Errata (a nice way to say to say "mistakes"). errata....

Errata indicate behavior that deviates from the published specs. The fact is all hardware devices contain errata of some kind. To compare Intel’s 105 known errata, with 32 planned fixes and 69 no fixes, we can also look at AMD’s errata from their aging AMD64 technology. Most errata require very specific conditions before they exist. People make more out of errata issues than they need to....

This guidance included shipping "hundreds of thousands of quad-core processors into the server and desktop market segments during Q4". Hardware error AMD has experienced a hardware errata in their current quad-core processors. Originally, AMD was reporting that only the 2.4 GHz part had the errata. The thing which makes this particular TLB and L3 errata damaging to AMD is that the fix significantly undercuts performance ; by up to 20% on average, and nearly 60% on at least one benchmark. In truth, with these continuing financial losses per quarter, a product that is not living up to very many of its expectations, and is clock speed limited, now with errata whose fix significantly decreases performance while, at the same time, forcing AMD to limit distribution until the hardware fix is made, I cannot imagine Hector Ruiz being the CEO of AMD for too much longer....

The device, originally scheduled to ship in October, could be delayed until December as engineers at Motorola's Semiconductor Product Sector in Austin, Texas, reportedly work to resolve "errata" that affect the new processor when run at speeds of 500 MHz or higher. Motorola's Technical Support Hotline has confirmed both the existence of the errata and its recommended workaround, which while preventing the problem, slows timing throughout the chip. The G4 processors in the Power Mac G4s that are now shipping also contain the errata, but their sub-500-MHz speeds keep them from encountering the corruption problem, sources said....

It is our understanding that these Phenoms still contain the errata (bug) which causes a decrease in performance by up to 20% when the BIOS fix/patch is applied, according to benchmark data provided by TechReport on December 6, 2007. The errata reportedly relates to the TLB (translation lookaside buffer, a type of high-speed "scratch pad" for keeping crucial internal data close to the core), as well as a portion of the L2 to L3 cache data exchange. AMD believes it is highly unlikely that the specific conditions which cause the errata to surface, which is, according to AMD, a condition which ultimately causes the CPU to shutdown following an unhandled Machine Check Exception....
