The Nvidia GeForce GTX 980 is Nvidia’s latest and greatest graphics card featuring the company’s new Maxwell GPU architecture. Nvidia claims that Maxwell is able to maintain performance while delivering better power efficiency. Sure, the Kepler architecture brought some amazing improvements when compared to the infamous Fermi architecture, but it was less revolutionary than the Maxwell architecture which debuted last year in the GTX 750 Ti. Below, you can see a single SMM block diagram of the Maxwell architecture, followed by the full GM-204 architecture. Keep in mind that this is not the full-blown version of Maxwell. The GeForce GTX 980 is based upon Nvidia’s GM-204 GPU

Communication between cores on a computer chip becomes more and more difficult as the number of cores or processing units increases. Maintaining cache coherence, ensuring cores locally stored copies of globally accessible data is up to date is a problem that one set of researchers claims to have solved. A group led by Li-Shiuan Peh, MIT Singapore Research Professor of Electrical Engineering and Computer Science, brought a 36-core network-on-a-chip to the International Symposium on Computer Architecture. Her team’s experimental design uses an Internet like communication network to manage local memory stores. Each core has an associated router where data travels between cores in packets of
