Intel Pentium Extreme Edition dual-core CPU

Intel's fastest desktop - times two?

To get an idea of how good the PEE is at multi-tasking we started by playing Doom 3 on High Quality settings. As we expected, the ATI Radeon X850 handled it flawlessly. We quit the game and started a full system scan running in Norton AV which bumped CPU usage up to 75 per cent or so and then went back into Doom 3. Although it took a while longer to start up, gameplay was completely smooth and Norton's presence was completely undetectable. Once again, we quit Doom 3 and with Norton still running we set iTunes to transcode two albums' worth of MP3 files to AAC format. We opened Doom 3 up again, leaving Norton and iTunes running in the background, and the gameplay continued to be superb. It provided us with a computing experience that we have never had before. Very, very impressive, so just remember, the benchmarks don't give the full story.

Verdict

Intel Pentium Extreme Edition LogoWould we buy a brand new PEE-based machine? Probably not, but that's the answer we give with most new technology. We said it about Serial ATA, PCI Express, DDR memory and DDR2 memory, and now we're saying it about dual-core processors - ultimately, the price premium for the Extreme Edition will be too high.

That said, dual- and multi-core processors are definitely the way forward. Unlike Hyper-Threading, using a dual-core processor really is like adding a second CPU to your machine, rather than faking it up, as HT does. You really do have double the processor resources, all the time, not just when there happen to be some execution units going spare.

As is always the case, early adopters are going to pay a high price for small gains, but as Intel rolls out dual-core chips across all its platforms, software developers will be forced to code applications with multi-threading support. In the meantime though, anyone who's doing a significant amount of multi-tasking should see a significant performance boost right now.

How We Tested

After we had run SYSmark 2002 we used Windows Media Encoder 9 to encode a 416MB AVI movie file in WMV 9 format which finishes up 4MB in size. Next we used iTunes 4.7.1 to transcode a 22MB MP3 (128Kbps) audio file to AAC format at 128Kbps. Finally, we opened a 47.2MB TIFF in Adobe Photoshop CS 8 and resized it and increased the resolution so it grew to 658MB in size.
