What "real-world usage" are you talking about, specifically?
EDIT: looking at your comment history, you seem to be focused on VFX tasks, which tend to be entirely bound by memory hierarchy; even on x86 the FPU spends most of its time waiting for data. For a workload like that, you absolutely want to buy the beefiest cache/memory system you can, but that shouldn’t be confused with a processor being more competitive “flops-wise".
I don't know why u guys are arguing, he wouldn't have much use this ARM part. Where this will excel is in CRUD web apps. The ARM part it there just to shuttle data between the 10Ge and the 128GB of ram.
