| vanguardian1 said: 2 problems. A) IIRC, the Wii is hardware-locked at 640x480 or 720x480, depending on your settings (Nintendo did this themselves) B) The 3mb Frame Buffer that is physically a part of the gpu itself would hinder the functionality of the hardware, if it's even capable of functioning at such a resolution (IIRC the PS2 and xbox use the system memory itself for the frame buffer, while it's a stand-alone piece of memory on the gamecube/wii gpu designs). |
a) There's no such thing as 'hardware locking' for resolutions. It can be changed via firmware as long as the GPU has the needed fillrate and bandwidth with the memory. And while there's 720x480, the Wii's actual resolution for widescreen is 854x480.
b) The 3MB embedded RAM figure is an assumption, not a fact. That's what the GC had, and now the design of the GPU is different, because in the Flipper (GC), it WAS all on a single chip (embedded RAM, sound, I/O and GPU). With the Hollywood (Wii) it has been split into TWO chips. And you are not remembering correctly, because, while the Xbox lacked a dedicated frame/texture buffer, the PS2 used embedded RAM too. The Xbox 360 uses embedded RAM too for frames/textures (and in the 360 it is physically part of the GPU) and it can access the main system RAM for GPU usage as well.
Thanks.
