Ati: Xbox 360 will outperform PS3

Filed under
Gaming

In an interview with Web site bit-tech.net, ATI Developer Relations Manager Richard Huddy waxed technical about Microsoft's upcoming Xbox 360 and ATI's role in the machine. The 360 will be using ATI's Xenos graphics processor, and Huddy's job is to chat with potential developers and help them develop the tools that best use Xenos' capabilities.

With regards to the console's architecture, Huddy says, "It's way better than I would have expected at this point in the history of 3D graphics." He sees the unified pipeline, rather than segregated pixel and vertex engines, giving the 360 a huge a huge advantage in accessible processing power.

Huddy goes on to shed some light on backwards compatibility. Each Xbox game is written with specific Xbox hardware in mind, and the 360's move to PowerPCs and ATI graphics doesn't jibe with the Xbox's Intel chips and Nvidia graphics processors. To add to the difficulty, the 360 wasn't designed for backward-compatibility early on in development.

To solve this, Microsoft has implemented the use of emulator programs that will allow the Xbox 360 to play Xbox games. According to Huddy, "emulating the CPU isn't really a difficult task. ...the real bottlenecks in the emulation are GPU calls--calls made specifically by games to the Nvidia hardware in a certain way. General GPU instructions are easy to convert--an instruction to draw a triangle in a certain way will be pretty generic. However, it's the odd cases, the proprietary routines, that will cause hassle." Once complete, the Xbox emulators could come pre-loaded on the unit's hard drive or will be downloadable via Xbox Live.

Huddy also dispels the notion of the PlayStation 3's higher graphics clock speed (550MHz versus the 360's 500MHz) means that Sony's console will outperform the Xbox 360. He believes that its ATI's unified pipeline that will make the biggest difference between the Xbox 360 and PS3. ATI archrival Nvidia, who is providing the RSX graphics processor for the PS3, has chosen not to go the route of a unified pipeline.

"This time around, [Nvidia doesn't] have the architecture and we do, so they have to knock it and say it isn't worthwhile. But in the future, they'll market themselves out of this corner, claiming that they've cracked how to do it best. But RSX isn't unified, and this is why I think PS3 will almost certainly be slower and less powerful."

Open-Source Radeon 2D Performance Is Better With Ubuntu 14.10

While we're most often looking at the OpenGL 3D performance of the Linux graphics drivers, in the tests currently being done of Ubuntu 14.04 LTS vs. Ubuntu 14.10 are also a number of 2D graphics benchmarks. In the article today are our 2D benchmarks between Ubuntu 14.04.1 and Ubuntu 14.10 for various AMD Radeon graphics cards and it shows off significant performance improvements. Read more

KDE With Theoretical Client-Side Decorations, Windows 10 Influence

KDE contributor and graphics designer Ken Vermette has penned an interesting series of KDE "What if..." articles where he talks about (and has some visual mock-ups) about what KDE might look like with client-side decorations along and separately if KDE were to use Windows 10 design components.

Pondering FOSS foundations

In the case of the Document Foundation, the LibreOffice project needed an independent, solid and meritocratic entity dedicated to support it. In other terms, the OpenOffice.org community wanted to be its own boss and stop relying on corporate – or even third party – good will. If you attend the Community Track on the 31st you will be able to learn more about the Document Foundation and the other entities, but my message here is that while there is no silver bullet in these matters, forcing a community be hosted or to bend to a software vendor never works. It bends if it wants to; it goes whereever it wishes to go. In the case of the Document Foundation, independence and community rule prevailed over convenience; today the results do not need to be proven anymore. But it does not mean we hold the truth more than anybody else: we just ensured the community was in charge. Read more
