But being able to playback video at that resolution has benefits for emerging technologies, like virtual reality, which can improve dramatically by playing ever-higher resolution at speeds that offer smooth and seamless framerates for up-close and personal viewing.Ī side-by-side demo of what the Tegra X1 can handle vs. 60fps is especially important to action and sports content, and to video games of course. The work that Nvidia is doing on mobile graphics and chipsets has tremendous impact in terms of potential for Netflix, as well as other content providers that are pushing the boundaries with streaming 4K video. A8X energy efficiency – X1 is the blue line. the K1 architecture, and about 1.7x the performance of the A8X on average for the same power consumption. But perhaps its most impressive performance improvements over comparable chipsets revolve around energy efficiency: The X1 offers about twice the performance as you increase power draw vs. Nvidia’s own tests with the X1 show it performing at just about twice the rate of the Tegra K1 when it comes to 1080p offscreen performance, about 1.5x in 3Dmark 1.3 Icestorm Unlimited and almost twice the iPad Air 2 in the same metric, and about 1.5x in the BasemarkX 1.1 vs. Nvidia obliged us with just such a test, using a range of benchmarks to illustrate exactly how it compares not only to the iPad, but to the current, Tegra K1-powered Nvidia Shield Tablet, which owns the graphics performance crown among Android slates. Like the Apple-designed A8X, it uses a 20nm process, which means it’s fairly easy to benchmark it against the Apple tablet in a straight-up graphics benchmark comparison. GFXBench 2.X1 features a 265-core Maxwell GPU, an 8-core 64-bit ARM CPU and can handle 60fps 4K UHD video playback in either H.265 or VP9 coding. Similar to the Apple A8X, the Tegra X1 is manufactured in 20nm. As the Tegra K1, the X1 will be most likely seen in tablets with good cooling solutions. Therefore, Tegra X1 based smartphones are unlikely. The power consumption of the whole SoC should be rather big compared to other ARM based SoCs. The integrated dual ISP is able to drive up to 6 cameras (max. Thanks to HDMI 2.0 support, the 4K60 material can be transmitted to external displays (2 displays in parallel at max). The improved video part of the SoC is able to en- and decode 4K videos in H.265 according to Nvidia (decoding at 60fps, encoding at 30fps). Therefore, the X1 should be the fastest GPU for Android based devices that should not struggle with high end Android games in high resolutions. The memory interface offers a maximum bandwidth of 25.6 GB/s (2x 32 Bit LPDDR4-3200).įirst benchmarks of the Tegra X1 graphics card using GLBench show twice as high scores as the PowerVR GXA6850 in the Apple A8X. The GPU offers 256 shader cores (2 SMMs) and clocks at up to 1000 MHz. It offers the same features as the laptop and desktop Maxwell based products like OpenGL 4.5, CUDA 6.0, OpenGL ES 3.1 and DirectX 11.2. It is the successor of the Tegra K1 GPU and based on the Maxwell architecture. The NVIDIA Tegra X1 Maxwell GPU is an integrated graphics card in the NVIDIA Tegra X1 SoC for (mostly Android based) tablets. NVIDIA Tegra X1 Maxwell GPU ► remove from comparison
