I personally don't believe that if it was a new design that they would go 'whole retard' and make it slow and big and expensive at the same time relative to what they could have released. I have far too much faith in Nintendo for that to happen. What I do believe however is that the rumours are talking about the CPU performance and the CPU performance is relatively similar to what we have with the current generation consoles. Where the NES 6 stretches it's legs is with the GPU and memory bandwidth and optical drive speed as well as overall memory size or in other words the easy improvements which are noticeable from a user perspective that show a good price/effect ratio.
So if the current generation is roughly speaking:
- ~300M transistor GPU
- ~300M transistor CPU
- ~512MB RAM
- ~50GB/S overall bandwidth
- ~12MB/S optical drive streaming speed
- ~4GB flash
Then the NES 6 could look like this:
- ~800M transistor GPU
- ~400M transistor CPU
- ~1GB RAM
- ~75GB/S overall bandwidth
- ~24-36MB/S optical drive streaming
- ~8-16GB flash
Im not talking exacts here im just looking roughly at the spec of the combined HD systems as developers target them relative to what the NES 6 ought to look like.
Overall they:
- Gain performance from increasing the number of transistors.
- Gain performance from every transistor due to process improvements.
- Gain performance from supporting technology such as DX10, streaming speed of drive, RAM for textures and speed of RAM and any other technology they may care to implement such as ED-RAM etc.
So yes even minor improvements stack up and go a long way when you add them all together.
