Another update

In our previous article and video, I introduced you to our upcoming testing methodology for evaluating graphics cards based not only frame rates but on frame smoothness and the efficiency of those frame rates.  I showed off some of the new hardware we are using for this process and detailed how direct capture of graphics card output allows us to find interesting frame and animation anomalies using some Photoshop still frames.

Today we are taking that a step further and looking at a couple of captured videos that demonstrate a "stutter" and walking you through, frame by frame, how we can detect, visualize and even start to measure them.

This video takes a couple of examples of stutter in games, DiRT 3 and Dishonored to be exact, and shows what they look like in real time, at 25% speed and then finally in a much more detailed frame-by-frame analysis.

Obviously this is just a couple instances of what a stutter is and there are often times less apparent in-game stutters that are even harder to see in video playback.  Not to worry - this capture method is capable of seeing those issues as well and we plan on diving into the "micro" level as well shortly.

We aren't going to start talking about whose card and what driver is being used yet and I know that there are still a lot of questions to be answered on this topic.  You will be hearing more quite soon from us and I thank you all for your comments, critiques and support.

Let me know below what you thought of this video and any questions that you might have. 

NVIDIA Employees Stole 100,000 Confidential Documents Claims AMD

Subject: General Tech, Graphics Cards | January 16, 2013 - 01:10 PM |
Tagged: stolen, nvidia, legal, Lawsuit, console, amd

Things might get interesting for a little while between AMD and NVIDIA again as a complaint has been filed by AMD accusing recently converted NVIDIA employee's of downloading and stealing 100,000 documents on the way out AMD's door. 

The company alleges that Robert Feldstein, Manoo Desai, and Nicolas Kociuk collectively downloaded over 100,000 files onto external hard drives in the six months before leaving the company. All three and another manager, Richard Hagen, were accused of recruiting AMD employees after leaving for Nvidia.

The most senior of these employees is Robert Feldstein who was acting as the VP of Strategic Development at AMD before leaving for NVIDIA and was responsible for getting AMD inside the Nintendo Wii U as well as the upcoming Xbox and Playstation consoles due out this year.  To say that "stealing" Feldstein was a big win for NVIDIA would seem like a bad pun now with the accusations on the table, but there, we said it. 

After looking at the former employees computers AMD found that "Desai and Kociuk conspired with each other to misappropriate AMD's confidential, proprietary, and/or trade secret information; and/or to intentionally access AMD's protected computers, without authorization and/or in a way that exceeded their authorized access."  And since Feldstein and Hagan were responsible for the recruitment of those former AMD employees, they were breaking the "no-solicitation of employees" agreement made before departure.

Obviously AMD hasn't come out with exactly what is in those 100,000 documents they accuse of being stolen, but the company is hoping that the US District Court in Massachusetts will help them recover the incriminating documents with a restraining order for all four current employees of NVIDIA forcing them to retain all current AMD-related documents. 

The unfortunate part of this for AMD is that if the document leak is true, the damage has likely already been done and they will have to sue for damages down the road.  NVIDA could be in for a world of hurt if the court finds that they were actively requesting those documents from the the four named in the complaint.

CES 2013: Intel Haswell HD Graphics Compared to GeForce GT 650M

Subject: Graphics Cards | January 12, 2013 - 12:02 PM |
Tagged: nvidia, Intel, hd graphics, haswell, geforce, dirt 3, ces 2013, CES, 650m

While wandering around the Intel booth we were offered a demo of the graphics performance of the upcoming Haswell processor, due out in the middle of 2013.  One of the big changes on this architecture will be another jump up in graphics performance, even more than we saw going from Sandy Bridge to Ivy Bridge. 

haswell1.jpg

On the left is the Intel Haswell system and on the right is a mobile system powered by the NVIDIA GeForce GT 650M.  For reference, that discrete GPU has 384 cores and a 128-bit memory bus so we aren't talking about flagship performance here.  Haswell GT3 graphics is rumored to have double the performance of the GT2 found in Ivy Bridge based on talks at IDF this past September. 

While I am not able to report the benchmark results, I can tell you what I "saw" in my viewing.  First, the Haswell graphics loaded the game up more slowly than the NVIDIA card.  That isn't a big deal really and could change with driver updates closer to launch, but it is was a lingering problem we have seen with Intel HD graphics over the years. 

haswell2.jpg

During the actual benchmark run, both looked great while running at 1080p and High quality presets.  I did notice during part of the loading of the level, the Haswell system seemed to "stutter" a bit and was a little less fluid in the animation.  I did NOT notice that during the actually benchmark gameplay though. 

I also inquired with Intel's graphics team about how dedicated they were to providing updated graphics drivers for HD graphics users.  They were defensive about their current output saying they have released quarterly drivers since the Sandy Bridge release but that perhaps they should be more vocal about it (I agree).  While I tried to get some kind of formal commitment from them going forward to monthly releases with game support added within X number of days, they weren't willing to do that quite yet. 

If AMD and NVIDIA discrete notebook (and low cost desktop) graphics divisions are to push an edge, game support and frequent updates are going to be the best place to start.  Still, seeing Intel continue to push forward on the path of improved processor graphics is great if they can follow through for gamers!

ASUS doubles down the RAM on their latest GTX 670

Subject: Graphics Cards | January 11, 2013 - 01:20 PM |
Tagged: nvidia, asus, GTX 670 DirectCU II 4GB

In addition to the custom cooler on the ASUS GTX 670 DirectCU II, there is also 4GB of RAM which is double the usual serving for a GTX 670 and should help its performance at high resolutions.  The core and RAM remain at stock speeds, [H]ard|OCP tweaked the GPU up 185MHz and the RAM by 175MHz so there is some room for overclockers to play with this card.  This time around [H] only tested single display performance and were disappointed with the performance when they compared it to the similarly priced HD 7970 but keep your eyes open as they will be testing SLI multi-monitor performance in the near future.

H_670_dcII.jpg

"Today we have an ASUS GeForce GTX 670 DC II 4GB video card up for review. Although there is no factory overclock, the video card supports 4GB of memory compared to the default 2GB. We will focus on single display performance in our revamped game lineup that includes Far Cry 3, Hitman: Absolution, and Sleeping Dogs."

NVIDIA to rip the ARMs off of Surface?

Subject: General Tech | January 10, 2013 - 03:20 PM |
Tagged: microsoft, surface, winRT, tegra 4, nvidia, arm

NVIDIA's new Shield gaming device might have distracted your attention from another new product they demonstrated which could be even more important to their success, a fully functional WinRT tablet.  The tablet is powered by a Tegra 4 chip and apparently runs smoothly even on this OS which was theoretically designed for ARM hardware.  DigiTimes feels that this is a sign that NVIDIA, who have had a long if somewhat troubled relationship with Microsoft, could become a chip supplier for new Surface devices and tablets.  Hopefully in the near future we will get to see a head to head review of two devices powered by different chips so that we can see which provides the best experience.

"Nvidia unveiled a pilot tablet based on its new Tegra 4 processor and Microsoft's Windows RT operating system at CES 2013, and since the device is already operating smoothly, Nvidia will have a chance of becoming the CPU supplier for next-generation Surface tablets or Windows RT-based tablets from other IT players, according to Digitimes Research senior analyst Eric Lin."

NVIDIA's 310.90 Driver - more performance, less vulnerabilities

Subject: General Tech | January 9, 2013 - 12:46 PM |
Tagged: nvidia, geforce, graphics drivers, fud

Say what you will about AMD's driver team but they don't tend to release drivers that allow some to elevate their privileges on their PCs.  That was unfortunately the Christmas present NVIDIA offered Windows users who installed 310.70, similar to the gift they offered Linux users last summer.  According to The Register, the new driver no longer contains that security hole, which makes upgrading to the newest driver more important than usual.  That is not the only reason to grab the new driver, NVIDIA reports that 310.90 provides 26% faster performance in Call of Duty: Black Ops 2 and up to 18% faster performance in Assassin’s Creed III as well as improvements to 400, 500 and 600 series cards in most other games.

"The vulnerability allows a remote attacker with a valid domain account to gain super-user access to any desktop or laptop running the vulnerable service," HD Moore, the developer of Metasploit and chief security officer at Rapid7, told SecurityWeek.

"This flaw also allows an attacker (or rogue user) with a low-privileged account to gain super-access to their own system, but the real risk to enterprises is the remote vector," he added."

CES 2013 Video: NVIDIA GRID Cloud Gaming Technology

Subject: Graphics Cards, Shows and Expos | January 9, 2013 - 11:46 AM |
Tagged: video, nvidia, grid, cloud gaming, ces 2013, CES

Despite all the excitement about the NVIDIA Shield handheld gaming device at CES, the company was also heavily promoting its GRID Cloud Gaming Technology, marking another company that is promosing "game everywhere on everything".  NVIDIA's claims of lower latency thanks to rendering and encoding on the same GPU have really yet to be verified as the hands-on demos they had at the show were running on local servers (not exactly a real-world test...).

NVIDIA isn't planning on releasing a self-branded service to the public but instead wants to sell servers to ISPs and service providers to increase density (more games per server) and performance.  There are no current cloud gaming companies using GRID technology so it looks like we'll have to wait a bit longer to see it's true capabilities.

CES 2013 Video: Intel Demonstrates Power Efficiency of Clovertrail, Tegra 3 and Krait

Subject: Mobile | January 9, 2013 - 11:18 AM |
Tagged: video, tegra 3, qualcomm, power, nvidia, krait, Intel, clovertrail, ces 2013, CES

One of the more interesting demonstrations from CES thus far has come from Intel in the form of power consumption comparisons between three of the current tablet SoC solutions.  Intel pits the Clovertrail SoC against NVIDIA's Tegra 3 and Qualcomm's Krait in a battle of power efficiency during video playback.  What you'll see is that Intel's test shows the Clovertrail processor able to not only run near but surpass the power efficiency of the ARM-based processors shown.

This is an incredibly powerful collection of tools that Intel has presented and we are hoping to be able to dive into a similar level of detail in the future.  By utilizing direct monitoring of power VRMs on the processor we could even see the power consumption of the CPU cores in comparison to the GPU cores and even against the L2 cache in some instances. 

Intel is on a mission to prove that they are not only competitive today in the tablet SoC market but that they are a leader in the market.  More to follow!!

Doing laps 'round Las Vegas

Tagged: CES, ces 2013, amd, nvidia, Intel, gigabyte

With so much to see at CES 2013 and with the vendors so far away from each other it is impossible to see it all in the limited time available, which is why it helps that there are other sites covering CES who might catch something Ryan and the boys didn't get to.  For instance The Tech Report had a chance to look at Gigabyte's new ultra thin GA-H77TN and GA-B75TN mini-ITX boards which will work in cases much thinner than a conventional board.  They also saw both AMD's upcoming roadmap and a tablet from Vizio using one of AMD's APUs while Intel showed off new Atoms and 7W Ivy Bridge CPUs.  They also weigh in on NVIDIA's new gaming box and the new Zbox.  Keep your eyes peeled on our front page as our coverage will be picking up as Las Vegas begins to come alive for another day of CES.

"The Consumer Electronics Show is off to a busy start, and we have staffers on the scene in Las Vegas and covering the show remotely. Before the show floor even opened, AMD, Intel, and Nvidia held major press conferences to reveal new products and discuss future plans. We have the goods on AMD's upcoming APUs, Intel's reference design for Haswell convertibles, Nvidia's Tegra 4 SoC, and other goodies from not only those companies, but also Gigabyte, Zotac, Lenovo, Vizio, and the USB 3.0 Promoter Group."
