AMD Athlon 64 X2 6000+

Introduction and Specifications

AMD has been fairly quiet as of late. A few months ago, we took a look at their initial Quad-FX platform and FX-70 series offerings.  However, on the mainstream socket AM2 front, AMD hasn't made any real noise since the release of the Athlon 64 FX-62 way back in May of 2006. That's not to say AMD hasn't released any products since then. In fact, the company has launched a plethora of lower-clocked "Energy Efficient" processors for the platform and replaced the 125W Athlon 64 FX-62 with an 89W X2 5600+ at the same 2.8GHz and cache size. Frankly, enthusiasts waiting for a new flagship socket AM2 processor haven't had much to read about.  Thankfully, there is news from the AMD home-front today.

Today AMD is officially unveiling a new top-of-the-line socket AM2 processor, the Athlon 64 X2 6000+. The X2 6000+ sports a full 1MB of L2 cache per core and is clocked at a healthy 3.0GHz, just like the FX-74. Its cache configuration and clock speed should make the X2 6000+ the fastest desktop CPU to come out of AMD. So, what do you say we fire it up and see how it performs in comparison to the rest of today's high-end processor offerings?
