Just because Intel or some other x86 manufacturer has not made a processor within the same power envelope as ARM does not mean it cannot be done. Also just because ARM hasn't reached the computing performance of x86 also does not mean that it cannot be done. Remember, absence of evidence is not the same as evidence of absence.
Consider that 20 years ago, if you were to tell people that MIPS would be relegated to routers instead of high performance computing, you'd be the laughing stock of everyone around. And yet here we are: MIPS relegated to routers and x86 in the majority of supercomputers.
Because right then and there architectures were in their early inception and most of what made differences were new innovations. Right now, most ways to make architectures fast have already been discovered. As it turns out, more innovation came from RISC in the early days, which gave it a speed advantage. As architectures turned more complex and cost became a bigger factor, x86 took over. PowerPC, for example, hit a wall when it came to performance/watt.
Again, if what you're saying is possible, it'd already be done. Intel has plenty of liquid assets and they'd have made an x86 CPU that can compete with ARM in low power already.
There's no SPARC T4-like Sandy Bridge or vice versa because it's not that simple. The architectures are designed for different purposes. In this case, again, SPARC T4 is made for hugely parallel workloads but compared to something like Sandy Bridge it's left in the dust in single-threaded, which is a very important factor for desktops and laptops.
