The Hydra chip
(Credit: LucidLogix Technologies)Last month, LucidLogix Technologies announced Hydra, a new take on multi-GPU implementation for desktops and notebooks. Monday, I got a chance to see a live demo of the technology, and get some clarity on what exactly this thing is expected to do.
Before we get into the demo, allow me to provide some context in case the previous link did not do its job (very likely, as looking back on it, it's kinda thin; anyway...). The Hydra 100 is a Silicon on Chip (SoC) solution to scaling 3D graphics. Basically, it allows you to, for example, insert up to four graphics cards from any one vendor (ATI or Nvidia) and receive linear performance from each card. That's the promise at least.
Now you may be asking, "Doesn't this already exist?" Well kinda. Each graphics card vendor has its own solution that allows you to place multiple GPUs into one system to achieve increased performance--ATI with Crossfire and Nvidia with SLI. What separates the Lucid method is the techniques involved in achieving this.

LucidLogix Technologies seeks to make your video card's processing more efficient. The Israel-based company claims that its new Hydra technology will direct graphic processing traffic between multiple GPUs, using several "intelligent parallelization algorithms." This is a system-on-a-chip solution that will be embedded into video cards and motherboards. LucidLogix claims this will result in the following:
1. "Cost-effective graphic performance with a near-linear to above-linear performance."
2. "Eliminate bottlenecks that exist in typical 3D graphic applications."
3. "Provide interoperability with all GPUs and chipsets."
4. "Work with the latest versions of DirectX and OpenGL."
The key things that stand out to me are the "above-linear performance" claim and the "all GPUs and chipsets" detail. The current video card in my PC is the ATI Radeon X1950. So, supposedly with Hydra I'll be able to add a Nvidia GeForce 8800 card to get better performance than the two cards are normally capable of. Whether or not the technology will actually work remains to be seen. LucidLogix claims this will improve the performance of any 3D application dynamically without developers having to write specific code. The trick here will be getting all of this to work seamlessly. I hope they can pull it off, as I'm in need of a "cheap" upgrade and I don't want to deal with any headaches. Hydra is set to be available starting in the first half of 2009.
Thanks to a new software driver Nvidia is cooking up, any PC game can be played in 3D, with no extra work on the part of game developers.
Beginning this summer, any PC with an Nvidia graphics processor will have the ability to run a game in normal mode, or in 3D, with the aid of 3D glasses.

The important part is that game developers won't have to do anything differently. They just continue to make their games the way they want, and Nvidia will take care of the rest. It's just an option for gamers though--it doesn't mean all games have to be three-dimensional.
The challenge for Nvidia is making the glasses widely available at retail, as well as turning the silly-looking lenses into something actually cool and "not as geeky-looking," said Drew Henry, general manager of the company's Media Communications Processor (MCP) group.
And yes, they promise the final product will be much cooler than the glasses pictured above.

CES 2008 may not have been a show for big wows, but there was plenty to talk about, at least on the computers and hardware front. For starters, Lenovo introduced three IdeaPads, the company's first consumer-oriented laptops for the U.S. market. (Lenovo also announced a corresponding line of desktops, predictably named IdeaCentre, for release in Europe, though we expect the line to reach our shores soon.)
HP caught our attention with the sub-$1,000, HD-equipped SlimLine desktop. Dell gave us a peek into the future with its 16-inch laptop prototype and the XPS 630 gaming desktop. Gateway launched its FX gaming brand into the mobile space with three new laptop configurations, while Alienware showed off its 15-inch gamer. We saw new ultraportables from Fujitsu and Asus, plus UMPCs from Toshiba and Samsung. We even got a glimpse at the tiny, Linux-based Everex Cloudbook. Desktops got smaller as well, if the Asus Nova P22 small-form-factor PC is any indication.
On the component front, Intel made a splash with the announcement of its first 45-nanometer notebook chips, known as Penryn; we shared our early test results for the new mobile CPUs and reported on plans for Penryn from Toshiba and HP. Intel also gave us a look at three high-end PCs that feature its components. Not to be left in Intel's wake, both ATI and Nvidia announced new graphics chips, the latter offering a peek at its Hybrid SLI technology.
Accessories that caught our eye included the Logitech diNovo Mini input device for home-theater PCs, the Ricavision Vave 100 Windows SideShow Universal Remote Control, and a Zyxel digital media adapter that lets you stream HD video and music from your PC to your home theater system.
This year's show also saw new storage devices, monitors, and security devices; click here to read all computers and hardware coverage from CES 2008.
Quake 4 image in Ray Tracing Demo
(Credit: Wired)For those who play PC games (and please count me in), the most expensive and necessary investment has always been the graphics card (also known as the GPU, graphics processing unit). High-end cards, from either ATI or nVidia, can cost $500 and up. That's not even factoring in the case, cooling system, power supply, etc., which also have to be equally high-end to support the increasingly large and power-hungry graphics cards. And there seems to be no end to all this. Or is there?
At IDF 2007, there was a demo running Quake 4. There wasn't much to talk about the demonstration itself (the game has been out for a while). As a matter of fact, there was no real game action on the screen--just a character walking around in a smooth 3D environment with excellent-looking lighting and shadow effects. What was impressive was the fact that the computer didn't have a graphics card in it, such as the Nvidia GeForce 8800 GTX, as one would have expected. Instead, the graphics were powered by an Intel multicore CPU that incorporates ray tracing display technology.
Unlike conventional GPUs that use raster graphics techniques to display graphics content, ray tracing models the behavior of light to create shadows and reflections for a more photorealistic presentation of 3D and 2D content. The concept of ray tracing is not new and rather simple: simulating the path that light rays take as they bounce around within the environment, while determining the color of each light ray that strikes the display before reaching the eyes. However, the sheer number of light rays needed to be traced requires a huge amount of computation. That is why this concept had to wait until now to come closer to reality (and indeed very close, judging by the demo), with multicore CPUs. It's predicted that in about three years, there will be computers that use processor-based ray tracing display technology. This means a gaming computer can have less components, be more energy efficient, quieter, and probably cheaper too.
As the ray tracing technique is completely different from the current raster technique, current games will not work with this technique and will need to be re-engineered (or ported) in order to take advantage of the new display platform. This is similar to how an Xbox 360 game will not run on a PS3 and vice versa. However, change takes time, and this is to be expected. And it's not like I am in a rush to discard my recent hefty investment in my SLI system. I will, though, try not to think about how many light rays there are that come out of my screen while flying over Outland.
