AMD and Intel both need to improve their Linux support

Two different stories today focus on how both major CPU vendors have allowed their support for the new features present in their architectures to fall behind for Linux OSes.  From The Inquirer we hear about the how poor OpenCL support from AMD is leaving APU accelerated computing for Linux to lag behind Windows development.  This goes far beyond purely graphical tasks and the complaints we have heard from gamers as OpenCL is a computing language that can handle far more than just pushing pixels.  The two most common OpenCL applications that people are familiar with are the GPU clients for BOINC and Folding@Home, which enable you to chug work units on your graphics card or the graphics cores on your CPU.  AMD's Neal Robinson who is the current senior director of Consumer Developer Support has taken up the challenge of promoting Linux OpenCL support from within AMD, so keep your eyes peeled for news from his team.

Intel's Ivy Bridge is no better according to Phoronix, as testing shows very little improvement on the default Ubuntu Unity desktop with Compiz.  That is what allows Ubuntu users to show the iconic Desktop Cube on the Gnome desktop environment and using it shows negative effects on the general performance of the system.  Switching to KDE and OpenGL generally resulted in better performance as did Xfce.  Phoronix does not hold out much hope for the improvement of Compiz on Ivy Bridge processors or Intel's open source drivers for the near future, either for graphics or GPU accelerated computation.

"For AMD flaky Linux support isn't just a matter of gamers complaining, but now with its APUs, standard applications are simply not making use of the compute power that AMD needs to compete with Intel."

Due to popular request, I am going to try to keep our readers up to date on the current availability of graphics cards and pricing on the market.  With the recent price drops from AMD, the frequent out-of-stock status of the GTX 680 cards and the release of the GTX 670, I thought this would be a great summary of the current situation.

NVIDIA's highest end offering, the GTX 690

We will try to post new updates weekly or maybe more frequently as we see fit.  Newegg is our partner of choice for this today, so let's see what we have.

AMD Radeon HD 7000 Series

Radeon HD 7970 3GB - In Stock
Starting at $469

Radeon HD 7950 3GB - In Stock
Starting at $389

Radeon HD 7870 2GB - In Stock
Starting at $329

Radeon HD 7850 2GB - In Stock
Starting at $249

Radeon HD 7770 1GB - In Stock
Starting at $129

Radeon HD 7750 1GB - In Stock
Starting at $109

NVIDIA GeForce GTX 600 Series

GeForce GTX 690 4GB - No Stock
Starting at $999

GeForce GTX 680 2GB - No Stock
Starting at $499

GeForce GTX 670 2GB - In Stock
Starting at $399

In short, nearly two weeks later, nothing has changed.  For NVIDIA neither the GeForce GTX 690 can be found nor can the GTX 680 - a card that launched more than two full months ago.  To say we are disappointed in the capability for NVIDIA to keep up their end of the bargain would be an understatement and explains why we STILL have not used the GTX 680 card in our Hardware Leaderboard!!  The GTX 670 remains in stock though with four models available at Newegg including an overclocked MSI model for hte $399 MSRP.  Considering this might be our new favorite GPU, that is good news at least. 

AMD is still doing great on availability with the Radeon HD 7970 and HD 7950 widely available for the price of $469 / $389 with a set of three free games including DiRT Showdown and Dues Ex: Human Revolution.

XFX Throws into the Midrange Ring

Who is this XFX? This is a brand that I have not dealt with in a long time. In fact, the last time I had an XFX card was some five years ago, and it was in the form of the GeForce 8800 GTX XXX Edition. This was a pretty awesome card for the time, and it seemed to last forever in terms of performance and features in the new DX 10 world that was 2007/2008. This was a heavily overclocked card, and it would get really loud during gaming sessions. I can honestly say though that this particular card was troublefree and well built.

xfx_r7800_01.jpg

XFX has not always had a great reputation though, and the company has gone through some very interesting twists and turns over the years. XFX is a subsidiary of Pine Technologies. Initially XFX dealt strictly with NVIDIA based products, but a few years back when the graphics market became really tight, NVIDIA dropped several manufacturers and focused their attention on the bigger partners. Among the victims of this tightening were BFG Technologies and XFX. Unlike BFG, XFX was able to negotiate successfully with AMD to transition their product lineup to Radeon products. Since then XFX has been very aggressive in pursuing unique designs based on these AMD products. While previous generation designs did not step far from the reference products, this latest generation is a big step forward for XFX.

AMD will not chase Intel making "needlessly powerful" CPUs

Subject: Editorial, General Tech, Graphics Cards, Processors | May 19, 2012 - 01:52 PM |
Tagged: ultrabook, trinity, cloud computing, cloud, amd

Bloomberg Businessweek reports AMD CEO Rory Read claims that his company will produce chips which are suited for consumer needs and not to crunch larger and larger bundles of information. They also like eating Intel’s bacon -- the question: is it from a pig or a turkey?

Read believes there is “enough processing power on every laptop on the planet today”.

I disagree.

The argument revolves around the shift to the cloud, as usual. It is very alluring to shift focus from the instrument to the data itself. More enticing: discussing how the instruments change to suit that need; this is especially true if you develop instruments and yearn to shift anyway.

amd-new.png

Don’t question the bacon…

AMD has been trusting that their processors will be good enough and their products will differentiate in other ways such as with graphics capabilities which they claim will be more important for cloud services. AMD hopes that their newer laptops will steal some bacon from Intel and their ultrabook initiative.

The main problem with the cloud is that it is mostly something that people feel that they want rather than actually do. They believe they want their content controlled by a company for them until it becomes inaccessible temporarily or permanently. They believe they want their information accessible in online services but then freak out about the privacy implications of it.

The public appeal of the cloud is that it lets you feel as though you can focus on the content rather than the medium. The problem is that you do not have fewer distractions from your content -- just different ones -- and they rear their head once or twice in isolation of each other. You experience a privacy concern here and an incompatibility or licensing issue there. For some problems and for some people it makes more sense to control your own data. It will continue to be important to serve that market.

And if crunching ends up being necessary for the future it looks like Intel will be a little lonely at the top.

Get right to the gaming, AMD vs NVIDIA showdown

Ryan pitted the GTX670 and GTX570 against each other to show that in terms of gaming performance the GTX670 is a viable upgrade. [H]ard|OCP did something similar, testing the GTX670 and 680 against the HD7970 in a gaming performance showdown.  For those who are only interested in gaming performance they've assembled a great breakdown of four popular games at a variety of resolutions and both at stock clocks and the best OC they could manage.  The results are clear, for gamers it is NVIDIA with the clear win, with the GTX670 being a better value than the HD7970 and the GTX680 being a better performer.

"Wondering how the GeForce GTX 680 and GeForce GTX 670 compare to the Radeon HD 7970 and Radeon HD 7950 at stock frequencies as well as overclocked? You ask for it and we have done just that. Hold onto your hard earned cash and take note of just how the new GeForce GTX 670 compares with the rest of the competition."

The 2nd-Generation A-Series APU, codenamed “Trinity”, is a grounds-up improved design over the previous generation, enabling a best-in-class PC mobility, entertainment, and gaming experience. New features of the product design include:

  • Double the performance per watt of the previous generation;
  • The AMD HD Media Accelerator with a unique set of technologies designed to optimize video quality available with premium and Internet video content, and accelerate video file conversion;
  • An increase in CPU performance of up to 29 percent with higher processor speeds thanks to the next-generation AMD “Piledriver” CPU core with 3rd-Generation AMD Turbo Core technology, where power is dynamically shifted between the CPU and GPU depending on application needs, effectively providing a more responsive experience that can boost CPU frequencies to up to 3.2 GHz;
  • AMD Radeon HD 7000 Series graphics for an increase of graphics performance up to 56% over the previous generation. Combined, the CPU and GPU cores deliver more than 700 gigaflops of computing performance – several times more than the fastest x86 CPUs – to boost performance of hundreds of applications;
  • Up to 12 hours of battery life through CPU and GPU power enhancements, with clear battery life leadership in notebook form factors.

“The latest OEM notebooks, ultrathins, All-in-Ones and desktops based on the new AMD A-Series APU enable the best video and gaming experiences, highly responsive performance with AMD Turbo CORE, and accelerate an ever-increasing range of productivity and multimedia applications -- in sleek, stylish designs at price points that make sense,” said Chris Cloran, corporate vice president and General Manager, AMD Client Business Unit. “Our 2nd-Generation AMD A-Series APU is a major step forward in every performance and power dimension, allowing users to enjoy a stunning experience without having to give up the things that matter to them most. This experience doesn’t stop at mainstream notebooks. It carries over into affordable ultrathin form factors featuring the latest in AMD Radeon graphics.”

AMD A-Series APUs are also well-positioned to take advantage of the upcoming transition to the Windows 8 operating system.

“We are excited for the introduction of the 2nd-Generation AMD A-Series APU and are confident it will continue the great work Microsoft and AMD have done together on the A-Series APU,” said Aidan Marcuss, senior director, Windows Business Planning, Microsoft Corp. “We look forward to seeing the A-Series APU in action with Windows 8 to deliver a great user experience across a variety of hardware.”

For developers who want to engage in the industry’s move toward heterogeneous computing, the upcoming AMD Fusion12 Developer Summit will offer them a unique opportunity to enhance their knowledge base. More information on AFDS can be found here.

Unmatched Mobility
With more than 12 hours of ‘resting’ battery life, AMD is now an industry leader in notebook battery-life performance. The 2nd-Generation AMD A-Series APU delivers increased levels of performance, while consuming half the power as its predecessor.

These gains can be attributed to the new power-optimized “Piledriver” CPU core, as well as to AMD Start Now technology, which is designed to maximize system responsiveness by quickly entering and exiting low power states. With AMD Start Now, the computer resumes from sleep mode in as few as two seconds and boots to the desktop in as few as 10 seconds.

In ultrathin form factors, AMD enables an uncompromised visual experience thanks to a power-efficient and premium AMD Radeon graphics engine. Consumers can expect to see ultrathin notebooks based on dual-core 17-watt and quad-core 25-watt AMD A-Series APUs. These products will be easily identifiable by aluminum-styled VISION Technology stickers at a range of competitive price points.

Best-in-class Entertainment
As more and more people turn to their computers as the hub for their entertainment, the visual aspect of computing becomes ever more important. To enhance these capabilities, AMD created the AMD HD Media Accelerator – a unique set of technologies that enable the best video quality on a PC. Key features of the HD Media Accelerator include:

  • AMD Perfect Picture HD – An image, video processing and display technology that automatically makes images and video better with color vibrancy adjustments, edge enhancement, noise reduction and dynamic contrast fixes;
  • AMD Steady Video Technology – A technology that enables smooth playback of jittery video content with a single button click thanks to plug-ins for popular Web browsers and multimedia applications;
  • AMD Quick Stream Technology – A new technology that prioritizes video streaming on PC systems for a smooth, virtually uninterrupted video stream; True HD video chat with up to four people at once;
  • AMD Video Converter – A video compression engine for fast conversion and sharing of media files across multiple formats and devices; Full decode support for H.264, MPEG-2, VC-1, MVC, DivX and WMV.

Gaming Leadership
The 2nd-Generation AMD A-Series APU builds on AMD’s legacy of gaming leadership with an increase in graphics performance of up to 56% over the previous generation and support for:
AMD Eyefinity Technology – For the first time, this immersive technology is available from an APU without the need for a discrete graphics card Performance-leading DirectX 11 graphics architecture and 1080p gaming a life-like level of detail; AMD Radeon dual graphics support that delivers a performance boost of up to 75 percent when adding a discrete graphics card to the APU.11 The AMD Radeon dual graphics option also offers support for DirectX 9 for older game titles, and uses new AMD CrossFire Technology Profiles for easier updates.

Introduction, Overview



trinitydie.jpg

AMD’s position is not enviable. Though they’re the only large competitor to Intel in the market for x86 processors, the company is dwarfed by the Giant of Santa Clara. As a resident of Portland, I can’t forget this fact. Intel offices are strewn across the landscape of the western suburbs, most of them at least four times larger than any office I’ve worked at.

Despite the long odds, AMD is set in this course for now and has no choice but to soldier on. And so we have today’s reference platform, a laptop powered by AMD’s latest mobile processor, codenamed Trinity. These processors, like the older Llano models, will be sold as the AMD A-Series. This might lead you to think that it’s simply another minor update, but that’s not the case. 

Llano was released around the same time as Bulldozer, but it did not use Bulldozer cores. Instead it used yet another update of Stars, which is a mobile incarnation of Phenom II, which was of course an improvement upon the original Phenom. The “new” Llano APU in fact was equipped with some rather old processor cores. This showed in the performance of the mobile Llano products. They simply could not keep up with Sandy Bridge’s more modern cores.

Bulldozer isn’t coming to mobile with Trinity, either. Instead we’re receiving Piledriver. AMD has effectively skipped the first iteration of its new Bulldozer architecture and moved straight on to the second. Piledriver includes the third generation of AMD’s Turbo Core and promises “up to 29%” better processor performance than last year’s Llano-based A-Series.

That’s a significant improvement, should it turn out to be correct. Is it true, and will it be enough to catch up to Intel?

It is launch day for the GTX 670 and those seem to be pretty widely available for the time being.  As great a card as it is though, I am hesitant to think it will remain in stock through the end of the day based on past experiences with the GTX 600 cards.  Still, the GTX 680 is MIA and the few times I have seen it in stock it only lasts a couple of hours.  

AMD is still doing fine on availability with the Radeon HD 7970 and HD 7950 widely available for the price of $479 with a set of three free games including DiRT Showdown and Dues Ex: Human Revolution.
