SoundBlaster X-Fi Elite Pro

Last year's Creative Audigy 4.0 Pro was a tad disappointing because it used much the same technology as its predecessor. But now, after having spent around $100m on developing the new X-Fi chip, Creative is back with a true next-generation audio card.

The X-Fi Elite Pro sits at the very top of Creative's new range and as such includes a number of extras. It has 64MB of onboard RAM for storing game sounds and, whereas the entry-level X-Fi cards have a signal-to-noise ratio of 109dB (decibels), this one boasts an astonishing 116dB. The biggest visible difference, however, is the break-out box, which is twice the size of the old Audigy desktop unit.

Unlike previous models, the Pro includes a pre-amp for hooking up a turntable to it, which is handy if you want to convert your old vinyl into MP3s. Unfortunately the FireWire port has been given the old heave-ho.

As with all top-of-the-range cards from Creative, musicians are well catered for with this offering. There are both coax and optical digital connectors on the break-out box, as well as a pair of full-sized midi ports. It's easy to hook guitars or microphones up to the card via the jack sockets, while the low-latency Asio drivers for use in applications such as Cubase make recording as painless as possible.

But even when used for day-to-day music listening and movie-watching, the X-Fi puts in a cracking performance. The new '24bit Crystalizer' mode is especially impressive for listening to MP3s. Through a process of up-sampling it restores some of the punch lost during the compression process - the results are startling. Music is meatier and crisper when the effect is turned on and, unlike competing systems, it makes it sound natural rather than processed, so your ears don't tire of the effect.

Creative's cards have always been a benchmark for gaming performance because they offload processing onto the card rather than using the PC's main CPU. This means faster frame rates in games. The X-Fi is no different in this respect. Our test using the Right Mark 3DSound benchmarking software showed a CPU utilisation of just 4.3 per cent on a 2GHz Pentium 4. However, that was only a marginal improvement on previous results from an Audigy 4.0 Pro. Also, in the patched X-Fi version of Doom III we used there wasn't really a noticeable improvement over the Audigy 4.0.

Games will need to be specially programmed to make the most of the X-Fi's abilities, and we expect greater things to come in the future.
