Will DDR RAM be of great advantage on an 800/850 MHz CPU compared to normal SDR RAM???

well... anyone knows???(or thinks?)

anyone...????

it won't be that great, maybe %5-10 increase it's not going to be double if that's what your asking. but that's my opinion.

 

[Lombardaga]

yeah, it would be bout 20 % or something ive read, but i dont know what kind of system they had in mind when saying this figure...
So on an 800-850Mhz T-bird the advantage wouldn't be more than 5%??? Anyone else have somthing to say bout this....???

 

[Howard]

I heard up to 40%.

The true answer is "it depends on the application." Anyone who is an RC5 cracker will see virtually no improvement at all between SDR and DDR. Someone who is doing something like Divx encoding might see as high as a 30% improvement. In a way, the application/benchmarks where you should expect to see a sizeable improvement improvement should be similar to those tthat see a large improvement with Rambus Direct RDRAM as compared to SDRAM. The latency of DDR is not improved of SDR , but the bandwidth is greatly improved. So applications that require a lot of bandwidth should see an improvement, while those whose data and code are contained in their entirety in the cache should see little to no improvement.

Anandtech did a preview of DDR. This should give you some idea of what to expect.

I think it would depend on what type of applications you're running. You'd only see a large performance increase in applications that stressed system bandwidth. 🙂

the thing is if its worth waiting for....
is it so that i should have at least a 1 GHz CPU to get a lot of benefit from the DDR?? After all, i have to wait some time to get it, and YES it will be more expensive than a regular SDR RAM and SDR mobo combo, cuz the mobo will be as high as $200 and the shops want some extra money on new products as well...New revolutionary technology tend to be just around the corner all the time, so is this tech worth waiting for???

 

[Lombardaga]

Well, so how bout games for instance???
would that be of great improvement w/ DDR??

Quake 3 will see a pretty good improvement (~10% I think), becuase the data going through the FSB to the Video card can get to it's destination faster (usually it goes through the system RAM, unless you have Fast writes enabled, however)... however, becuase Fast Writes isn't quite that efficient yet (for some reason or another), you normally don't see much of an improvement.

this is how I can explain the Pentium 4's increase (it has a nice FSB, and pretty good SDRAM bandwidth), even though the FPU, isn't better then a P3.

and thats with 800-850 MHz T-bird u r referring to????
Cuz it would be a shame to buy the DDR RAM if your processor speed have minimum benefit of it...I am i gamer though, so...
