NVIDIA Kal-El details reveal 5 cores, 1 for low power consumption

In today’s world we want fast-performing mobile devices which run for hours from a single charge, well it looks like NVIDIA could be onto a winner with its next-generation Kal-El processors. Apparently there will be one core which runs at a relatively low clock speed which has been optimized for efficiency – meaning it won’t drain your battery too quickly.

From what we can gather all Kal-El processors will feature four Cortex A9 high-performance cores which will obviously give compliant smartphones and tablets some serious processing power, however there will be an extra core dubbed the ‘Companion core’ which operates at a maximum clock speed of 500MHz and handles less intensive tasks – which to our knowledge means that when a device is set to standby or s barely being used the four high-performance cores will be in affect turned off. This ensure that battery life is preserved while the optimized Companion core carries out unchallenging processes.

The image below give us an idea as to how Kal-El chips should operate depending on what the tasks the device is carrying out – obviously the lower number of cores the less power is being used.

When you compare project Kal-El power consumption to Tegra 2 consumption it is obvious that Kal-El is the way forward – what is most alarming is the fact that project Kal-El apparently uses 61% less power than Tegra 2 chips when playing HD video, not only this but power consumption whilst gaming and playing MP3 files is significantly lower as well (see below).

With each core running at 1GHz we are told that benchmark scores are much higher than comparable Texas Instruments and Qualcomm mobile processors – not only this but power consumption is lower – what this means is basically the Kal-El chips will deliver a lot more in terms of performance than current offerings whilst not being too demanding on your device’s battery.

We can’t wait to find out more about the NVIDIA Kal-El project, when we do we will keep you posted. Some more details can be found over at Engadget.
