After reading your poorly written BS without facts, data and logical explanations and my nick-name in the same post, it is my pleasure to respond. I don't believe that I can change your blind fanboyism about your favorite company, nor I think that you'll learn something. But its kind of fun to frustrate people like you.

is it my fault you're always full of BS,and sorry english is only my third language....

It is not the RAM that provides bandwidth, but it is the memory controller(s). For example K10 with DDR2-667 provides more bandwidth than K8 with DDR2-1000.
Memory bandwidth is not CPU performance. It can help in certain cases, but until we have a proof(backed up with DATA) we can't conclude anything.
The fact that K10 has two optimized(each much more advanced than the one on the K8) memory controllers and a shared L3(which all can be dedicated to a single core if needed) leads to the conclusion that K10 should perform well even with the high latency rDDR2-667.
In a case you didn't know, the cache memory reduces the impact of the RAM latency and bandwidth(i.e. Core2).

So anyone with some basic knowledge about CPU architectures won't expect a dramatical performance improvements from a faster RAM.

i have basic knowledge about cpu architectures
indeed,we need proof backe up with data,so proof me there is no bandwidth difference between DDR2 667 ECC and DDR2 1066 on K10...

Then you must be blind. When you are talking about performance in 2P environment, the clear winner is Clovertown(X5365). You can cry as loud as you want about the clock advantage it has, but it is almost a year old CPU and blows away the Opteron 2350.
What makes the Opteron 2350 attractive is:
1) the overall system energy efficiency
2) overall system price
Thats why it will gain some market share for AMD. Those who are looking for a TOP performance are looking at Intel.
No matter how hard AMD tries with their K10 barely reaching Core2 IPC and their 65nm SOI they are not going to come close to the performance crown in 1P and 2P.

i was talking about 2GHz barcelona vs 2.33 ghz Clover,and there is no clear winner there...

It is VERY important for AMD, but not for the mobile/desktop/workstation/server markets. Quadcores already exist for many years, and if you talk about x86 Intel have sold millions already.
If no body buys them, then no body will produce them. So, there are people and companies who need the best performance and are willing to pay a premium for that.

so you say quadcore isnt important for the server market??

Yes! AMD needs money or it'll die sooner than most people here expect. When AMD will make some profits and pay off the loans, we can say that they are saved from the disaster. Until then, we can only hope they survive.

Sufficient to compete in 2P and 4P environment until Nehalem.

Don't be surprised if AMD paper-launch the parts you hope to arrive soon.

so you have crystall ball and knows how nehalem will perform?
