I was surprised today to launch a new EC2 instance, type m1.large (64-bit, 7.5 GB RAM), which usually runs on Opteron CPUs, but to my surprise cat /proc/cpuinfo produces:

Is Amazon moving away from Opteron-based servers? I hope so. Xeon machines so far provide better performance, so I guess they decided to expand their farm with those. Great move!
I could not find any confirmation or other reports on the subject, so please confirm!

Nevertheless, aren't they virtualized processors?

No, processors are real. But apparently capped in some configs.
Never mind. I guess we are staying in SoftLayer — "talking to metal" is much more effective for us. Virtualization still introduces high penalty for DBs.
