Review: Alienware Suits Up With The MJ-12 8550i Workstation: Page 3 of 4

Do You Need All This Power?
So should you run out and buy this computer for your workplace? Well...maybe.

As with all multi-core systems, it depends on what software you're using to drive it. Running single-threaded programs on it is a lot like using a racing car to drive to the grocery store.

In general, most software built for the average desktop system today still doesn't fall into the multithreaded category. Even simple video rendering runs about as fast as it would on a Pentium D 945-powered computer because only one core is being utilized (Ulead VideoStudio and most video rendering applications written for current desktop PC platforms are single-threaded). As you make the rendering more complex (by, for example, changing video bit rates from the original) some small part of another core might become active. Continue to ramp-up the effects (overlays, titles, etc.) and you bring more of the computer's cores online.

It's when you move upstairs to more complex enterprise applications designed to run across multi-processor systems that you start to really use the MJ-12 8550i's potential: CAD/CAM software, database applications, and the like.

And, of course, there are games. When I ran Supreme Commander, an RTS game that takes advantage of multiple cores, the MJ-12 8550i did noticeably better than a single quad-core system with dual 8800 GTX cards in an SLI arrangement. (Of course, the MJ-12 8550i costs about $2,000 more than the competing system.)
