Early benchmarks suggest NVIDIA's new Tegra chip outperforms Apple and Qualcomm
The graph above comes courtesy of Tom's Hardware and, whichever way you look it, it suggests NVIDIA is onto a good thing. The company's recently announced Tegra K1 processor combines a handful of ARM Cortex-A15 CPUs with a GPU based on the same successful Kepler graphics architecture found in desktops and laptops. The result seems to be a minimum 25 percent lead over the current generation of flagship chips, including Qualcomm's Snapdragon 800 and Apple's 64-bit A7, as measured with 3DMark -- although this may not be an especially fair comparison since we don't know the precise wattage of the Thinkvision's processor (if it's more than a few watts, it shouldn't really be compared to the chip in a smartphone). You'll find a roughly similar pattern in other tests over at the source link, but before you disappear into a new tab here's a couple more disclaimers: Firstly, these scores are based on a Lenovo Thinkvision 28 Android all-in-one (with a lovely 4K panel), which Tom's Hardware was led to believe (but not officially told) contains a K1. Secondly, assuming this is a K1, it's definitely not the 64-bit version; it's not running at NVIDIA's claimed max clock speed of 2.3GHz, and it's almost certainly not using market-ready drivers -- all of which suggests that 2014's crop of Tegra K1-powered tablets could be even more powerful than what we're seeing right now. Update: More benchmark scores are spilling out. They still only relate to graphics, and they rely on a pre-release version of GFXBench, but these numbers would suggest that a Tegra K1 reference tablet can match or even beat the 3D performance of an Intel Haswell laptop with integrated graphics, despite the latter presumably burning many more watts.
Lenovo trots out a 4K Android-powered all-in-one, with a standalone monitor to match
So Lenovo announced a whole bunch of all-in-ones, you say? You'll have to be a little more specific than that. In addition to unveiling a trio of Windows-based models, the company announced two more that run Android. These include the consumer-friendly N308 and the ThinkVision 28, a 4K machine destined for the workplace (pictured above). Starting with the consumer model (this is CES, after all), it costs a reasonable $450 and, accordingly, comes with some fairly middling specs -- notably, a 19-inch, 1,600 x 900 display and a spinning hard drive with up to 500 gigs of space. That big display aside, you're basically looking at an oversized tablet, with Android 4.2 installed and a quad-core Tegra 4 SoC running the show. Like other all-in-ones Lenovo's released over the past year, this one's portable, with a battery rated for three hours. At 10 pounds, though, give or take, it's actually a good deal lighter than that other portable desktop Lenovo just announced. As for the ThinkVision model, it's crowned by a 28-inch, 3,840 x 2,160 display, allowing you to poke around Android 4.3 at a screen density of 157 pixels per inch. Note that the OS interface is actually upscaled from a 1080p resolution, but we were told that all 4K content is played in its native resolution. Additionally, the machine uses NFC and a "tap to connect" feature to pair devices, though you could also hook them up using one of the four USB ports, three HDMI sockets or the micro-USB connection.
