| Aielyn said: So... if they found that VLIW5 was inefficient, and VLIW4 increases efficiency, why is it then assumed that VLIW5 is being used in the Wii U? And what impact would that change have on the Wii U GPU interpretation, if possible? Keep in mind, I'm not arguing for VLIW4 - I'm just trying to understand the reasoning behind each of the claims being made, because at this time, I'm getting somewhat confused by terminology and the details of GPU design. |
The design step from VLIW5 to VLIW4 isn't that old at all. Probably happened around the same time the WiiU gpu design was started, so anything is possible.
I must admit that the gpu die picture is irritating. Usually I start from the data/address bus to figure out what probably is in a chip. With the WiiU gpu, I can't even FIND the busses. Somehow reminds me of the first processor dies which were "random structures"...
