PS4′s GPU advantage over Xbox One isn’t as game-changing as you think it is, special benchmarks show
Hardware enthusiasts run graphics benchmarks on next-generation console-equivalent PC hardware to find out if the PlayStation 4′s better specifications make a noticeable difference on gameplay.
As discussed in detail in our article on PS4 vs. Xbox One GPU Performance, Sony’s PlayStation 4 has a 50% advantage in graphical performance over than Microsoft’s Xbox One, thanks to increased number of shader cores and a wider memory bandwidth.
But how much would that affect graphics on PS4 vs. Xbox One?
Digital Foundry at EuroGamer set out to find the answer to that question. They used AMD’s Radeon HD 7790 GPU in one system build as an Xbox One equivalent, and a Radeon HD 7870 for an other to mimic the PS4. Both GPUs have a roughly 50% difference in graphics performance, so it’s a fair comparison.
Understanding that this is a graphics-focused experiment, Digital Foundry used a Core-i7 3770K overclocked to 4.3GHz, and 16GB of DDR3 RAM clocked at 1600MHz to ensure CPU and RAM doesn’t become the bottleneck.
The results are a tad surprising. A 50% increase in raw graphical performance only gave the PS4 equivalent system around a 25% boost in framerate at the same graphical settings and resolution. The reason behind this is that increasing the number of cores in a GPU doesn’t result in a linearly increased performance. Core clock-speed and memory speed matters as well.
All in all, don’t expect the PlayStation 4 to have a noticeable advantage over Xbox One in graphics right out of the gate. Cross-platform games will look the same on both systems for years to come, and exclusives won’t truly take advantage of the extra 50% until after the two-three years it takes for developers to understand new console system architecture.
