It is really hard to say exactly which is better because that would depend on exactly what you are using it for.
Example: #1 doesn't mention the video card or chip. These days lots of processing of images and video is done by the chip on video card and not by the main processor.
Example #2 It mentioned video in the line "Radeon™ HD 7480D Graphics" but that is a tiny chip built on the processor, not a dedicated card. Better than some, not awesome.
If I had to select I would take the second one (as long as it is Windows 7, which I prefer right now).
But, neither is a fast machine. I really suggest searching a bit more and finding a machine with an Intel processor. In same price range they just run better. See chart on this page:

That is a "gaming" review but remember that processing is processing. To run games, edit video and other things, you need four basics to be good. CPU, GPU, RAM and disks.
In March I purchased 2 machines based on the Intel i5-3570 and we like them. Both came with 8GB RAM, we boosted to 16GB. One was on sale at Micro Center (Power Spec House Brand) for only $575 but had average video so I got a decent add-on card for $100 more. The other I got from CyberPower but through Amazon.com sale (premade system) and it had good video card and was about $850
So, for under $1000 you can get better than what you listed. The AMD CPU is just not the thing these days (but AMD Radeon Video chips and cards are good)
