PS5 Pro GPU Deep Dive: Mark Cerny Reveals RDNA 2.x Architecture and 16.7 TFLOPs Performance

In a surprise move, Sony released a 37-minute technical deep dive with PlayStation console architect Mark Cerny, shedding light on the PS5 Pro’s GPU architecture and performance. The video clarifies much of the speculation surrounding the console’s capabilities, particularly its much-debated TFLOPs rating.

Cerny revealed that the PS5 Pro’s GPU utilizes a custom architecture built upon AMD’s RDNA technology, blending elements of both RDNA 2 and RDNA 3. This hybrid approach, dubbed RDNA 2.x, allows for backward compatibility with existing PS5 games while simultaneously delivering performance enhancements. The incorporation of RDNA 3 features, particularly in primitive processing, contributes significantly to the enhanced graphical capabilities.

One key point of clarification was the PS5 Pro’s TFLOP rating. While various sources cited figures as high as 33 TFLOPs, Cerny confirmed the actual figure to be 16.7 TFLOPs. This represents a substantial 67% increase over the base PS5’s performance. The 33 TFLOPs number stemmed from a misunderstanding; the doubling of TFLOPs seen in the jump from RDNA 2 to RDNA 3 was incorrectly applied. This would necessitate separate game versions for PS5 and PS5 Pro, a burden Sony wants to avoid for developers.

Cerny detailed the calculation, stating that the PS5 Pro’s 30 Work Group Processors (a 67% increase over the base PS5) directly correlate to the 67% performance uplift. Using a typical operating frequency of 2.17 GHz, the calculation accurately arrives at the 16.7 TFLOPs figure. This approach ensures seamless backward compatibility and simplifies game development, prioritizing ease of development over maximizing raw TFLOP numbers.

This in-depth explanation addresses much of the confusion surrounding the PS5 Pro’s specs. The focus on backward compatibility, efficient development, and real-world performance improvements highlights Sony’s strategic approach to the console’s architecture. The release of this technical video shows a commitment to transparency and engaging directly with its developers and consumers. This approach is crucial in building community trust, enhancing the console’s value proposition, and managing expectations among the gaming community. The detailed technical information not only clears up misconceptions but also further establishes the PS5 Pro as a powerful addition to the PlayStation ecosystem. The strategic balance between raw performance and developer-friendly design positions Sony favorably within the increasingly competitive gaming console market. Expect further analysis and discussion of the implications of this architecture in the coming weeks as developers explore the PS5 Pro’s capabilities.

The PS5 Pro represents a powerful step forward, building on the success of its predecessor while focusing on improvements to enhance gaming experiences for both developers and players. The strategic blend of AMD’s RDNA 2 and 3 architectures, combined with Sony’s commitment to backward compatibility, ensures a compelling offering in the competitive market of next-generation consoles.
