The last time VIA spoke about Isaiah, they did not give many useful information but only things in the die like architectures. But today a post in Hotwardware have bits of valuable information of the green CPU. VIA finally make sure that the Isaiah CPU to be called Nano. The CPU will be produce with Fujitsu 65nm processing technology, containing twice the numbers of transistors as the VIA C7 CPU while keeping its power efficiency.

Because the amount of transistor has been doubled, and cache upgrade to 8x so Nano actually is not so nano, twice bigger than C7.

The upcoming mass production，VIA will prepare 5 SKUs of Nano, see the chart for details.

Also,VIA have publish some comparison numbers. The comparison is done between Nano, C7 and Celeron M520. Click here to read more of the chip.

Productivity comparison with C7, amazing,but don’t forget C7 is not a good CPU.

It is Per Watt comparison with Celeron M, so it does not means nano performs better than the Intel chip
