Android 4.3 supports TRIM, improves performance on Nexus devices

It’s no secret that many Android phones and tablets show a decrease in performance over time. Nexus devices are not immune — it’s particularly noticeable with the original Nexus 7. Our friend Brian Klug over at AnandTech discovered an interesting tidbit while testing the new and improved Nexus 7: Android 4.3 supports TRIM. What this means is that Google’s mobile OS can now instruct the flash storage controller when to collect / recycle unused data pages / blocks. The net result is that devices running Android 4.3 will no longer become sluggish with time — in fact, existing Nexus handsets and tablets will see performance improve after the update. It also looks like Jelly Bean invokes TRIM maintenance once within a 24-hour window (after one hour of inactivity), and only if the battery is 80% full (30% when charging). Follow the source link below for all the details.

Nintendo’s Wii U gets gutted in the name of specs

Nintendos Wii U gets gutted in the name of specs

Curious about what silicon is powering Nintendo’s Wii U? So was Anand Lal Shimpi, who tore his brand new console to pieces in the name of science. At its heart is a multi-chip module with a PowerPC-based CPU, built on IBM’s 45-nanometer process, paired with a GPU similar to AMD’s RV7xx design. These two components share 2GB of DDR3 RAM (plus an unspecified amount of eDRAM), while Anand calculates memory bandwidth to be 12.8GB/s. That’s around the same as as the Nexus 10 and new iPad, but should throw more frames at your eyeballs because those other devices are operating at much higher resolutions. In terms of power consumption, the Wii U’s innards draw a pretty constant wattage regardless of load, drawing 32.8W when rendering the disc menu and 33.0W when playing Super Mario U — for comparison, that’s around a third of the appetite of the greedy little PlayStation 3 Slim.
