We pay extra for 150Mbps 'Extreme' internet from our local cable company. Of course, if you are connecting to the internet via a cable TV hookup, you won't get those speeds. Anandtech tested some 802.11ac devices back in July achieving real-world throughput as high as 541Mbps. The rated throughput of 'high-end' 802.11ac products should be around 910Mbps compared to 320Mbps for 'max' 802.11n products. This speed increase also affects the Fusion Drive which uses a flash module fused with an HDD - as long as you don't overflow the flash module. The same or similar jump in speed will be available in the 2013 iMac versus the 2012 iMac. Compare that to the 2012 MacBook Air's flash storage we clocked at 484MB/s. When we benchmarked it the large transfer speed was 794MB/s. The same flash storage is used in the 2013 MacBook Air. The flash storage is at least 50% faster. It will be interesting to see how the two compare running GPU intensive apps like OctaneRender, DaVinci Resolve, Diablo III, etc. We recently tested a 'custom' GTX 780 with 3GB of GDDR5 in the 2010 Mac Pro. If you order the top 27' model of the 2013 iMac, you can get the optional NVIDIA GeForce GTX 780M with 4GB of GDDR5. The top GPU is faster with more video memory than ever. However there is more to this update than just CPU.
