Nvidia Tegra K1: new details on energy efficiency consumption

When last March Nvidia started to talk and show the first details of its new Tegra K1 , professionals and above all the users in the process of changing tablet, laptop or smartphone, they began to desire this solution given the excellent performance that this chip should offer (especially in 3D).

What is interesting, however, is even more consumption and energy efficiency, an aspect on which Nvidia worked great.

Tegra K1 will use not only on mobile devices, but also on laptops, convertible, arriving at the server world, where, albeit with lower performance for example a Nvidia Tesla K40 itself, will be able to undoubtedly be more efficient.

Although the comparison may seem risky, the site wccftech.com publishes a slide that sees in front of the absolute performance of Tegra Tesla K40 with K1; the result in terms of raw power is not a surprise and of course in favor of Tesla K40, while when it comes to efficiency, we note that Tegra K1 is much better: 

WCCFTech.com	Tesla K40 + CPU	Nvidia Tegra K21
Single Precision Peak	4.2 TeraFlops	326 GFlops
Single Precision SGEMM	3.8 TeraFlops	290 GFlops
Memory	@ 288GB 12GB / s	2GB@14.9GB / s
Power (CPU + GPU)	~ 385Watt	<11Watts
Performance Per Watt	10SP GFlops Per Watt	26SP GFlops Per Watt

With these numbers Tegra K1 opens the road to become one of the most viable platforms for the coming years, especially given the versatility that should ensure consideration of the agreements with the automakers that take advantage of the Tegra solution for future infotainment systems.

NVIDIA Project Shield: 5-inch gaming console to Android

Apart from the world's quickest mobile processor Tegra 4 NVIDIA presented the public a new product in the field of gaming entertainment - mobile console called Project shield, which goes on sale in the second quarter.

Game console is based on the new NVIDIA chip with a clock speed of 1.9 GHz and running the operating system Android. The device has display with a diagonal of 5 inches, the resolution is 1280x720 pixels (294ppi). Of interfaces - HDMI connector to connect the device to an external monitor or TV, USB-port, audio jack and a memory card slot micro SD. The battery provides an autonomy of games from 5 to 10 hours and video playback in high resolution - up to 24 hours.

According to the manufacturer, the quality of built-in speakers Project Shield is on par with the top laptops, and from the communications capabilities is support for Wi-Fi and Miracast. Available standard analog sticks and all controls, familiar to players, including the side buttons.

As stated in NVIDIA, the console is created in order to "really enjoy" games for Android and Windows. If the first OS is more or less clear, from the Windows-based applications, things are slightly more complicated. It is assumed that the games for Windows, you can run only through the Big Picture Mode for Steam online streaming. Native games will be available from the online store TegraZone.

It is known that the system will be pre-installed mobile customers service Hulu, Netflix and Slacker Radio to view audio and video content over the Internet. Cost NVIDIA Project Shield has not been announced.

Nvidia has announced the world's fastest processor for smartphones and tablets

Nvidia announced a new generation of mobile processors - Tegra 4. The new chip is 6 times the speed of visual computing its predecessor, Tegra 3, and is "the fastest mobile processor "today.

Chipset Tegra 4, codenamed Wayne has 72 cores and Nvidia GeForce four basic and one additional cores. According to the manufacturer, the processor for smartphones and tablets faster than any current mobile chips on the market, and up to six times faster than Tegra 3 speed visual computing.

Processor, manufactured on 28-nm process technology, is based on the architecture of ARM Cortex-A15, which has also received a number of improvements, including nearly three-fold increased speed of surfing the Internet. Optional Nvidia chipset allows you to provide your mobile device supporting network LTE.

Another feature of the Tegra 4 has enhanced opportunities for photographers. The new processor is capable of doing HDR-pictures (images with high dynamic range), which will provide them with a better quality.

In addition, Nvidia claims that Tegra 4 consumes 45% less energy compared to previous generation chip, under standard operating scenarios. This is partly achieved through the Prism 3 technology, which reduces power consumption of the display illumination while maintaining high visual quality.

Saves battery power helps an additional fifth core - a decision the same processor Tegra 3, which also has five cores. At low load, such as when the user starts the application for social networks or mail checks, basic core idle, and tasks are passed on to the extra core with less power consumption.

According to the specs, Tegra 4 can provide up to 14 hours of video playback in high resolution on a smartphone.

Nvidia Tegra 4, leaked information, has 72 graphics cores

Leaked on the net the first image (and all information relating thereto) by Nvidia Tegra 4, the next product System-On-A-Chip Nvidia house. In other words is the processor that will be used on the next generation of smartphones and tablets Android (but not only).

It is a quad core processor (4 +1, as the previous Tegra 3), based on the Cortex A15 with ARM architecture. This is therefore a generation of completely different products, compared to the previous Tegra 3 quad core. This becomes even more obvious when we discover that the graphics processors increased from 12 to around 72.

The production process will then 28nm (the same of Snapdragon S4) and simplifying, we can say that this will ensure an energy saving definitely superior.

This support for resolutions up to 2660 x 1440 pixels, video playback 4K (the future, after the Full HD) and USB 3.0 ports. No mention of LTE connectivity, but will almost certainly be present and simply not mentioned in the leaked slide.

The challenge is now on: Samsung has unveiled its dual-core A15, the version quad-core is arriving ARM is already talked of an A50 (but not before 2014!). They begin the dance for Tegra 4: HTC is really the first to mount it?

Tegra 4 specification first exposure: the A15 architecture is 4 + core

The NVIDIA Tegra processor has just become very popular in the tablet machine and the smart phone , the VR-Zone today received some specifications about the next generation of the Tegra. The Tegra 4 codename Wayne (Batman Wayne) on the official road map is scheduled for 2012, but actually to 2013 will be launched, and most models have to wait until after a year and a half.

NVIDIA Tegra4

According to the latest intelligence, the Tegra will have four different models, but only three of which will be based on the latest ARM Cortex-A15 processor architecture, the other a will continue to follow the Tegra A9 architecture, while the core configuration or "4 - the PLUS-1 ", that is, the four main core plus a secondary core.

The first quarter of 2013, starting flagship model clocked at 1.8GHz, high-end positioning, for the 10-inch flat-panel machine equipment to the third quarter will be upgraded to 2.0GHz.

Is the same in the third quarter of next year, the two mainstream models will be available, one of the A15 architecture, clocked at 1.2-1.8GHz, still for the 10-inch flat-panel machine, market positioning will be more mainstream and even can bring cheap products The second is the A9 architecture, clocked at 1.2-2.0GHz, 7 inch tablet and smartphone-oriented, and in particular, by adding support on LTE100/HSPA42 network.

This will be the first Tegra to support LTE networks, can make up for the Tegra 3 is unable to support LTE, leading to a large number of 4G mobile phone to switch to the shortcomings of the Qualcomm platform.

As to the exact specifications of the GeForce GPU graphics core integrated in the Tegra 4, does not yet have a more accurate statement.

Obviously, until the second half of 2013 is the Tegra 4 real heat and light for the beginning of the year and a half before that will still see the Tegra 3, so come back to look at the Tegra 3 of the six models of frequency specifications, put into operation in progress.
