NVidia delays Tegra4 and revenues will be "flat"

NVidia the chipmaker famed for its high performance graphics cards and now low power Tegra smartphone chips has delayed the introduction of the Tegra4 for about 3 months so it can ensure the integrated LTE is fully ready (in the Tegra4i version). The Tegra3 is used is tablets like Google's Nexus 7.

LTE is seen as a must have for next generation tablets and integrated on to the CPU rather than a separate radio chip.

The delay will give Qualcomm who are already market leaders in the integrated CPU market with their Snapdragon series of cores - and they already have a 4 core chip on the market which will be used in high-end devices like Samsung's Galaxy S4 (in Europe at least).

Though NVidia has been reasonably successful with its Tegra3 chip, it's been a difficult journey with them having to make significant re-designs along the way to fix design issues with the chip. Getting the Tegra4i right will mean long term cost savings.

NVidia introduces Tegra3

NVidia has starting showing off it's new Tegra3 ARM based system (code named Kal-El). It has 4 cores based on the Cortex-A9 architecture and a 12 core GForce graphics GPU which allows for hardware accelerated affects such as dynamic lighting, Flash Player 11, HTML5 and WebGL.

It can also output to HDMI and support NVidia's 3D Vision technology which converts OpenGL to stereo 3D for viewing on a 3D TV.

However the main advancement is that it offers 3 times the graphics performance while offering a 61% lower power consumption than the Tegra2. It achieves some of this by actually having 5 CPU cores (the 5th being a low power ARM variant) and only using the Cortex-A9 cores for intensive CPU applications, so when a system is just playing music or some other non-CPU intensive task the big cores are powered down. This is known as variable symmetric multiprocessing (vSMP) and is a technology patented by NVidia.

The Tegra3 will be used in a forthcoming tablet from ASUS known as the Asus EE Pad Transformer Prime.

Other ARM licensees such as Texas Instruments (TI) are already snapping at NVidia's heals with forthcoming high performance OMAP chips which will support technologies such as holographic displays, HD augmented reality, real time voice translation and natural speech interaction.

There are now more ARM processors than actual arms in the world now.
