NVIDIA’s Kal-El Enables Realistic Physics and Dynamic Lighting For Mobile Devices

NVIDIA recently unveiled a new four core CPU for mobile devices at Mobile World Congress which promises to power 2560x1600, 300 DPI displays as well as enable realistic dynamic lighting and physics in mobile games, features that until recently were only possible in the realm of gaming laptops and desktops.

The quad core ARM CPU has been paired with a new 12 core GeForce graphics processing unit. The CPU alone is able to outperform the older Tegra 2 chip by close to 2x. With the additional GPU cores; however, NVIDIA has even more performance, and the ability to implement great looking games for mobile tablets and so called “super phones.”

At a resolution of 1280x800 (according to Engadget), the new Kal-El graphics demo shows off a new game featuring a glowing ball that acts as a truly dynamic light source in addition to realistic cloth physics. Using all four processing cores of the CPU allowed NVIDIA to implement cloth that reacts to the changing gravity of the game in a dynamic- and very realistic looking- manner. The mobile chip saw approximately 80% usage across all cores during the game demo. When NVIDIA disabled two of the CPU cores, the game became nearly unplayable, with the two remaining cores maxed out, the demo’s frame rate dropped to below 15 frames per second.

The new “Tegra Super Chip” will certainly allow mobile game developers to design immersive and realistic looking worlds as well as enhancing consumers’ ability to watch 1080p HD video with ease. The only drawback of the chip seems to be that battery technology is much slower to advance than transistor technology; therefore, it will be interesting to see how the new NVIDIA chip performs in that regard.

Recently, AMD launched two new AMD Embedded G-Series APUs (Accelerated Processing Units). The two new chips have a TDP rating of 5.5 and 6.4 watts, which represent a 39% improvement in power savings over the previous iterations. The 361mm² chip package is capable of being used in embedded systems without the need for a fan to cool it. The embedded chips include one or two low power x86 Bobcat processors and a discrete class DirectX 11 GPU on a single die.

AMD currently has three systems utilizing the new APUs, including a Pico-ITX form factor computer, a Qseven form factor computer, and a digital sign system. Buddy Broeker, the Director of Embedded Solutions for AMD stated that "today we take the ground-breaking AMD Fusion APU well below 7W TDP and shatter the accepted traditional threshold for across-the-board fanless enablement."

The two new chips are named the T40R and the T40E.  The chips both run at 1.00GHz; however, the 6.4 watt TDP T40E is a dual core chip and the 5.5 watt TDP T40R is a single core variant.  Both chips include an AMD Radeon 6250 GPU, a 64KB L1 cache, and a 512KB L2 cache per each CPU core.  Further, the chips feature an integrated DDR3 memory controller that can support up to 667MHz solder-down SODIMMs or two DIMM slots.  More details on the series as a whole can be found here.

Mobile and embedded processors continue to get smaller and faster. Have you seen any AMD powered embedded technology in your town?

Bottles are good, bottlenecks are bad. How well does your GPU and CPU match up?

If you have heard the term "bottleneck" when you have been describing your dream PC on the forums and wonder why people are referring to your CPU as the weak link when your GPU is so powerful that the CPU shouldn't have to do anything?  Unfortunately it is not that simple and a powerful GPU can be held back by a CPU that can't keep up with it.  Drop by Funky Kit for a look at bottlenecking by a serious overclocker who is quite used to overpowering CPUs.

"In the DIY computer world a lot of people are concerned about a video card (GPU) "bottlenecking" on a given CPU, or a given CPU bottlenecking a GPU. In this article I will explain what it is that they are talking about, as well as discussing whether or not it's worth being worried about. First off is the answer to the question "What is this bottlenecking you speak of?!"
