Looks like Z-01 replaces the whole 9W C-range (Z-01 is identical to C-50 in every way, but TDP got down from 9W to 5.9W). It's already on production (some shipping Win7 tablets are using it). And Trinity at 17W basically invalidates the whole 18W E-range. It's very interesting to see how the 17W Trinity compares to the 17W i7 3667U Ivy Bridge. 3667U CPU turbos up to 3.0 GHz, so Intel is going to keep the single thread performance crown easily, but Trinity could beat it in four thread performance, and it has likely a slightly faster GPU as well (but Ivy's new GPU isn't that bad either, so Intel is going to offer at least some competition in that area as well).
~1:30 in Youtube video: "50% more compute capability at almost half the power".
Indeed. And Llano couldn't really achieve very impressive clocks at 35W (1.6Ghz non-turbo, 2.5Ghz Turbo), you'd think for two-module Trinity to make sense they'd need similar clocks (well if base clock is a bit lower that would be ok as long as it can turbo up in enough situations).
Of course, but in the long run Brazos seems to be fading away. There has been basically no progress in one year now (0.05 GHz overclock with E450, and another 0.05 GHz coming up later this year). Z-01 at 5.9W (1/3 of Brazos TDP) is not that far behind in performance (and is really cheap to produce), and Trinity offers much better performance at same TDP. If either the Z-01 is scaled up or Trinity is scaled down (single module version would be considerably cheaper to produce and wouldn't likely need agressive cherry picking to reach 17W), there would not be much room left for Brazos anymore. Too bad Deccan, Wichita and Krishna all got canned (28 nm would have made the E-series much more competitive in the long run).
