i havent had time to change my sig i will do it later, and all i'm saying is wiiu ius simialer current gen interms of performance slighty better, and we have heard this from many developers, not to mention the games not looking better the current gen. |
nintendo stopped releasing specs once they found out the public was too stupid to understand them. There are still morons convinced the ps2 is more powerful than the gamecube.
Using your logic you might as well call i7's 'beefed up pentiums'. There are nowhere NEAR as many 'new' cpu designs as you think there are. They are near ALL old designs 'beefed up'. In fact, older designs are revisited all the time to see if new technology can bring them back better than newer onez.
The g3 was a damn good processor core, that was shelved because the technology of the time couldnt mantain cache coherency of such a short piped architecture (no multicore), and couldnt increase clock speed, again, because it was such a short piped architecture. The g4 was a g3 with an altivec simd unit bolted on, and the g5 was a red hot disaster.
Fabrication technology has shrunk enough to allow clock speed increases, and edram technology improvements have managed to allow practical cache coherency for multicore.
The instructions per clock on this design is still damn impressive to this day. Literally sitting just behind the jaguars used in xbone/ps4. At around 2.4 vs 2.7 And thats just using stock 750cl ipc. We have no idea what kind of increases in ipc the increase in size to the MASSIVE core caches in espresso have made. But we do know the smaller cache increases from bobcat to jaguar improved ipc 15%.
So yeah, its sitting pretty in ipc even next to ps4/xbone.
Its biggest weakness is its complete lack of modern simd, which is pretty huge today.
Yet the little Mcguffin doesnt seem to even care. Its destroying simd resource hogs and surprising devs who actually try left and right. This isnt just surprising, it shouldnt be possible.
RAD tools just stated they were completely taken by surprise when they found nintendos custom 750 design can run, in full hd the simd or die video codec bink 2. They were expecting to have use the gpu to make up for the lack of simd. But no, the little non simd cpu just eats through it. Hell, BROADWAY could do it too! (640 480 of course)
WTF? HTF?
Simd is like a factory line, it works by being... say, thousands of little processors doing different parts of the same job at the same time, to speed up the job. You can see why it would be considered so important.
Nintendo's custom ppc750 doesnt have the factory... But its still doing all the work in time.

Bink 2 simd, or go kill yourself.
Bink video change log.

Added Wii-U support for Bink 2 - play 30 Hz
1080p or 60 Hz 720p video! We didn't think
this would be possible - the little non-SIMD CPU
that could!
The notion of a non simd cpu muscling through this is ridiculous... No wonder they were surprised. I still have trouble believing it. Could have sworn it would remain bink1 because of its weak simd, or need gpgpu assistance. I always wondered why nintendo didnt add simd to the design. I thought gpgpu was meant to pick up the slack, but there doesnt seem to be near as much slack as I thought.
Its just plain a great cpu core. And its now possible to build up on it again. Nintendo was actually pretty smart here. You can easily attach simd units add more cores, and after a die shrink increase clock speeds to keep it going, competently into the future. I dont think this gen is the last weve seen of nintendos custom g3.
And I dont think its a bad thing. Little bastards earned it.
