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.

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.

2013 Elite Mobility APU - Temash
AMD has a lot to say today. At an event up in Toronto this month we got to sit down with AMD’s marketing leadership and key engineers to learn about the company’s plans for 2013 mobility processors. This includes a refreshed high performance APU known as Richland that will replace Trinity as well as two brand new APUs based on Jaguar CPU cores and the GCN architecture for low power platforms.
Josh has put together an article that details the Jaguar + GCN design of Temash and Kabini and I have also posted some initial performance results of the Kabini reference system AMD handed me in May. This article will detail the plans that AMD has for each of these three mobile segments, starting with the newest entry, AMD’s Elite Mobility APU platform – Temash.
The goal of the APU, the combination of traditional x86 processing cores and a discrete style graphics system, was to offer unparalleled performance in smaller and more efficient form factors. AMD believes that their leadership in the graphics front will offer them a good sized advantage in areas including performance tablets, hybrids and small screen clamshells that may or not be touch enabled. They are acknowledging though that getting into the smallest tablets (like the Nexus 7) is not on the table quite yet and that content creation desktop replacements are probably outside the scope of Richland.
2013 Elite Mobility APU – Temash
AMD will have the first x86 quad-core SoC design with Temash and AMD thinks it will make a big splash in a relatively new market known as the “high performance” tablet.
Temash, built around Jaguar CPU cores and the graphics technology of GCN, will be able to offer fully accelerated video playback with transcode support as well with features like image stabilization and Perfect Picture enabled. Temash will also be the only SoC to offer support for DX11 graphics and even though some games might not have the ability to show off added effects there are quite a few performance advantages of DX11 over DX10/9. With more than 100% claimed GPU performance upgrade you’ll be able to drive displays at 2560x1600 for productivity use and even be able to take advantage of wireless display options.
The Architectural Deep Dive
AMD officially unveiled their brand new Bobcat architecture to the world at CES 2011. This was a very important release for AMD in the low power market. Even though Netbooks were a dying breed at that time, AMD experienced a good uptick in sales due to the good combination of price, performance, and power consumption for the new Brazos platform. AMD was of the opinion that a single CPU design would not be able to span the power consumption spectrum of CPUs at the time, and so Bobcat was designed to fill that space which existed from 1 watt to 25 watts. Bobcat never was able to get down to that 1 watt point, but the Z-60 was a 4.5 watt part with two cores and the full 80 Radeon cores.
The Bobcat architecture was produced on TSMC’s 40 nm process. AMD eschewed the upcoming 32 nm HKMG/SOI process that was being utilized for the upcoming Llano and Bulldozer parts. In hindsight, this was a good idea. Yields took a while to improve on GLOBALFOUNDRIES new process, while the existing 40 nm product from TSMC was running at full speed. AMD was able to provide the market in fairly short order with good quantities of Bobcat based APUs. The product more than paid for itself, and while not exactly a runaway success that garnered many points of marketshare from Intel, it helped to provide AMD with some stability in the market. Furthermore, it provided a very good foundation for AMD when it comes to low power parts that are feature rich and offer competitive performance.
The original Brazos update did not happen, instead AMD introduced Brazos 2.0 which was a more process improvement oriented product which featured slightly higher speeds but remained in the same TDP range. The uptake of this product was limited, and obviously it was a minor refresh to buoy purchases of the aging product. Competition was coming from low power Ivy Bridge based chips, as well as AMD’s new Trinity products which could reach TDPs of 17 watts. Brazos and Brazos 2.0 did find a home in low powered, but full sized notebooks that were very inexpensive. Even heavily leaning Intel based manufacturers like Toshiba released Brazos based products in the sub-$500 market. The combination of good CPU performance and above average GPU performance made this a strong product in this particular market. It was so power efficient, small batteries were typically needed, thereby further lowering the cost.
All things must pass, and Brazos is no exception. Intel has a slew of 22 nm parts that are encroaching on the sub-15 watt territory, ARM partners have quite a few products that are getting pretty decent in terms of overall performance, and the graphics on all of these parts are seeing some significant upgrades. The 40 nm based Bobcat products are no longer competitive with what the market has to offer. So at this time we are finally seeing the first Jaguar based products. Jaguar is not a revolutionary product, but it improves on nearly every aspect of performance and power usage as compared to Bobcat.

Envision Peripherals Inc. (EPI), a company that sells Philips monitors in North America recently announced three new high resolution IPS desktop monitors. The company is releasing one 29” 21:9 monitor for consumers and two high resolution displays for professionals.
Philips Brilliance 29” UltraWide Monitor
This Philips monitor is of the 21:9 variety and offers up a resolution of 2560 x 1080 on its AH IPS display. The monitor features a narrow bezel, built-in speakers, and comes bundled with SmartControl software to adjest settings via a PC software application.
It has DL-DVI, DisplayPort, HDMI, and (optional) Thunderbolt video inputs. It supports MultiView technology, which allows the monitor to accept multiple video inputs and display them simultaneously on the screen.
The Philips Brilliance 29” UltraWide display is available now at online retailers like Amazon. While it has an MSRP of $599 according to the press release, Amazon is actually charging $667.90 for the monitor currently.
While the Brilliance 29” UltraWide is aimed at consumers, the following two monitors are intended for professionals doing CAD, finance, and art/design work.
P-Line 29” UltraWide Monitor
The P-Line 29” UltraWide is a 21:9 monitor for professionals. It features a 2560 x 1080 resolution AH IPS display with MultiView technology and a “ultra narrow” bezel. EPI claims that the display has both a 178-degree vertical and horizontal viewing angles. There are four USB 3.0 port as well as a height-adjustable stand.
Video inputs include DisplayPort 1.2a ports that allow daisy chaining monitors. The MultiView technology also allows the display to show two display inputs simultaneously.
The monitor is available now to business customers from resellers like CDW for $699.
P-Line 27” Quad HD Monitor
Finally, the P-line 27” Quad HD monitor is the final new professional series display. It has the highest resolution at 2560 x 1440 (109 PPI). This IPS display supports 8-bit color and has a professional price to match. The monitor itself has a height-adjustable stand, built-in speakers, a 2MP webcam with microphone, USB 3.0 ports, and a PowerSensor which detects when the user leaves the computer and automatically dims the display. EPI claims that the PowerSensor results in up to 80% power savings. It would be useful for businesses, though less crucial for home users.
Like the P-line 29” UltraWide, this monitor can daisy chain other monitors to the PC video output via DisplayPort connectors. Video inputs include DL-DVI, DisplayPort, HDMI, and Thunderbolt.
It is available now from resellers with an MSRP of $799.
