Your max is a little off. Broadway runs a 723 MHz. Assuming your 32 times slow statement is corret, If it was upped to 3 core then it would only need to run at 2 MHz to match the xenos. 2.5 would put it ahead.


Wait a seccond that doesn't sound right, each Xenon core should obliterate the Broadway at the same clock, it has a SIMD: VMX128 with 2× (128×128 bit) registers and SMT capabilities, plus a more modern instruction set.

The actual numbers are 2.9 Gflops for Broadway at 729 MHz (the reported clock of the Wii). 76.8 GFLOPS for the Xenon so ~26X faster in terms of flops. So Xenon 25.6GFlops per core at 3.2GHZ is over 8.8X faster than the Wii's Broadway at 729Mhz in terms of raw Flops so wouldn't each Broadway core wouldn't it have to be clocked at 6.435GHz to match it with tri core vs tri core?

But I don't think anyone is suggesting that it's just 3 overclocked Broadway cores.

Forgive my ignorance, but what exactly does the number of FLOPS (FLoating point Operations Per Second, right?) determine? What aspect of performance does it contribute to?

Because IIRC, the PS2 CPU had more 4 times more FLOPS than the original Xbox's, and more than double the Wii's, yet the PS2 is regared as the weaker system.

basically the number of floating point numbers (http://en.wikipedia.org/wiki/Floating-point) that a proccessor can proccess each seccond. It doesn't really mean all that much for most aplications but it's probably the most widely used performance metric in terms of raw performance. It only really mesures one aspect of CPU performance tho. The PS2's CPU had two coproccessors dedicated to doing floating point math, but the tasks that were performed on them were mostly tasks handled by GPU components in the Gamecube and Xbox.

The Wii U has a very small box which is only 1/3rd larger than the Wii by volume. It isn't going to be extremely powerful because it is extremely small.


As you should know, size and power consumption aren't necessarily good indicators of processing power ...

With how clock speed has an exponential impact on energy consumption, what do you think would happen if the XBox 360 CPU was modified and underclocked at 1.6GHz? While it would have resulted in the XBox 360 having a CPU which had (essentially) half the processing power, with similar modifications to the rest of the XBox 360 it could have probably been released in a system that wasn't much larger than the Wii. When doing something along these lines you're trading off the performance per dollar to increase the performance per watt, and lowering overall performance.

This is (essentially) the trade-off that has been made on high end laptops ... You get a laptop that has a CPU which is nearly as powerful as the desktop CPU but is much more expensive.

Now, I doubt Nintendo has gone to any extremes with this so I doubt the Wii U is amazingly powerful, but the Wii U is about the same size as consoles were traditionally and most of these systems performed reasonably well.

The Wii U is likely more powerful than the current generation consoles with slightly better technology but it won't be a huge difference. It is likely to be between 1.3-2.5* more powerful than the Xbox 360 which is bourne out by the games seen thus far and the more credible rumours. I do expect the cost of the system to be between $199-249 and with the Yen vs dollar/euro conversion as it is that doesn't pay for expensive systems.



Tease.

I love how it has expresso as name and people actually believe it's not someone trolling them.

As to what "bit" systems we're on: PS3 and Xbox360 both use 64-bit processors. Broadway is only 32 bit. CPUs have not moved in the consumer market passed 64bit.

Making it 3 cores would make the performance  9 Gflops at 729 mhb. Triple the power and tha twould be 27 Gflop at 2.2 Ghz.

Also, to make this three core it would clearly have to have major arhictectural redesigns which would mean larger/faster registers and a larger/faster cache as well as a more enhanced veloctiy engine features along the lines of SSSE3 or whatnot.

We still have cofirmation of it being Power7 based so its reasonable to assume that is the Broadway Architecture with Power7 features.

False, Broadway is a 64bit processor.

  • 90 nanometer process technology
  • Power Architecture core, specially modified for the Wii platform
  • IBM silicon on insulator (SOI) technology
  • Backward compatible with the Gekko processor
  • 729 MHz
  • 32-bit integer unit
  • 64-bit floating-point (or 2 × 32-bit SIMD, often found under the denomination "paired singles")
  • 64 kB L1 cache (32 kB instruction + 32 kB data)
  • 256 kB L2 cache
  • 2.9 GFLOPS

External bus

  • 64-bit
  • 243 MHz
  • 1.944 gigabytes per second bandwidth

Only the integer unit is listed at 32 bit.

I personally think you're aiming low ...

With the Wii U CPU being based on a Power7 processor (of some sort) and the GPU being based on a R7xx (of some sort) I suspect that after a quick and dirty port of the XBox 360 code base most games (probably) run about 50% to 100% faster than they did on the XBox 360. Developers who take the time to understand the Wii U architecture and take advantage of its advanced features will probably get 50% to 100% greater performance; and several of these features (like Tessellation) will improve the preceived performance.

I love how so many people are talking about previously 'confirmed' specs. Those were old rumors that were repeated over and over so they became 'fact'. And somehow because those old rumors were different from this new one, that the current rumor is automatically 'fake'... even though we're very close to launch, and the specs would seem to match the capabilities of the machine from what we've seen so far. These are the most realistic numbers that have dropped, and I'm inclined to think that it's pretty spot on.

Also, for all the people waiting for Nintendo to confirm the specs.... Nintendo has never confirmed specs, and there's no reason to think that will change. You'll be waiting until the end of time.

We'll know for sure how close this rumor is to the real thing after Wii U launches and it's busted open.

Yeah, IBM is know for making shit up about projects they were working on ...

I bet they got a big LOL out of trolling Nintendo fans by claiming that the Wii U would use a Power7 processor.

Got any proof of them TROLLINg before?

It's important to pay attention to the most consistent rumors sometimes, and realize that even a guy from IBM can be wrong.  Like I said before, these specs are most likely pretty spot on.
