New and Noteworthy: Apple Delays 3Q Filing Due to Options; Meet the Xeon: Inside the Mac Pro's processor; more

Apple Delays 3Q Filing Due to Options ABC News reports that Apple said Friday it will delay filing its latest quarterly report and expects to make "significant changes" to results for the period because of irregularities related to past stock-option grants. "In a filing with the Securities and Exchange Commission on Friday, Apple said it expects to have to restate past results in order to take non-cash charges for compensation costs related to stock option granting practices."

Meet the Xeon: Inside the Mac Pro's processor Macworld does some G5/Xeon comparing in an article about the Mac Pro chip. "With the Xeon 5100, Intel claims that it has eliminated one huge performance advantage held by the PowerPC architecture: vector processing. Known to Mac users as AltiVec, or the Velocity Engine, this technology increased vector-based processing significantly on the PowerPC machines, and was one of the reasons that applications like Photoshop were able to manipulate such large image files with ease, even when other parts of the Mac subsystem weren't as fast as comparable Intel-based PCs."

Apple's Mac Pro: A Discussion of Specifications AnandTech has a stellar look at the Mac Pro's specs, noting some interesting features of the included Xeon processors, and attempting to clear up some of the confusion concerning FB-DIMMS. "During Steve Jobs' keynote, he put up a slide that listed the Mac Pro as having a 256-bit wide DDR2-667 memory controller with 21.3GB/s of memory bandwidth. Unfortunately, that claim isn't being totally honest with you as the 256-bit wide interface does not exist between the memory controller and the FB-DIMMs. The memory controller in the Intel 5000X MCH communicates directly with the first AMB it finds on each channel, that interface is actually only 24-bits wide per channel for a total bus width of 96-bits (24-bits per channel x 4 channels). The bandwidth part of the equation is a bit more complicated, but we'll get to that in a moment." More.
