The Jetson TK1 SOC

The Tegra K1 SOC in the Jetson TK1 is targeted for embedded GPGPU applications as well as general purpose use in power-constrained devices such as super-phones, tablets, laptops, set-top boxes, and low-power desktop computers.

Competitive Positioning

The Tegra K1 SOC GPU provides both excellent graphics and GPGPU performance. The GPGPU capability is probably greatest competitive advantage. Nvidia claims Tegra TK1 can attain 326 GFLOPS, whereas its closest contemporary competitor, the SnapDragon 805, may achieve estimated 200 GFLOPS. Imagination Technologies announced a PowerVR GX6650 which favors FP16 operations. At best it might be competitive with the Tegra K1 in GPGPU. However, it had not yet been sampled or bench marked, and may not ship until 2015.

NVidia have a strong ecosystem and experience in the GPGPU space. NVidia leapt over the competition by using the same Kepler GPU architecture that is used to power desktop GPUs and many of the worlds fastest super computers. This allows them to leverage existing (and well-tested!) code to provide superior breadth of capabilities, including OpenGL ES 3.0, CUDA 6, OpenCL 1.2, OpenGL 4.4, and a bevy of other GPGPU tools

Power Consumption

According to my testing, graphics performance on the Jeston TK1 is about on par with Intel HD 4600 graphics, but with superior OpenGL and GPGPU capabilities. Power draw for graphic-intensive tasks has been surprisingly low. It appears that typical graphical applications probably default to lower-power FP16 operations. GPGPU tasks, by comparison, do increase power draw significantly.
