NVIDIA Tegra 4 chipset: faster performance, longer battery life

NVIDIA has announced the Tegra 4 chipset, which combines an NVIDIA GPU with a quad-core ARM Cortex-A15 CPU.

According to ARM, the Cortex-A15 delivers around twice the performance of the Cortex-A9, used in Tegra 3, and is able to address up to 1TB of RAM.

The Tegra 4 GPU has 72 cores, compared to 12 cores on Tegra 3.

In addition, NVIDIA is including what it calls “Computational Photography Architecture” which uses both CPU and GPU to improve photographic capability.

The part of the announcement that most caught my eye though is the claim of “up to 45 percent less power than its predecessor, Tegra 3, in common use cases”.

Tegra 4 will enable high-performance smartphones, but I am more interested in what this and other next-generation chipsets will offer for tablets. Microsoft’s Surface RT would be more compelling with Tegra 4, rather than its current Tegra 3, since it suffers from poor performance in some cases (Excel, for example) and longer battery life would do no harm either.

There will be even less reason to want a laptop.

NVIDIA’s newly announced Project SHIELD gaming portable also uses a Tegra 4 chipset.

3D games: gimmick or the next generation?

I’m attending NVIDIA’s GPU technology conference, and at the exhibition here I took the opportunity to view some 3D images on some Lenovo (and of course NVIDIA) kit.

I was impressed; yes you have to wear the special specs, but the results are superb. The images are more immersive and more realistic, and I can see the appeal.

I am still not sure though whether 3D games will take off. The screens are substantially more expensive, the specs are inconvenient, and there are not many games.

We have also seen how Nintendo’s 3D support in the DS was insufficient to generate much momentum.

The question then is whether 3D gaming will ever be mainstream. Looking at a high quality 3D display makes you think that it must catch on eventually; but it has a lot stacked against it.
