silly question??

[anikhtos]

here is my question
is it or not
dual channel configuration vs single channel boosting the cpu perfomance by a few % somethign like 5-10%??
i upgrade my laptop memory to 8 gb to enable dual channel
the only one that seems to improved was the 3d perfomance
6.1 gaming perfomance for the igpu lol
that tells a lot for wei
and 4.8 for the graphics lol

No and, yes.

you wont be able to tell the difference.

more ram = always helpful

well i do not expect to feel the diferense i only ask if moving from single to dual chanell memory will benefit the cpu to score a bit better?
i thought back 10 years ago or more when they indroduse dual channel memory it has a benefit of something like 10% iver single channel the days od ddr1 if i remember correct.

going to dual channel originally was about a 15% increase overall, but now with it being assumed you have it, it will be a loss for not having it.

As to your igpu changes, a difference could be measured as the integrated gpu's generally use system ram so more bandwidth will be noticed. With other applications, it depends on it's use as even a single channel of ddr3 is quite fast.

iGPU's love more memory bandwidth as they are constrained. So having dual channel will certainly help over single channel.

As for CPU performance, you would only notice it in very heavy memory related task.

WEi is useless

if you run Super Pi, you'll see the difference (had to build a 2500k using single channel 2x4gb b/c of the case and hsf limitations... the Super Pi timing were definitely slower than someone else running the equivalent frequency with dual channel)

The benefits are about the same, though sometimes better. The thing is, you need an application that can use more bandwidth, and/or more IOps to benefit. Any GPU-heavy app will qualify, with the IGP.

Your CPU hasn't gotten any faster, it's just been given more breathing room.

Typically single -> dual channel yields more like 3-4% improvement and only in memory-intensive tasks (like certain benchmarks). Virtually unnoticeable in daily use.

Doubling the memory might have perceptible results but only if you actually use the memory. Most people are still just fine with 4GB.
