f you've recently bought or built an Intel Sandy Bridge or AMD Fusion PC and found even their enhanced integrated graphics wanting, then you probably know you want a discrete video card. If you're seriously constrained by budget, or if you're not too keen on 3D games, the AMD Radeon HD 6450 provides one of the least-expensive ways to get basic discrete video: for only $59. But if you think there's even a chance you may need your card to do anything else, stop and think if you can scrounge up a few more pennies elsewhere before buying this card.

As befits its price, this card—the starting point for AMD's entire 6000-series lineup, the current-generation replacement for last year's ATI Radeon HD 5450—is lean in every way. It packs a mere 160 stream processors, 8 texture units, and 4 ROPs, along with an engine clock ranging in frequency from 625 to 750 MHz and a memory clock that can be tuned to 533–800 MHz if the card is loaded with DDR3 memory and 800–900 MHz if GDDR5 memory is installed.

AMD's reference version of the 6450 has three output ports: for VGA, for DisplayPort, and for DVI. As is the case with all of AMD's newer cards, the 6450 supports Microsoft's DirectX 11 (DX11) API for the most advanced visual effects, Eyefinity for easy multimonitor setups, and AMD APP for GPU-based compute acceleration.

Given the 6450's meager specs, the last is probably the only one you'll want to actually pursue. Though most consumers buy video cards with the intent of doing some kind of gaming, it can't be stated often enough that that's simply not the 6450's strong point. We ran through our usual suite of tests, and got almost exclusively unplayable results. Except for the routinely "easy" H.A.W.X. 2, in none of our games did the 6450 ever get even as high as 13 frames per second (fps) even at 1,024 by 768—and H.A.W.X. 2 just slipped in there with 38 fps (and, to be fair, an even 30 fps at 1,280 by 1,024).

Under what circumstances might you genuinely want a 6450? If you're building a small, simple system, such as a nettop or a home theater PC, or if power draw is a major concern, then this card will do the trick. It uses a maximum of 27 watts of power under load, and as little as 9 watts while idle; in our power tests, a system built with the 6450 used a mere 155 watts of power when under load.

If you don't want to limit yourself, you can drop several more dollars (about $5, as of this writing) on a 1GB ATI Radeon HD 5570. This card may be from the 5000 series, but it delivers markedly better frame rates across our spectrum of tests (20.4 fps versus 10.2 fps in Aliens vs. Predator at 1,024 by 768, for example; 55 fps and 44 fps in H.A.W.X. 2; 22.91 fps versus 12.98 in Just Cause 2 (also at 1,024 by 768); and so on. Or Nvidia's GeForce GT 430: It costs the same as the 6450, but turns in marginally better gaming performance, with sample scores of 1,869 in 3DMark 11 (versus the 6450's 1,213), 15.4 fps in Aliens vs. Predator (the 6450 did 10.2 fps), and 16.25 fps in Just Cause 2 (compared with 12.98). And though the 6450 did okay with H.A.W.X. 2, the GT 430 did better still—44 fps and 33 fps at 1,024 by 768 and 1,280 by 1,024 respectively.

The budget video card market has been a weird place for a while now, and has not been made more hospitable by the appearance of improved integrated graphics in Intel's Sandy Bridge and AMD's Fusion platforms. Even a bargain-basement discrete card will up the performance ante of machines based on these, so the AMD Radeon HD 6450 will suffice. But for most ordinary, everyday uses, either AMD's own 5570 or Nvidia's GT 430 will be a superior choice to the 6450—and not cost noticeably more.
