not a big difference for amd but the cas matters most of the time

For reference, DDR2-800Mhz is half of DDR3-1600Mhz, which means 800Mhz 4-4-4 would about equal 1600 8-8-8 in actual performance. Most 800Mhz generic kits are sold at 5-5-5 or the much worse 6-6-6 (with high end kits taking on 4-4-4; it's rare to find a kit that can do 800 3-3-3), and most 1600Mhz kits are sold at 9-9-9 or 8-8-8 (higher end kits are often sold at/capable of 7-8-7 or 6-8-6; the absolute highest end kits can do 1600 6-6-6).

The effective, real-world performance difference is not earth-shattering.

However, I suspect the i7 processors that use triple channel get a greater performance advantage than the benchmarks above show (simply due to dual channel vs triple channel and less due to the speeds, cas, and timings).

1. Intel platform
2. Where are the timings?
I can't tell anything from this sadly

On the AMD platform the results are about the same (second link gets into the timings).
A huge performance advantage of an astounding 1.84 frames.
Its not exactly what he is asking about (but it is close). I can only imagine the gap would be around 2.84 frames at the most between 800 and 1600.

However, I'd guess that the i7 9xx, which actually have triple channel, would have a greater advantage than these benchmarks. Yes, I know the i7 is not AMD platform.

My point is that the DDR3 performance advantage is not earth-shattering. If AMD (consumer-wise) had a triple channel-capable CPU and platform it would be more significant. As far as I know, they don't.

Triple channel is only about 5% boost on ram performance over dual channel, so no big performance gain and not worth the money.
