Evesham Voyager C720 Preview

So finally, let’s see how the machine performs. Unfortunately we didn’t have time to run a full suite of non-3D tests or battery life scores, so those will have to wait for a follow up review with a finished unit. Rather than testing at the screens native resolution we tested by outputting to a monitor using the DVI connection in order to make comparison easier. It made sense to compare the results to our previous champion the Dell Inspiron XPS. However, when we tested that notebook our maximum anisotropic filtering test was only at a level of 4x, and since then, we have upped it to 8x. However, this only goes to make the scores from the Evesham that bit more impressive.

The headline figure to start with is the 3DMark 05 score at 1,024 x 768, up from 4,898 on the Dell to 6,746. To put it into more perspective, a single desktop 7800 GT from out standard test bed system scores 6,869. For a mobile part that’s not bad going and makes this machine an awful lost faster than most of the desktop PCs on the planet.

With this kind of power, Far Cry, without HDR, hit 54.4fps at 1,600 x 1,200 4x FSAA and 8x AF. At the same setting, Half-Life 2 is more than comfortable at 76.9fps and Doom 3 at 48.6fps or 86.1 if you go without anti-aliasing. What this means is that you can look forward to playing next generation games, at native screen resolution, with features such as HDR turned on, and still get decent frame rates.

I have to admit that I’ve never really understood the need to play games on a notebook but having experienced this machine in action I can certainly see the appeal and I’ve no doubt that this will be a big hit with the LAN party crowd or with anyone that wants top end power without the space hogging presence of a desktop.

It’s undoubtedly another powerful statement from nVidia, who really seem to be giving ATI a torrid time at the moment. While ATI is struggling to get its next gen desktop part out of the door, nVidia has confidently striding ahead with the mobile part of its class leading GPU that’s been out on the desktop since June.


Verdict

The GeForce Go 7800 GTX is very impressive, beating nVidia's own previous fastest mobile GPU by some margin giving it the fastest chip on both desktop and mobile platforms. And while it may not have the styling to match Dell’s XPS for cutting edge technology at an affordable price, the Voyager C720 hits the spot.
