With Tegra K1 and its Kepler GPU, Nvidia brings OpenGL 4.4, and not only OpenGL ES, to mobile devices, and the company is demo’ing OpenGL games such as Trine 2 on Tegra 4 reference tablet at CES 2014.
In my initial post about Tegra K1 announcement, I missed some key features about Nvidia new processor which has now popped up on their website such as support for up to 8GB RAM, 4+1 configuration, etc and so listing a summary of the technical specifications of the 32-bit version may be useful:
- GPU – 192 NVIDIA CUDA cores using Kepler architecture
- CPU – NVIDIA 4-Plus-1 Quad-Core ARM Cortex-A15 “r3” up to 2.3 GHz
- Memory – DDR3L and LPDDR3, up to 8 GB with 40-bit address extension
- Display – LCD: Up to 3840×2160, HDMI: Up to 4K (UltraHD, 4096×2160)
- Package – 23×23 FCBGA, 16×16 S-FCCSP, or 15×15 FC PoP
- Process – 28 nm
The photo of the die shows the massive area taken by the 192-core GPU (turquoise), the much smaller four Cortex A15 cores at the bottom, and the companion core (also Cortex A15?) between 2 Cortex A15 cores.
Tegra K1 reference tablet is based on the company’s Tegra Note 7 chassis, but features a 1920×1200 display, and comes with 4GB RAM instead of the 1280×800 display and 1GB RAM found in the Tegra 4 tablet. That’s probably good news Nvidia can use the same chassis, as it could mean the extra performance does not come with too much extra power consumption, and corresponding heat dissipation issues.
Other details about the tablet are currently lacking, and I could not find further information on Nvidia website.
Nvidia showed Trine 2 demo during their CES 2014 press event, but Brad Linder, Liliputing, is at the conference and shot a quick video showing more graphics effect, and what possible on Tegra K1 reference platform.
