NVIDIA's 310.90 Driver - more performance, less vulnerabilities

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 - 08:46 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 - 08:18 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

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."

CES 2013: Tegra 4, the Vision of Windows RT?

Subject: General Tech, Graphics Cards, Mobile, Shows and Expos | January 7, 2013 - 09:42 AM |
Tagged: CES, ces 2013, nvidia, windows rt

It is the day after the NVIDIA keynote and the Tegra 4 floodgates are open. Sure, the rumors were fairly accurate, but I guess speculation waits for a solid basis to be believable.

The Tegra 4 marries 72 of the expected GPU cores with four… “plus one” as the bonus core is present although 4+1 branding does not seem to be… ARM Cortex-A15 cores. This push to an A15-based design provides a significant performance increase over Tegra 3. Another interesting feature is the ability to transmit 4K video should you have a suitable source or the rendered application can support 4K at a suitable framerate. You can then add in Icera’s LTE modem which is interesting in its own right to see a compelling product.

Jen-Hsun spent about as much time justifying the need for speed as he did hyping its performance. Photographers, particularly those who wish to dabble with HDR, are able to use the Tegra 4 to vastly increase the speed of image processing at the time of taking the shot. Tonal mapping for an HDR image will take just 200ms of processing which allows HDR to be used along with burst mode and a flash.

Paul Thurrott over at the Supersite for Windows ponders whether this was Microsoft’s vision for Windows RT. He wonders whether Microsoft will try to take a mulligan on the first generation similar to Windows Phone 7-based devices led us to Windows Phone 8. At the same point, the weight which the Surface was designed to bare is pretty immense if it was just designed to buckle to Tegra 4. I would not put it past Microsoft although the Surface does not strike me as a product designed to have a doughy half-baked middle -- despite what actually shipped.

PC World also notes how Qualcomm continues to improve their products and have just recently transitioned to a 28nm process for the Snapdragon S4. Qualcomm is a giant and even then there is also Samsung to contend with in the ARM space -- then you consider x86 brings at least Intel to the game with its massive advantage in legacy software that are usually not abstracted by a platform-independent runtime layer.

CES 2013: NVIDIA Officially Releases Tegra 4 SoC

Subject: General Tech | January 7, 2013 - 12:01 AM |
Tagged: tegra 4, SoC, nvidia, cortex a15, ces 2013, CES, arm

Details about NVIDIA’s latest system on a chip (SoC) for mobile devices leaked last month. On Sunday, NVIDIA officially released its Tegra 4 chip, and talked up more details on the new silicon.

Interestingly, the leaked information from the slide held true over the weekend when NVIDIA officially unveiled it during a press conference. The new chip is manufactured on a 28nm, low power, high-k metal gate process.  It features four ARM Cortex-A15 CPU cores running at up to 1.9GHz, one (additional) low power Cortex-A15 companion core, a NVIDIA GeForce GPU with 72 cores (not unified shader design unfortunately). In addition, the Tegra 4 SoC includes the company’s i500 programmable soft modem, and a number of fixed function hardware used for audio and image processing.

According to Anandtech, the majority of GPU cores in the Tegra 4 are 20-bit pixel shaders though exact specifications on the GPU are still unknown. Further, the i500 modem currectly supports LTE UE Category 3 on the WCDMA band with an LTE 4 modem expected in the future.

Tegra 4 will support dual channel LP-DDR3 memory, USB 3.0, and a technology that NVIDIA is calling its Computational Photography Architecture that allegedly will allow real-time HDR imagery with still and video shoots.

According to NVIDIA, Tegra 4 will be noticeably faster than its predecessors and the competing SoCs from Apple and Qualcomm et al. When compared to the Nexus 10 (Samsung Exynos 5 SoC) and the stock Android web browser, the Tegra 4 device (Chrome browser) opened pages in 27 seconds versus the Nexus 10’s 50 second benchmark time. Users will have to wait for retail devices with Tegra 4 hardware for independent benchmarks, however. Thanks to the higher top-end clockspeed and beefier GPU, you can expect Tegra 4 to be faster than Tegra 3, but until reviewers get their hands on Tegra 4-powered devices it is difficult to say just how much faster it is.

Speaking of hardware, the Tegra 4 chip will most likely be used in tablets (and not smartphones). Here’s hoping we see some prototype Tegra 4 devices or product announcements later this week at CES.

CES 2013: NVIDIA Grid to Fight Gaikai and OnLive?

Subject: Editorial, General Tech, Graphics Cards, Systems, Mobile, Shows and Expos | January 6, 2013 - 10:07 PM |
Tagged: CES, ces 2013, nvidia

The second act of the NVIDIA keynote speech re-announced their Grid cloud-based gaming product first mentioned back in May during GTC. You have probably heard of its competitors, Gaikai and OnLive. The mission of these services is to have all of the gaming computation done in a server somewhere and allow the gamer to log in and just play.

phpzXHEk9IMG_8955.JPG

The NVIDIA Grid is their product top-to-bottom. Even the interface was created by NVIDIA and, as they laud, rendered server-side using the Grid. It was demonstrated to stream to an LG smart TV directly or Android tablets. A rack will contain 20 servers with 240 GPUs with a total of 200 Teraflops of computational power. Each server will initially be able to support 24 players, which is interesting, given the last year of NVIDIA announcements.

Last year, during the GK110 announcement, Kepler was announced to support hundreds of clients to access a single server for professional applications. It seems only natural that Grid would benefit from that advancement: but it apparently does not. With a limit of 24 players per box, equating to a maximum of two players per GPU, it seems odd that a limit would be in place. The benefit of stacking multiple players per GPU is that you can achieve better-than-linear scaling in the long-tail of games.

Then again, all they need to do is solve the scaling problem before they have a problem with scaling their service.
