Tom's Guide: what should we expect from 4G?

Our colleagues and neighbors at Tom's Hardware just upload a file on the 4G, fourth generation mobile network. Successor to 3G (UMTS) and its evolution (3G and 3G + HSDPA + HSUPA), 4G can be divided into two standards: 3.9 G (LTE) and 4G (LTE Advanced). In both cases, 4G promises speeds much higher than that of the 3G mobile internet connection ...

Ti a GTX 550 to 1015 MHz Asus

Galaxy and Zotac are not the only ones to offer overclocked GeForce GTX 550 Ti plant. Asus has indeed announced a similar model, the UL (Timati) ENGTX550 DC/DI/1GD5 Ti. The manufacturer goes further than its competitors because it pushes the GPU GTX 550 to 1015 MHz Ti, against "only" for the 1000 MHz maps of the Galaxy and Zotac.

Remember that the GPU clock reference designs is only 900 MHz. The 192 CUDA cores for their turn to 2030 MHz, while the GB of GDDR5 memory running at 1050 MHz on a 192-bit bus. This overclocked GeForce GTX 550 Ti also benefits from a cooling system DirectCU advertised as more effective than the reference.

Intel wants a piece of cake Android, Chrome OS

Intel does not want to leave only the ARM processors on the market for devices running Android and Chrome OS.

ARM - who does what Apple A5 (12)

Lets see the section "ARM: who does what" with Apple A5. This new SoC succeeds A4 used in the iPad, the iPhone and iPod Touch 4 4G. The A5 is a new generation of SoC, which lies between OMAP4 and OMAP5 or between 2 and Tegra Tegra 3. It's a smart intermediary because the CPU is a classical model, already used but the graphics chip is much faster than the competition.

Only small fault current, the chip is etched into 45 nm and is therefore much bigger than the Apple A4. For the processor is the classic type of two cores Cortex A9, with SIMD (NEON) and FPU and 512 KB of cache per core. It is a core about 25% faster than the Cortex A8 A4 in normal and really a lot faster on floating point computations.
