NVIDIA has released their updated version of the SHIELD tablet with a new name, but very little has changed other than the name (now the SHIELD tablet K1) and the price - now $100 less expensive at $199.99.
The SHIELD tablet K1 (pictured case and controller are not included)
Under the hood the 8-inch Android-powered tablet is identical to its predecessor, with the quad-core Tegra K1 processor with its 192 CUDA core GPU powering the gaming action on the 1920x1200 display. The controller is still a separate $59.99 purchase, but of course this is not required to use the tablet.
Here are full specs from NVIDIA:
- Processor: NVIDIA Tegra K1 192 core Kepler GPU (2.2 GHz ARM Cortex A15 CPU with 2 GB RAM)
- Display: 8-inch 1920x1200 multi-touch full-HD display
- Audio: Front-facing stereo speakers with built-in microphone
- Storage: 16 GB
- Wireless: 802.11n 2x2 MIMO 2.4 GHz and 5 GHz Wi-Fi; Bluetooth 4.0 LE, GPS/GLONASS
- I/O: Mini-HDMI output, Micro-USB 2.0, MicroSD slot, 3.5 mm stereo headphone jack with microphone support
- Motion Sensors: 3-axis gyro, 3-axis accelerometer, 3-axis compass
- Cameras: Front, 5MP HDR; Back, 5MP auto-focus HDR
- Battery: 19.75 Watt Hours
- Dimensions: Weight, 12.6 oz (356 g); H x W x D: 8.8 in (221 mm) x 5.0 in (126 mm) x 0.36 in (9.2 mm)
- Operating System: Android Lollipop
- Gaming Features: SHIELD controller compatible, GeForce NOW cloud gaming service, Console Mode, NVIDIA ShadowPlay
- Included Apps: Google Play, NVIDIA SHIELD Hub, Fallout Shelter, NVIDIA Dabbler, Squid, Twitch
This update really comes down to price, as NVIDIA is being more aggressive about the adoption of their gaming tablet with the new MSRP. This doesn't come without some concessions, however, as the SHIELD tablet K1 ships without any accessories (no USB cable or charger). It's a move remienscent of Nintendo with the "New 3DS XL", which also shipped without a charger, and the standard micro-USB connection should be readily at hand for most of the target audience.
The question of course must be, is this now a more compelling product at $199? It does make the controller seem a bit more affordable considering the bundle will now run $260 - $40 below the previous tablet-only price. Time will tell (and of course you can let us know in the comments below!).
NVIDIA is selling the SHIELD tablet K1 directly from their web store, and it's already on Amazon for the same $199.99 price.

Now that you have read Josh's article detailing the new Maxwell based Tegra X1 you might be wondering what products it could appear in, apart from an updated Shield. DigiTimes has a theory based on the current lawsuits against Samsung Electronics and Qualcomm which claim that those companies have infringed several fairly basic patents which NVIDIA holds including object texture, lighting, shading, GPGPU and vertex operators. If the lawsuits were successful the cost of purchasing chips from those two competitors could increase making the new Tegra X1 a more financially attractive product, even with the associated costs of changing hardware. If the power and performance expectations of the new mobile Maxwell chip are met then NVIDIA's new chip could also become a more attractive alternative for vendors as it could well outpace the next generation of chips from Qualcomm and Samsung regardless of the outcome of the lawsuits. If you like speculation you can peek in at DigiTimes posting here.
"To find new outlets for its GPU business, Nvidia has started licensing its GPU architecture to other application processor (AP) designers. Kepler was the first GPU platform Nvidia offered for licensing and its latest-generation Maxwell will also become available for licensing later."

NVIDIA's Tegra X1
NVIDIA seems to like begin on a one year cycle with their latest Tegra products. Many years ago we were introduced to the Tegra 2, and the year after that the Tegra 3, and the year after that the Tegra 4. Well, NVIDIA did spice up their naming scheme to get away from the numbers (not to mention the potential stigma of how many of those products actually made an impact in the industry). Last year's entry was the Tegra K1 based on the Kepler graphics technology. These products were interesting due to the use of the very latest, cutting edge graphics technology in a mobile/low power format. The Tegra K1 64 bit variant used two “Denver” cores that were actually designed by NVIDIA.
While technically interesting, the Tegra K1 series have made about the same impact as the previous versions. The Nexus 9 was the biggest win for NVIDIA with these parts, and we have heard of a smattering of automotive companies using Tegra K1 in those applications. NVIDIA uses the Tegra K1 in their latest Shield tablet, but they do not typically release data regarding the number of products sold. The Tegra K1 looks to be the most successful product since the original Tegra 2, but the question of how well they actually sold looms over the entire brand.
So why the history lesson? Well, we have to see where NVIDIA has been to get a good idea of where they are heading next. Today, NVIDIA is introducing the latest Tegra product, and it is going in a slightly different direction than what many had expected.

Along with the announcement of the Google Nexus 6 phone, Google is also announcing a new tablet, the Nexus 9. Sporting an 8.9-in IPS screen with a 2048x1536 resolution (4:3 standing strong!), a 6700 mAh battery as well as the new Android Lollipop operating system, perhaps the most interesting specification is that it is built around NVIDIA's Tegra K1 SoC. Specifically, the 64-bit version based on the dual-core custom built Denver design, marking that architectures first release in shipping product.
UPDATE: Amazon.com has the Google Nexus 9 up for pre-order in both 16GB and 32GB capacities!
Tegra K1 using 64-bit Denver cores are unique in that it marks the first time NVIDIA has not used off-the-shelf cores from ARM in it's SoC designs. We also know, based on Tim's news post on PC Perspective in August, that the architecture is using a 7-way superscalar design and actually runs a custom instruction set that gets translated to ARMv8 in real-time.
A software layer and 128MB cache enhance the Dynamic Code Optimization technology by allowing the processor to examine and optimize the ARM code, convert it to the custom instruction set, and further cache the converted microcode of frequently used applications in a cache (which can be bypassed for infrequently processed code). Using the wider execution engine and Dynamic Code Optimization (which is transparent to ARM developers and does not require updated applications), NVIDIA touts the dual Denver core Tegra K1 as being at least as powerful as the quad and octo-core packing competition.
It is great news for NVIDIA that Google is using this version of the Tegra K1 (can we please just get a different name for this version of the chip) as it indicates Google's commitment to the architecture in Android going forward, opening doors for the parts integration with even more devices with other hardware vendors moving forward.
More than likely built by HTC, the Nexus 9 will ship in three different colors (black, white and beige) and has a lot of callbacks to the Nexus 7, one of if not THE most popular Android tablet on the market. The tablet has front-facing speakers which should make it good for headphone-free media consumption when necessary. You'll be able put the Nexus 9 into a working mode easily with a new magnetically attached keyboard dock, similar to the iPad accessories widely available.
The Nexus 9 weighs in at 425g (the iPad Air weighs 478g), will have 16GB and 32GB capacity options, going up for preorder on 10/17 and shipping by 11/03. Google will sell both a 32GB Wi-Fi and 32GB LTE model with the LTE version (as well as the Sand color) shipping "later this year." Pricing is set at $399 for the 16GB model, $479 for the 32GB model and $599 for the 32GB+LTE version. That is quite a price hike for LTE capability and the $80 gap between the 16GB and 32GB options is annoying as well.

The Nexus line is due for an update, with each product being released for at least a year. They are devices which embody Google's vision... for their own platform. You can fall on either side of that debate, whether it guides OEM partners or if it is simply a shard the fragmentation issue, if you even believe that fragmentation is bad, but they are easy to recommend and a good benchmark for Android.
We are expecting a few new entries in the coming months, one of which being the Nexus 9. Of note, it is expected to mark the return of HTC to the Nexus brand. They were the launch partner with the Nexus One and then promptly exited stage left as LG, Samsung, and ASUS performed the main acts.
We found this out because NVIDIA spilled the beans on their lawsuit filing against Qualcomm and Samsung. Apparently, "the HTC Nexus 9, expected in the third quarter of 2014, is also expected to use the Tegra K1". It has since been revised to remove the reference. While the K1 has a significant GPU to back it up, it will likely be driving a very high resolution display. The Nexus 6 is expected to launch at around the same time, along with Android 5.0 itself, and the 5.2-inch phone is rumored to have a 1440p display. It seems unlikely that a larger, tablet display will be lower resolution than the phone it launches alongside -- and there's not much room above it.
The Google Nexus 9 is expected for "Q3".
NVIDIA Reveals 64-bit Denver CPU Core Details, Headed to New Tegra K1 Powered Devices Later This Year
Subject: Processors | August 12, 2014 - 05:06 AM | Tim Verry
Tagged: tegra k1, project denver, nvidia, Denver, ARMv8, arm, Android, 64-bit
During GTC 2014 NVIDIA launched the Tegra K1, a new mobile SoC that contains a powerful Kepler-based GPU. Initial processors (and the resultant design wins such as the Acer Chromebook 13 and Xiaomi Mi Pad) utilized four ARM Cortex-A15 cores for the CPU side of things, but later this year NVIDIA is deploying a variant of the Tegra K1 SoC that switches out the four A15 cores for two custom (NVIDIA developed) Denver CPU cores.
The custom 64-bit Denver CPU cores use a 7-way superscalar design and run a custom instruction set. Denver is a wide but in-order architecture that allows up to seven operations per clock cycle. NVIDIA is using a custom ISA and on-the-fly binary translation to convert ARMv8 instructions to microcode before execution. A software layer and 128MB cache enhance the Dynamic Code Optimization technology by allowing the processor to examine and optimize the ARM code, convert it to the custom instruction set, and further cache the converted microcode of frequently used applications in a cache (which can be bypassed for infrequently processed code). Using the wider execution engine and Dynamic Code Optimization (which is transparent to ARM developers and does not require updated applications), NVIDIA touts the dual Denver core Tegra K1 as being at least as powerful as the quad and octo-core packing competition.
Further, NVIDIA has claimed at at peak throughput (and in specific situations where application code and DCO can take full advantage of the 7-way execution engine) the Denver-based mobile SoC handily outpaces Intel’s Bay Trail, Apple’s A7 Cyclone, and Qualcomm’s Krait 400 CPU cores. In the results of a synthetic benchmark test provided to The Tech Report, the Denver cores were even challenging Intel’s Haswell-based Celeron 2955U processor. Keeping in mind that these are NVIDIA-provided numbers and likely the best results one can expect, Denver is still quite a bit more capable than existing cores. (Note that the Haswell chips would likely pull much farther ahead when presented with applications that cannot be easily executed in-order with limited instruction parallelism).
NVIDIA is ratcheting up mobile CPU performance with its Denver cores, but it is also aiming for an efficient chip and has implemented several power saving tweaks. Beyond the decision to go with an in-order execution engine (with DCO hopefully mostly making up for that), the beefy Denver cores reportedly feature low latency power state transitions (e.g. between active and idle states), power gating, dynamic voltage, and dynamic clock scaling. The company claims that “Denver's performance will rival some mainstream PC-class CPUs at significantly reduced power consumption.” In real terms this should mean that the two Denver cores in place of the quad core A15 design in the Tegra K1 should not result in significantly lower battery life. The two K1 variants are said to be pin compatible such that OEMs and developers can easily bring upgraded models to market with the faster Denver cores.
For those curious, In the Tegra K1, the two Denver cores (clocked at up to 2.5GHz) share a 16-way L2 cache and each have 128KB instruction and 64KB data L1 caches to themselves. The 128MB Dynamic Code Optimization cache is held in system memory.
Denver is the first (custom) 64-bit ARM processor for Android (with Apple’s A7 being the first 64-bit smartphone chip), and NVIDIA is working on supporting the next generation Android OS known as Android L.
The dual Denver core Tegra K1 is coming later this year and I am excited to see how it performs. The current K1 chip already has a powerful fully CUDA compliant Kepler-based GPU which has enabled awesome projects such as computer vision and even prototype self-driving cars. With the new Kepler GPU and Denver CPU pairing, I’m looking forward to seeing how NVIDIA’s latest chip is put to work and the kinds of devices it enables.
Are you excited for the new Tegra K1 SoC with NVIDIA’s first fully custom cores?

Today Acer unveiled a new Chromebook powered by an NVIDIA Tegra K1 processor. The aptly-named Chromebook 13 is 13-inch thin and light notebook running Google’s Chrome OS with up to 13 hours of battery life and three times the graphical performance of existing Chromebooks using Intel Bay Trail and Samsung Exynos processors.
The Chromebook 13 is 18mm thick and comes in a white plastic fanless chassis that hosts a 13.3” display, full size keyboard, trackpad, and HD webcam. The Chromebook 13 will be available with a 1366x768 or 1920x1080 resolution panel depending on the particular model (more on that below).
Beyond the usual laptop fixtures, external I/O includes two USB 3.0 ports, HDMI video output, a SD card reader, and a combo headphone/mic jack. Acer has placed one USB port on the left side along with the card reader and one USB port next to the HDMI port on the rear of the laptop. Personally, I welcome the HDMI port placement as it means connecting a second display will not result in a cable invading the mousing area should i wish to use a mouse (and it’s even south paw friendly Scott!).
The Chromebook 13 looks decent from the outside, but it is the internals where the device gets really interesting. Instead of going with an Intel Bay Trail (or even Celeron/Core i3), Acer has opted to team up with NVIDIA to deliver the world’s first NVIDIA-powered Chromebook.
Specifically, the Chromebook 13 uses a NVIDIA Tegra K1 SoC, up to 4GB RAM, and up to 32GB of flash storage. The K1 offers up four A15 CPU cores clocked at 2.1GHz, and a graphics unit with 192 Kepler-based CUDA cores. Acer rates the Chromebook 13 at 11 hours with the 1080p panel or 13 hours when equipped with the 1366x768 resolution display. Even being conservative, the Chromebook 13 looks to be the new leader in Chromebook battery life (with the previous leader claiming 11 hours).
A graph comparing WebGL performance between the NVIDIA Tegra K1, Intel (Bay Trail) Celeron N2830, Samsung Exynos 5800, and Samsung Exynos 5250. Results courtesy NVIDIA.
The Tegra K1 is a powerful little chip, and it is nice to see NVIDIA get a design win here. NVIDIA claims that the Tegra K1, which is rated at 326 GFLOPS of compute performance, offers up to three times the graphics performance of the Bay Trail N2830 and Exynos 5800 SoCs. Additionally, the K1 reportedly uses slightly less power and delivers higher multi-tasking performance. I’m looking forward to seeing independent reviews in this laptop formfactor and hoping that the chip lives up to its promises.
The Chromebook 13 is currently up for pre-order and will be available in September starting at $279. The Tegra K1-powered laptop will hit the United States and Europe first, with other countries to follow. Initially, the Europe roll-out will include “UK, Netherlands, Belgium, Denmark, Sweden, Finland, Norway, France, Germany, Russia, Italy, Spain, South Africa and Switzerland.”
Acer is offering three consumer SKUs and one education SKU that will be exclusively offering through a re-seller. Please see the chart below for the specifications and pricing.
|Acer Chromebook 13 Models||System Memory (RAM)||Storage (flash)||Display||Price MSRP|
|CB5-311-T9B0||2GB||16GB||1920 x 1080||$299.99|
|CB5-311-T1UU||4GB||32GB||1920 x 1080||$379.99|
|CB5-311-T7NN - Base Model||2GB||16GB||1366 x 768||$279.99|
|Educational SKU (Reseller Only)||4GB||16GB||1366 x 768||$329.99|
Intel made some waves in the Chromebook market earlier this year with the announcement of several new Intel-powered Chrome devices and the addition of conflict-free Haswell Core i3 options. It seems that it is now time for the ARM(ed) response. I’m interested to see how NVIDIA’s newest model chip stacks up to the current and upcoming Intel x86 competition in terms of graphics power and battery usage.
As far as Chromebooks go, if the performance is at the point Acer and NVIDIA claim, this one definitely looks like a decent option considering the price. I think a head-to-head between the ASUS C200 (Bay Trail N2830, 2GB RAM, 16GB eMMC, and 1366x768 display at $249.99 MSRP) and Acer Chromebook 13 would be interesting as the real differentiator (beyond aesthetics) is the underlying SoC. I do wish there was a 4GB/16GB/1080p option in the Chromebook 13 lineup though considering the big price jump to get 4GB RAM (mostly as a result of the doubling of flash) in the $379.99 model at, say, $320 MSRP.

A Tablet and Controller Worth Using
An interesting thing happened a couple of weeks back, while I was standing on stage at our annual PC Perspective Hardware Workshop during Quakecon in Dallas, TX. When NVIDIA offered up a SHIELD (now called the SHIELD Portable) for raffle, the audience cheered. And not just a little bit, but more than they did for nearly any other hardware offered up during the show. That included motherboards, graphics card, monitors, even complete systems. It kind of took me aback - NVIDIA SHIELD was a popular brand, a name that was recognized, and apparently, a product that people wanted to own. You might not have guessed that based on the sales numbers that SHIELD has put forward though. Even though it appeared to have a significant mind share, market share was something that was lacking.
Today though, NVIDIA prepares the second product in the SHIELD lineup, the SHIELD Tablet, a device the company hopes improves on the idea of SHIELD to encourage other users to sign on. It's a tablet (not a tablet with a controller attached), it has a more powerful SoC that can utilize different APIs for unique games, it can be more easily used in a 10-ft console mode and the SHIELD specific features like Game Stream are included and enhanced.
The question of course though is easy to put forward: should you buy one? Let's explore.
The NVIDIA SHIELD Tablet
At first glance, the NVIDIA SHIELD Tablet looks like a tablet. That actually isn't a negative selling point though, as the SHIELD Tablet can and does act like a high end tablet in nearly every way: performance, function, looks. We originally went over the entirety of the tablet's specifications in our first preview last week but much of it bears repeating for this review.
The SHIELD Tablet is built around the NVIDIA Tegra K1 SoC, the first mobile silicon to implement the Kepler graphics architecture. That feature alone makes this tablet impressive because it offers graphics performance not seen in a form factor like this before. CPU performance is also improved over the Tegra 4 processor, but the graphics portion of the die sees the largest performance jump easily.
A 1920x1200 resolution 7.9-in IPS screen faces the user and brings the option of full 1080p content lacking with the first SHIELD portable. The screen is bright and crisp, easily viewable in bring lighting for gaming or use in lots of environments. Though the Xiaomi Mi Pad 7.9 had a 2048x1536 resolution screen, the form factor of the SHIELD Tablet is much more in line with what NVIDIA built with the Tegra Note 7.
