Unmatched transfer speed for a console
For starters, Mark Ceny spent a lot of time on switching to SSD storage and the huge performance boost that results. Sony has designed a homemade SSD controller with a 12-channel interface for this. The company promises a transfer speed of more than 5 GB / s with an almost instant loading time. As a comparison guide, it takes 20 seconds for the PS4 to load 1 GB of data where the PlayStation 5 will require less than a second to load 2 GB of data: only 0.27 seconds to be more precise.

The SSD will also allow more efficient use of RAM memory. The loading times will be all the more reduced as there will be no need to load a lot of data into the RAM. The system can do this from the SSD if necessary.
PlayStation 5: 10.28 TFLOPS AMD RDNA 2 GPU
We already knew that Sony will be relying on a custom AMD APU again. On the one hand, the PS5 has an 8-core Zen 2 CPU clocked at 3.5 GHz. The GPU as far as it is concerned is based on the RDNA 2 architecture which is compatible with ray tracing for an ultra-realistic simulation of light and shadow effects. The graphics chip consists of 36 computing units at 2.23 GHz (variable frequency) and will be able to deliver a gross computing power of 10.28 TFLOPs, almost 2 less than the Xbox Series X and its 12 TFLOPS.

The whole is supported by a 16 GB GDDR6 RAM memory with a bandwidth of 448 GB / s. Finally, the PS5 has a free slot to accommodate an NVMe SSD to supplement the standard storage capacity of 1 TB. Sony is also announcing support for external hard drives via a USB port. The PlayStation 5 is also equipped with a 4K Blu-ray player to accommodate physical games.
Sony had already announced a lot of details on the PS5 that it has just confirmed. The console will be technically capable of handling definitions up to 8K and will allow in particular to shoot games in 4K at 120 fps. There is also talk of a 3D audio system for immersive sound, which allows players to fully commune with their games. Finally, backward compatibility with the PS4 is also part of the game, as is a low-consumption mode that will save energy.
A revolutionary 3D audio engine
Let us dwell a little on the sound part. With the processing power of the PS5, Sony has invested in a new engine for 3D audio called Tempest Engin. The latter is capable of emulating hundreds of sound sources to produce a very realistic suround effect. The player will feel like the sound is coming from hundreds of different directions.
For example, when it rains in a game, you will feel like you can hear the sound of water tasting in all directions, creating even more impressive immersion. For comparison, the PlayStation VR, which is designed for the immersive experience of virtual reality games, emulates only 50 different audio sources.
