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.

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.

NVIDIA blew reviewers away with its flagship GTX 680, but building cards for the low-end is a whole different challenge. The GT 640 hits the $99 price point, where it sits right between the AMD Radeon HD 7750 at $109 and the last-gen Radeon 6670 at around $80. As it turns out, these rivals pull off something of a pincer movement, leaving NVIDIA's card little room to retaliate. The GT 640 contains a 28nm Kepler chip, but it's a cutdown version of the silicon with just 384 CUDA cores, a poor memory bandwidth of 28.5GB/s and no GPU Boost feature -- which means the card can't boost its 900MHz to make use of thermal headroom. These limitations have a significant impact on the benchmarks, as you'll see in our little review roundup after the break.

Not quite fully sated with the latest Apple updates from this year's WWDC? Without doubt, one of the most anticipated goodies to come from the keynote yesterday was the introduction of the MacBook Pro into the Retina Display-fold. We'll, of course, be giving all the new hardware our own thorough shakedown, but in the meantime, AnandTech has given that new display a detailed dissection. In summary: excellent brightness and solid black-levels fend off the glare, apps look amazing, upscaling will cover you in the meantime. For the full nitty-gritty though, number by number, be sure to hit up the source.
