An overview of Thunderbolt Technology
The promise of Thunderbolt connectivity has been around for a couple of years now. Today, Thunderbolt is finally finding its way to the PC platform in the form of motherboards from ASUS and MSI. First unveiled as "Light Peak" at the Intel Developer Forum in 2009, the technology started out as a way to connect multiple devices to a system over a fiber optic cable (hence the 'light' in the name), though the final products have changed the implementation slightly.
The first prototype implementations actually used a USB-style connection and interface. It further required fiber optic cables. When it was renamed to Thunderbolt and then released in conjunction with a new lineup of Apple MacBook laptops, not only did the physical interface move to a mini-DisplayPort connection but the cable was made to use copper rather than fiber. Without diving too far into the reasons and benefits of either direction, the fact is that the copper cables allow for modest power transfer and are much cheaper than fiber optic variants would be.
Thunderbolt's base technology remains the same, however. It is a transfer standard that allows for 10 Gbps of bandwidth for each channel (bi-directional) and concurrently supports both data and display connections. The actual interface for the data path is based on PCI Express and connected devices actually appear to Windows as if they are internally connected to the system which can offer some interesting benefits – and headaches – for hardware developers. The display connection uses the DisplayPort standard and can be used along with the data connection without affecting bandwidth levels or performance.
For current Intel processor implementations, the Thunderbolt connection is supported by a separate controller chip on the motherboard (or a riser card) – and some routing is required for correct usage. The Thunderbolt controller does not actually include a graphics controller, so it must be fed an output from another graphics processor, obviously in this case directly from the Ivy Bridge / Sandy Bridge processors. In theory, these could be from other controllers, but with the ubiquitous nature of integrated processor graphics on IVB and SNB processors, this is going to be the implementation going forward according to motherboard and system designers.

Every June, the tech world lights up with numerous tech conferences that pack dense information into a couple days (and takes weeks to fully decompress). One of the bigger conferences (by a single company, Computex is its own beast) is Google I/O.
The biggest rumor to come out concerning this year’s Google I/O announcements is an ASUS manufactured 7-inch Nexus Tablet. It is allegedly packing some high end hardware with the Tegra 3 Soc, up to 16GB of memory, IPS display, and an extremely attractive price at less than $200. Beyond that, we can expect Jelly Bean (Android 4.1) information, developer talks, software demos, and more talk of Google Wallet, and NFC technology. Heck, Google may even make a second attempt at pushing Android@Home (or maybe not heh).
Being June 27th, it is the first day of Google I/O and that means it is time for keynotes! On the schedule for today, Google has talks on the new aspects of Android, Google Play, cloud computing, Youtube cloud rendering, Google+ (including Hangouts), and new features of Google Maps. They also have talks scheduled with Google Drive information that should demo some of the things developers can do with the Drive SDK.
We are excited to see if the Nexus tablet rumors are true or not, as well as learning more about the latest version of Android. If you are interested in watching the event, check out the Google I/O schedule where you can tune into the most of the events live. The first event starts soon at 9:30am PST!
Check back later today for updates!
Update: (9:00 PST) A leaked screenshot indicates that the Nexus tablet may be called the Nexus 7.
Update: (9:30 PST) Vic Gondotra stepped on stage to kick off the Google I/O conference. He stated that there are more than 30,000 people in attendance.
What are you excited about at Google I/O? Let us know in the comments below!

For months, rumors have been flying about Google introducing a "Nexus" tablet platform, reminiscent of what they have done with previous phone releases. With the Google I/O Day 1 Keynote just hours away, we at PC Perspective are throwing our hat into the ring in predicting what Google is likely to announce.
During meetings with ASUS at CES 2012, representatives from the company introduced us to a series of 3 tablets, including the Eee Pad MeMO 171, and the later to be named Transformer Prime Infinity. While these two tablets have been released or are soon to be released in some retail capacity, there is one product that they were talking about that morning which ASUS has gone completely silent on.
While ASUS was being a little cagey about the product at the time, we did recieve some initial information for this Eee Pad MeMO 370T. We were told that it was a Tegra 3 product, and that it would come in at around $250. This device however was not particularly accessible to us like the rest of the time as it was locked in a protective case. We could use the screen of the device, but that was about it. In fact, the pictures that we snapped of this device were frankly just by chance, as we were expecting to see this product later down the line and didn't put much focus onto it.
Moving on to later in the same day, we attended the NVIDIA press conference, which was very Tegra focused. One of the big announcements was an unnamed ASUS $249 Tegra 3 Tablet. NVIDIA was also being pretty silent about this product, but we once again expected news about their low-cost platform for tablet (Kai) in the coming weeks.
NVIDIA announces $249 ASUS Tegra 3 Tablet at CES
However we never recieved any more information in the following 6 months from either ASUS or NVIDIA, which brings us to this year's Google I/O. With Google expected to be working with ASUS on a 7" tablet, and the fact that NVIDIA was so hyped about a product that was never heard from again, it becomes a safe assumption to look towards the long forgotten Eee Pad MeMO 370T as the likely platform. While the styling may be altered, any potential Google/ASUS 7" tegra tablet will certainly have had roots in the Eee family.

ASUS recently posted a few teaser photos of its upcoming Republic of Gamers branded 7970 graphics card. The Matrix HD 7970 is a three slot design with the company’s DirectCU II heatsink, dual fans, DIGI+ VRM, and (of course) AMD’s 7970 Tahiti GPU core. While likely not based on the higher-binned cores used in the new 7970 GHz Edition graphics cards, with the large cooler and extra power phases that ASUS is packing into this Matrix GPU it should overclock to similar levels of performance.
The card features fans, and a large dual slot cooler with the traditional red and black ROG theme. The ASUS and Matrix logos are etched into the side of the card as well. The PCB is black and further covered by a bracing plate to reinforce the PCB to support the weight of the cooler. On the front of the card, it houses an air vent, two DVI connectors, and four DisplayPort video outputs. On the back of the card are four buttons. Two of the buttons with plus and minus symbols let you adjust the core voltage in preset jumps. The Safe Mode button next to the minus button clears the overclocks from the BIOS and resets the card to default settings. Finally, the red button will spin the fan up to 100% to overclock the card as far as possible. They also have a bank of LEDs below the buttons that offer at-a-glance load monitoring (really only useful for those testing outside a case...). In the rear corner of the card is two eight pin PCI-E power connectors. Then, on the underside (top when installed in the case) of the graphics card’s PCB, ASUS has a VGA Hotwire port which allows the card to interface with the ASUS OC Key and Extreme edition motherboards (such as the Maximus V and Rampage IV Extreme). There are also voltage checking points.
Internals are somewhat similar to ASUS Radeon HD 7970 DirectCU II, but with some aspects ratcheted up. The power phases, for example, have increased from 12 phases to 20 on the Matrix card. It continues to use the 7970 “Tahiti” GPU with 2048 shaders, 32 ROPs, and AMD’s Graphics Core Next architecture. ASUS is packing 3GB of GDDR5 memory with a 384-bit memory interface. ASUS has stated that both the GPU core and memory will be overclocked from the factory. Unfortunately, they have not released any specific numbers. We will have to wait until the card is closer to the launch date for that information.
The ASUS ROG Matrix graphics card will be launching in Q3 of 2012. It will be aimed at extreme overclockers – especially those that are already using Republic of Gamers branded motherboards from ASUS. What do you think of this new card, especially now that AMD has launched its 7970 GHz Edition reference GPU? You can find more photos of the card over at the ASUS website.

ASUS has been paying attention to the complaints many people have about the resolution of ultrabooks and with the UX31 have provided an 11.6" 1600 x 900 LCD. The aluminium clad Ultrabook uses the Core i5-2557M and HD3000 graphics, 4GB DDR3 and a 256GB SSD in its thin and lightweight frame. Unfortunately Hardware Canucks ended up less than impressed with the chicklet style keyboard nor the track pad and they found issues with the WiFi as well. On the positive side the battery life was impressive as was the audio so do not dismiss this Ultrabook because of a few small issues.
"Mobile computing is quickly evolving with thinner, more versatile designs and no product better defines this focus than ASUS' new Zenbook series of Ultrabooks. The UX31 has been around for a while but it still represents the pinnacle of industrial design with a sleek body and even better looking specifications. But in an environment that's cluttered with lower priced competitors, this Ultrabook will be fighting an uphill battle for recognition. "

The Tech Report found a few more Computex 2012 pictures to show off, including a teaser from NZXT of the previous Phantom model as the new model is still under NDA, no such problem for the case modders showing off at the Thermaltake booth nor for InWin and their new H-Frame case. Sticking with the cooling motif is this new fan from Spire which uses a new type of bearing to provide a longer life and Corsair's two new lineups of 120mm and 140mm fans, the AF series designed to maximize air flow through a case and the SF series for heatsinks and radiators which benefit more from the increased static pressure larger fan blades can provide. From Rosewill they spotted a silent PSU, SilverStone a SFX model perfect for an HTPC and big 1200W digitally controlled PSU from Corsair. Wrap up the tour with some bad news about the expected delay of Trinity on the desktop and some good news for audiophiles from ASUS' Xonar team.
"We've wrapped up our Computex coverage with another round of news. On tap: the PSUs and case mods that stood out at the show, new fans from Corsair and Spire, a chat with Asus' Xonar audio team, details on NZXT's next-generation Phantom enclosure, and word of a delay to AMD's desktop Trinity APU."

Tagged: wireless, gaming laptop, gaming, computex, ASUS ROG, asus, 802.11ac, 5GHz wifi
Earlier today we posted a couple of teaser photos showing off some of ASUS’ upcoming products. One of the devices was a gaming laptop called the ASUS G75. Engadget has managed to get their hands on some more information regarding a variant of the G75 – the G75VW. According to the site, the gaming laptop is rocking an Intel Ivy Bridge processor, GeForce GTX 670M, and DDR3 memory (known because of the CPU used). That hardware is then powering a 1080p display, which the GTX 670M should have no problem driving but is a bit depressing to see on a high end laptop of this size (approximately 17”). The real kicker though is in the wireless card that it is allegedly packing: an 802.11ac card.
The ASUS G75 gaming laptop
Engadget states that although the information sheet next to the laptop at ASUS’ Computex booth did not list any 802.11ac compatibility, wireless chip maker Broadcom (manufacturer of chips that are used in many wireless routers and NICs) has stated that it does in fact have an 802.11ac NIC in it. Senior Vice President Michael Hurlston told members of the press at Computex 2012 that the ASUS G75VW is the “World’s first 5G Wi-Fi laptop.” He further stated that the computer would be arriving in the hands of consumers “very shortly.”
Interesting stuff, and although the “5G Wi-Fi” – so called because it is the fifth generation of consumer grade Wi-Fi (though not the 5th gen if you count all iterations of the wireless 802.11 standards) – is not yet official and set in stone, it is very close and I would not be surprised to see the technology in a laptop like this particular ASUS at this point in the game.
And to think that I just got done upgrading my network to Gigabit Ethernet and 802.11n about two months ago! Even so, I’m excited for the upcoming standard because I want to test its usefulness in getting live TV from my CableCARD tuner to the living room and Katy’s wireless laptop without stuttering – something even wireless N with MIMO can’t do with devices in the same room. So far, the only thing stable enough has been wired Cat5e Ethernet (both 100Mbps and 1000Mbps hardware seem to work without issues). And because it’s proving difficult to get a wired connection from the router to the TV (Xbox 360 used as Windows Media Extender), I’m ready to try out some 802.11ac stuff to see if it can really deliver on the increased bandwidth!

ASUS has a history of showing off crazy high-end concept motherboards that are not likely to come to market but may help influence future motherboard products by getting the creative sparks of innovation flowing in engineers’ minds.
At this year’s Computex 2012, Asus showed off two concept motherboards that it is calling Zeus and Wolverine. While Zeus tackles Thunderbolt and integrated GPUs, Wolverine approaches the problem of getting clean power to the CPU by pushing the limits of the number of power phases that can be integrated into ATX-sized motherboards.
You will notice on the Zeus motherboard that the bottom of the board holds a bank of two 8 pin and two six pin power connectors. The two eight pin connectors are labeled VGA 1 and VGA 2 while the two six pin connectors are labeled VGA 3 and VGA 4 respectively. At first this seems like a regular X79 chipset (socket 2011) based motherboard with giant heatsinks for overclockers. After doing a double take (at least I did), you will notice that the board has no PCI-E connectors!
Instead, the board has a large heatsink, and under that heatsink are two GPUs in CrossFire configuration. Tech Power Up believes that the GPUs being used are two AMD 7800 “Pitcairn” series mobile graphics cards in CrossFire configuration. While the desktop variants are fairly low power, they would need active cooling or a larger heatsink, which I think is what lead them to consider that ASUS may be using mobile-class cards. Reportedly, ASUS did not create this board to suggest GPU integration, but to show off dual Thunderbolt ports on an X79 motherboard.
Connectivity on the board includes a socket 2011 CPU, eight DDR3 DIMM slots, ten SATA connectors, (and on the rear IO panel) a WiFi radio, eight USB 3.0 ports, two Thunderbolt ports, Gigabit LAN, 7.1 channel analog audio output, optical audio output, HDMI output, DisplayPort output, and two eSATA ports.
As far as the dual GPU integration goes, however... I don’t expect we’ll be seeing a move in the industry like this any time soon, at least not on high-end Enthusiast boards (though I could see an argument for small form factor (SFF) budget gaming systems from OEMs). Dedicated graphics card technology moves at such a rapid pace compared to motherboards that it is just not feasible to market a feature like this to enthusiasts. While they may keep the same motherboard for years, those same users will likely upgrade their graphics cards at least once to stay current. Further, with the cost of these high-end motherboards already approaching exorbitant, adding integrated GPUs that don’t mesh well with the purpose of a high end system pushes the cost higher and demand to a point that these boards just don’t seem realistic.
While Zeus was more of a powerhouse with a twist (albeit one that isn’t really feasible to market), the other motherboard – Wolverine – is a “because we can” board but one that could have an impact on the industry today. ASUS has taken its Digi+ digital power to the extreme by packing as many power phases as it could into an ATX form factor motherboard. In total, they managed to place 40 power phases onto the PCB – notice how the CPU socket had to be shifted to the right to make room!
Other features on the board include eight SATA connectors, four DIMM slots, three PCI-E 3.0 x16 slots, LGA 1155 socket, and three PCI 3.0 x1 slots. On the rear the board features four USB 2.0 ports, six USB 3.0 ports, a WiFi radio, Gigabit LAN, BIOS buttons, optical audio output, 7.1 channel analog audio output, and what looks like two eSATA ports.
Granted, I’m not suggesting that we will be seeing motherboards coming out with 40+ power phases anytime soon. I can see this influencing future designs, however. Even heavy overclockers (water and air cooling levels) don’t really /need/ 40 power phases but we could start seeing vendors put out boards with half of that and still have it be a big improvement.
What do you think of the two new ASUS concept motherboards? You can see more images of the boards over at AnandTech's gallery. Do you think they are on the right track? If not what areas do you think motherboard manufacturers need to improve?

Today we received a number of photos from ASUS that show off some upcoming hardware from their upcoming Republic of Gamers line. Except for the Xonar Phoebus (which has launched), the hardware in these photos is not yet released and ASUS has not revealed when it will be available for sale – or how much it will cost. Still, I can’t think of a better way to start the day than getting a glimpse of some shiny unreleased hardware – especially when I get to share it with you!
First up is a new Replublic of Gamers motherboard called the Maximus V Extreme. This board is similar to the mATX Maximus V GENE board that was announced recently, but the Extreme motherboard is full ATX.
While full specifications are unknown, from the photo you can see that the board has an LGA 1155 socket, making it compatible with the latest Intel Ivy Bridge processors. Further, it is sporting four DDR3 DIMM slots, five PCI-E 3.0 x16 slots, and one PCI-E 3.0 x4 slots. Other features of the board include ASUS’ Extreme Engine Digi+ II digital power control technology, power and reset buttons on the board itself, voltage check points, Lucid Virtu MVP GPU virtualization technology, and AMD CrossFireX and NVIDIA SLI support. The VRM area and southbridge area of the board is covered by large black and red heatsinks.
Rear IO includes five USB 2.0 ports (one to be used with ROG Connect), two USB 3.0 ports, an Intel-powered Gigabit LAN, HDMI, DisplayPort, optical audio output, PS/2 port, five analog audio outputs and a TOSLink connector. Additionally, the board features CMOS clear and reset buttons, a mini-PCIe + mSATA combo card, and a Republic of Gamers OC Key accessory. The OC Key plugs into the DVI port of the graphics card and provides an on-screen-display for overclocking information and voltage tweaking.
In addition to the ASUS Maximus V Extreme, the company is producing the Maximus V Forumula motherboard, which is then further available with or without the ThunderFX audio accessory. The Formula board is another socket 1155 board with a red and black color scheme that is ready for Ivy Bridge processors and multi-GPU setups (SLI or CrossFireX). The heatsinks on the formula are a little less beefy than those on the Maximus V Extreme, but the VRM heatsinks are ready to be integrated into a water cooling loop. Further features include four DDR3 DIMM slots, eight SATA connectors, three PCI-E 3.0 x16 slots, three PCI-E 3.0 x1 slots, and a single PCI-E 3.0 x4 slot.
The board also features the SupremeFX integrated sound card (which has been isolated from the rest of the board by routing the wiring through its own PCB layer) and a mini-PCI-E + mSATA combo card. One version of the motherboard also comes with the SupremeFX accessory which you can see in the photo below.
Rear IO of the Maximus V Formula motherboard includes four USB 2.0 ports (one for ROG connect), four USB 3.0 ports, an eSATA port, DisplayPort, HDMI, Intel-powered Gigabit LAN, five analog audio jacks, two optical audio outputs, and CMOS clear and reset buttons.
The Maximus Extreme V Formula comes with a device called the ThunderFX that is a high end headphone amp and DAC offering 120dB SNR, and noise cancellation technology. The included GamEQ comes with three preset profiles but also offers you a wide range of options to tweak your sound to your own desires. There is also onboard audio in the form of the SupremeFX IV audio chipset which will keep those who prefer speakers more than happy with their audio quality.
You can also see that the large anodized aluminium heatsinks have barbs for you to include them in a watercooling loop so that all components on your motherboard can be cooled without resorting to fans to move air. GameFirst II is the name ASUS has given their networking software and it is designed to examine an prioritize packets to reduce lag and ping times. It comes with both an EZ Mode as well as offering advanced options for those who know what they are doing. As we have seen on other boards, the Maximus Extreme V Formula comes with a mPCIe Combo card with dual-band Wi-Fi and Bluetooth 4.0. This board is also shattering records in Super PI 32M, 3DMark05 and Heaven to name a few.
