[QUOTE='[EG] Pepper;38665928']Not only that, x86 is a pile of shit.[/QUOTE] x86 is just an instruction set, not an architecture. The architectures that implement x86 have improved so drastically in ten years. You can barely compare an Ivy Bridge with a Pentium 3. Intel has been doing amazing research and development. The only really bad thing about x86 in general is that the TDP on most architectures is extremely high.
[QUOTE=ShaunOfTheLive;38680239]x86 is just an instruction set, not an architecture.[/QUOTE] Eh, architecture usually refers to the instruction set architecture. What you're describing afterwards is the microarchitecture (which implements an ISA). I still think x86's support for useless legacy shit (real mode) is one of it's biggest drawbacks, and one of the main reason why I don't bother researching interesting low-level x86 topics (creating operating systems, Xbox emulation).
[QUOTE=Killuah;38653471]If what the wiki says is true and it uses a WATSON like processor architecture it is a [url=http://en.wikipedia.org/wiki/POWER7]Power7[/url] like CPU and that would mean word around the corner is wrong.[/QUOTE] The Wii U is speculated to use a derivative of the PowerPC 750 core (which the original Wii used), not a POWER7 chip which is several generations newer. The word about it having no SIMD would make sense because the PPC 750 core doesn't. It also has a relatively weak FPU, further crippling performance. To put the PPC 750 in an age perspective, it was the CPU used in the Power Macintosh G3 in 1999. This would make the CPU design nearly 14 years old.
[QUOTE=bohb;38681509]The word about it having no SIMD...[/QUOTE] Except it does. 2×32-bit. Exact same as the GameCube and Wii.
[QUOTE=Glitchman;38640168]I feel like this really doesn't matter. I also own a 360 and a killer PC, so I would want a Wii U for the games you KNOW will be good, that never fail you. Mario, Zelda, the Mario Karts, Mario Party, ect. They have always been great fun, especially with other people. Or if you have friends who are more casual gamers, you can share stuff like this with them. I'm not going to sit around with my family and play CoD. So graphics in this case, really don't matter much. If they find fun ways to use the wii U (im sure mario party will) it'll be great. Also, Rayman Origins was the best 2D platformer ever made (imo) can't wait for the new one.[/QUOTE] Yeah. Why would anyone buy some crappy modern warfare fps shoot em up game when you can just buy that for your PC. You buy Nintendo consoles for Nintendo games. no console is going to please the facepunch ~pc gamer~ crowd anyway.
[QUOTE=sixtyten;38681708]Except it does. 2×32-bit. Exact same as the GameCube and Wii.[/QUOTE] Nope. The Gekko core in the Gamecube doesn't have dedicated SIMD units, and it also doesn't have a full SIMD instruction set. The FPU in the Gekko was modified from the original PPC 750 core to process some SIMD operations (in this case it can execute two 32 bit SIMD operations since the register sizes are 64 bits wide.) There is very little information on the Broadway core (used in the Wii) other than it's likely just a die shrink with some minor improvements to increase the clock speed. Since the Broadway core is backwards compatible with the Gekko, it's really unlikely they made any significant changes to the FPU or the core in general to risk breaking compatibility with the older CPU. Since the Wii U CPU is likely still based on the PPC 750 core, they could either go with adding on to Broadway (again more backwards compatibility) or starting with a stock core and going a different direction with it.

[QUOTE=Zephyrs;38677845]So ultrabooks spontaneously cause nuclear explosions?[/QUOTE] no, they use Low Nm cpu's -_- made by a different company. and also use the bottom of the laptop for passivecooling. and yes. some do get very hot
