Honda:The design of PS3 is like AV console.
Ken:Yes, because Playstation is not videogame console. I have never said PS as videogame console.
PS3 is the product which at last arrived at the aim that I thought about when I established SCEI.
PC was a computer as a work tool until now. It was merely transplanted from main frame. Against this, PS3 is the computer which was made to realize entertainment.
We made new GPU in cooperation with NVIDIA.I found a kindred spirit in NVIDIA in particular. I drew a future road map with Jen-Hsun Huang (NVIDIA CEO). An entrance of the road map is RSX. The person who does not know RSX well seems to think so that this is hash-up of GPU for PCs, but, in fact, is different for the architecture at all. Include Mr. Kirk (a NVIDIA architect), and people of NVIDIA are people liking that draw a dream. At this point, there is a part to sympathize with each other, and we talk to still do a new thing.
RSX is not subspecies of a chip for PCs of NVIDIA. Cell and RSX have close relation and both are accessible for main memory and VRAM seamlessly. Cell can access VRAM in the same way as main memory, and RSX can treat main memory as a frame buffer, too.
The reason why we made PS3 such architecture is to get rid of a copy and operation of useless data between Cell and RSX. RSX can refer to a result to simulate in Cell directly and Cell can refer to form of the object which RSX made shadeing directly too. Shared memory cannot do such an act even if it can do rendering beautifully and complicated shading.
