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: Vizio Creates Windows 8 Tablet with AMD CPU

Why not open up CES-proper discussion with a tablet announcement?

AMD has begun their push into the tablet space with Vizio being one of their first OEM partners to announce products at CES. Due to AMD being one of the select few to still maintain a proper x86 license, they are about your only option outside of Intel for a true Windows 8 tablet. Vizio took them up on that position.

The Vizio Tablet PC, seemingly a play on their original Android-based Vizio tablet with an added declaration that “I am a PC”, will run standard Windows 8 certified as Microsoft Signature. No bloatware will be included which should help users experience the performance that 60-day antivirus trials and auto-launched demo notifications absorb.

On the technical side, the Tablet PC is loaded with 2 GB of RAM, an 11.6” full 1080p display, and a 1.0 GHz AMD Z60 processor. 64 GB of solid state storage is included although Windows 8 has been known to stake claims to a large portion of that. Readers of our site would probably have a primary computing device although this might be worth watching as a secondary device. You do not have a whole lot of other options for Flash support or access to non-default browsers.

AMD Has Lots to DisplayPort at CES 2013

Subject: General Tech, Graphics Cards, Displays | January 3, 2013 - 07:32 PM |
Tagged: ces 2013, CES, DisplayPort, amd

It has been several months since we first heard about AMD’s multi-stream transport hub -- its friends call it MST hub -- announced with the FirePro W600 last June. Since then news has been pretty quiet about the 1-to-4 DisplayPort device.

It turns out that AMD wants to roll the dice in Vegas along with several other demonstrations.

The cute feature for the MST is its ability to split a 4K image into four 2K monitors. The reason why this is cute is because the hub enables the user to plug four-times as many monitors as they have DisplayPort 1.2 sockets on their GPU. The W600, for instance, contains 6 DisplayPort 1.2 plugs which enable it to drive 24 separate monitors from a single-slot card.

Unfortunately, another feature of DisplayPort 1.2 is the ability to route sound uniquely to each display. The hub, as announced in June, is incapable of providing audio from its one input to its four displays.

A last goodie is the capacity to mix landscape and portrait monitors together in an Eyefinity setup. Stay tuned for our impending CES 2013 coverage for more details on these demos.

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.

Meet Tahiti LE, the new 7870 MYST Edition

Tagged: powercolor, 7870 LE, MYST edition, tahiti LE, amd

The 7870 Limited Edition is a bit of an odd duck when you compare it to a stock 7870GHz Edition; it has 1536 stream processors as opposed to 1280 on the stock card, the base clock of 925MHz (975MHz Boost Clock) is slower than the 1GHz but the RAM is clocked even higher than a 7950 at 6GHz.  [H]ard|OCP wanted to see just how these tweaks effected the performance of the card, both at stock speeds and at their highest stable overclock of 1.2GHz GPU and 6.2GHz VRAM.  Check out the performance results to see if this card can approach the HD7950's power.

H_7870LE.jpg

"PowerColor has released a new graphics card based on the new AMD "Tahiti" 7870 LE core. We will investigate whether it is a worthy Limited Edition or simply a Lame Edition by comparing it to a Radeon HD 7870 GHz edition and a GTX 660 Ti with comparisons also to an HD 7950. Will this card be a deal, or a dud? You may be surprised."

The AMD Closed Loop System

Closed loop water cooling is not new, but it certainly is a pretty hot topic now.  Some of the first units out there had some interesting issues (like internal corrosion clogging everything up), but once those teething problems were solved the closed loop systems turned out to be pretty effective and easy to install.  Initially these units had the performance of a top end air cooler, but with a lot lower noise.  The latest generation of liquid cooling systems (LCS) is now further improved and provides performance approaching that of larger, more complex cooling systems.  These products will not replace exotic systems like phase change, but they provide a lot of cooling in a fairly decent sized package.

amd_lcs_01.jpg

Clean lines and graphics give this box a striking look without being tacky.

Last year with the introduction of the AMD FX-8150, AMD decided to create a SKU which not only included the CPU, but also a fairly robust LCS.   This unit is based on an Asetek design which features a double wide cooler/reservoir with the push-me/pull-ya fan combination.  Other manufacturers offer this particular product under a variety of names, but this is simply an AMD FX branded unit with some small cosmetic changes to differentiate it from other units.

AMD will eventually offer this cooler with the new Vishera based FX-8350 CPU (or at least we assume they will), and we wanted to take this combination out for a spin.  In our FX-8350 review we did not hit the overclocking targets that AMD had set.  In most literature that we were provided AMD stated that most FX-8350 parts would be able to hit around 5 GHz with some aggressive cooling.  In our review I was able to get to around 4.6 GHz max and around 4.5 GHz stable with better than average cooling.  The results were not as impressive as we had hoped, but we again did not have a top end cooling solution such as what AMD provides with this particular LCS.

With a brand new LCS in hand, I retested the FX-8350 to see how hard it could be pushed.  I also wanted to see how this particular unit performance in terms of thermal properties.  The results were quite surprising for me, as this is my first real experience with a LCS.

Phoronix on OpenCL Driver Optimization, NVIDIA vs. AMD

Tagged: opencl, nvidia, amd

The GPU is slowly becoming the parallel processing complement to your branching logic-adept CPU. Developers have been slow to adopt this new technology but that does not hinder the hardware manufacturers from putting on a kettle of tea for when guests arrive.

While the transition to GPGPU is slower than I am sure many would like, developers are rarely quick on the uptake of new technologies. The Xbox 360 was one of the first platforms where unified shaders became mandatory and early developers avoided them by offloading vertex code to the CPU. On that note: how much software still gets released without multicore support?

7-TuxGpu.png

Phoronix, practically the arbiter of all Linux news, decided to put several GPU drivers and their manufacturers to the test. AMD was up first and their results showed a pretty sizeable jump in performance at around October of this year through most of their tests. The article on NVIDIA arrived two days later and saw performance trended basically nowhere since February with the 295.20 release.

A key piece of information is that both benchmarks were performed with last generation GPUs: the GTX 460 on the NVIDIA side, with the 6950 holding AMD’s flag. You might note that 295.20 was the last tested driver to be released prior to the launch of Kepler.

These results seem to suggest that upon the launch of Kepler, NVIDIA did practically zero optimizations to their older "Fermi" architecture at least as far as these Linux OpenCL benchmarks are concerned. On the AMD side, it seems as though they are more willing to go back and advance the performance of their prior generation as they release new driver versions.

There are very few instances where AMD beats out NVIDIA in terms of driver support -- it is often a selling point for the jolly green giant -- but this appears to be a definite win for AMD.
