Edit: Oh and in response of the wii being capable of higher resolutions than 480p. Yes I believe it could. WHile it won't look too nice to games pushing the wii in 480p and isn't really pratical. I do believe games like fps' would benefit a little from 720p, but anythng else on the wii would have less than it would in 480p and wouldn't be pratical. I believe maybe some sub hd resolutions that alot of ps360 games have is a more better fit. Also nintendo never gave official specs. All of the specs came from the developers of the chips or 3rd parties, but none of them went into detail. There is alot we don't know about the wii's hardware, because of this and analysis' won't be too acurate until more is known. I will try to make mine as accurate as possible. |
I think you are overestimating Wii's graphical capabilities. According to wikipedia, the Wii's framebuffer is similar to Gamecube's (3MB split into 1MB texture memory and 2MB framebuffer). Higher resolutions need more framebuffer memory as there are more pixels to fit into the framebuffer. 720p is 1280x720 = 921600 pixels wheras 480p is 640x480 = 307200 pixels. Now, I don't know what kind of colour format they're using (some say it's YUY2 which means 16bits per pixel) but you have to multiply the number of pixels by the pixel depth which is something between 16bits and 32bits (2 bytes - 4 bytes). Then you'd probably have to double that, if they're double buffering (most probably) and you'll see there's not enough framebuffer memory for 720p output. Even if it had a bigger framebuffer, it would have to have enough fill rate to actually render those pixels.
PS. Oh, and take a look at this, these guys seem to know much more than me: http://forum.beyond3d.com/showthread.php?t=46169 |
Actually, that's just the minimum for the Wii. It also has access to 24MB of additional RAM, which can be allocated as developers see fit (as either textures, frames, or main memory).
And the VRAM may also have access to the 64MB of GDDR3 RAM, but even if not, the Wii has a lot more room for a frame buffer than the GC did. If it didn't, RE4 Wii would not be able to have a true widescreen mode.
