During the year, various insiders treated us with information about the following Playstation and Xbox. One of the biggest leaks concerned disclosing the characteristics of the CPU and memory, published in August by the user under the nickname Snooper. He found in the 3DMark database the test results of the chip, codenamed Oberon, released by AMD and supposedly intended for the PlayStation 5.
Should you trust this leak? The big question. But Digital Foundry staff said the information was genuine.
As Richard Leadbetter notes, GitHub was the source of the information. Presumably, one of AMD employees used the service to store the test results of new processors. Given that the leak occurred in the summer, it turns out that the tests were carried out in the first half of 2019.
Based on the data obtained, Digital Foundry specialists tried to build an analogy from the available on the market computer hardware based on Navi. They allocated two chips – Oberon (as previously mentioned, supposedly for the PlayStation 5) and Arden (presumably, the Xbox Series X processor).
Graphics subsystem – teraflops number and performance
According to an AMD leak, the PS5 GPU will be able to boast 36 accessible computing units operating at a frequency of 2.0 GHz. All this will provide performance at the level of 9.2 teraflops.
It should be clarified that these figures can in no way be compared with those of the current generation – the performance of the next generation, measured in teraflops, is much more effective than its current equivalent. In addition, the number of teraflops does not take into account other aspects of iron, such as the built-in SSD, ray tracing technology and other similar functions (in short, it cannot be said that “PS5 is 3 teraflops more powerful than Xbox One X.” Navi architecture is much more efficient than the current and next-generation consoles are much more than just the number of teraflops).
The Arden processor will have the following characteristics: 56 computing units and a frequency of 1.7 GHz. The graphics power of the Xbox Series X is thus 12.2 teraflops.
RAM – GDDR6 confirmed
The leak confirms that the PS5 will be installed expensive RAM standard GDDR6. It will work very quickly and have a throughput of about 448 Gb / s (according to some sources, 512 Gb / s). As for the volume, the leak points to 16 GB – the same amount is supposed to be in the Xbox Series X.
The combination of super-fast GDDR6 RAM and low-level access to SSDs will allow you to create huge long-lasting worlds, similar to what you can see in Cyberpunk 2077.
For comparison, in the Xbox Series X, according to the leak, GDDR6 memory with a bandwidth of 560 Gb / s will be built in.
Backward Compatibility – Iron-Level Emulation Confirmed
The leak indicated three GPU modes between which the system could switch. The Gonzalo chip has various frequency options: 2 GHz, 0.8 GHz and 0.911 GHz. The first is referred to in the leak as Gen2, and the other two modes, Gen1 and Gen0, correspond to the frequencies of the PlayStation 4 and PlayStation 4 Pro. It turns out the PS5 will support hardware-level emulation. No long waiting for patches – just inserted a disc from the PS4 or downloaded any project and play.
As for the “improvements” of the existing PS4 games that the PS5 can provide in one way or another (resolution, frame rate), nothing is known about them so far.
In addition, Digital Foundry staff noticed the lack of mention of ray tracing in Oberon tests. However, this does not mean that the chip for the PS5 does not support this technology, perhaps AMD simply did not test it..
Comparison of characteristics in a visual form:
Oberon (supposedly PlayStation 5)
- Central processor: 8 core, Zen 2 architecture, support for simultaneous multithreading, frequency unknown.
- Graphics subsystem: 36 computing units, Navi architecture, frequency 2000 MHz.
- Memory: 16GB, GDDR6, bandwidth of 448 GB / s or 512 GB / s.
- Productivity: 9.2 teraflops.
Arden (presumably the Xbox Series X)
- Central processor: 8 core, Zen 2 architecture, support for simultaneous multithreading, frequency unknown.
- Graphics subsystem: 56 computing units, Navi architecture, frequency 1700 MHz.
- Memory: 16GB, GDDR6, bandwidth 560 GB / s.
- Productivity: 12.2 teraflops.
Despite the comparative characteristics and a noticeable difference, in particular, in terms of teraflops, Digital Foundry employees find it difficult to answer which console is more powerful. Once again, we recall that the number of teraflops does not take into account other aspects of iron and in no case is equal to the overall system performance.
The conditions under which the old tests were conducted are also unknown.
But if we assume that the PlayStation 5 will have current characteristics (16 gigabytes of GDDR6 and 1 terabyte SSD), then the future console has every chance to enter the market with a price of around $ 399.
Earlier, Kotaku sources claimed that the PlayStation 5 and Xbox Series X will have almost the same characteristics.
