I have seen the specs and have deployed both products. One is a dual core 1GHz PPC proc, the other uses a 36 core TILE processor at 1.2GHz. Not exactly apples to apples. The performance show in the "Performance Test Results" not only doesn't equate to "about 10 times more PPS" (depending on the test, sometimes up to ~17x increase), but also doesn't consider the fact that it's an "All Ports" test. With the CCRs dedicating a core (at least) per port, it's not an identical comparison.
If you consider all 13 ports on an 1100AHx2 are shared between 2 cores, and just assume that the 12 ports on that model CCR are using 12 TILE cores (and no more), then you end up with a 2.84x increase in per-core PPS performance BEST CASE (with FastPath). If you look at the overall system best case (fastpath), of course you have a 17x increase in kpps performance "as a system". Worst case however, you find a 5.35x increase in system performance. A huge improvement, to be sure, but the TILE processor package can be very deceiving depending on the context of the evaluation.
