Last night, Sony finally gave some details on what to expect from the PlayStation 5 from a technical standpoint. as expected, they didn’t reveal any new games or features, but rather on what hardware is in it, and how it will work.
As already stated, the presentation was very technical, but Mark Cerny’s calm and soothing way of explaining it made it very interesting. The main takeaway after all this is as follows:
- x86-64-AMD Ryzen™ “Zen 2”
- 8 Cores / 16 Threads
- Variable frequency, up to 3.5 GHz
- AMD Radeon™ RDNA 2-based graphics engine
- Ray Tracing Acceleration
- Variable frequency, up to 2.23 GHz (10.3 TFLOPS)
- GDDR6 16GB
- 448GB/s Bandwidth
- 5.5GB/s Read Bandwidth (Raw)
PS5 Game Disc
- Ultra HD Blu-ray™, up to 100GB/disc
- Support of 4K 120Hz TVs, 8K TVs, VRR (specified by HDMI ver.2.1)
“Tempest” 3D AudioTech
The interesting takeaway is that the PS5 will have 10.3 teraflops and support Ray Tracing. Though Cerny said it won’t be compulsory to use by the developers. The console will also support backwards compatibility with PS4 titles, and although most should work the company cannot guarantee them all to be available on console launch as some optimisation needs to be done.
But the biggest thing he talked about was the SSD. The console will have a custom 5.5GB/s Read Speed SSD with 825GB installed and Cerny pointed out that this is the best option to balance performance and cost. The PS5 will however support External HDDs, which can load a PS4 game directly, or copy a PS5 game to the SSD for optimal performance. The console also support 3rd party SSDs which can be installed as secondary storage, but only certain drives will be supported.
Finally was the reveal of tempest 3D audio, where more processing power is allocated the audio itself to create better immersion for all, regardless of your sound setup. Tempest will have different audio presets which means everyone will be able to get the best possible audio experience regardless of your personal audio signature.
