Multicore, OOO, superscalar (2), speculative. Looks like it tops out at 1.5 GHz. I count 8 pipestages.
ARM is deeply, deeply attached to Dhrystone scores, of all things. It's hard to translate that into real perf.
It's even harder to tell what their general FP perf is, but it mostly doesn't matter since they have NEON (sorta like SSE+MMX) for client math acceleration.
They also have a "GPU"; no idea what that means. Interestingly, it is labeled as "coherent".
Single core is 250mW TDP; not sure at what frequency. I've seen some idle power graphs but no actual numbers.
1.5 mm^2 on 65nm? Not really a meaningful number without some sense of frequency, cache, add-ons (like FP). Damn IP companies. However, my guess is it is a low frequency design target sans cache, NEON, FPU, etc.
