To put this in perspective, when the logic circuits of a CPU want some data, they have to wait a few nanoseconds (billionths of a second) to retrieve it from its cache.... If the CPU were to ask the cloud to calculate something, the answer won't be available for potentially 100ms or more, depending on internet latency - some 100,000 nanoseconds!
The PS4 memory system allocates around 20,000MB/s for the CPU of its total 176,000MB/s. The cloud can provide one twenty-thousandth of the data to the CPU that the PS4's system memory can. You may have an internet connection that's much better than 8mbps of course, but even superfast fibre-optic broadband at 50mbps equates to an anaemic 6MB/s
Beyond the technical considerations of what is and isn't possible due to bandwidth and latency constraints, there are of course economic considerations. Running a server to provide a solo player game is extremely expensive. It makes far more sense to use the servers to run multiplayer games
When you play Battlefield 3 on your Xbox 360, do you have the equivalent power of a dozen Xbox 360s because the server is notionally that powerful? Microsoft's claims seem pretty wishy-washy against such a comparison, and without the explicit clarification that they are literally installing four teraflops of server power for each and every Xbox One bought, the claims of that power target can only be considered bogus PR hand-waving to try and detract from the performance deficit with their rival.
What's obvious at this point is that the concept of cloud computing looks uncertain and unlikely, and Microsoft needs to prove its claims with actual software. Yet based on what we've been told, the firm itself isn't sure of what uses to put it to, while the limitations of latency and bandwidth severely impede the benefits of all that computing power.
Microsoft needs to prove its position with strong ideas and practical demonstrations. Until then, it's perhaps best not to get too carried away with the idea of a super-powered console, and there's very little evidence that Sony needs to be worried about its PS4 specs advantage being comprehensively wiped out by "the power of the cloud".
