Batteries to last 40% longer with Tegra 3 and DIDIM technology
The Tegra 3 processor is almost upon us in Asus and HTC tablet guises and will hit the smartphone market soon afterwards however there have been concerns that the quad-core chip would gobble power faster than previous generation chips, rendering it useless.
Well it appears that you will actually be treated to longer battery life not a shorter one.
The display is likely to be the main cause of power consumptions, not cpu usage, however with these new Tegra 3 quad cores you’re actually likely to use less power for display, but with the same visible output.
During the UBS Global Technology and Services Conference, NVIDIA CEO Jen-Hsun Huang broke down in detail a new technology in Tegra 3. The tech is said to reduce backlight power by 40%, which in turn, translates into longer battery life. Expect Android tablets with 14 hours of video playback.
This technology is known as DIDIM and Jen-Hsun describes it as:
“It’s the ability to per pixel, per frame, per scene to modulate the backlight so quickly that we over a long period of time, reduce the amount of backlight intensity and backlight energy by nearly half. We save as much power in the backlight without changing the visual fidelity at all to save, essentially, the entire power used by our chip.”
When the Tegra 3 processor is in full active mode, it consumes 1-2 watts, compared to the 3-6 watts of a non-Tegra 3 device depending on brightness.
With such a groundbreaking development Nvidia are surely going to be leading the pack, expect to see their chips on your tablet and smartphone in the near future.
