Eurogamer put together an article detailing more specific features on the PRO's hardware, it can be read here here.
But what I'm curious about is this:
I thought we were done with bits? Man I don't even know what the fuck a bit is. Can anyone explain this a bit better. I also remember a GAFer saying something a prediction about the PS4 Pro doing this, but he was laughed out. Was he right?
But what I'm curious about is this:
"There's better support of variables such as half-floats. To date, with the AMD architectures, a half-float would take the same internal space as a full 32-bit float. With Polaris, it's possible to place two half-floats side by side in a register, which means if you're willing to mark which variables in a shader program are fine with 16-bits of storage, you can use twice as many. Annotate your shader program, say which variables are 16-bit, then you'll use fewer vector registers."
"One of the features appearing for the first time is the handling of 16-bit variables - it's possible to perform two 16-bit operations at a time instead of one 32-bit operation," he says, confirming what we learned during our visit to VooFoo Studios to check out Mantis Burn Racing. "In other words, at full floats, we have 4.2 teraflops. With half-floats, it's now double that, which is to say, 8.4 teraflops in 16-bit computation. This has the potential to radically increase performance."
