ATi Radeon HD 3450 Boston MA

Provided By:

The Radeon HD 3450 is a minor revision of the HD 2400 series, adding support for DirectX 10.1 and Shader Model 4.1, among other things.

With a relatively modest 40 stream processors, however, and a core clock of just 600MHz, it certainly won't run games such as Crysis smoothly, and you'll have to make do with painfully low resolutions and settings. Even Crysis' forgiving Low settings proved too much for it.

Although you can line up a pair in a CrossFire configuration, of more interest may be ATi's Hybrid CrossFire technology. If you buy an AMD motherboard with the new Radeon HD 3000 series integrated graphics, the HD 3450 can essentially link to it to combine the graphical power of the two. It isn't valid at this stage, but once compatible motherboards arrive you'll see system builders pushing these cards.

More interesting still is ATi PowerPlay, which shuts down parts of the card when not in use to keep power consumption to a minimum. The HD 3450 also supports the new DisplayPort interface, as well as HDMI, so it could be an excellent media card if graphics card manufacturers implement either - at this point only the latter looks likely.

This brings us to the 3450's real function, which is video. It supports ATi's Unified Video Decoder technology, allowing it to run full 1080p high-definition video without overstressing the CPU. Technically, it should be able to decode up to 1440p, but this is unlikely to be of use for some time - 1080p is the key and, crucially, the HD 3450 can manage it.

If you just want a cheap media-centre card for its video outputs and decoding capability, the GeForce 8400 GS is cheaper than this. But ATi's PowerPlay function may well be enough to persuade you it's worth spending that little bit extra, particularly if you can find one with HDMI.

Verdict

A great media-centre card with some nice features - and at an affordable price.
