ATI Radeon HD 4850 Linux Performance

Filed under
Hardware

Last week we exclusively shared the steps AMD was taking to make an evolutionary leap in Linux support with same-day support for their brand-new Radeon HD 4800 series, Linux drivers shipping on the product CD, some manufacturers showcasing Tux on the product packaging, and their proprietary Linux driver reaching a feature parity with their Windows driver. We had also shared that the Radeon HD 4850 works with open-source xf86-video-ati driver since day one. Now that we have had time to complete testing of the Radeon HD 4850, today we are sharing the first Linux results from this brand-new ATI graphics processor. Before you think the Windows and Linux performance is equal for the Radeon HD 4800 series, this isn't the case, at least not yet.

While you are likely already familiar with the ATI Radeon 4800 series, it's the industry's first TeraFLOPS GPU, the RV770 contains 800 stream processors, and the Radeon 4870 is the first graphics card deploying GDDR5. The Radeon HD 4850 has its RV770 core clocked at 625MHz with 110W power consumption while its big brother, the Radeon HD 4870, is clocked at 750MHz and has 1.2 TeraFLOPS of computing power, but its maximum power consumption is 160W. Both of these new graphics cards have 512MB of video memory, however, some AIB partners may opt for using 1GB. Other features include a PCI Express 2.0 x16 interface, Unified Superscalar Shader Architecture, Avivo HD, OpenGL 2.0 support, ATI PowerPlay, and CrossFireX Multi-GPU Technology. Making up the RV770 core are 956 million transistors on a 55nm fabrication process.

Mozilla Marches Ahead with Ads for Firefox

This November, Mozilla is up for renegotiation with Google for placement of Google search as the default search in Firefox and for the related subsidies that Google pays Mozilla, which reached almost $300 million last year. That comprised the majority of Mozilla's income. With Chrome establishing itself as a leader in the browser wars, its unclear what relationship Google will continue to pursue with Mozilla. Read more

What happens when a non-coder tries to learn Linux

The Linux Foundation has created all of the content for the course, including the videos, written text, activities, and labs. It's clear to me that their content team has made an effort to space out the videos between the written material in a way that gives you a break from endless reading. Also, each video is only approximately 30 seconds to 2 minutes long. They avoid getting into the weeds too much at once, giving you chunks of knowledge, letting you test it out, then moving on to another topic. Each chapter points out that as the course progresses, you will go into further depth with each topic. Read more

Jailhouse 0.1 released

This release particularly means full exploitation of VT-d DMA and interrupt remapping to isolate assigned PCI devices from the hypervisor and foreign cells. Moreover, the usability of Jailhouse was greatly improved by the introduction and continuous extension of a generator for system configuration files. Finally, a framework for writing basic cell applications is available now. With a few lines of C code you can set up timer interrupts, read clocks or configure PCI devices for the use in simple bare-metal real-time applications. Read more

Ubuntu Launcher 0.5.5 for Android Will Transform Your Phone in Ubuntu – Gallery

Many users might have something against the Unity desktop environment that's being used in Ubuntu, but the truth is that Unity comes with a great app launcher. Coincidentally, the same kind of launcher might work very well on phones and a similar implementation is being done for Ubuntu Touch. Read more
