Re: 1 teraflops, 10 watts
This is one half of a teraflop as we know it. NVIDIA's slick marketing got them a slick headline. It's also called "Erista" not "Arista".
NVIDIA CES 2015 Press Conference Liveblog
"11:12PM EST - Confirmed that it's Erista
11:12PM EST - NVIDIA is proclaiming it a 1 TFLOPS GPU, though this is at FP16 as opposed to the more normal FP32 metric for TFLOPS"
