The graphics processor (GPU) in the PS4 Pro – that’s the bit that generates the 3D graphics in games – is just over twice as powerful as that in the PS4. Sony’s also upgraded the processor, which handles things like physics and artificial intelligence in games.
Sony claims the new PS4 Pro can run at 4.2 teraflops, compared to the 1.84 teraflops of the original PS4 – teraflops is a simple measure of computer performance, a bit like horsepower in cars. We’ll get onto how that power is used a little later.
In addition, while the PS4 Pro has the same amount of memory as the original PS4 – 8GB GDDR5 – it runs at a higher speed to improve performance. The PS4 Pro also has an extra 1GB of memory for non-gaming applications like Netflix. This means they won’t waste space games can use and means you can switch between apps faster.
