yb,

1. socket 939 comes in Q104?
That is the expectation. AMD will update the official roadmap on November 6.

2. s. 939 will use unregistered DDR, unlike sock 940?
Yes

3. it will be dual-channel?
Yes

4. it will not support SMP?
I am not sure about that. Most likely, it will not support SMP, unless AMD wants to at some point abandon Socket 940 and move entirely to Socket 939, which I don't see as likely.

5. because of #3 sock 939 will be much faster (10-15%) than sock 734 on same frequency?
On apps that like a lot of bandwidth

6. because of #2 it will be much faster than sock 940 on same frequency?
On apps that like low latency (high percentage of apps). Sum of 5 + 6 = Socket 939 will never be slower than either Socket 754 or Socket 940 CPU.

7. 256K cache will come together with sock 939?
Those issues are independent of each other. I would expect 256K chips mostly on Socket 754

8. 256K cache sock 939 is approximately as fast as 1M cache sock 734?
Too many variables to give a reasonable answer.
