Quad channel DDR4 does not help performance at all in real world.

What about IGP performance with quad channel ram?

Even if such a thing existed, who would purchase an expensive -E platform just to run a slideshow on an iGPU?

This is why Iris performance is equally nonsensical - nobody buys a $366 CPU to play games on something slower than a GT740. At least with AMD you're paying peanuts for that slideshow.

3 older games tested is hardly conclusive.

There are memory-intensive applications that can effectively utilise the increased bandwidth. IGP (integrated graphics on your CPU) is one of them, but also more common setups such as a ZFS server would utilise memory bandwidth effectively.

Those benchmarks posted in the review are simple number crunching, and memory performance will not impact those workloads significantly at all. That is nothing new - that was the case back in the early days with DDR1 and DDR2. Nothing new -- walk along...

Its true it will help with a IGP...but if I want more graphics horsepower it seems silly to spend a lot of money on fast ram in an effort to improve an IGP performance from garbage to crap level. Why not just buy a discrete card instead?

Never understood the performance RAM craze. It used to give you more overclocking options with the multiplier game but is that even a consideration anymore? I lost interest in overclocking so I don't know. If you want more performance take the money you were going to spend on cheap ram and use it on the CPU, SSD, Video card...anything really.

I like lots of RAM but generally I just buy whatever is cheap and has a lifetime warranty.

Go run a server hosting 8 different VMs, and tell me how quad channel memory doesn't make a difference.

It's useless for consumer workloads, but that's because "Haswell-E" is just a repurposed server CPU.

Real world you wont tell a difference. Benchmarks you will see a difference. But who wants to run benchies all day all.. Go play your favorite game go play other games, Do something positive with the rig instead of benchmarking and throttling the poor comp.
