Ryan and the crew have tested out NVIDIA's GRID, the cloud streaming service that lets you play games at 720p, as long as you have a 10 Mbps down connection on a network with a NVIDIA GameStream-ready 5 GHz Wi-Fi router and 60 ms or less ping time to a GRID server.  In testing Ryan did notice lag but he still found them playable once he mentally adjusted to the delay.

Today NIVIDA announced an upgrade to the GRID service, 35 of the 50 games on the service can now stream at a full 1080p and 60fps including Batman: Arkham Origins, Devil May Cry 4 and Dirt 3 Complete Edition.  In order to properly enjoy the HD quality you will need a compatible router from the list linked to above and connection of at least a 30 Mbps down, with 50Mbps being recommended by NVIDIA for best results.

NVIDIA's reported revenue of $1.15 billion just missed the analysts predictions, they saw an increase of roughly 4% from Q1 2014 but an 8% drop compared to the last quarter of 2014 which saw the release of the GTX 970 and the usual spike in sales from the holidays.  However when you look at net income, there was a drop of 2.2% compared to a year ago.  GPU sales made up the bulk of the income and are doing well as that division increased sales by 14% from last year bring in revenue 4.7% higher than last year.  Mobile Tegra sales saw a similar increase of 4.3% but the same can not be said for their LTE division, the Icera LTE modem unit is now on the chopping block, to either be dissolved or sold off.  You can get more numbers from this story at The Register.

New GeForce Bundle: Witcher 3 and Batman: Arkham Knight

Tagged: The Witcher 3, nvidia, GTX 980, GTX 970, gtx, geforce, batman arkham knight

NVIDIA has announced a new game bundle for GeForce graphics cards starting now, and it’s a doozy: Purchase a qualifying GTX card and receive download codes for both Witcher 3: Wild Hunt and Batman: Arkham Knight!

batman-witcher-glp-header.png

Needless to say, both of these titles have been highly anticipated, and neither have been released just yet with Witcher 3: Wild Hunt due to be released on May 19, and Batman: Arkham Knight arriving on June 23. So which cards qualify? Amazon has a page specifically created for this new offer here, and depending on which card you select you’ll be eligible for either both upcoming games, or just Witcher 3. NVIDIA has this chart on their promotion page for reference:

eligible_cards.png

So GeForce GTX 980 and GTX 970 cards will qualify for both games, and GTX 960 cards and the mobile GPUs qualify for Witcher 3 alone. Regardless of which game or card you may choose these PC versions of the new games will feature graphics that can’t be matched by consoles, and NVIDIA points out the advantages in their post:

"Both Batman and The Witcher raise the bar for graphical fidelity, rendering two very different open worlds with a level of detail we could only dream of last decade. And on PC, each is bolstered by NVIDIA GameWorks effects that increase fidelity, realism, and immersion. But to use those effects in conjunction with the many other available options, whilst retaining a high frame rate, it’s entirely possible that you’ll need an upgrade."

NVIDIA also posted this Witcher 3: Wild Hunt behind-the-scenes video:

In addition to the GameWorks effects present in Witcher 3, NVIDIA worked with developer Rocksteady on Batman: Arkham Knight “to create new visual effects exclusively for the game’s PC release.” The post elaborates:

"This is in addition to integrating the latest and greatest versions of our GPU-accelerated PhysX Destruction, PhysX Clothing and PhysX Turbulence technologies, which work in tandem to create immersive effects that react realistically to external forces. In previous Batman: Arkham games, these technologies created immersive fog and ice effects, realistic destructible scenery, and game-enhancing cloth effects that added to the atmosphere and spectacle. Expect to see similar effects in Arkham Knight, along with new features and effects that we'll be talking about in depth as we approach Arkham Knight’s June 23rd release."

Of note, mobile GPUs included in the promotion will only receive download codes if the seller of the notebook is participating in the "Two Times The Adventure" offer, so be sure to check that out when looking for a gaming laptop that qualifies!

The promotion is going on now and is available “for a limited time or while supplies last”.

NVIDIA gives Nouveau the boot again

Subject: General Tech | April 16, 2015 - 01:47 PM |
Tagged: nvidia, maxwell, Nouveau, open source

The initial benchmarks that Phoronix and other Linux tech sites ran on the new Maxwell cards from NVIDIA were using the proprietary binary drivers, the same as with all AMD cards.  Unlike AMD who have always released signed binary-only firmware blobs which could not be reverse engineered and modified for use, previous generations of NVIDIA cards did not require signed firmware images, only a lot of dev work.  Maxwell is locked down and the current open sourced Nouveau driver can now only be used to set up display outputs, it has no ability to use the card for hardware accelerated graphics.

NVIDIA states that the new requirement is to prevent shady characters from modifying slower cards to look like new Maxwell GPUs but Phoronix feels that they have gone overboard.  It is sad to see NVIDIA taking a step backwards in supporting the open source community, mimicking AMD's procedure of only offering binary-only firmware blobs though AMD is at least updating the blobs and open source driver relatively frequently.  That said, the new Maxwell cards do perform very well with the proprietary Linux driver so users should not feel they have to avoid NVIDA; unfortunately for developers the same is not true.

"While NVIDIA's new GeForce GTX 900 series is dominating for Linux gamers with excellent performance with their $1000+ GPU as well as great Linux OpenGL/OpenCL performance out of their lower-cost GPUs with excellent power efficiency, that's only when using the proprietary driver... NVIDIA's newer GTX 900 / Maxwell hardware is less open-source friendly than their previous generations of hardware. "

NVIDIA Released 350.12 WHQL and AMD Released 15.4 Beta for Grand Theft Auto V

Subject: Graphics Cards | April 14, 2015 - 01:27 AM |
Tagged: nvidia, amd, GTA5

Grand Theft Auto V launched today at around midnight GMT worldwide. This corresponded to 7PM EDT for those of us in North America. Well, add a little time for Steam to unlock the title and a bit longer for Rockstar to get enough servers online. One thing you did not need to wait for was new video card drivers. Both AMD and NVIDIA have day-one drivers that provide support.

You can get the NVIDIA drivers at their landing page

You can get the AMD drivers at their release notes

Personally, I ran the game for about a half hour on Windows 10 (Build 10049) with a GeForce GTX 670. Since these drivers are not for the pre-release operating system, I tried running it on 349.90 to see how it performed before upgrading. Surprisingly, it seems to be okay (apart from a tree that was flickering in and out of existence during a cut-scene). I would definitely update my drivers if they were available and supported, but I'm glad that it seems to be playable even on Windows 10.

The NVIDIA, Samsung and Qualcomm saga has been cleared to continue

Subject: General Tech | April 7, 2015 - 01:27 PM |
Tagged: nvidia, qualcomm, Samsung, patents, sueball

A judge has ruled that six of the seven patent disputes that NVIDIA has filed are valid and will proceed to court for judgment.  These patents involve the use of graphics coprocessors in mobile devices and have been judged to be worded in such a way that it does not matter if those GPUs are ARM, Imagination Technologies or Qualcomm.  This is not the end of the dispute, merely a pretrial to see if the claims are valid and worth going to trial.  Of course Qualcomm and Samsung dispute NVIDIA's claims and in Samsung's case they have already launched a counter suit claiming NVIDIA has violated six of their own patents.  You can read about the history of the latest legal battle in the tech world as well as today's judgment over at The Register.

Process Technology Overview

We have been very spoiled throughout the years.  We likely did not realize exactly how spoiled we were until it became very obvious that the rate of process technology advances hit a virtual brick wall.  Every 18 to 24 months we were treated to a new, faster, more efficient process node that was opened up to fabless semiconductor firms and we were treated to a new generation of products that would blow our hair back.  Now we have been in a virtual standstill when it comes to new process nodes from the pure-play foundries.

Few expected the 28 nm node to live nearly as long as it has.  Some of the first cracks in the façade actually came from Intel.  Their 22 nm Tri-Gate (FinFET) process took a little bit longer to get off the ground than expected.  We also noticed some interesting electrical features from the products developed on that process.  Intel skewed away from higher clockspeeds and focused on efficiency and architectural improvements rather than staying at generally acceptable TDPs and leapfrogging the competition by clockspeed alone.  Overclockers noticed that the newer parts did not reach the same clockspeed heights as previous products such as the 32 nm based Sandy Bridge processors.  Whether this decision was intentional from Intel or not is debatable, but my gut feeling here is that they responded to the technical limitations of their 22 nm process.  Yields and bins likely dictated the max clockspeeds attained on these new products.  So instead of vaulting over AMD’s products, they just slowly started walking away from them.

When 28 nm was released the plans on the books were to transition to 20 nm products based on planar transistors, thereby bypassing the added expense of developing FinFETs.  It was widely expected that FinFETs were not necessarily required to address the needs of the market.  Sadly, that did not turn out to be the case.  There are many other factors as to why 20 nm planar parts are not common, but the limitations of that particular process node has made it a relatively niche process node that is appropriate for smaller, low power ASICs (like the latest Apple SOCs).  The Apple A8 is rumored to be around 90 mm square, which is a far cry from the traditional midrange GPU that goes from 250 mm sq. to 400+ mm sq.

The essential difficulty of the 20 nm planar node appears to be a lack of power scaling to match the increased transistor density.  TSMC and others have successfully packed in more transistors into every square mm as compared to 28 nm, but the electrical characteristics did not scale proportionally well.  Yes, there are improvements there per transistor, but when designers pack in all those transistors into a large design, TDP and voltage issues start to arise.  As TDP increases, it takes more power to drive the processor, which then leads to more heat.  The GPU guys probably looked at this and figured out that while they can achieve a higher transistor density and a wider design, they will have to downclock the entire GPU to hit reasonable TDP levels.  When adding these concerns to yields and bins for the new process, the advantages of going to 20 nm would be slim to none at the end of the day.
