PlayStation 6 Backward Compatibility, PS3 Games Emulation Depend on Zen 6 CPU Performance

It appears there have been quite a lot of rumors flying recently concerning the PlayStation 6 and how backward compatibility could be supported via emulation of the PS3 games. It should be acknowledged, though, that all the rumors related to the issue mentioned above were raised on the basis of recent research results proving the point – PlayStation 6 would feature backward compatibility via the emulation of PS3 games.

In particular, assume that you are trying to play PS3 games through your PlayStation 5 console. You already know that backward compatibility does not exist. This is due to the fact that gamers are streaming PlayStation Classics and are not emulating them through their PS5 console. The problem, however, has been going on for a long time now. They prefer emulating PS3 games, and that is what this discussion is all about.

It should be noted that Implicit Conversions Inc., the developer behind the PlayStation Classic ports, was previously reported to be working on PlayStation 3 game emulation.

However, there’s still no real evidence for this. In any case, as discussed, the explanation is the lack of necessary processing capabilities in current hardware. At some point, you can’t emulate PS3 on current devices. Here we see another potential role of the PlayStation 6. The theory put forward suggests that only with the PlayStation 6, which would be powered by the future AMD Zen 6 CPU architecture, will it be possible to deliver adequate performance for Cell-based games.

Indeed, PS3 game emulation is highly CPU-intensive, which brings the Zen 6 CPU to the forefront. Digital Foundry has also participated in this ongoing debate, and the recent test they conducted has heavily influenced public opinion on PlayStation 6 backward compatibility. Digital Foundry apparently conducted PS3-to-PS5 emulation tests using RPCS3, which is currently considered the best PS3 emulator available.

To conduct these experiments, they had to develop a Linux-based loader system, much like those developed by the same team. These test results show that there is definitely a bottleneck here, but it's not in the GPU, as one might assume. It's in the CPU. The PlayStation 5 processor appears to struggle with heavy PS3 game emulation, especially in games that require extensive SPU workloads.

That is why the entire discussion about the Zen 6 CPU is essential for PlayStation 6 backward compatibility. Without any notable CPU improvements, PS3 game emulation will never be stable enough for the entire library. That is why the PlayStation 6 has been suggested as a remedy.

Several PS3 games are quite successful during these tests.

Ridge Racer 7, Resistance: Fall of Man, and Heavenly Sword are all examples of PS3 games that can be made more appealing in the context of higher resolution and better performance by running them through a PlayStation 5. It seems that, in this case, the PS3 game emulation load will not strain the device too much, raising hopes for backward compatibility on a future PlayStation 6.

On the other hand, there are always the difficult PS3 games to emulate. Anyone who has tested games such as GTA IV, Metal Gear Solid 4: Guns of the Patriots, or God of War Ascension knows these games do not perform as well. This is due to the heavy reliance of the aforementioned PS3 games on the SPU for tasks such as open-world simulation and morphological anti-aliasing.

What is important is that increasing resolution does not solve any problems. No matter what you do and whatever resolution you choose, your performance will remain practically unaffected by the change. This indicates that you have nothing to worry about with the GPU bottleneck and everything to worry about with the CPU one, which again confirms the need for PlayStation 6 backward compatibility for PS3 game emulation.

Similarly, other titles, such as Killzone 2, Killzone 3, and the MotorStorm trilogy, can also provide evidence of such dependencies. This time, you should consider situations in which turning off SPU-driven components yields significant performance improvements, thereby once again proving the dependence of PS3 games on the specific hardware architecture. For instance, in Killzone 2, increasing resolution can increase CPU workload because post-processing effects were originally handled by the SPU.

This all ties into the overarching theme being discussed- if Sony desires PlayStation backward compatibility across generations, the PlayStation 6 may be its only opportunity to do so properly.

That would involve PS1, PS2, PS3, and PS4, but it is clear that PS3 game emulation is the biggest problem. Despite the obstacles, there are quite a few optimistic viewpoints on the matter. Among other reasons, PlayStation 6 could succeed is the prospect of backward compatibility, which could be a major promotional factor.

The idea behind this statement is very easy to comprehend; PlayStation 6 would instantly become the ultimate PlayStation if launched as a system that emulates every generation of PS3 and PS2 games, among others. That said, there's even a commercial angle here. Backward compatibility is rarely seen as a major selling point by many companies, but with PS3 game emulation, it takes on more nostalgic tones.

And this would be the moment where PlayStation 6 could really make itself noticed. Even if most users don't look to play old games, the ability to do so would have some serious public relations implications. Another thing to consider is that Sony will probably need to offer major incentives to convince gamers to buy the PlayStation 6.

With each new generation, it's getting harder to find a good reason for gamers to switch, especially as prices go up. Due to backward compatibility, the Zen 6 CPU is perfectly suited to running PS3 game emulation. The idea communicated here is that by marketing the PS6 as the console that finally resolves the backward compatibility problem and allows perfect emulation of PS3 games, it will have a lot going for it.

Although it may not be practical to enable physical discs from all console generations, the mere notion of emulating one console with another via technology is extremely beneficial.

As far as the technical aspect goes, it has been observed that if the Zen 6 processor has enough power, PS6 will be able to eliminate all possible problems associated with PS3 game emulation. Some of these include SPU-based loads, physics calculations, and archaic rendering systems. Through it all, the common thread is that the performance of the Zen 6 CPUs inside the PlayStation 6 makes full PS3 game emulation and backward compatibility a real possibility.

When all of this is summed up, one thing remains clear. In essence, you are looking at a future where PlayStation 6 backward compatibility isn't an additional bonus, but rather the means by which PS3 game emulation could be achieved for the very first time using console hardware. It is safe to say that everything that has been pointed out boils down to performance and the potential of Zen 6 architecture.

Digital Foundry's stance on the matter has also helped affirm that notion. For one, according to Digital Foundry, emulating PS3 games in the future will not only be possible but also require next-generation consoles, such as a PlayStation 6 with a Zen 6 processor. In addition, it can be noted that, in anticipation of future improvements from Sony to enable backward compatibility, the process may not depend solely on third-party applications to emulate games from previous models.

For PlayStation 6, a highly optimized emulation of PS3 games is expected. Preservation of content is also an important factor in this case. The PS3 games are becoming increasingly difficult to play in their original form. If Sony wants to ensure the unification of its platform, PlayStation 6 backward compatibility will be the solution as well.

This point makes it clear that the development of emulation technology in PlayStation 6 will go beyond a side feature and will take a more substantial position. This point brings this discussion to an end. It appears that PlayStation 6 backward compatibility is the only realistic option for emulating PS3 games that people have long waited for.
