ATI Radeon HD 4350 and 4550: Great HTPC Solutionsby Derek Wilson on September 30, 2008 12:45 AM EST

Oooh, new GPUs from AMD - however these ones aren't going to be breaking any performance records, they are both priced below $60.
The Radeon HD 4350 and 4550 are slotted in between integrated graphics and the set of hardware we took a look at recently in our Radeon 4670 review. The Radeon HD 4550 will run you around $45 - $55, while the Radeon HD 4350 will be priced at $39. Generally speaking, if you're a gamer you're not spending any less than $150 for a graphics card - so these GPUs are mostly for enabling hardware Blu-ray acceleration or providing a boost in performance over games running on integrated graphics.

While the Radeon HD 4670 was quite impressive with 320 stream processors, the same number that was in last year's Radeon HD 3870, the 4350 and 4550 only have 80 SPs. That's twice the number of SPs in AMD's 780G, the current highest performing IGP solution on the market. In our Radeon HD 4670 review we found that the GPU was fast enough for pretty much all current generation games at resolutions up to 1280 x 1024, but with only 1/4 the shader power of its $75 brother we don't have high gaming expectations from these cards.
Both the 4550 and 4350 are mated with a 64-bit memory interface and either a DDR2 or DDR3 frame buffer. With very little memory bandwidth, and very little processing power you need to have good expectations for these cards.
The competition from NVIDIA is a little blurrier; while the GeForce 9400 GT is priced more in line with where we expect these cards to end up, NVIDIA does have one trick up its sleeve. The GeForce 9500 GT, paired with 256MB of DDR2 memory (the same type you'd get on your desktop) is priced at around $65 - $70 but is currently available with a $15 - $20 mail in rebate, bringing it down to the about same pricepoint as the Radeon HD 4550.
