| Mnementh said: Is this discussion now about emulation? And well, many posters don't know much but feel entitled to say something anyways. As a programmer I know something, but that something is enough that I know I can't decide if WiiU or PS4/XBO are easier to emulate. |
Depends what the target platform is going to be doing all the emulation.
It's easier to translate instructions from the Playstation 4 and Xbox One to PC, because well. They're all x86.
You don't have to cut and chop instructions, then translate it. Essentially what might take 1 Cycle to perform natively on PowerPC might take multiple on PC/x86 once you go through all those steps.
Intel actually had a good solution to that with it's Atom CPU's in Medfield: Binary Translation, of course it still comes with a performance penalty and it only translates ARM to x86.
Heck, you just have to take a look at the origional Xbox Emulators, they're stupidly fast, faster than PS2 emulators, granted most of the Origional Xbox's game library was released on PC anyway, but even when comparing the Console to PC games of the same era, there really wasn't a massive deviation in CPU requirements at the time.
The GPU is a little different, in the PC space other parts of the GPU will take on the task of older generations fixed function hardware.
For example, the TnL unit in Direct X 7 graphics processors like the Geforce 256, was supplanted later on in successive generations of GPU's by performing the same functions in the Shader Hardware, same thing goes for the Vertex Shaders, so from a technical perspective that shouldn't be a drama.
It's when you start getting into the smaller details like the eDRAM on the Xbox 360 and the extra hardware in the GPU, that makes it a little less clear on it's ease of emulating.
The Graphics Core Next GPU's in the next generations should in theory be easier to emulate as they aren't as large of a deviation from their PC version in comparison if you were to compare the Xbox 360's GPU to the Radeon x19xx and Radeon 29xx series.
So in the end, the WiiU will be more difficult to emulate on PC than the Xbox One or Playstation 4 and the WiiU will also come with it higher hardware overheads.
