No that is not a typo, it reads TitanXp, so basically the GTX 1080 Ti release obliterated the Titan X sales right, but the GP102 GPU has more shader processors available. You now have guessed it, we're going full circle. The Nvidia TitanXp is GP102 GPU with the full 3840 shader processors enabled .
The new Titan Xp finally features a full-fat Pascal GP102 GPU, with all 3,840 CUDA slash shader processor cores unlocked. Last year's Titan X and the recently released GTX 1080 Ti only have 3,584. Titan Xp thus has 3840 shader cores, that's 7% more compared to the TitanX, which it will replace. The card is tied towards 12GB GDDR5X of memory at a full 384bit memory bus. At a 11.4 Ghz effective data-rate it offers 548 GB/s memory bandwidth (coming from 484 GB/s). Titan Xp thus offers 3840 12 TFLOPS of theoretical throughput. The card has the same 250W thermal envelope as its predecessor.
The Nvidia TitanXp also has a faster GPU boost clock coming from 1,531MHz towards 1,582MHz. The price for the new card is 1.349 euro.
