With the launch of AMD RX Vega’s high end series of graphics cards scheduled at the coming Monday, and its highly possible success of RX Vega, another matter just surfaced. RX Vega’a Rapid Packed Math can seriously show in increase in PS4’s performance, which will close the performance gap between PS4 and Xbox One X.
But first things first! What really is Rapid Packed Math.
RPM (Rapid Packed Math) features allows any GPU to perform two half-float operations (FP16) instead of performing a single long full-float operations (FP32). This seemingly simple process significantly improves the graphics of the GPU.
What AMD has to say about RPM.
AMD said the following about the RPM.
“Next-Gen Compute Units (NCUs) provide super-charged pathways for doubling processing throughput when using 16-bit data types.1 In cases where a full 32 bits of precision is not necessary to obtain the desired result, they can pack twice as much data into each register and use it to execute two parallel operations. This is ideal for a wide range of computationally intensive applications including image/video processing, ray tracing, artificial intelligence, and game rendering.”
AMD conducted a test on one of its graphics cards, have a look at it below.
The effect of RPM is quite evident. AMD made a video and explained their take on RPM in the video below. The New Colossus and Far Cry 5, two of the most anticipated and awaited first-person shooters which is due in the upcoming months, will support Rapid Packed Math.
Let’s move on to PlayStation 4 pro.
System Architect Mark Cerny admitted in his statement stated below that PS4 Pro will be making use of RPM. He quoted that,
“A few AMD roadmap features are appearing for the first time in PS4 Pro. 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. 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.”
Other game developer agreed with this fact.
How is Microsoft reacting to all the matter of RPM?
Microsoft didn’t seem to be bothered by RPM, they were quite confident that their Xbox One X will be ahead of PS4 Pro due to its extra memory and GPU. And secondly they stated that most third party developers won’t be putting much time into RPM’s research and they would simply skip putting the option of RPM in their games.
Who knows? What the future holds!
If more games support RPM then PS4 pro can go ahead of Xbox One X in terms of performance. And when it comes to gaming, performance is the questions of survival. The fate of both gaming consoles falls on the shoulders of developers.
