Project Colossus
To meet our needs, The Colossus had to be a versatile powerhouse that could multitask like no other with an emphasis on CPU rendering, all within my budget. I decided to go with a dual-socket Intel e5500 platform, keeping the cost to performance ratio in mind to avoid diminishing returns. Data redundancy was a must and extra scavenged hard drives are used to help keep costs down. After putting a plan together, it was time to do some shopping.

Total Cost: $3,835.21

Drive Configuration
To get the most out of our hardware and prevent a performance bottleneck, our operating system main drive will use a solid state drive (SSD). Unlike mechanical hard disk drives (HDD) that use physical platters, SSDs use flash-memory based storage that gives them much faster read and write speeds and incredible random access times, albeit at a premium price–$3.00/GB compared to around $0.10/GB for HDDs. We’re using a 160 GB Intel x25-m G2, the latest iteration of Intel’s MLC flash memory SSDs.

The latest firmware update for x25-m G2 drives enables TRIM support in Windows 7, hopefully without bricking the drive, as the first firmware update did with an unfortunate few. Along with TRIM support for Windows 7, Intel has provided a toolbox suite to execute a manual TRIM operation in XP and Vistato retain optimal drive performance. This will, for the most part, help the drive avoid the inherent performance degradation in all SSDs that occurs over time.

Whenever data has significant value, it’s wise to back it up. We’re going to do just that on the fly with data redundancy using two RAID 1 arrays, where the data on each drive is mirrored to another in case of drive failure. Using three 1 TB HDDs in RAID 5 was considered, but the cost of an extra drive and more substantially, the cost of a decent RAID 5 controller made RAID 1 our best option. Our two arrays consisted of a 320GB array, used for personal documents, and a 1TB array using Western Digital RE3 enterprise grade drives, that will store project files accessed by editing, modeling and rendering software. I also wanted plenty of space to store non-vital data, such as movies and music. For that I used a lone 1 TB and 500 GB drives.

This configuration already presented a problem simply because many of the dual-socket Intel 5500 motherboards only have six SATA ports and once we add a SATA optical drive, it will need eight. To solve this, I used an inexpensive 1.5 GB/s PCI RAID controller with two SATA ports and one IDE port that will also give us backwards compatibility with older drives. Despite its limitations, it’s just what we need for storage drives that won’t require high-speed transfer or complex RAID setups.

Building The Colossus
The Supermicro X8DA3 is a large eATX board, sized to accommodate two e5500 series Xeon processors and up to 96GB of ECC Registered memory, you read that right, ninety-six gigabytes. Supermicro had a particularly small list of tested compatible memory for the X8DA3, so we made our best guess with what was easily available. 12GB of Patriot ECC Registered memory was initially used, but ended up being swapped out for 12GB of Wintec Industries ECC Registered RAM due to incompatibility issues.

Taking a look at the board, right away we can see that the location of the 1394 FireWire pinouts is problematic as they get covered by whatever is placed in the secondary PCI-E 16x slot. On the bottom right corner of the board there’s an SAS controller under the green heatsink and ports to support up to eight SCSI drives. Supermicro actually makes an identical board, the X8DAi, that omits the SAS controller. Because of a discount, they just happened to both cost the same at the time of our hardware purchase and who are we to pass up SAS support?

The Noctua NH-U12DX CPU heatsinks we’re using are server variants of the popular Noctua NH-U12P. They’re certainly overkill, but oh so quiet. To have access to the primary PCI-E 16x slot and the CPU1 8pin power slot, we’ve opted for an odd heatsink and fan placement where one fan pushes air through the heatsink and the other pulls air through, both bringing hot air towards the top of the case where it’s exhausted by the Cooler Master ATCS 840’s two massive 23cm fans. That brings up the topic of our choice of case.

A full tower was the only option short of a rackmount that will fit an eATX board. There’s a substantial difference in size between a mid-tower ATX case and the ACTS 840 full tower. This thing could eat a mid-tower and still have room left over. It’s beautifully clean aluminum exterior does away with the plethora of plastic vents, lights and other cheap aesthetics that seems to plague cases these days. Additionally, the ATCS 840 has a removable tray which made life easier when installing the RAM, processors and heatsinks, not to mention the clip-on heatsink fans.

The OCZ Z Series Gold 1000W was chosen for its high efficiency and modular cabling. For a 1 kW PSU, it’s surprisingly small and light. Because The Colossus will also be used as a render rig, it may be at a heavy load 24 hours a day for weeks at a time, that means an efficient PSU is crucial. With an 80 Plus Gold rating, the OCZ ZSeries Gold 1000W has been reported to run at 87% efficiency at low and peak loads and barely surpass 90% during optimal loading conditions. The power savings alone easily justify the higher cost and the modular cable system helped keep the case clean and was easier to work with.

The ATI HD5870
Certainly the most controversial piece of hardware in our rig is the video card, ATI’s new-to-market HD5870, the most powerful single GPU card available and is currently in short supply–which would explain why it’s retail price has raised from $379.99 to $429.99 since we bought it, making it the best hardware investment we ever made.

Remember that even though Project Colossus is all about building a high performance computer, as a workstation, it should be a stable work platform. Using a brand new piece of hardware (with brand new drivers) as critical as the video card is questionable, traditionally one would use a professional workstation card that’s designed specifically to work with simulation, modeling and rendering software. So, are we crazy or something? While The Colossus is a workstation, our goal was to build an all around power platform for both work and play. For the same price as the HD5870, we would have been able to afford something along the lines of a Quadro FX 1800, which should deliver gaming performance close to the midrange 9600GSO, another G94b GPU based card. All in all, a desktop card is a compromise, trading professional software performance for gaming performance. It’s still a new card with potentially unstable and/or incompatible drivers. We could have gone with a card in the HD4000 or GT200 series that would have had mature drivers. So, why the HD5870? Because we’re crazy.

Now that The Colossus put together, it’s time to test it and offer some juicy benchmark results. Stay tuned for Part 2, where we make your computer look puny.

Price Comparison:

For the prices, the totals were the cost shown after configuring the machine straight off Apple.com and Dell.com before taxes were calculated in. Both companies are offering free shipping which is a plus. Dell is offering the next generation Operating System, Windows 7, for free. Apple will charge just $9.95 for those who purchased a qualifying computer after June 8th, 2009 to upgrade Snow Leopard. Even with those details set aside, the Studio XPS 13 totals in $273 less than the same configuration for the MacBook Pro 13. Plus if you are willing to shell out more cash, there’s a lot more features Dell seems to offer with their model than Apple does. What are your thoughts on this?

Update: Since publication, we have updated a few elements of the chart and article. These changes include: Apple OS X Snow Leopard Price is $10, not $29 for purchases of MacBook Pros since June 8th, 2009. The screen resolution is WXGA for 16:10 aspect ratio, meaning a 1280×800 resolution, not 1366×768. The Studio XPS also has a multi-touch trackpad, similar to the MacBook Pro.

Realtime Technologies
The folks over at RTT are using Nvidia graphics technologies to create real-time raytracing models of prototype cars. Jen-Hsun invited Peter Stevenson, COO of RTT, on stage to show us a live demo of a new prototype Lamborghini model. The car apparently costs over a million dollars and only 20 will become available worldwide. Changes to the virtual model can be made in real-time and is intricate enough to detail every single internal component of the vehicle, not just the exterior looks. The high quality details of the interior leather, stitching, and materials was quite impressive. Nike, for example, was able to save a couple million dollars using Nvidia to create virtual prototypes of shoes.

Nurien Software (MMO)
Next, Nvidia’s CEO introduced Taehoon Kim, co-founder of Nurien, who introduced a new Massive Multi-player Online game which is going to be released soon. It was pretty much Sims, but on steroids. (Lots of Steroids.) The game could render people in real time, simulate life-like movements, and looks damn good. Another neat feature that they mentioned was the ability to choose real videos to be playing on TV screens or uploaded photos on photo frames in virtual homes, so other players who enter your area will be able to see all of your personalized content since every component of the game is networked.

SportsVision
If you watch Football or paid any attention to the 2008 Olympics, you probably have noticed a lot of virtual graphics being added to the arena. For example in the swimming events, a line is overlaid on the screen to show the time that the contestants would need to beat to reach a world record. The graphics was added without harming the view of the athletes and this was done using GPUs to calculate fluid movement around objects. NASCAR is using Sportsvision technology to display the effects of drafting.

Photosynth
A new product Microsoft just launched a couple of days ago allows stitching multiple photos together in a virtual environment. It automatically creates reference points from objects in images and can put them together, the more photos the better. Joshua Edwards from Microsoft Live Labs previewed some samples of the Stonehenge in the U.K. and the National Archive building in D.C. in impressive detail. The best part is that anyone can create these high quality 360 virtual views of an area with just a digital camera.

Perceptive Pixel
Jeff Han stepped on stage to demonstrate the next generation user interfaces. Perceptive Pixel has taken UI graphics to the next level. He used a whopping 100-inch multi-touch display to demonstrate some stuff you can’t do with a mouse. Although he expects first practical applications to be for the military and high-end design, he expects simpler versions to reach consumers soon. And it already has with touch screen devices such as the Apple iPhone.

The Ending
I started making my way back to the expo hall, but Tricia Helfer, an actress, who’s on Battlestar Galactica and Burn Notice, was speaking about how virtual characters play a role in television. Nvidia plays a huge roll to make much of the graphics we see in Hollywood films actually be rendered and put on the big screen. It was Nvidia’s and the CEO’s first time hosting such a large event. It went pretty well and looks like it was success so far. I’ll be on the show floor covering some of the new stuff that’s being shown off. So keep checking back for more Nvision 08 content over the next two days!

This September, about two and a half years after the launch of the PlayStation Portable in the United States, Sony will finally release an improved model. The new model, PSP-2000, is not the second generation of the PSP, but is rather an enhanced version of the current unit. One of the most useful features in the new model is the ability to output photos, movies, and games onto a television screen at standard definition resolution (480p) with a set of AV cables. Next, to solve the unit’s bulkiness, Sony slimmed down the PSP-2000 by about 20% and made it 30% lighter. Although the unit is still way bigger than a iPod Video or iPhone, it’s a good improvement.

On the technical side, the internal RAM has doubled from 32 to 64MB requiring less loading cycles. Although the new CPU requires less power and UMD reading time has been reduced, the battery life remains the same since a smaller battery had to be used to fit into the slimmer unit. Some rumors indicate a possible brighter LED backlit screen, which could drastically improve battery life, however no official statement has been issued. Also as a bonus the new PSP can now be charged using a USB cable, though it will take 5 hours instead of 2.5 with a AC adapter. The WiFi switch and speakers have been repositioned for easier access and the IR has been removed because it was never used. One thing we didn’t like was that the UMD now literally “falls” into a slanted tray instead of using the loading mechanism which used to take in and pop out the disk.

The PSP 2000 “core package” will retail at $169 and will include only the console (black), a battery, and an AC charger. (Original PSP cost at $250 at launch.) In addition a Ice Silver PSP bundled with Daxter, a 1GB card, and a UMD movie will be available for $199 on the same day (September 10th). Retailers such as Amazon are already taking pre-orders for the PSP-2000 at no extra cost. Also in the situation that Sony drops the price before or within 30 days after launch, Amazon will refund the price difference!

Pre-Order: PSP Slim for $169 (NO TAX + FREE Shipping)
