Sentences containing the words "Hewlett-Packard" and "tablet" can end in a question mark, an exclamation mark, or a period on occasion. The gigantic multinational technology company tried to own a whole mobile operating system with their purchase of Palm and abandoned those plans just as abruptly with such a successful $99 liquidation of $500 tablets, go figure, that they to some extent did it twice. The operating system was open sourced and at some point LG swooped in and bought it, minus patents, for use in Smart TVs.
So how about that Android?
The floodgates are open on Tegra 4 with HP announcing their SlateBook x2 hybrid tablet just a single day after NVIDIA's SHIELD move out of the projects. The SlateBook x2 uses the Tegra 4 processor to power Android 4.2.2 Jellybean along with the full Google experience including the Google Play store. Along with Google Play, the SlateBook and its Tegra 4 processor are also allowed in TegraZone and NVIDIA's mobile gaming ecosystem.
As for the device itself, it is a 10.1" Android tablet which can dock into a keyboard for extended battery life, I/O ports, and well, a hardware keyboard. You are able to attach this tablet to a TV via HDMI along with the typical USB 2.0, combo audio jack, and a full-sized SD card slot; which half any given port is available through is anyone's guess, however. Wirelessly, you have WiFi a/b/g/n and some unspecified version of Bluetooth.
The raw specifications list follows:
NVIDIA Tegra 4 SoC
- ARM Cortex A15 quad core @ 1.8 GHz
- 72 "Core" GeForce GPU @ ~672MHz, 96 GFLOPS
- 2GB DDR3L RAM ("Starts at", maybe more upon customization?)
- 64GB eMMC SSD
- 1920x1200 10.1" touch-enabled IPS display
- HDMI output
- 1080p rear camera, 720p front camera with integrated microphone
- 802.11a/b/g/n + Bluetooth (4.0??)
- Combo audio jack, USB 2.0, SD Card reader
- Android 4.2.2 w/ Full Google and TegraZone experiences.
If this excites you, then you only have to wait until some point in August; you will also, of course, need to wait until you save up about $479.99 plus tax and shipping.

The plural of anecdote is not data but The Tech Report does make some good points about how the tablet may push the notebook out of the market, or at least reduce its market share significantly. Unless you are buying a gaming laptop, in its self a niche market, there are many qualities about tablets that make them an attractive alternative, ranging from the lack of crumbs accumulating in the keyboard to all day battery life. If you do not game or have programs you use which actually need the processing power of a full x86 processor then you will never even notice the reduction in processing power that comes from moving to an ARM or other low powered processor. There is still no way that it is going to replace desktops whose users actually need real processing power ... or triple monitors.
"Earlier this week, Gartner reported that PC shipments shrank by almost 5% last quarter. The firm pinned the blame on users relinquishing their PCs for daily use. As enthusiasts, we may find it hard to imagine folks ditching their computers for comparatively limited tablets. However, I have some pretty convincing anecdotal evidence that lends weight to Gartner's thesis."

Intel is a yearly presence at CES and typically have a few interesting things to talk about. Last year we got to see Will.I.Am on stage telling us all about how the Ultrabook has changed his artistic life. Oddly enough, things have not changed dramatically for the company. Ultrabooks have inherited the latest Ivy Bridge processors which were released last Spring. Medfield is still the primary cell phone processor for Intel.
The first area they covered is the cellphone market. Medfield is still the go-to processor and Intel claims that it has better performance and battery life than even the latest Qualcomm products. Intel is introducing a new reference phone for emerging markets around the world codenamed Lexington. Based on the Z2420 and the XMM6265 modem, this budget smartphone will be Android based with certain optimizations instituted by Intel in collaboration with Google.
Intel has achieved more wins throughout the next few months. Acer, Safaricom, and Lava will all be announcing new smart phones based on Intel silicon. Details of these products will be released later in the quarter.
Medfield will be replaced by Clover Tail+ and then further on with their next gen 22 nm product.

AMD launched a new APU today meant for tablets and other mobile devices. The new Z-60 Accelerated Processing Unit (APU) is now the company’s lowest power APU processor. AMD is primarily pushing this chip as the best choice for tablets as thin as 10mm that are capable of running Windows 8.
The Z-60 APU supports AMD’s Start Now and AppZone technologies for fast boot and resume times and application repository respectively. AMD has stated that it identified a gap between low performance and high priced mobile devices, and believes the Z-60 APU fills that void. AMD Corporate Vice President of Ultra-Low Power Products Steve Belt further stated the following:
“Tablet users seeking an uncompromised experience for both creating and consuming content on the Microsoft Windows 8 platform now have a performance-driven, affordable option with the AMD Z-60 APU.”
Interestingly, AMD has managed to bring the TDP of the new Z-60 lower than the previous generation without sacrificing hardware or needing a new manufacturing process. While the Z-01 is part of the Brazos platform (codename Desna), the new Z-60 is codenamed Hondo and part of the Brazos-T platform, which involves several tweaks to the design to get more power efficiency.
The Z-60 has two Bobcat CPU cores clocked at 1GHz, 1MB L2 cache, and a Radeon HD 6250 GPU with 80 cores. This APU has a TDP of 4.5W, which is a noteable decrease from the Z-01's 5.9W TDP when you consider that this chip is going to be used in a battery powered, mobile device. In fact, with a Z-60 APU, AMD is claiming up to eight hours of batery life. Further, thanks to the integrated HD 6250 GPU, the Z-60 can support Direct X 11, OpenGL 4.1, and OpenCL 1.1 graphics technologies.
|CPU Cores||CPU Clockspeed||L2 Cache||Radeon GPU||GPU Cores||TDP||USB Support|
|Z-60||2||1 GHz||1 MB||HD 6250||80||4.5W||3.0|
|Z-01 (previous generation)||2||1 GHz||1 MB||HD 6250||80||5.9W||2.0|
AMD has announced that the Z-60 APU is shipping now to its OEM customers. The company expects that consumers should see products using the new processor as soon as the end of this year.

Tagged: WOA, windows 8, tablets, nokia, microsoft, arm
Earlier this year we heard talk of several planned Windows On ARM tablets that would run the upcoming Windows 8 operating system, and now more planned tablets have emerged. Asus is planning to release four Windows 8 tablets (two WOA versions), and according to Digitimes, Nokia will be joining the fray with their own WOA tablets.
Allegedly, Nokia will launch a 10" ARM tablet powered by Qualcomm's dual core System on a Chip (SoC) processor. The tablet will run the Windows on ARM version of Windows 8, and their sources have expressed that the Nokia tablet will further fuel the mobile tablet market and provide healthy competition for the iPad juggernaut.
Further, according to "sources at upstream component suppliers," Nokia will be outsourcing the manufacturing of their Windows 8 tablet to Compal Electronics. Also, the sources have stated that the first production batch will consist of 200,000 units.
Don't forget to check out our guide on virtualizing Windows 8 to get an idea of how the new interface works. More information on the Windows On ARM front as it develops.

Tagged: ray tracing, tablet, tablets, knight's ferry, Intel
Intel looks to bring ray-tracing from their Many Integrated Core (Intel MIC) architecture to your tablet… by remotely streaming from a server loaded with one or more Knight’s Ferry cards.
The anticipation of ray-tracing engulfed almost the entirety of 3D video gaming history. The reasonable support of ray-tracing is very seductive for games as it enables easier access to effects such as global illumination, reflections, and so forth. Ray-tracing is well deserved of its status as a buzzword.
Render yourself in what Knight’s Ferry delivered… with scaling linearly and ray-traced Wolfenstein

Obviously Intel would love to make headway into the graphics market. In the past Intel has struggled to put forth an acceptable offering for graphics. It is my personal belief that Intel did not take graphics seriously when they were content selling cheap GPUs to be packed in with PCs. While the short term easy money flowed in, the industry slipped far enough ahead of them that they could not just easily pounce back into contention with a single huge R&D check.
Intel obviously cares about graphics now, and has been relentless at their research into the field. Their CPUs are far ahead of any competition in terms of serial performance -- and power consumption is getting plenty of attention itself.
Intel has long ago acknowledged the importance of massively parallel computing but was never quite able to bring products like Larabee against anything the companies they once ignored could retaliate with. This brings us back to ray-tracing: what is the ultimate advantage of ray-tracing?
Ray-tracing is a dead simple algorithm.
A ray-trace renderer is programmed very simply and elegantly. Effects are often added directly and without much approximation necessary. No hacking around is required in the numerous caveats within graphics APIs in order to get a functional render on screen. If you can keep throwing enough coal on the fire, it will burn without much effort -- so to speak. Intel just needs to put a fast enough processor behind it, and away they go.
Throughout the article, Daniel Pohl has in fact discussed numerous enhancements that they have made to their ray-tracing engine to improve performance. One of the most interesting improvements is their approach to antialiasing. If the rays from two neighboring pixels strike different meshes or strike the same mesh at the point of a sharp change in direction, denoted by color, between pixels then they are flagged for supersampling. The combination of that shortcut with MLAA will also be explored by Intel at some point.
A little behind-the-scenes trickery...
Screenshot from Intel Blogs.
Intel claims that they were able to achieve 20-30 FPS at 1024x600 resolutions streaming from a server with a single Knight’s Ferry card installed to an Intel Atom-based tablet. They were able to scale to within a couple percent of theoretical 8x performance with 8 Knight’s Ferry cards installed.
I very much dislike trusting my content to online streaming services as I am an art nut. I value the preservation of content which just is not possible if you are only able to access it through some remote third party -- can you guess my stance on DRM? That aside, I understand that Intel and others will regularly find ways to push content to where there just should not be enough computational horsepower to accept it.
Ray-tracing might be Intel’s attempt to circumvent all of the years of research that they ignored with conventional real-time rendering technologies. Either way, gaming engines are going the way of simpler rendering algorithms as GPUs become more generalized and less reliant on fixed-function hardware assigned to some arbitrary DirectX or OpenGL specification.
Intel just hopes that they can have a compelling product at that destination whenever the rest of the industry arrives.

This year is a big one for smaller silicon manufacturing processes with Intel's 22nm Ivy Bridge, and NVIDIA and AMD moving to 28nm GPU processes. According to a report on VR-Zone, NVIDIA is already planning their next move for Tegra, including a die shrink to 28nm.
They managed to get their hands on a road map (shown below) for NVIDIA's Tegra SoC (system on a chip) lineup that extends into 2013. With Tegra 3, NVIDIA began by sampling the chip to Asus and the Transformer Prime. After that success, other partners and devices are starting to pick up the mobile chip, and they expect the situation to be the same for future Tegra iterations.
They company allegedly taped out a Tegra 4 (T40) SoC at the end of December 2011, and is starting to sample it to OEM partners to find someone to do a Tegra 3 like launch, with one device/platform to debut first and others to follow in later months.
The Tegra 4 chip is code named "Wayne" and will be comprised of multiple ARM Cortex A15 CPU cores and a new GPU on a 28nm process. The company alos plans to show off a dual core 28nm SoC that uses two Cortex A15 CPU cores, a revamped GPU, and an Icera 4G LTE radio at Mobile World Congress 2013 next year.
Further, the roadmap details a new Tegra 3 chip that is intended to be used with Windows on ARM powered notebooks and tablets. While the new Tegra 3 (T35) SoC will not be a die shrink, it will have higher clock speeds due to less restrictions placed on the maximum TDP (thermal design power) allowed for the devices. VR-Zone estimates that the T35 chips will run somewhere between 1.6 GHz and 1.7 GHz.
Currently there are some incompatibilities with Tegra and 4G LTE radios which has caused some LTE devices to go with Qualcomm SoCs, so it is good to see NVIDIA working on improving compatibility and then integrating the basebands into their future SoCs to rectify the issue.
As far as this year is concerned, we should see the updated Tegra 3 chip and a new version of Tegra 2 that integrates a Icera 4G LTE baseband. The Wayne and Grey chips will likely not be released until 2013 at the earliest. The expanded Tegra portfolio should help them to gain some market share, though exactly how much remains to be seen.
