Tegra K1 chip to offer cutting-edge graphics for mobiles
January 15, 2014, 11:53 am

Major chip-maker Nvidia has announced a new processor destined for mobile devices that it says will offer better graphics than the Xbox 360 and PlayStation 3.

The Tegra K1 features 192 GPU (graphics processing unit) cores, based on the same Kepler technology used in high-end PC components. The advance is intended to help Nvidia compete against Qualcomm and Samsung for orders from manufacturers.
The company was beaten by rival AMD for the contract to make the graphics chips that power the recently released PlayStation 4 and Xbox One consoles.

Nvidia’s current generation Tegra 4 mobile chips - which feature 72 GPU cores - are used by Microsoft’s Surface 2 tablet, Asus’s Transformer Pad Infinity hybrid, the Toshiba Excite Pro tablet and Xiaomi’s Phone 3.

Nvidia’s chief executive Jen-Hsun Huang described the Tegra K1 as offering next-generation graphics to mobile devices for the first time when he announced the news at the Consumer Electronics Show.

Pointing out that while the new chip outperformed the last-generation consoles, Mr. Huang added that it required just five percent of their power. Two variants of the chip are to be released: one with a quad-core Cortex A15 CPU (central processing unit) designed by the British firm ARM; the second with Nvidia’s forthcoming dual-core Denver CPU, which is a customized version of ARM’s more powerful 64-bit V8 architecture. Offering a 64-bit CPU means the chip can theoretically be used in high-end mobile devices that require more RAM (random-access memory) than a 32-bit chip can address. Apple based the CPU of its recent A7 chip, which powers the iPhone 5S and iPad Air, on the same design.

However, Mr. Huang claimed the GPU cores in its chip meant the Tegra K1 would be three times more powerful than the A7. Nvidia hopes car makers will choose its chips to run their semi-autonomous driving technologies. Nvidia definitely has an uphill battle when it comes to convincing device makers to pick its solutions over Qualcomm or others, but Tegra K1 is likely the best story it has ever had in mobile.

If the company can get the chips out on time and they are competitive in terms of power efficiency, they should do better than any previous Nvidia solution. The real impact of Tegra K1’s GPU is that it raises the bar for what is expected in terms of graphics performance in mobile. And that’s a very good thing.” The 32-bit version of the Tegra K1 is intended to appear in devices before mid-2014, and the 64-bit version by the end of the year.
