NVIDIA Tegra K1 Kepler GPU

NVIDIA GeForce ULP K1 (Tegra K1 Kepler GPU)

The NVIDIA Tegra K1 Kepler GPU (successor of the GeForce ULP series) is the integrated graphics card in the Tegra K1 (formerly known as Tegra 5). Compared to its predecessor, the GeForce ULP, it made the move to a unified shader architecture. It integrates a full-featured Kepler-based graphics card that includes a single SMX with 192 CUDA cores clocked at up to 950 MHz, 8 TMUs and 4 ROPs. Therefore, Tegra K1 offers about half the power of a GK208 chip (384 shaders, 32 TMUs, 8 ROPs) such as a GeForce GT 730M or 740M. This is a big step forward compared to the GeForce ULP in the Tegra 4 SoC, which was based on an old architecture with dedicated pixel- and vertex shaders that is similar to the GeForce 6 series of 2004 and supported only OpenGL ES 2.0. The new graphics card supports OpenGL 4.4 and DirectX 11 in hardware, or well above the current OpenGL ES 3.0 standard that is most common amongst the majority of mobile operating systems. Furthermore, the Kepler GPU can be used for general calculations using CUDA and OpenCL 1.2. As an example, Nvidia has shown how to perform real time video effects using the GPU and CUDA (Chimera 2).

Performance

In the 8-inch Nvidia Shield Tablet, Tegra K1 renders 66 fps in the GFXBench 2.7 T-Rex offscreen test. Compared to the competition, Nvidia's SoC is clearly faster than the Qualcomm Adreno 420 (max. 40 fps, Snapdragon 805), PowerVR GX6450 (max. 44 fps, Apple A8) and Mali-T628 MP6 (max. 31 fps, Exynos 5430). Except for the even (slightly) more powerful PowerVR GXA6850 (max. 70 fps, Apple A8X), Tegra K1 has one of the fastest mobile GPUs in late 2014. Even the most demanding games and high resolution displays are handled without any problems.

More information on the SoC and performance data on the CPU can be found on the SoC page of the Tegra K1.
