    "So currently Barts is arranged in 2 rows of 7 SIMDs - each SIMD has 16 x 5 = 80 SP's

    Likewise, Cypress XT is arranged in 2 rows of 10 SIMDs - again, each having 16 x 5 = 80 SP's

    It appears that Cayman may very well be arranged in 6 modules - each with 1 row of 5 SIMDs - each SIMD is 16 x 4 = 64 SP's, thus giving each module 320 SP's and thus an overall setup of 1920SP's. Cayman PRO may thus have 1 SIMD in each module disabled, thus creating 6 x 4 SIMDs for 1536 SP's total

    And for the third point, it appears that TMUs are no longer tied to each row of SIMD, and thus they can be shared - that is, disabling SIMDs doesn't disable TMUs.

    More interestingly, it appears that Tesselation will be tied to each module, and going from 2 engines to 6 should mean a significant boost in performance "
