Yes it can, but he was asking if it would be 2.23 GHZ all the time, which it isn't, it's pretty clear what a variable frequency means. The GitHub leak was correct apart from that, so it's easy to assume that the clock speed is a late change to counter the XSX 12.155 TFLOPS GPU.
This doesn't make sense. The system they have in place is pretty clever. Its not just going to be thrown in at the last minute. Most people on here were saying they couldnt even hit 2ghz and they have a system which effectively goes beyond that. This is a well thought out system. The differences vs the XSX is that they have placed greater emphasis on SSD and are probably going to be better on price.
