I'm the exact same, I commute to and from work, and I'm rarely riding in a car long enough as a passenger to warrant gaming on my phone. I do take occasional road trips and flights where I just resign to watching movies on my phone as I hate on screen buttons.
Anything less than the X2 is a misstep, absolutely, for BOTH power efficiency and raw grunt I agree totally.
However, Nintendo has historically redsigned their mobile system fairly frequently and erratically:
- 1989 Gameboy
- 1998 Gameboy Color
- 2001 GameBoy Advance
- 2003 Gameboy Advance SP
- 2004 Nintendo DS
- 2006 Nintendo DS lite
- 2008 Nintendo DSi
- 2009 Nintendo DSi XL
- 2011 Nintendo 3DS
- 2014 Nintendo New 3DS
So yeah they are probably shooting for 3-4 year timeframe, depending on lots of factors obviously. Some reports claiming a $199 or $249 price point brand new which would make a quicker upgrade cycle a lot easier.
Note of Interest: the current new 3DS ships with a PICA200 GPU made by DMP.
PICA200:
65 nm Single Core (max. clock frequency 400 MHz)
pixel performance: 800 Mpixel/s
400 Mpixel/s @100 MHz
1600 Mpixel/s @400 MHz
vertex performance: 15.3 Mpolygon/s at 200 Mhz
40Mtriangle/s @100 MHz
160Mtriangle/s @400 MHz
Anyone know how to translate these figures to something like a 750Ti?
And for what its worth the Wii U is currently using a Radeon 3850ish GPU.
