"Do you think it's possible that in fact Opteron has 2 Mb of cache, but 1/2 is turned off the same way old Celeron had the cache partially disabled?"

You are asking me if I believe AMD made the Opteron nearly twice as large as it needs to be - and twice the cost to produce - and then crippled it by using only half the available L2 cache.
The answer is no.
Do you believe such a fairy tale?
