AMD shows off Carrizo, declares it on time and coming in first half of 2015

ExtremeTech, November 21, 2014

When rumors surfaced several weeks ago claiming that AMD would launch Carrizo late this year, we attempted to deflate them with minimal success. Now, AMD’s John Byrne has taken to YouTube to demonstrate the new Carrizo APU and to confirm that both Carrizo and Carrizo-L won’t ship until the first half of 2015 — in line with original expectations.

More important than the shipping date is what Byrne had to say about the final product. According to him, Carrizo is the greatest single leap forward in performance per watt that AMD has ever launched, with an all-new graphics core and the aforementioned Excavator APU.

Analyzing Nvidia’s new AA: Can MFAA improve image quality without a frame rate hit?

ExtremeTech, November 20, 2014

Nvidia has released the Game Ready 334.75 WHQL graphics driver, with optimized support for World of Warcraft’s latest Warlords of Draenor expansion, Far Cry 4, Dragon Age Inquisition, and The Crew. Alongside those new titles comes support for a new capability that Nvidia touted when it launched the Maxwell family: MFAA, or Multi-Frame Anti-Aliasing.

What is MFAA?

The term antialiasing refers to a wide range of rendering techniques designed to reduce the appearance of jagged, crawling lines on a moving render surface. ...

Intel details new high-speed CPU-powered anti-aliasing

ExtremeTech, July 25, 2011

Intel, with a move that will likely take a little wind out of AMD’s heterogeneous computing sails, has detailed a new form of anti-aliasing that can be done in real time on the CPU. Called morphological anti-aliasing, or MLAA, it is actually nothing like the anti-aliasing you’ve come to expect from MSAA or FSAA.

Instead of rendering a larger image and downsizing, MLAA is basically a filter that is applied to every frame created by the game or application. In a similar way to the depixelizing pixel art algorithm, MLAA blends edge pixels with their surrounding areas. To do this, the MLAA algorithm looks for Z- and U-shaped edges, and then breaks them down into L-shapes, blending the pixels between the resultant L shapes.

World’s largest lithium-ion battery to be built in Southern California, dwarfs previous installations

ExtremeTech, November 20, 2014

Battery power developer AES Southland has announced a contract with Southern California Edison to deliver a 400MW lithium ion battery-based energy storage facility that will be capable of providing 100MW of power for a total of four hours. For comparison, when the State Grid Corporation of China teamed up with electric car manufacturer BYD to build the largest battery in the world, the stated capacity was 36MWh — less than 1/10 the size of the SCE facility.

That gap is so large it seems ridiculous, yet all available data points to this new facility as one of the largest, if not the largest lithium-ion battery storage facilities in the entire world.

NASA Explores New World Of Open Data

InformationWeek, November 12, 2014

NASA has been publishing a lot of data for a long time, but getting it into standard machine-readable formats is still a herculean task.

“That made more complicated — or, you might say, made wonderful — the job we were already doing,” NASA open innovation program manager Beth Beck said in an interview. “Big data is NASA — that’s what we have — but taking all that data and making it machine readable, that’s a big job.” Most of the data is already digital and readable by some internal applications created by NASA and its network of contractors. The challenge is finding it in a sprawling, decentralized organization and putting it in a form that others can use. Some important data is locked up in the form of PDFs of scientific articles, when a data analyst would much prefer structured XML or even a comma-delimited download of tabular data.
