But as you say a G3 class CPU won't cut it. Actually, GPU acceleration can be a very big thing. I have a dual core, Core2 laptop at 2.4GHz, which can just barely play back standard 1080/60i video... forget 1080/60p. Even on my six core AMD desktop, 1080/60p playback can go as high as 60% of all CPU, depending on which player you use. But run a player that uses GPU acceleration (even Windows Media Player, in Windows 7), and the CPU load drops down to about 6%. That's via the DXVA 2.0 API, which isn't general purpose computing like OpenCL, but dedicated specifically to video rendering. And this is with a nVidia 8800GT GPU... hardly the latest thing. This is also why I loved the idea of AmigaOS for PPC on the PS3. The PS3 CPU is no match for even a cheapish desktop (3.2GHz, but very simple design for a PPC), but between the GPU and the SPEs, the PS3 can decode multiple HD streams.

STI CELL vs Intel Core i7

From http://forum.doom9.org/archive/index.php/t-109002.html

"under XMB, they managed to decode FullHD H264 clip up to 50Mbps with only 3 SPEs."

Toshiba's SPE based solution includes H264 decode/encode hardware.

From http://forum.doom9.org/showthread.php?t=157701

"The Cell is a pretty slow CPU. It takes roughly 2.5 cores (out of 8) to do realtime 1080p H.264 decoding with a highly optimized decoder. A fast i7 can do that with about ~0.4 cores (out of 4 or 6)."

I think that one thing that Hyperion are wary of is piracy.
This is why they stick mainly to "dongled" hardware.
If you have any options to prevent this then it could open the door to
later ports down the road.

Many Amigans wish to run AmigaOS on a common, yet powerful platform like PS3.

- Do you think porting AOS to PS3/PS4 is a viable project?
- Is Sony approachable in this sense?
