That is ridiculous, First, the Amd cpu comes with memory controller integrated into CPU to lower the cost of manfunaturing, Second, Amd CPU has be to tweaked to go higher clock frequencies to take advantage of more memory bandwidth.
You're a little out-of-date as regards Intel. The Nehalem and Sandy Bridge CPUs have integrated memory controllers, similar to what AMD has been doing for years. Synthetic benchmarks (such as Core i5 2500K and Core i7 2600K review) show that the high-end Intel CPUs have better memory performance than AMD's finest. I doubt that the real-world differences are that large.

The price/performance trade is more complex. Most of the budget gaming system guides I've seen in the past year or so use AMD CPUs.
Well, There's an interesting of AMD is going with T-RAM technology is coming soon as AMD produces the 32nm die or less size of die processor chips with newer T-RAM technology will be in use, it is really interesting in AMD development.

Try out CPU-Z it's free and will also give your RAM info.
There is also a GPU-Z for graphics card info.

Overall, yes; however, there are some apps and games that do take advantage of faster RAM. Sure, sometimes fps gains are insignificant, like 2 or 3 fps, but sometimes the fps difference is 10 or 20, which isn't insignificant at all.

Actually I have several programs like CPU-Z:
  • CPUID HWMonitor
  • Hardwaremania BlackBox
  • Windows System Information Tool
I think that HWMonitor or BlackBox has a benchmark tool (goes to check ...).
