Intel Reveals the Future of the CPU-GPU War
Arun Demeure writes "Beyond3D has once again obtained new information on Intel's plans to compete against NVIDIA and AMD's graphics processors, in what the Chief Architect of the project presents as a 'battle for control of the computing platform.' He describes a new computing architecture based on the many-core paradigm with super-wide execution units, and the reasoning behind some of the design choices. Looks like computer scientists and software programmers everywhere will have to adapt to these new concepts, as there will be no silver bullet to achieve high efficiency on new and exotic architectures."
It's a good design, it just doesn't seem like a good design for a video game system. It's a general purpose CPU attached to several CPUs that essentially are DSPs. DSP programming is very weird, and you need to at least understand how the device works on the instruction level for optimal performance. A lot of DSP code is still written in assembly (or at the very least hand-optimized after compilation).
It's very expensive to have DSP code written, when compared to normal CPU code, and video game manufacturers have been complaining that the cost of making a game is too high. Also, most of the complexity in a video game nowadays is handled by the GPU, not the CPU. Now the cell would be great for lots of parallel signal processing, or some other similar task, and I bet it could be used to create a great video game, it would just be prohibitively expensive.
The cell is a great solution to a problem. However, that problem isn't video games. A fast traditional CPU, possibly with multiple cores, attached to a massively pipelined GPU would probably work better for video games.
