Radeon HD5570 Final Thoughts

Most everyone who reads this site is familiar with the concept of diminishing returns. As you get closer to the highest level of performance (let's call that 100 %...), it costs considerably more to get the last 10% of performance than it does to go from 80% to 90%. When you look at two gaming-class video cards using the same technology, the increase in frames-per-second doesn't match the increase in price. The HD5850 and the HD5870 are a good example; does the 33% increase in price give you a 33% increase in performance? You wish.....which is why lots more people are buying the HD5850.

Just as the law of diminishing returns works on the high end of the market, there is a corresponding force at work on the lower end of the scale. As you move closer to the lowest possible cost, you start to bounce up against fixed costs that won't budge. Marketing, sales, design, testing, certification processes, transportation, packaging, and connector costs are all stubbornly rigid. Right now, the cheapest cards at Newegg, based on NVIDIA and ATI chips are the 8400GS and HD4350, priced at $30 and $36, respectively. I dare say, we're not going to see any new cards introduced that will be any cheaper than these are; it's just not fiscally possible, if we assume that the vendor is going to make a profit. The vendor can try and cut every possible feature, performance enhancing hardware, included software, industrial design, packaging costs, etc. and end up with a product that barely functions, and it would still probably cost $25 on the retailer's shelf.

In my review of the HD5670, I wondered out loud, "How many more times ATI can slice the pie and still come up with a fully functional video card? Could there be one more cut, for an ultra-low power solution?" As it turns out, the Radeon HD5450 is that fully functional low-power card, and the Redwood class of ATI GPUs is still the lowest you can go and still support modern games. The game just changed with the introduction of a low profile card based on a down-clocked HD5670 GPU. This card eats HDTV for breakfast, has tons of headroom left over for whatever HW acceleration scheme comes along next, and can effectively run any new gaming title, albeit at lower resolutions and/or low-to-medium quality settings.


Even the best Integrated Graphics Processor (IGP) is still less than 25% as powerful as the Radeon HD5570, and they generally max out with 128MB of SidePort GDDR3 memory. Many of them struggle to render full HD 1080P video smoothly, and the CPUs that they are bundled with usually can't help the effort much. Needless to say, they can't perform even light weight gaming tasks. So, grab that old microATX board out of the closet, dust it off, add the Radeon HD5570, drop it into a shiny new, slim line HTPC box and you're off to the movies and gaming in style.
