Nvidia announces own 'Shield' gaming device at CES


Recommended Posts

This just out -- nVidia's Tegra 4 pegged below the quad-core PowerVR GPU in the Apple A6X and the Mali-T604 in the dual-core Samsung Exynos 5250.


nVidia revealed what we were all expecting at CES 2013 - A quad-core Tegra 4 SoC based on the Cortex-A15 architecture. During the presentation, Jen-Hsun Huang showed off browsing benchmarks where the Tegra 4 came out on top and above both the iPad 4 and Nexus 10.


According to early benchmark results, however, Nvidia's latest Tegra SoC underperforms in the popular graphics benchmark GLBenchmark 2.5 and even comes out behind the Apple and Google tablets. A reasonable explanation for the lower than expected numbers are the immature drivers for as the Tegra 4 SoC is not yet available in the consumer market.




So back to the drawing board it is for better code.

The chip, which retains the same 4-plus-1 arrangement of its predecessor, arrives with a whopping 72 GeForce GPU cores -- effectively offering six times the Tegra 3's visual output and is based on the 28nm process. It also is the first quad-core processor with Cortex A15 cores on-board, and offers compatibility with LTE networks through an optional chip. NVIDIA claims this piece of silicon is the world's fastest mobile processor


The Tegra 4 also introduces new computational photography architecture, which adds a new engine to drive the image processing and significantly improve the amount of time it takes to calculate the necessary mathematics 10 times faster than current platforms. To show off its power, NVIDIA demonstrated HDR rendering on live video. The chip is also capable of implementing HDR in burst shots and with LED flash. The idea, NVIDIA says, is to eventually make our mobile cameras more powerful than DSLRs, and this is certainly a step in the right direction.


The Tegra 4 will also enable 4K ultra high-definition video support, as well as PRISM 2 display tech that claims to reduce the power used by the backlight. Doing so will result in a 45 percent decrease in power consumption when compared to Tegra 3.


what do you want more?

Usual blabber of Nvidia claims this and Nvidia claims that and when the chip actually comes out, we all know half of it is just marketing fluff playing out with words (like how they conveniently say it's a SEVENTY TWO core GPU, as if it means it is 18 times more powerful than iPad's quad core GPU)..

Anyways, they just showed one benchmark for their CPU where T4 was supposedly ~50% faster than Nexus 10 in loading up web pages (No clocks, no memory configurations, no governor configurations mentioned, all of which are much more conservative in a retail device than in an internal test platform device). They also didn't say was that it was a browser v/s chrome test. Now, in the new chrome beta that google launched couple of days ago, Javascript alone is around 25-30% faster. So, where does that leave the comparison? You do the math.
