New Intel Core i7 processor makes 64 bit computing a reality! We knew this day would come. We've been waiting for more then two years to break free from our 32-bit shackles and finally embrace the 64-bit future. We have seen the future, and we have built a machine to take full advantage of it. Videoguys DIY7 is simply the most cost effective platform for video editing we've ever put together. For around $2,000 this machine blows the doors off any DIY build article we've ever done. The jump in performance and power from DIY6 to DIY7 is nothing short of amazing! To understand why this machine represents such a huge leap in NLE performance, we first have to understand the underlying technology under the hood. That would be Intel's Core i7 processor and X58 reference motherboard design.
That's right, the 920 processor used in our DIY7 machine gives you 8 cores of processing power, just like a dual Xeon HP workstation or Mac Pro. How could this be possible? Easy, sometimes you have to go back to the future. In this case it's an old technology called Hyper-Threading. What is Hyper-Threading? It's when the processor splits itself into two virtual processors in order to share the workload it's being asked to run. In its first incarnation, going back to P4 processor, Hyper-Threading was hit and miss. Under Windows 2000 Intel actually recommended shutting down Hyper-Threading as it caused instability. Videoguys also recommended turning off Hyper-Threading with certain NLEs and video capture cards. While the concept was great, the execution wasn't there yet. Mainly because most software and operating systems were not optimized for more then one processor, so while they were Hyper-Threading aware, the cost in stability often outweighed any performance gains. All it took was one finicky application or device driver and Hyper-Threading became more trouble then it was worth.
The i7 also includes a new SSE4.2 instruction set that enhances SSE by speeding up media trans-coding and 3D graphics. For video editors that means even faster rendering and encoding times. SWEET!
X58 Motherboards – taking the i7 to the next level Anyone who has been following the DIY Articles on the Videoguys website knows that we feel it is the chipset and motherboard, not the CPU that ultimately determines the stability and performance of your NLE machine. Pick the wrong chipset and you may find yourself frustrated by a finicky system that crashes far too often. The new X58 chipset by Intel does far more then just support the new i7 processors; it introduced some new technology that allows it to soar, including triple-channel RAM.
Tech Note: With triple channel memory it is important that you use 3 identical sticks of RAM at a time. Using pairs of memory will cause a performance hit. If you motherboard has 4 RAM slots, adding the 4th stick of RAM will also cause a performance hit. With i7 processors you want to go with 3/6/12/24 GB of RAM. The X58 chipset also includes something called Turbo Mode that allows for easier and safer over-clocking. We do not overclock our processors for our DIY articles, but we do overclock them later on when the machine migrates out of our demo room into someone's (this one will be mine) home video editing suite. If you plan on over-clocking the most important thing you need to do is provide adequate cooling and airflow. That's the main reason why we tend to put our DIY machines into gamer type cases. These tend to go a little overboard on the fans, airflow and cooling.
The motherboard actually ships with a mini operating system that allows you to launch a browser and access the web. This is very cool. Now you can download the latest drivers and patches for your hardware before you install the OS, eliminating some headaches. We did just that, downloading the latest Vista 64 drivers for our Quadro FX1700 card to a USB thumbdrive. Vista 64 – the secret sauce that makes it all happen You are reading it here first, Videoguys now recommends Windows Vista 64 for your non linear editing workstation. We have found that with service pack 1 it's running quite stable and you can shut down many, if not all, of the bloated features that drain the life of your systems performance. Vista 64 brings several advantages for video editing, the biggest and most important being memory usage. Windows 32-bit Operating Systems are only able to address 3GB of RAM. Actually the original amount of RAM that cam be addressed is only 2GB, but you can tweak the OS to use 3GB. What happens if you have 4GB or more? Basically it sits around unused. Some applications may be able to address and use some of that excess RAM, but in general, it sits wasted. With 64-bit operation systems you can address pretty much as much RAM as you motherboard can hold. With our Asus P6T motherboard that means six sticks of RAM. With 2GB sticks you get a whopping 12GB, use 4GB sticks and that's an insane 24GB of RAM! The other important part about Vista 64 is that our vendors are starting to add 64-bit optimization. This is no small matter and it has involved tons of engineering work with tons more to go - some of it requiring code to be completely re-written from the ground up. That explains why you are only seeing Vista 64 drivers and support, without XP64 support. It's simply too costly to go back and redo the old XP code. Engineering resources are limited, and companies have to go in the direction that will yield the best results. In this case it means focusing on Vista 64, even if that means upsetting some users of other operating systems.
Here are some very important guidelines:
Tech Note: While the Videoguys now recommends Vista 64, we do not recommend the 32-bit version of Vista for video editing. To run Vista right you need the extra RAM, and that is the primary benefit right now of Vista 64. If you can't go 64-bit, stick with good old reliable Windows XP Professional. Here is a quick list of Vista 64 optimizations that are a must for anyone running Vista 64 for video editing:

Graphics Card –GPU – Your mileage may vary We put a PNY Quadro FX 1700 card into our DIY7 machine. We feel this is the minimum card you want to use to run Avid Media Composer or Adobe After Effects. If you do a lot of compositing then the FX3700 is probably going to be a better call for you. We can also tell you that the nVidia GTX 260/280 and ATI Radeon 3800/4800 series of graphics cards are working well for many of our customers. We will be adding the NVIDIA Quadro CX graphics card with CUDA acceleration down the road. The additional encoding and Open GL acceleration this card delivers should take this system to another level. Potentially outperforming even Dual-Xeon workstations! Storage We decided to go with a 1TB system drive. Some folks would say this is overkill. Some tech experts recommend getting a very small boot drive, as a way to force you to keep the system lean. We don't recommend the skinny boot drive theory. While it's good for office computing and maybe gamers, it's not so good for video editing. You don't ever want to have a clogged up C: drive in your NLE workstation.
For our video drive we went back to our trusty G-tech G-SPEED eS from our DIY6 machine. We just installed a new G-Tech PCIe RAID card (It's actually a RocketRAID card) and the software provided by G-Tech in DIY7. We then plugged in the G-SPEED eS and did a cold reboot. The system recognized the G-SPEED eS and when we opened up Avid Media Composer, our projects and media were right were we left them. SWEET! DIY7 – This baby rocks!
We didn't run into any issues with the build. It actually went together far smoother then we expected. We didn't run into any driver problems, and so far everything is running great under Vista 64. For testing we've got DIY7 running our favorite NLE software suites including:
We are using HDV footage from my Canon HV20 for our testing. We hope to get our hands on some P2 and XD Cam HD footage for additional testing. We're also going to see how Adobe Premiere Pro CS4 handles AVCHD footage given all this computing power. We've been able to go from HDV to Blu-ray Disc and the results are simply spectacular. Not just the image quality, but the editing workflow itself. All this computing power makes editing even HDV footage manageable. With this system, we did notice that Avid Media Composer handles the HDV footage a bit better than Adobe Premiere Pro. Not just more layers, but the overall handling was superior in Avid. That is why I still see the need for the Matrox RT.X2 LE hardware with Premiere Pro CS4. I like being able to see my HD footage in all it's HD glory on our big 37" LCD HDTV. If you want to add several layers of HDV footage with 3d transitions and graphics the RT.X2 will give it to you in real-time, and that means you can be more creative and efficient. As I said earlier, Matrox has certified our DIY7 config for use with the RT.X2. Click here to read the full article with links to other articles that helped us make DIY7. |
