AMD Radeon HD 7970 On Linux

Filed under
Hardware

You've may have heard or seen that AMD introduced the Radeon HD 7970 graphics card this morning as their first product built in their "Southern Islands" family and is based on their new GPU architecture, but how well does it work under Linux for the open-source and closed-source AMD Catalyst Linux drivers?

First of all, the AMD Radeon HD 7970 graphics card is a 28nm beast that boasts 2048 Stream processors, 128 texture units, 925MHz core clock, 3GB of 5.5GHz effective GDDR5 memory on a 384-bit bus, and is their first product of GCN (Graphics Core Next), their new graphics architecture. The launch cost on her is $549 USD. GCN represents the largest architectural change for AMD since they launched the R600 GPU several years ago.

So how does the Radeon HD 7970 "Tahiti" work under Linux?

  • Container-friendly Alpine Linux may get Java port
    A proposal floated this week on an OpenJDK mailing list calls for porting the JDK (Java Development Kit), including the Java Runtime Environment, Java compiler and APIs, to both the distribution and the musl C standard library, which is supported by Alpine Linux. The key focus here is musl; Java has previously been ported to the standard glibc library, which you can install in Alpine, but the standard Alpine release switched two years ago to musl because it’s much faster and more compact.

Jolla inks exclusive license to kick-start its Android alternative in China

Mobile OS maker Jolla, whose Sailfish platform remains one of the few smartphone alternatives in play these days, has signed an exclusive license to a Chinese consortium to develop a Sailfish-based OS for the country. Jolla says the Chinese consortium will be aiming to invest $250M in developing a Sailfish ecosystem for the country, though it’s not specifying exactly is backing the consortia at this point, nor over what timeframe the investment will happen — beyond saying one of its early investors, a local private equity investor Shan Li, will take a “leading role” in building it up. “There are very big players behind it,” Jolla chairman Antti Saarnio tells TechCrunch, speaking ahead of a press conference held to announce the news here at the Mobile World Congress tradeshow in Barcelona.
