Merrifeld is a 22nm Atom SOC. There are samples and benchmarks
Intel's mobile/Atom 22nm SOC in market in late 2013 is 2 years behind Foundry/ARM 28 nm shipping now (foundry 28nm and Intel's SOC 22nm has about same transistor density making it a reasonable point of comparison).
Intel's silicon group has been the biggest hindrance to getting into mobile market.
Intel's move to finFET has also been a major setback to getting into mobile market. Intel finFET SOC have been talked about for 2 years but are still another 1.5 years away from chips on market. Intel's finFET SOC is late since large delay in moving all the design IP due to issues with transistor matching, analog, RF , and I/O are all not attractive on a bulk finFET SOC vs since at total chip system level intel's 22nm finFET has negligible advantage over foundry 28nm planar transistor.
'foundry 28nm and Intel's SOC 22nm has about same transistor density making it a reasonable point of comparison'
No, Intel's 22nm has superior transistor drive/leakage/density advantages over foundry's 28nm. Why do you think all the foundries are scrambling to do finfet technology as well ? It is to catch up to Intel.
'since at total chip system level intel's 22nm finFET has negligible advantage over foundry 28nm planar transistor.'
Intel's high performance 22nm process will enable 7W Ivy Bridges, how much better do you think the actual 22nm LP SoC process will be ? You are just making up FUD to support your Short position.
