The new slim model packs all of the hardware from the original model into a smaller form, resulting in a decrease in size of about 30%. Of course, to squeeze into a smaller shell, there often have to be sacrifices, but the only loss here is the optical audio port — all other ports and components, including the two USB 3.0 ports, Ethernet port, HDMI and AUX ports, remain.
When Sony says the PS4 Slim is the same as the original PS4, just in a smaller package, it isn’t kidding. The same GPU, CPU, and RAM that power the original PS4 are in the PS4 Slim, and both consoles will run games at the same proficiency — you won’t see any visual or technical enhancements to your games by playing them on one over the other.
When it comes to storage space, the PS4 and PS4 Slim are identical. The original PS4 had a 500GB model, which the Slim matched when it launched, but both systems moved to a 1TB drive shortly after. One of the key features of the original PS4 was its removable hard drive. With no more than a couple of tools and about 20 minutes, you could easily upgrade your PS4’s hard drive. That functionality is still present on the Slim, and it’s even easier to do.
