Last week, AMD announced its newest series of high end graphics cards, RX Vega, which introduce a number of new technologies on the PC platform. However, it’s since emerged that these technologies could lead to massive performance boosts on the PS4 Pro.
The PS4 Pro includes a chip manufactured by AMD based on its Polaris architecture, which is how the technology is able to come to the platform.
However despite the fact that the PS4 Pro’s upcoming competitor, the Xbox One X, is also built using AMD technology, Microsoft has opted not to include the new functionality.
Rapid Packed Math
In essence, the new technology allows for double the amount of operations to be conducted when less precision is required by switching from full-float to half-float operations.
In other words when 32-bits of precision are not required, the GPU could instead run two 16-bit operations in parallel, thus effectively doubling processing throughput.
For example, a shader may be calculating colors where 32-bits of accuracy is unnecessary and in this instance could drop to 16-bits to save on performance.
One developer we spoke to, Dan Horbury at Mad Fellows Games, described this technology as being like “hyper-threading for …read more
