PS4 Pro was about 4K, PS5 Pro removes PS5 compromises While the PS4 Pro looked like you’d stuck another deck atop the PS4, the PS5 Pro has managed to maintain pretty much the same size as the existing PS5 while boosting hardware like the GPU and relying a little more on AI to do some heavy lifting to upscale imagery. The PS4 Pro, which introduced 4K HDR gaming to PlayStation gamers for the first time and was arguably a larger leap forward than PS5 to PS5 Pro cost £349.99 / $399 when it arrived in 2016.
