| AMD sheds light on High Bandwidth Memory in new Radeons, pokes Nvidia |
May 19, 2015 - 6:38 PM - by TechSocial |
More than seven years in the making, AMD on Tuesday unveiled what it believes will be a game-changing technology: a superfast, stacked chip technology called High Bandwidth Memory. Even better, the company crowed: Nvidia is at least a year behind it. |
Using stacked RAM chips that communicate through tiny holes, High Bandwidth Memory offers three times the performance of traditional GDDR5 that’s used by GPUs today and drastically reduces power consumption too, said AMD Chief Technology Officer Joe Macri, who oversaw HBM’s development.
Why this matters: A graphics card’s memory bandwidth matters as much to game performance as the graphics processor. An increase in memory bandwidth almost always means more performance, too, when coupled with changes to the GPU.
Modern graphics cards drink memory bandwidth like a big-block V8 drinks gas. The problem is the current memory, GDDR5, is rapidly approaching the point of diminishing returns, Macri said. To add more memory bandwidth using GDDR5 would consume too much power to be an effective performance boost.

| Tsu, the Tidal of social networks, pays you for posting |
May 11, 2015 - 11:25 AM - by TechSocial |
People are tired of being commoditized, sick of their photos and posts and life stories being used to sell advertising. But few social networking upstarts have been able to capitalize on this, because even people who loathe Facebook won’t leave it. But Tsu (pronounced “sue”) is taking a different approach: Use ad dollars to pay users. Share the revenue with everyone. |
Tsu, which bills itself as “the people’s social network,” launched last fall, shortly after Ello catapulted into our collective conscious and then promptly faded away. The network has been flying under the radar, gathering more than 3 million users through an invitation-only system, and recently debuted an overhaul of its website and mobile apps with new creation and discovery tools.
Tsu CEO Sebastian Sobczak compares what his network is doing with what Jay-Z’s new streaming service Tidal has done for musicians. Tidal shares equity with artists who get in on the ground early, to give them more of a financial stake in the success of streaming. Tsu shares its revenue, not equity, but the principle is the same: Give money to people who create content.
