Though I actually already added these numbers into our 1080 review yesterday, apparently today it is news. Nvidia posted specs and these now include clock frequencies as well. The 8GB GDDR5 memory will run at an effective clock frequency of 8000 MHz.
The GeForce GTX 1070 has the same GP104 GPU housed on it's PCB as the 1080, however it'll be cut-down GPU with stripped away segments, it has 1920 shader processors. This means it is has 15 out of the 20 SMs active (15 streaming multi-processors x 128 shader cores). The memory is clocked at 2000 MHz actual which is 8 GHz (GDDR5-effective) at a memory bandwidth of 256 GB/s. Single-precision floating point performance at 6.45 TFLOP/s. The card will start at 379 USD with the founders edition (reference card) costing 449 USD. Below an overview of the specifications:
