CPU News Stream ▼

stands for Central Processing Unit. In a computer, there is at least one CPU, which many have one more more processing Cores, which can often be considered to be CPUs themselves. The modern concept of CPU is usually a silicon chip that performs two basic tasks: its control unit fetches instructions from memory and executes them and the arithmetic logic unit (ALU) computes basic math and logic operations. The CPU is a critical component in a computer.

Intel Readies 13W CPUs, Dives Deeper in Low-Power Territory

12/10/2012, Not so long ago, mobile processors from Intel had thermal design points (TDP) of 45W. TDP designates the energy that the chip and its cooling system are designed to dissipate. It is not really a measure of power draw, but both are correlated because...

Wii U developers already complaining about underperforming CPU

09/25/2012, Nintendo’s consoles aren’t known for raw performance, and the upcoming Wii U won’t change that. But Akihiro Suzuki, developer of the popular–and graphically intense–Dynasty Warriors, has already started to complain about what...

Ivy and Sandy overclocked, Sandy Bridge ends up cooler

04/30/2012, We’re dying to test some of the world’s fastest and most powerful processors. Ivy Bridge and Sandy Bridge are definitely on our list. So when we got the report that both chips have just been tested and overclocked until they burned, we were...

China’s Unified CPU Architecture, Why and When

04/27/2012, Part of the web was buzzing about the fact that China’s ministry of technology  is trying to define a ‘unified” processor architecture, based either on an existing platform, or a new one. By “processor architecture”, we mean...

Intel Shows 50 Cores Chip, wows to break Exaflop barrier

11/15/2011, While Intel has talked about its Many Integrated Core (MIC) architecture for some time, it has shown its 50 Cores chip for the first time today at the SC11 supercomputing conference. Codenamed Knights Corner, many 50-core chips will work as co-processors...

AMD Opteron 6200 CPU Has 16 Cores

11/13/2011, By launching its 16-Core Opteron processor, AMD makes history. It introduces the first 16-Core CPU running on the X86 micro-architecture. Based on the most recent AMD core design called “Bulldozer”, the Opteron 6200 is expected to run 25%-30%...

ARM Cortex A15, Alive

10/26/2011, This video (courtesy of ARMdevices.net) shows an ARM Cortex 15MP reference design chip running a build of Android. A reference design chip is built just to test (and prove) that the chip design works as advertised. ARM will then sell this design to...

Samsung to continue supplying A6 chips for Apple?

10/17/2011, Samsung and Apple aren’t on the best of terms, but this is probably something many are familiar with already, and what with Apple winning injunctions against Samsung, and Samsung having their injunctions denied, well, it doesn’t much to come to the...

Intel CPUs power consumption to fall off a cliff

09/14/2011, We attended the Intel Developer Forum’s (IDF) second keynote this morning (did you follow the live blog?), and the most important thing that you need to know is that Intel is making “low-power” its priority. Low-power is not a new theme:...

Intel CPU running on solar energy

09/13/2011, [IDF 2011] Earlier today, Intel showed us a computer processor (CPU) that was running on solar energy from a single small solar cell. Although Intel didn’t provide the specific voltage numbers, it’s not hard to imagine that a solar cell can...

AMD A4-3300 and A4-3400 APUs Introduced

09/07/2011, AMD has just launched two Accelerated Processing Units*(APUs)  in the entry-level segment. This new addition to the AMD line-up will allow AMD customers (PC manufacturers) to build more affordable systems that are still fairly capable in terms of gaming...
