cores

More cores mean better performance, right? That's not what Amdahl says. Learn one of the foundations of parallel computing in "Amdahl's Law." Prepare yourself for math.

An Intel Researcher said this week that the company's 48-core Single Chip Cloud Computer could easily scale to 1,000 cores or more.

AMD's new Bulldozer and Bobcat cores, slated for release in 2011, utilize new designs to achieve improved performance at reduced power levels.

TechWorld: "IBM has strengthened its hand in the Unix business with new systems based on its Power7 processors, including a server for large enterprises that scales to 256 cores."

Conceivably Tech: "Almost five years ago, Intel ran into a heat wall and decided it had to commoditize its processors and focus on the brand rather than the clock speed.

Processors received sequence numbers..."

We're now starting to see some very different approaches to servers, both with more specialized products based on GPUs, and with those based on low-end, rather than high-end, CPUs.

Linux Magazine: "The concept is based on building clusters using low cost nodes (less than $500 each). Because lower cost nodes will run slower and have less cores than the big server nodes, they would need to be smaller and use much less power."

LinuxDevices: "Intel announced six new 32nm processors intended for ultra-thin laptops. Topped by the Core i7-660UM, with a clock speed of 1.33GHz and "TurboBoost" frequency of 2.4GHz"

Hardware Central: "But there are still some applications, such as massive calculations or data searches and sorts, where Step B requires the results of Step A, and in that case, a single 5GHz core will get you there faster than two 2.5GHz cores."
