NVIDIA's Tegra 4i System on a Chip includes a software defined radio that works as a LTE modem. This i500 LTE modem uses general purpose deep execution processors (DXP) and is as much as 40% smaller than a hardware LTE modem according to the company.
At Mobile World Congress earlier this year, the modem was able to reach 100Mbps throughput. After a recent software update, the Tegra 4i SoC in NVIDIA's Pheonix reference platform achieved 150Mbps throughput in a demo at CITA 2013 in Los Angeles this week.
The reference phone was connected to a test network during the demo rather than a live cellular network. The cellular network test equiptment showed the Pheonix platform was connected at the full 150Mbps link speed. In addition to this, NVIDIA showed the Tegra 4i-powered Pheonix phone connected to a live AT&T LTE network streaming video and making voice calls.
The interesting bit about the i500 modem in the Tegra 4i is its software defined nature. NVIDIA was able to upgrade the modem's capabilites through software rather than needing to redesign the hardware. This would be a big plus to consumers as they would be able to take advantage of the faster network speeds as they become available without needing to replace their phones. NVIDIA did note that in addition to the LTE Cat 4 support, the i500 is also backwards compatible with LTE Cat 3, 3G, and 2G networks. I'm interested to see what the power consumption of thei500 is like compared to LTE modems implemented in specialized hardware. The i500 is smaller and more flexible, but SDR can use more power due to its general purpose hardware units.

With 768 more CUDA Cores than the 680 but 384 less than the TITAN the 780 offers improvements over the previous generation and will be available for about $350 less than the TITAN. As you can see in [H]ard|OCP's testing it does outperform the 680 and 7970 but not by a huge margin which hurts the price to performance ratio and makes it more attractive for 680 owners to pick up a second card for SLI. AMD owners with previous generation cards and deep pockets might be tempted to pick up a pair of these cards as they show very good frame rating results in Ryan's review.
"NVIDIA's new GeForce GTX 780 video card has finally been unveiled. We review the GTX 780 with real world gaming with the most intense 3D games, including Metro: Last Light. If the GTX TITAN had you excited but was a bit out of your price range, the GTX 780 should hold your excitement while being a lot less expensive."

Hitachi Global Storage Technologies (HGST, which is now owned by Western Digital) has developed a new 2.5” mobile hard drive called the Travelstar 5K1500. The hard drive uses three 500GB platter drives for a total capacity of 1.5TB. HGST claims that the drive is the highest capacity 9.5mm mobile drive on the market. Additionally, the company has stated that the new drive is faster than its existing two-platter hard drives according to the PCMark Vantage and PCMark 7 benchmark suites.
The 1.5TB Travelstar 5K1500 is a 5400 RPM hard drive with 32MB of on-board cache, a 6Gbps SATA III interface, and shock protection features.
The new mobile drive will be used in external hard drives, all-in-one systems, and notebooks where storage space is valued more than pure performance. It will be available sometime in June for an as-yet-unannounced price point. Another version of the Travelstar 5K1500 that offers automatic encryption of data will be available in Q3 2013.

Be quiet!, a power supply manufacturer based in Germany, has announced that almost all of its recent power supply lineups are fully compatible with Intel's upcoming Haswell processors. The PC Perspective team has talked in-depth about the new C6 and C7 sleep states used by Haswell CPUs. However, for the uninitiated, the new Intel processors have two new low power sleep states. The lowest state, C7, draws as little as 0.05A from the 12V PSU rail. That is a good thing, but not all power supplies will be compatible with the new sleep states as such low load on the 12V rail was not a concern when the PSUs were designed and manufactured. Notably, even incompatible power supplies will still work in Haswell systems, but those computers will not be able to enter the lower-power C6 and/or C7 sleep states.
There is good news for users of Be Quiet! Power supplies, however. The following power supplies are fully compatible with Haswell and the new sleep states:
- Dark Power Pro 10 Series (all models)
- Straight Power E9 Series (all models)
- Pure Power L8 Series (all models)
- System Power 7 Series (all models)
- Pure Power L7 Series (the 630W and 730W models only)
Older Be Quiet! power supplies will still work in Haswell systems, but use of the lowest power C7 state is not recommended. Fortunately, most desktop users can live without the new low power states (which, while nice to have, the new sleep states are more beneficial to laptop users).
As the launch of Haswell approaches, more and more PSU manufacturers are releasing compatibility information. So far, the following companies have put together compatibility lists.

In addition to Be Quiet!, Thermaltake has announced its own list of Haswell-compatible PSUs. The majority of high end Thermaltake power supplies will work with Haswell and its new sleep states. Further, all of the current generation high-end and mid-range Thermaltake power supplies are compatible with the new CPUs.
Power supplies in the Toughpower, EVO, and Smart M family are compatible with Haswell. Specifically, the chart below details which specifc models are compatible with Haswell and the new C6 and C7 low power sleep states.
The following companies have also listed Haswell-compatible power supplies:

A security expert recently reminded people that the Preferred Networks List Bug which was identified in 2004 has only ever been addressed by Microsoft. All other mobile OSes, from Apple to BlackBerry can accidentally expose their PNL to an eavesdropper who can then spoof it. If you like setting up autoconnect on your devices you might want to double check the name of your active connections occasionally; if you are connected to your home WiFi while you are out you might have a problem. Catch more at The Register.
"Security expert Raul Siles has warned that years after it was first identified, the Preferred Networks List (PNL) Wi-Fi bug remains unaddressed on many an iPhone, Android phone, and Windows or BlackBerry handset."
