Guessing at NVIDIA's future licensing

Subject: General Tech | January 5, 2015 - 04:06 PM |
Tagged: Tegra X1, tegra k1, tegra, nvidia, maxwell, speculation

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.

IMG_0929.JPG

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.

Tonight at 8pm PT / 11pm ET NVIDIA will be hosting its annual press conference from CES 2015. While I fully expect the majority of the information to be on Tegra-related products, there is a chance they could slip in some GeForce products as well. I leave nothing past NVIDIA with a 2 hour window.

You can watch the live stream of the event right here and I am going to be live blogging from the event as well, pending Internet capability inside the conference room.

Testing Updated NVIDIA GRID on SHIELD Tablet with Lollipop

Subject: Mobile | November 18, 2014 - 10:40 AM |
Tagged: tegra, shield tablet, shield, nvidia, grid

In December of last year we took NVIDIA's GRID technology through some testing and discussed our experiences in text and video. At that point you were able to play 8 specific games under the guise of a beta program. The experience was pretty good and a definite improvement over my first attempt at streaming games (OnLive). Here is what I wrote last year:

Overall my experience with the first beta of GRID was very positive including both latency and image quality.  Yes, there were definitely times when we got a lot of macro-blocking due to bandwidth hiccups, but they were infrequent.  You could tell pretty much anytime there was motion on the screen that you were watching a video rather than native gameplay, but I think the effect is much less apparent now than it was when I first tried services like OnLive.

Input latency is also definitely seen, and was most evident in my testing with Street Fighter IV.  You can even see some of it in our video embedded on this post.  That is something that NVIDIA claims to have really optimized for with their integrated H.264 encoding on the server GPUs, but getting more servers in more locations will help tremendously moving forward.

Today, along with the official roll out of the Android 5.0 Lollipop software update for the SHIELD Tablet, the NVIDIA GRID service goes into official release. What exactly that means is up in the air, as the service is still set to be free to all SHIELD and SHIELD Tablet users through June 2015. What I can tell you is that the quality of the experience has been improved and the game selection has expanded quite a bit, with more to come.

Setup of GRID is much easier now, as long as you have the appropriate hardware to get GRID service up and running. That means a SHIELD Portable or SHIELD Tablet with SHIELD Controller. These are the items that stand out beyond that:

  • Internet connection with at least a 10 Mbps download speed
  • Home network with 60 ms or less ping time to a GRID server
  • NVIDIA GameStream-ready 5 GHz Wi-Fi router

I have asked for the location of the GRID servers geographically, as that will definitely be a factor in your ability to get the appropriate 60 ms or lower ping time. (UPDATE: NVIDIA tells me that the current locations are Oregon and Virginia.) The list of compatible routers has been growing over the last year as well including some from Netgear, D-Link, Buffalo and ASUS. If you don't already have one of these routers, you can still TRY to use the GRID service but it won't be officially supported by NVIDIA.

LEGO Batman 2

The games available to play on NVIDIA GRID has expanded as well.

  • Alan Wake's American Nightmare
  • Astebreed
  • Batman: Arkham Asylum
  • Batman: Arkham City
  • Borderlands
  • Borderlands 2
  • Brutal Legend
  • Darksiders
  • Darksiders 2
  • Dead Island
  • Dirt 2
  • LEGO Batman 2
  • LEGO Marvel Super Heroes
  • Race Driver GRID
  • Strike Suit Zero
  • Saints Row: The Third
  • Street Fighter X Tekken
  • The Witcher 2: Assassins of Kings
  • Trine 2
  • Ultra Street Fighter IV

There are some great titles in here including Borderlands, Saint's Row, The Witcher 2, the Batman games, etc. and if you haven't played them before then getting access to them for free is awesome. Even better, NVIDIA has committed to adding one new game each week between now and June of next year. NVIDIA upgraded the login / account system to move away from being associated solely with the device and instead uses your Google account login information to register save data.

games1.jpg

In terms of game quality and gaming experience, I would say that GRID continues to improve. I spent some time with DiRT 2, LEGO Batman 2, Street Fighter IV and The Witcher 2 and in all cases the games looked great, with very little macro-blocking or stutter. We tested on both our office connection (1.0 Gbps fiber) and my home connection (30 Mbps cable) and the results were pretty much the same.

For those concerned with latency of input, there is definitely still some there, most apparent in fighting game like Street Fighter IV. With Borderlands and Borderlands 2 being the only FPS games in the collection, you could likely assume that the twich-style actions of these types of shooters would be most affected. Titles like Street Fighter IV and DiRT 2, for those of us that don't consider ourselves experts, can be adjusted to; you can make your mind compensate for the added input differences of playing games locally.

DiRT 2

With the SHIELD Tablet, another possible use for GRID is to play these streaming games on your TV. The tablet itself has an HDMI output and is capable of outputting 1080p to your big screen. With the SHIELD Controller you can get a true couch gaming experience with GRID; I am looking forward to showing this to my niece and nephews over the Thanksgiving holiday and getting some reactions and feedback.

The Witcher 2

The other big news today is the release of SHIELD Tablet software update 2.0 that includes Android 5.0 and Lollipop, updates for the new GRID release and an updated NVIDIA Dabbler V2.0 program. We'll have more thoughts on that software update very soon but you can get more details on the upgrades Lollipop provides for NVIDIA's tablet right here.

Google Nexus 9 Powered by NVIDIA Tegra K1, Denver 64-bit SoC

Subject: Mobile | October 15, 2014 - 01:10 PM |
Tagged: tegra k1, tegra, nvidia, nexus 9, Nexus, google, Denver

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!

nexus9-1.jpg

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.

nexus9-3.jpg

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. 

nexus9-2.jpg

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.

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.

21.jpg

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.

IMG_0417.JPG

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.

One year later and the Nvidia Shield becomes a Tablet

Subject: General Tech | July 22, 2014 - 01:58 PM |
Tagged: twitch, tegra k1, tegra, shield tablet, shield controller, shield, nvidia, grid, gamestream

Shame on you if you skipped Ryan's review of the new Shield, for those that have and are looking for a second opinion you can check out The Tech Report and other links below the fold.  To quickly recap the controller is now optional but you can connect up to 4 simultaneously for group gaming, the built in 8" IPS display is capable of 1920x1200 and you can output video to an external monitor at 1080p.  The 192 shader processors on the Tegra K1 SoC inside should have no problems with fast paced action at these resolutions and at launch there are almost a dozen games optimized for the K1.  The focus on gaming performance is obvious but the inclusion of DirectStylus 2 for those who want to use the tablet for creating art adds an interesting extra feature to this tablet, especially if it will work with NVIDIA's ShadowPlay streaming technology as live broadcasts of artists drawing has become quite popular in some crowds.  It will be very interesting to see this tablet compete against consoles and the soon to arrive Steamboxes.

"Just under a year since the release of the Shield Portable, Nvidia has announced a second member of the Shield family. As expected, it's the Shield Tablet, an Android slate with an emphasis on gaming. Like the Shield Portable before it, the Shield Tablet will sell direct from Nvidia, not from a partner company. The Shield Tablet extends Nvidia's Android gaming focus to a new form factor, making it one of the first tablets anywhere with a fairly pure gaming mission."
