With the launch of the new AMD HD 7950 graphics card, a lot of information has come out from various sources. Bright Side of News reported a leaked document from one of AMD’s partners that listed the roadmap for the release of the rest of the HD7000 series graphics cards.

The slide itself is pretty self explanatory with the release schedule. After the HD 79xx series, the first thing we’ll see are the budget oriented, sub-$100 HD77xx cards in mid-February. Following that will be the mainstream, sub-$200 HD 78xx cards out in March, presumably along the same time as the Nvidia 600 series cards. So by the time Nvidia launches their new cards, AMD will have already released most of their line-up.

Of course, that’s not where the Graphics Core Next architecture release ends, as the dual-GPU HD 7990 comes out in early Q2 of this year, most likely in April.

Most of us go through so much electronic junk, buying more than we really need, and often just throwing it away. Sometimes a smartphone ends up in a drawer; sometimes it’s sold. Oftentimes a new computer is bought and the old one gathers dust in the garage. And I could say that I’m going to urge you to dig out that old computer and start using it again because I feel so strongly about protecting Mother Earth, but that’d be a lie. All I want to do, in fact, is to make you put your tech gear to better use and perhaps learn something in the process.

I’ll put this in the context of my recent experience with an old Mac. I’ve always wanted an iMac G4, the one with the half-dome base and a display that seems to float in the air. One day I found one on a website – something akin to eBay – called the seller up and the next day I was the proud owner of a once-powerful Mac. As it turns out, there’s much more power in my iPhone 4S than this Mac. It has an 800 Mhz processor, 1 GB RAM, and a 64 MB graphics card. Wow!

So besides looking very pretty on my desk, what was I supposed to do with this computer? Sure, I can browse the web with it, but it can’t run the latest browsers, so a lot of sites simply won’t work. Gaming is out of the question, as is any photo or video editing. It can’t keep up with video playback beyond some pathetically low resolution, and I’m pretty sure playing MP3s will be a stretch for the processor.

I could use it to write articles like this one with, so for that it’s still useful. But what I’ve decided to do is to get back to basics and really learn UNIX and the command line.

You know, “ls” for listing the contents of a directory, “ps” or “top” for checking what’s running, “rsync” for copying files to and from a server, “grep” to find things, and so on. I know some of this from having worked with computers for many years, but I still can’t say I’m very comfortable with a command line. The goal now is that my old Mac will, because it’s so old and slow, make me proficient at UNIX.

I’ve already started making a list of things I have to start working on. First on the list is learning some basics in the Bash shell, the Vim text editor, as well as how to do FTP and SSH. With that in place, I should be able to do a lot of the maintenance of my websites just by using the Terminal application on the iMac.

After that, I thought I’d venture on with network configuration, website hosting, and some software development. But that’s far away in the future so let’s not get too carried away.

Regardless of whether you want to use an old computer to become a command line whiz kid or not, there’s a lot of things you can use it for. It can be a file server, print server, used to download things with, and lots more.

Only your fantasy sets the limits, and your wallet will thank you, as well. Not a bad combination.

Often times AMD and Nvidia release their flagship GPUs with the launch of a new series of graphics card, but it’s the one under the newly crowned king that people most look forward to, the price/performance champion of the people. And in between all the festivities, we usually tend to overlook the middle sibling, the one who sits smack in the middle of the mid-range champion and the performance king. Today marks the launch of one such card, the AMD HD 7950.

The AMD HD 7950 is basically a cut down version of the HD 7970 released a month back. Clocked slightly lower than the 7970 and 256 lesser Stream units, the HD 7950 is made from the same wafer, with 384-bit bandwidth and 4.3 billion transistors and GCN architecture on a 28nm process. Our test units were all 3GB variants, although there will be 1.5GB HD 7950s coming out later, potentially costing $50 to $60 less than the 3GB versions.

Going by those specs and price, AMD has put the HD 7950 squarely against the current Nvidia champ, the GTX 580. And given that the 3GB price of the HD 7950 matches 1.5GB GTX 580s, expect a price drop very soon on the GTX 580.

So let’s take a look at our test cards today, both of which have custom cooling solutions and are factory overclocked to boot.
