coming out one after the other, but that is a rant for another time. this industry is just a cash grab and we are all suckers for it...hell, i help promote it :bang head

Hmm they can't use gddr5 prolly cause ddr4 ain't being sold anywhere yet?

[jjw0782]

Oh ya there isn't really much of an increase going from ddr2 - ddr 3. Not worth the upgrade. Just my 2 cents.

[JamesXP]

Keep your 2cents in one post, double posting is pretty much frowned upon here at OCF.

but yes, performance increase is minimal.

Uhh, sure it is. We're about a month away from cards with GDDR5 even..

Performance difference in games between DDR21066 at 5-5-5 and DDR3 at 1333 7-7-7 ddr2 performs better by 1-3%

There is a write up over at Tom's on DDR3 but they did not test anything faster then 1333. As it was not "economically feasible" for the average enthusiast

(I am looking for the article now, I found it by accident the other day.. )
