What your missing is that with the lengths Microsoft have gone to improving computing efficiency that the CPU is now twice as powerful as the X1 CPU. Don't only look at the 31% clock increase. There is much more to it then that. You should read the articles over at Digital Foundry. For instance the fact that DX12 on the Scorpio is now a hardware feature (not even on PC is DX12 a hardware level feature) makes massive improvement in how much less CPU resources are tasked. When you go from 1000 commands to 9 or 10 that is a massive amount of CPU overhead gone. Like I said, with this console it's more then just the "specs".
This isn't quite what you think it is. Titles received up to a 50% DX12 driver overhead reduction, and it was part what they did a long while back, and its in both the xbox and xbox s. Depending on the game (and the driver optimisation), people were able to see an up to 15% improvement in performance.
It does not mean the CPU is 50% more powerful because they made the direct x in the hardware. They changed reprogrammed how they were using the hardware from a driver level, and overhead was greatly reduced. That is all.
Depending on the price, I'll buy one. But I'm not paying another 500, which is what I expect the price to be, probably going to wait until it comes down to 400.
Two things worry me - 1 is will it play all the existing xbox games (considering it is a change of architecture), and 2, how long before Sony announce the PS5.
