The z-60 is just a refresh of the c-50/z-01 which was a dual core 1ghz brazos. The acer w500 used it and so did the msi winpad w110 or something. They both got 4-6 hours depending on what your doing.
The z-60 is basicly 4.5w while the z-01 was 5.9w. you still need the second chip for the sata/usb and other stuff . The clover trail cpus have the gpu and all the other functionality on the same chip and use less than 2w .
Amd had a real chance and all they really had to do was drop brazos to 32nm from 40nm. They most likely could have gotten the c-50 to 1.5 to 1.8 ghz and upped the gpu speeds while lowering the tdp and it would have been an amazing cpu
AMD always end up late to the party, even if it's their party (e.g. Fusion).
They are going up against 22nm Intel processors and 28nm Android tablets with ... 40nm Bobcat, like almost 2 years ago. Meanwhile they can't sell Llano or Bulldozer and the company is focused on Piledriver.
Trinity aside, it's like AMD are constantly targeting the wrong segments of the market with their processors. A fast dual core tablet processor would be like golddust, but AMD are stuck with dual core Brazos on 40nm, a quad core Jaguar on 28nm which isn't actually here and an 8 core monster chip which sucks for consumer workloads. Even a 28nm shrink of the ancient Brazos would give them a chance to do something in the Windows 8 market, but as things stand they're nowhere to be seen.
Acer has already announced a successor to its W700 tablet based on 7W SDP Ivy Bridge with a 20% thinner and 20% lighter chassis
