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!!

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 - 12:42 PM |
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 - 03:01 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 7, 2013 - 01:07 AM |
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.

NVIDIA GeForce GTX 660 SE Information Comes Out

Subject: Graphics Cards | January 4, 2013 - 09:10 PM |
Tagged: nvidia, kepler, gk106, gtx 660 se

Are you ready for another entry to the confusing graphics market?  NVIDIA has you covered with the upcoming GeForce GTX 660 SE that will target the $180-200 market and hit the AMD Radeon HD 7870 1GB square in the jaw.  With the current lineup of GeForce cards that is the one area where NVIDIA is at an obvious disadvantage with the gap between the GTX 650 Ti and the GTX 660. 

As is usually the case, when a new graphics card is ready to hit the market, leaks occur in all directions.  Already we are seeing screenshots of specifications and benchmarks from PCEVA.  If the rumors are right you'll see the GTX 660 SE released in Q1 of 2013 with 768 CUDA cores, 24 ROPs and a 192-bit memory bus.  Interestingly, the GTX 660 SE will be based on GK106 and has the same core count as the GTX 650 Ti...the performance differences will be seen going from the 128-bit memory bus to 192-bit.  

660se-2.jpg

Current GPU-Z screenshots are showing a clock speed of 928 MHz with a Boost clock of 1006 MHz, running just about the same clock rates as the GTX 650 Ti (though the 650 series does not have GPU Boost technology enabled).  It also looks like the GTX 660 SE will use GDDR5 memory running 5.6 GHz and a 2GB capacity

660se-1.jpg

With CES just around the corner (we are leaving in the morning!) we will ask around and see if anyone has more information about a solid price point and time frame for release!

A change is coming in 2013

If the new year will bring us anything, it looks like it might be the end of using "FPS" as the primary measuring tool for graphics performance on PCs.  A long, long time ago we started with simple "time demos" that recorded rendered frames in a game like Quake and then played them back as quickly as possible on a test system.  The lone result was given as time, in seconds, and was then converted to an average frame rate having known the total number of frames recorded to start with.

More recently we saw a transition to frame rates over time and the advent frame time graphs like the ones we have been using in our graphics reviews on PC Perspective. This expanded the amount of data required to get an accurate picture of graphics and gaming performance but it was indeed more accurate, giving us a more clear image of how GPUs (and CPUs and systems for that matter) performed in games.

And even though the idea of frame times have been around just a long, not many people were interested in getting into that detail level until this past year.  A frame time is the amount of time each frame takes to render, usually listed in milliseconds, and could range from 5ms to 50ms depending on performance.  For a reference, 120 FPS equates to an average of 8.3ms, 60 FPS is 16.6ms and 30 FPS is 33.3ms.  But rather than average those out by each second of time, what if you looked at each frame individually?

Video Loading...

Scott over at Tech Report started doing that this past year and found some interesting results.  I encourage all of our readers to follow up on what he has been doing as I think you'll find it incredibly educational and interesting. 

Through emails and tweets many PC Perspective readers have been asking for our take on it, why we weren't testing graphics cards in the same fashion yet, etc.  I've stayed quiet about it simply because we were working on quite a few different angles on our side and I wasn't ready to share results.  I am still not ready to share the glut of our information yet but I am ready to start the discussion and I hope our community find its compelling and offers some feedback.

At the heart of our unique GPU testing method is this card, a high-end dual-link DVI capture card capable of handling 2560x1600 resolutions at 60 Hz.  Essentially this card will act as a monitor to our GPU test bed and allow us to capture the actual display output that reaches the gamer's eyes.  This method is the best possible way to measure frame rates, frame times, stutter, runts, smoothness, and any other graphics-related metrics.

Using that recorded footage, sometimes reaching 400 MB/s of consistent writes at high resolutions, we can then analyze the frames one by one, though with the help of some additional software.  There are a lot of details that I am glossing over including the need for perfectly synced frame rates, having absolutely zero dropped frames in the recording, analyzing, etc, but trust me when I say we have been spending a lot of time on this.
