| unaveragejoe said: One thing I think we can put to rest is this. As far as the issue of the Wii U GPU being a AMD 4000 line or 5000 line. It would definitely be the 5000. I think if, based off anything it would have to be the 5550. The 4600 line has two 400Mhz RAMDACS. It's also fabbed at 55nm. The 4600 is probably closer to 70 watts under a full load. The 5550 is 550 Mhz has the 320 SPU 15 TU 8 ROP and fabbed at 40nm. It has a maximum board power 39 Watts. I think it used the 5550 as a base with some newer tech added features. Either that or built straight from the ground up which I think unlikely. |
Looks like it lines up very well. One thing that's bothered me is, the estimate of 12.8GB/s data throughput to the RAM. This lists DDR3 with this particular card at 24.5 – 28.8 GB/s.
Here's the kicker: "Drive three displays simultaneously with independent resolutions, refresh rates, color controls, and video overlays ", this is necessary for the Nintendo-stated capability of running a primary display, as well as 2 Gamepads at the same time.
To be clear: The 4000 series cards CANNOT run 3 displays simultaneously, while Nintendo has stated the WiiU is capable of running 3 displays. It cannot be a 4000 series card.
