Here's why the Wii U's CPU is more powerful than PS3's CPU

I have to clear this up since no one else had. The CPUs are 64-Bit. GPUs are 256 bit. The dreamcast used a 32 bit CPU and 128 bit GPU.


You're absolutely right about CPU's being 64-bit (does anyone even make 128-bit CPUs?), but modern GPUs are not necessarily 256-bit. I believe they have 4-channel vector units comprised of four 32-bit FP ALUs. So, I guess you could say they're 128-bit vector processors. I think some newer GPUs have even eliminated vector units in favor of scalar 32-bit ALUs, but I'm not up to date on recent GPU tech.


Yup, I believe you are right about GPUs not having robust vector-math units anymore. This is due to those being built into modern CPUs these days. Which brings me back to the Wii U CPU, it's a VERY old CPU architecture, old tech, and not optimized for modern games programming (it's essentially missing the vector-math unit, along with having a negligible SIMD instructions set, it also doesn't help that the clockspeed is the max the CPU is capable of, so it's not comparable to something like a i7 where idle it's 1.8Ghz but that doubles when some cores are not being used).

GameFAQS users are far too sensitive.

Sorry, my bad. My information was based on older sources. And I meant to say PCB. Dunno know for the life of me why I said die.
