There are three key areas that the company has invested heavily in to use the platform, and one that has placed great emphasis on savings. According to Cerny, developers have been calling for a SONY time to use SSD for their load reduction scenarios, but the company has wanted to continue one step further in this regard.
PlayStation 5 storage: over SSD
PlayStation 5 will protect a PCI-Express 4.0 x4 SSD with a specially designed controller by SONY for the console, which means that it can't convert its SSD storage that it buys separately. This controller has 12 flash channels and is capable of handling transmission rates of up to 5.5 GB / s, And SONY expects the program to provide 100X maximum speed for successful, efficient programming. removes load times completely.
This SSD is 825 GB by default, and will come like this on all PlayStation 5. But don't worry because although this SSD can't be changed or expanded, the console will have another socket to install extended storage and standard SSDs but yes, yesOnly certain products and models are approved by SONY as compatible. Storage can also be expanded with USB hard drives and SSDs, and they said that ps4 games They can work on the PS5 directly from the USB disk, but not the PS5, which should be on the main console's SSD.
The secret to this last plan is that SONY uses its own protocol instead of NVMe which supports six tons of data development (compared to two supported by NVMe). Using this fact, the console has implemented a hardware-accelerated hardware chip, integrated into the main SoC, which, according to Cerny, can, in turn, handle pricing up to 22 GB / s at least.
The processor and drawings, powered by AMD
We've all been expecting more details about the PlayCation 5 SoC, but for some reason the SONY manager wasn't too visibly tasked with revealing anything big. SoC is customized by SONY and AMD as we already know, probably with the process of making AMD & # 39; s 7nm. They did not specify it was monolithic or MCM. They argue that the SoC is divided into three elements: CPU, GPU and I / O complexity.
The processor is based on the AMD Zen 2 x86-64 Microarget and the GPU is RDNA2. We have 8 Zen 2 cores, although the company did not say it will have SMT as it has the Xbox Series X. High performance speed 3.5 GHz, and they claim that the GPU is a completely different story than we'll see on the Xbox Series X. SONY decided that 36 CUs RDNA2 at 2.23 GHz (compare Xbox 588 CUs 1,825 GHz).
So, SONY GPU presents 10.3 TFLOPs vs 12 Microsoft TFLOPs, but the SONY manager said they were not compared because they were built differently. In addition, one of the points where SONY intends to take advantage of Microsoft despite its limited capabilities is due to technology. AMD SmartShift, of course, when a GPU is needed, the system provides CPU (power) resources to the GPU to improve its performance automatically and intelligence, so that the number of TFLOPS is actually higher.
SONY also shines a certain "light" on the use of Ray's tracking Hardware accelerated AMD's adoption of RDNA2. Obviously, each CU has something they've called "Internet Engineers" (Integration Engine) which has the same function as RT Cores in the NVIDIA Turing chart: calculating geometric and geometric coordinates in scenes.
In addition, on the PlayStation 5 ray hardware tracking is also used for audio recordings, ground lighting, shadows, indicators and complete ray tracking.
I / I is complicated
The third key element of the new SONY console is its combination of input and output. This is all I / O processing on the chip, not only in drawings or video, but also in memory and programming. There are I / O processors dedicated to silicon, designed to reduce the I / O performance stack on the processor, or in other words, reduce the processor load and reduce latitude.
There is also a certain amount of SRAM that controls the transmission between different parts of the complex, and which is actually and use AMD SmartShift technology in energy management.
The PlayStation 5 has 16GB of GDDR6 memory, though SONY didn't say speed or bandwidth. Yes, it threw some memory management features into the console, and it looks like the PS5 won't split it as much as the Xbox Series X does, since it probably uses the hUMA model (using a standard program memory and GPU memory team) for the PlayStation 4 that gave the results good.
Positive audio will be the key to PlayStation 5
In the end, a good SONY presentation presentation on the upcoming console is focused on posional audio. Everyone here complained that the presentation went from being too technical, but keep in mind that it was not a presentation to show the console to users but rather to the developers. Basically, they have shown us that the console will have its own audio processor, which will ease the load on the main processor, and use RT to improve the audio position.
We do not yet know the full features of the console technology, and in fact even its appearance, so for now we have to keep on the watch.
In this way, the simple fact that the broadcast presentation – which was apparently filmed – was shown "in public", but was in silhouettes (as if cut out of cardboard pieces) "moved" by the computer. It's very accomplished.
