Qualcomm Atheros Demos 802.11ac on MSM8960

Among a bunch of interesting Krait features is a noteworthy change in connectivity that represents some of the first fruits of the Qualcomm Atheros acquisition. We touched on it in our architecture piece a while back, but that feature is inclusion of the WiFi and Bluetooth 4.0 basebands into Krait alongside the traditional combination of cellular and GPS baseband.

Just like cellular is implemented today, that design still requires external RF, but the result is a WLAN and Bluetooth baseband that get to take advantage of the SoC's 28nm process geometry. Today I caught a glimpse of both 802.11n single spatial stream, and more interestingly 802.11ac single spatial stream running on an MDP MSM8960 utilizing the on-SoC WiFi basebands and the corresponding WCN3860 external RF chip.

The demo itself was pretty self explanatory - Qualcomm was running an 802.11ac network with two MDP MSM8960s and seeing throughput of around 220-230 Mbps using their single spatial stream WCN3860 external RF. This was live on the crowded MWC show floor with other 5 GHz APs running nearby, and admittedly pretty brave to do considering other 802.11ac demos I saw at CES used wired links. The end result is pretty impressive, and it'll be interesting to see how many of OEMs choose to go this route for WiFi, Bluetooth and FM Rx/Tx (also inside WCN3860) as opposed to some of the more common discrete solutions. In addition Qualcomm had an 802.11n demo showing the same functionality.


The 802.11ac network is the middle, 80 MHz wide one in the middle, between channels 112 and 132

Just like I did at CES with Buffalo's AP demo, I also had the WiSpy DBx handy and captured another sample of the 80 MHz OFDM waveform, just to take another peak.

Microsoft Demos Windows 8 on 82-inch Touchscreen

Microsoft is talking a lot about the importance of touch input to the Windows 8 experience in everything from tablets to high-end desktops. To show just how far you can go with touch, Microsoft demonstrated a PC running Windows 8 connected to an 82-inch touchscreen that can support up to 100 touch inputs (or 10 simultaneous users).

Super Talent: Demos PCIe-based RAIDDrive upStream and RAIDDrive II SSDs

It’s a bit sad, really: SATA 6Gbps ony a couple years old and already we’re seeing SSDs push the limits of the interface. While the SATA spec will eventually be updated to support even higher bandwidths, right now companies looking for higher performance need to find other solutions. Several are moving to direct interfaces via PCIe, where even an x4 configuration can offer over three times the bandwidth of SATA 6Gbps. OCZ has the RevoDrive line, and Super Talent has their RAIDDrive. Super Talent had two new models of RAIDDrive on display at CES; the basic model is the upStream 480GB with up to four SSD controllers (SandForce 2200) while the RAIDDrive II supports up to 2TB and eight SF-2200 controllers.

Besides the RAIDDrive cards, Super Talent also had a new SF-2200 SSD brand with the latest gold level firmware on display, the TeraNova. Super Talent mentioned that many SSDs are actually out of spec in their SATA and power connector areas, with the PCB being too close to the connectors and making the SSDs unable to fit properly in hotswap drive bays; the TeraNova has the PCB cut out around the connectors so this won't be an issue.

Super Talent had some benchmarks running to demonstrate the performance potential of the three SSDs, and we grabbed some pictures of their ATTO results that you can see in the gallery. The quick summary is that the single SF-2200 controller in the TeraNova 240GB is able to hit read/write speeds of up to 545/518MB/s, which is similar to what we’ve seen on other SandForce SSDs. Move to the upStream 480GB RAIDDrive and read speeds can break the 1GB/s barrier and top out at 1021MB/s while write speeds topped out at 951MB/s. Finally, the RAIDDrive II (I’m not sure of the size, but I believe it was the 1TB model) more than doubles that on the read speeds at rates of up to 2613MB/s and writes speeds of 1637MB/s. Obviously these are sequential transfer rates, but even so you’ll need to be running workloads for more intense than desktop use before you’re really going to benefit from that much I/O performance.

One of the interesting elements of the RAIDDrive II is how Super Talent adds the SSDs to the board. Each SSD module consists of two PCBs, with the SF-2200 on one board and the NAND flash on the other. The board with the controller also contains a USB to SATA bridge chip, and the cards use USB 3.0 connections and plug into the main RAIDDrive II board. Small LEDs on the surface of the board also show which SSD modules are currently active. There’s also 64MB of RAM on the main PCB and a heatsink and small fan used to cool the RAID chip—I’m not sure what chip Super Talent is using, though I’ll try to find out.

Toshiba Demos Excite 10.1” and Concept Tablet Designs

We reviewed Toshiba’s Tegra 2-based Thrive 10.1” late last year and from a design standpoint, we were pretty disappointed with it. While elements like the removable battery, full size ports, and rubberized back cover were well done, overall the Thrive just wasn't designed as well as the leading Android tablets. It hit a more value oriented price point than higher end products like the Samsung Galaxy Tab 10.1, but even compared to more midrange tablets like the Asus Transformer, the Thrive just wasn't competitive. 

Toshiba learned a lot from their experience with the Thrive, and clearly desire to improve on their tablet designs in the future. To that end comes the new Excite 10”, a tablet that represents a dramatic step forward from the Thrive, significantly improved in almost every way. Gone are the curved edges, rubber backing, and chunky design. In its place, we find an extremely slick looking tablet that can easily compete with the cutting edge of that Android world. At 7.7mm thick, it's definitely one of the thinnest new tablets on the market. The back is flat and made of magnesium alloy, with a rounded rim around the edge of the device. Toshiba went with magnesium alloy instead of a cheaper aluminum extrude here because magnesium was lighter and more structurally rigid than a brushed aluminum casing would have been.

Spec-wise, the Excite has a 10.1" 1280x800 display with an IPS panel and Gorilla Glass covering the screen (fixing our only two complaints with the Thrive's otherwise excellent display panel). It's running TI's OMAP 4430 inside clocked at 1GHz. The higher clocked OMAP 4460 (1.5GHz) didn't fit in the thermal envelope Toshiba was shooting for with the Excite, there just wasn't enough heat being dissipated to handle the increased clock speeds. The Excite does lose the full-size ports of the Thrive, though that makes sense given that a standard size HDMI connecter is actually thicker on its own than the entire chassis of the Excite (!). The units we went hands on with had Ice Cream Sandwich installed on them, the final device may ship on either Honeycomb 3.2 or ICS depending on when the Excite hits retail as well as how long it takes Toshiba to finalize the ICS port for the Excite.

I must say, I'm absolutely in love with the industrial design of the Excite. It also feels great in hand, a completely opposite experience from the original Thrive. It's a very premium feeling device, and it has a surprisingly solid frame even with the utter lack of thickness. I'm really impressed to see how far Toshiba has come in terms of design and quality since the Thrive was shown off here last year. Toshiba envisions the Excite as a premium level product slotting above the Thrive, so the Thrive will still be sold alongside the Excite. MSRP is $529 for the 16GB and $599 for the 32GB, price points that I think are on the optimistic side given that a similarly premium design-oriented product launched recently with the Tegra 3 quad-core SoC for $499/599 for 16GB/32GB. Availability is expected close to the end of Q1, and we'll definitely have an evaluation unit to look at when it does hit market.

Gallery: Toshiba Demos Excite 10.1” and Concept Tablet Designs

Toshiba also showed off a few tablet design concepts, with 5.1", 7.7", and 13.3" form factors being shown off. The industrial design used across the entire lineup is more mainstream-oriented than the high-end Excite, though in this case that still means a relatively thin body, clean lines, and a textured plastic backing. Overall they feel pretty good, and are a significant step forward from the rather clunky Thrive design. The 7.7" model with an OLED screen especially was impressive in both in form factor as well as feel and industrial design. The 13.3" model was an interesting one in that we haven't seen a whole lot of larger tablet form factors at CES this year. I personally feel like it's something that really lends itself to being a Windows 8 tablet, but Toshiba officially says that they are still evaluating both hardware and software choices for all of the future tablet designs.

It's worth noting that all of the design concepts were running Android, and it's a distinct possibility that both Win8 and Android models will exist. Toshiba genuinely seems to be agnostic on a hardware platform level (as shown by their use of Tegra 2 in the Thrives and OMAP 4 in the Excite) so it's not difficult to believe that they don't have a silicon partner finalized yet for any of the concept tablets. These prototypes were hand built preproduction units, so build quality was obviously not something we could evaluate, but even so, I came out with high hopes for Toshiba's tablet future. Availability was expected to be Q3 onwards, with the 5.1" model with a 21:9 aspect ratio screen being made primarily for the Japanese market and probably not having high hopes for a US launch.

AMD Demos 28nm GPU Again, No Update on Availability

In order to address concerns of a difficult transition to 28nm, AMD demonstrated its next-generation 28nm GPU at IDF last month. The demo system featured a mobile variant of the next-gen GPU running DiRT 3. At the time, AMD told us to expect the GPU's release later this year. 

Since then there have been rumors of a delay until 2012, but no official update from AMD. I suspect we'll get something to that effect soon enough, but today AMD let us know that it ran another public demonstration of 28nm GPU silicon - this time in Taiwan. The demo was apparently pretty similar to last time: a mobile 28nm GPU running a game. In this case the game was Dragon Age 2, but obviously there are no performance or power details to accompany the announcement. 

AMD didn't provide any more info nor an update on the GPU's release timeframe. As with any major process transition, scaling to be able to produce mass quantities of chips on a new process can be extremely challenging. The move to 28nm is particularly rough because unlike 40nm, AMD didn't have a pipecleaner part to begin its process learnings on. How this impacted overall development remains to be seen.

Computex: Qualcomm demos dual-core mobile processors

Qualcomm has been showing off its latest dual-core mobile phone processing tech at Computex in Taipei this week.

Qualcomm's Snapdragon processors are already in many of the smartphones already on the market, including the Google Nexus One and the HTC Incredible.

Next up from Qualcomm are new dual-CPU chipsets that boost the mobile processor speed to 1.2 GHz and 1.5 GHz.

Qualcomm's snappily-titled MSM826,MSM8660 and QSD8672s should appear in a smartphone near you later this year, with a number of handset manufacturers already designing phones based around the processors.

Better gaming and video

In terms of what this means for the end user, the two cores and faster processing clout will generally mean better gaming and multimedia output on your smartphone.

Qualcomm's new chipsets also include a graphics processing unit (GPU) with 2D and 3D acceleration engines, 1080p video encoding and decoding capabilities and an integrated GPS.

"Qualcomm today announced the extension of Adobe Flash Player capabilities and full Web browsing to the mass market segment of Qualcomm-enabled smartphones," reads the company's Computex release.

"In addition, Qualcomm will enable high-definition (HD) video playback of Flash-based content on mid-tier and higher end Snapdragon-powered smartphones and tablets."

So better, faster, smoother games and video on our mobile phones, you say? It's hard to really argue with that logic…

Adobe partnership

"Qualcomm and Adobe have developed a lasting relationship driven by both sides' desire to bring an exceptional Web experience throughout all tiers of smart mobile devices," adds Rob Chandhok, president of Qualcomm Internet Services.

"Bringing Flash Player to the mass market segment of smartphones and HD video to higher end smartphones with Qualcomm's processors will expand the scope of possibilities on a mobile device."

Finally, Kouji Kodera, chief product officer at HTC, chips in with: "Software continues to be critical to the mobile user experience, and HTC is committed to bringing Flash content from the Internet to all types of devices, including smartphones and tablets."

AMD demos new 9-series chipset

Chip designer AMD showed off its latest Trinity APU and new 9-series chipset to an eager crown of tech journalists and industry punters at Computex in Taipei this week.

AMD's new 9-series chipset is a key part of the firm's Scorpius desktop platform, featuring 8-core Zambezi processors built on the Bulldozer core, according to AMD product group general manager, Rick Bergman.

Graphics grunt

In addition to being compatible with AMD's forthcoming CPUs, the 9-series chipset supports up to 1,866MHz DDR3 RAM and is able to power up to four Crossfire X graphics cards.

AMD is also promoting the I/O capabilities of its 9-series chipset, which the company claims can provide up to 14 USB 2.0 ports and up to six SATA 6Gbps ports.

The new chipsets are available immediately with AMD's latest motherboards to be on sale later in June. Zambezi CPUs will be available "late Summer".

"As consumer appetites for more compelling, lifelike visual experiences increase, there is greater need for high performance, smooth, vibrant graphics as well as unparalleled computing power," says AMD product marketing director, John Taylor.

"From tablets to desktops, AMD is making powerful computing accessible to everyone."
