I have heard a lot of people saying the CPUs in iPads and iPhones can compare to full fledge x86 CPUs. I will say one thing, ARM (RISC) chips are amazing in terms of performance to power consumption but I think Intel is making much more impressive leaps in their mobile chips.
I have a Dell Venue Pro 8 with a 3740D CPU. Quad Core, 1.8ghz with an Intel HD GPU.
Here is a quick GPGPU benchmark
My iPhone gets less than 1gflops on the LinPac test.. I will have to do more research on the GPU performance but both my Intel HD and CPU combined gets 45Gflops (x64 gets 50gflops) in this test.. and the power consumption is only 2-3 watts. That is impressive. I can imagine the GPU in the iPad air is much much more powerful though.
Now here is where everyone is going say, BUT wait the Apple iPad GPU gets 100's of gflops?! They have much more room on the die to work with given the fact that the GPU in my Dell supports Direct X 11, OpenCL, OpenGL, Direct Compute and so on.. where as the PowerVR does OpenGL...
My Fight here isn't the GPU, it's the CPU.. Just wanted to point that out there. I don't think the Macbook Air will ever get an Atom but a "U" SKU CPU is the perfect match and I son't see Apple Changing to ARM, at all.

IDK maybe I'm more impressed than anyone else..
