A programmer on the DragonFly BSD project is flying high as a kite this week after AMD admitted that a bug he discovered is an actual erratum the Sunnyvale chip maker was previously unaware existed in some processor families. Matthew Dillon, who had been tracking the bug for well over a year, finally came up with a test case in which AMD could replicate the error and confirm there's really a bug.
First unveiled a couple of weeks ago, Intel has officially added a new processor to its Atom line without a formal introduction. It's the Atom D2550, essentially a supercharged D2500 with a faster graphics core and Hyperthreading support, or you can view it as a slower-clocked D2700, which also features a faster graphics core than the D2500 and supports Hyperthreading. Let's break all three down.
After 
AMD fans might be looking forward to Piledriver, but the Sunnyvale chip maker isn't quite ready to move on from Bulldozer. On the contrary, AMD today sent out a message announcing two new FX-Series Bulldozer chips -- AMD FX-4170 and FX--6200 -- along with a price cut to its existing FX-8120 processor with eight processing cores clocked at 3.1GHz (4GHz via Turbo Core).
Conflicting 
We've never been so confused about a processor launch date as we are now. Actually, it's Intel that appears the most confuzzled over when exactly Ivy Bridge will make its official debut, as conflicting and incomplete reports continue to surface. The latest we're hearing is that Ivy Bridge is definitely being delayed until June, but let's back up a moment and see if we can make some sense of it all.
It's fair to say that Intel has conquered the desktop market and will probably remain on top for a long time to come, but it when it comes to mobile platforms like tablets and smartphones, ARM is the one with a stranglehold on the market. The Santa Clara chip maker has long said it plans to make a serious run at mobile devices, and starting soon, you'll see a bunch of smartphones sporting Intel inside.
Mobile World Congress is now in full swing, which means an added emphasis on mobile devices and related technology announcements. One of the more interesting to come out of MWC is Qualcomm's unveiling of its upcoming Snapdragon S4 Pro MSM8960 processor. The S4 Pro adds a bit of graphical kick with an Adreno 320 GPU baked in.
When it comes to mobile technology, the push to make things better, faster and smaller is non-stop and all consuming. The more functions you can cram onto a single chip, the better! Plenty of companies have thrown their proverbial hat into the convergence ring, but as the 800 lb. gorilla in the room, all eyes tend to gravitate towards Intel for trend-setting processor news. And who is Intel to disappoint? The company's already announced plans for a mobile SoC with built-in 4G, and it recently showed off new "Rosepoint" chips that combine Atom CPUs and Wi-Fi radios.
