Loading ...There is a “waterfall” theory that has a well known application to car design but that is also misapplied to the PC industry. In the car world, features that first appear in high-end cars eventually become standard. You used to pay a significant amount for a CD player while now they are standard for most models; the high end cars have moved onto MP3 or satellite players.
Unfortunately, the same basic assumption about the “waterfall” effect has plagued the PC world.
For years, the conventional wisdom has been to load high-end features in the business PC, with everyday consumers eventually benefitting from those features when they became “commoditized”. You’ll recall the conversations along the lines of, “No one buys an Apple computer because you can’t run the same software on them that you run at work.” Other than for high-end gamers, the convention wisdom has been that consumers need only low- powered, low-end machines.
Clearly, the world has changed.
Video, music, pictures and other “blobs” (binary large objects) have changed the requirements for consumer PCs. Today everyday users expect superior graphics, powerful hard-drives, more memory and sometimes even faster processors than many business users. Running primarily Microsoft Office, Excel and Internet Explorer, on the other hand, has rendered business users the ones needing only lower-capability machines.
Yet, the typical business user’s workload requirement is in stark contrast to the amount that businesses generally pay for the machines their employees use. I am willing to bet that if you are reading this at work, the PC you are using costs as much as double the average PC in your local retailer ― and is likely significantly less powerful. IT departments tell you that they pay for other things like maintenance and warranties, software and support, all things you might not get on your store bought PC. And business PCs can sometimes be loaded with features that IT buys for insurance but are never used.
Many business users don’t like their work PCs because they are heavy and don’t compete with more compelling looking consumer PCs. You have to give Apple credit for a massive rethinking of PC industrial design. The PC is now a mainstream fashion and status statement (with some exceptions of course). Dell has colorful tops; HP offers sharp design.
But this is an evolving landscape. The expectations for and cost of retail PCs is going to change the way businesses think. At a Gartner conference last month I learned the name for this phenomenon: “consumerization”.
To quote a recent report from Gartner*: “The consumerization of IT focuses on how enterprises will be affected by and can take advantage of new technologies and models that originate and develop in the consumer space, rather than in the enterprise IT sector.”
Over the next few years we will likely see more and more effects from consumerization that will go beyond design to the software, networking and all other elements of our experience. Personally, I travel with an HP DV2 and would like to move to the new HP DM3. It’s great for work, and it plays music, video and other blobs.
I think I may have already been consumerized.

Speaking Directly

(12 votes, average: 4.00 out of 5)So the ATI Radeon HD 5800 Series is the first and only fully-compliant DirectX 11 graphics processor in the market. I get that. It is going to be ‘the thing’ that every game player worth their fragging-rights needs this holiday, if not before. I get that too. It is going to run the best and most exciting games ever with sexy stuff like tesselation. I even get that.
What I also get is – it’s about so much more than playing games.
The “more” is around something called DirectCompute. In many ways it’s the feature that my favorite applications are going to benefit from more than any other so I thought it would be worth spending a blog on.
DirectCompute is a component of the DirectX11 API to be released with Windows 7. It is fundamentally designed to enable GPU compute and enables applications to take advantage of the massively parallel computing power of the GPU.
What does DirectCompute mean for users? Simple: you have two great processors in your PC – one CPU and one GPU. And your system can use both to solve problems. For some workloads, like GPU-accelerated video transcoding and rendering, this combination can really speed up your throughput.
So as you begin compiling your holiday wish list, keep your eye out for systems with this astounding GPU compute capability. But here’s my caveat emptor. When you look at specifications of GPUs, it is important to note there are different levels of support provided for DirectCompute.
One level, which AMD terms DirectCompute 10, runs on the legacy path of the DirectX 11 API to support previous generation of DirectX 10/10.1 GPUs. If offered a system with this feature, just say no. You should demand what we at AMD call Direct Compute 11. This is the only version designed to unlock the full feature set of DirectX 11 and, as I mentioned previously, the only architecture that is fundamentally designed to enable GPU compute.
For developers, DirectCompute 11 represents a paradigm shift for GPU compute development. It will now be much more straightforward for developers to code using this architecture. No longer will they have to do contortions and jump through hoops to code what they want to. DirectCompute enables new algorithms that were not possible previously. Some examples of these advanced techniques are order independent transparency, ray tracing, better shadows, and depths of field. If you are interested in more details, you can read this white paper. DirectCompute is a de-facto industry standard for developers of GPU-compute applications and as such, it should not be confused with proprietary APIs (and by “proprietary” I mean supported by only one supplier’s hardware).
These are some of the reasons why at AMD, we are excited about the ATI Radeon™ HD 5800 Series graphics products. It’s not only the first and only GPUs in the market with full DirectX 11 support it is the only one to unlock the full feature set of Windows 7 and DirectCompute 11.We are proud of this technology leadership. We believe this industry standard will accelerate industry adoption of GPU compute applications running on Windows7 and add a new dimension to the end user’s computing experience.

What’s the Latest Thing the World Needs?

My guess is your answer isn’t: “another proprietary standard!” OK, I agree ― but please bear with me.
I remember the days of SNA. It ruled, it worked, it offered a huge jump forward and it got killed by the Internet, or more exactly TCP/IP. I remember the debate at IBM about the difference between “open”, “proprietary” and “de facto” standards. It seemed to make a big difference (at the time).
In those days, hardware or software specifications that were controlled by one company were what today we call “proprietary” standards. When a proprietary standard becomes widely used, it generally becomes a “de facto” standard even though it is not governed by a standards organization. “Open” standards, on the other hand, are typically developed by a standards organization or a consortium and are (with thanks to techweb), “available to the public for developing compliant products, open standards imply ‘open systems’; that an existing component in a system can be replaced with that of another vendor.”
So, to the point of this blog: graphics and Stream computing standards. There are many, but I’d like to compare one that is widely considered de facto, one that is currently proprietary but would like to become de facto, and one that is open.
Let us start with DirectX
Among other things DirectX is a Microsoft technology that gives the game player or video watcher accelerated graphics, video and sound performance within Windows. Today we are at DirectX 10.1 and heading to DirectX 11 later this year. DirectX and the similarly widely adopted Khronos Group’s OpenGL have generally replaced proprietary standards like Glide from the former 3dfx.
While you could argue that DirectX too started as a proprietary standard, mass adoption has made it a de facto industry standard – like it or not.
There is a need in the PC world for a programming model that allows both the CPU and the GPU to work together to excite applications. At AMD we call this Stream or Accelerated Computing. NVIDIA’s focus is on its proprietary standard CUDA, which competes with OpenCL ― which is the open standards-based approach, again governed by the Khronos group.
Recently at GDC, we demonstrated an OpenCL version of the Havok engine. And we expect to see more companies embracing OpenCL over time.
In the area of physics simulation, which is an example of Stream computing, NVIDIA links CUDA with its proprietary physics engine, PhysX, while AMD has chosen a different path in favor of open standards. OpenCL, which could also be described as a language and a set of APIs, ushers in a new era of computing by allowing applications to call on CPUs and GPUs in unified manner, resulting in the right processor accelerating the workload. And unlike the proprietary PhysX, OpenCL also allows many companies to develop and offer physics engines and other plug-ins of their own.
In an industry that loves a war, the new one to take note of may be between CUDA with PhysX against OpenCL and an army of numerous engines & plug-ins from independent companies.
In the end, the industry almost always comes to agreement on standards. In the PC industry we are currently driven by “de facto” standards, which generally come into use faster but can limit choice for users. When we all agree on “open” standards, on the other hand, we differentiate on a level playing field.
And history suggests that is really good for consumers.
The CUDA and OpenCL battle will be fought over the next few years, with applications and ― I suspect ― users as the battleground. In an ideal world we could all save time and money by agreeing on one or the other. Given that we believe in open standards, we vote for OpenCL.
Which do you vote for?
