'Of course, we already knew that the Pro graphics core implements a range of new instructions - it was part of the initial leak - but we didn't really know exactly what they could actually do. As we understand it, with the new enhancements, it's possible to complete two 16-bit floating point operations in the time taken to complete one on the base PS4 hardware. The end result from the new Radeon technology is the additional throughput required to making Mantis Burn Racing hit its 4K performance target, though significant shader optimisation was required on the part of the developer.
In short, there's more to PS4 Pro's enhancements than teraflop comparisons suggest - and we understand that there are more 'secret sauce' features still to be revealed. At the PlayStation Meeting, Sony staff told me that the enhancements made to the core hardware go beyond the checkerboard upscaling technology, and the new instructions certainly support Mark Cerny's assertion that the PS4 Pro possesses graphics features not found in AMD's current Polaris line of GPUs. Interesting stuff, and we look forward to learning more.'
