Intel's new six-core Westmere Xeon is as fast as the Nehalem before it, but even better at handling multiple processes at once. After proving itself in InfoWorld's threading benchmark tests and blade server shoot-out, Westmere arrived on my desktop this week in the form of the HP Z600 workstation. Thanks to this sizzling loaner from HP, I've already saved hours of video rendering time. If Adobe Premiere Pro made better use of Westmere's 24 logical CPUs (2 per core with Hyper-Threading enabled), I might not even have time for a cup of coffee.
Here at Interop's HotStage, where we put together the networks in advance of the conference, I pestered the HP guys to borrow a workstation because I was facing a huge backlog of video rendering. With Premeire Pro taking upward of three hours to render each video on my MacBook Pro (2.5GHz Core 2 Duo with 4GB of RAM), I was staring at impossible deadlines. Then HP whispered that I could borrow an as-yet-unreleased Z600 so long as I kept it under my hat until after the announcement. To sweeten the deal, HP also loaned me a couple of its 24-inch LP2475W widescreen monitors.

The Z600 is a no-nonsense black monolith aimed at engineers and other creative types who might know how to put 12 CPU cores to use. With Hyper-Threading turned on, the Windows 7 performance monitor shows the appearance of 24 CPUs, but alas Adobe Premiere Pro (like many other applications) is lagging behind the hardware curve. During the rendering process, Task Manager shows that Premiere Pro is using only half of the 24 threads (see screen image below). Aside from splitting such hairs, that same three-hour rendering job on the MacBook Pro plummeted to less than 20 minutes on the Z600 -- and that was with both Adobe Premiere Pro and Adobe After Effects running alongside the rendering engine.
