Sony today unveiled the first technical capabilities of the new PlayStation 5 – be fast, quiet, and about audio and developers.
Two days ago, the XBOX Series X was introduced (summarized in the next news), and even SONY doesn't delay, even when the coronavirus rages outside. The preliminary date of the show is valid for the end of this year, but due to developments, we will see.
PlayStation 5 will be powered by AMD Ryzen's 2nd generation 8-core and a brand new RDNA2 graphics card architecture, which will be introduced by AMD for the desktop market later this year. What's new is that the graphics card will have dedicated units for Ray-Tracing, just as NVIDIA's current RTX generation has. Technologically, it will differ significantly from the current PS4. The maximum frequency of 36CU cores, i. The 2304 processor shaders will be 2230 MHz, but the entire SoC will use variable frequency timing. The processor will tick at ~ 3.5 GHz. Sony points out that the fluctuation will be a maximum of a few%, depending on TDP – the radiated heat. They did not want the console to be particularly loud when playing. During the design, they found that it was better for the graphics core to have fewer active units and mainly to use a fast clock. For comparison, the XBOX One Series X is 20% more efficient on paper. It uses up to 52 CU units and the maximum clock is 1825 MHz, which means 12 TFLOPS (10.3 TFLOPS will have PS5). We'll see how in practice the PS5 catches up with its opponent, because it's internally designed completely differently. The XBOX One Series X is closer to computers, with the PS5 being a hybrid. An important but not very highlighted novelty is AMD SmartShift, which is actually free computing power of the main processor. In case of low load or incomplete use, it can also act as a powerful graphic coprocessor! It should add a few frames per second to help maintain a stable frame rate.

Of particular interest is memory. The internal memory will be only 16GB GDDR6 shared for CPU and GPU (ie VRAM), while deeply connected to 825GB PCIex 4.0 based SSD. 825GB SSD also serves a kind of fast cache. PlayStation 5 requires a throughput of 5.5 GB / sec. The SSD can be upgraded with certified PCIex 4.0 NVMe M2 with the same throughput. That is not yet known as they are undergoing certification, but it has been mentioned that they must be certified – some controllers become very hot or require passive cooling. The 825GB SSD controller is custom-made and has 12 channels. Since it will be a highly integrated component, the question is lifetime. It can be assumed on the basis of transcripts around 5 years, SONY of course called it “the life of the console”. The advantage will of course be the fast loading of titles, and the possibility to create large worlds with big data.
The latest important innovation is support for 3D AUDIA – surround sound. Sony counts on deployment for surround bar, stereo TV speakers and headphones. The easiest implementation is with headphones, where there are 7.1 models already on the market, certification will be needed again. Interesting is the upcoming support of virtual audio for stereo speakers in TVs, SONY has been working on it for two years, and it will probably be necessary implementation on the side of the TV manufacturer. SONY emphasized that audio will improve over the life of the console, as this requires a complex process of development and communication with game developers.
Backward compatibility with the current generation is also guaranteed …
We have something to look forward to.
