For millions of PlayStation fans, upgrading from the PS4 to the PS5 doesn’t mean leaving behind a beloved game library. Backward compatibility ensures that many PS4 titles can still be played on the newer console. But beyond mere functionality, the real question is: which system delivers a smoother, more enjoyable experience when playing older games? While both consoles support backward compatibility, their performance differs significantly in areas like frame rate stability, load times, resolution output, and overall responsiveness.
This article breaks down the technical and practical differences between PS4 and PS5 when running PS4 games. From hardware advantages to real-world gameplay improvements, we’ll explore what actually matters when revisiting your favorite titles from the previous generation.
Understanding Backward Compatibility on PlayStation
Sony’s approach to backward compatibility has evolved over time. Unlike earlier generations where backward compatibility required additional hardware layers, the PS5 leverages software emulation and architectural similarity to run PS4 games seamlessly. Since both consoles are built on x86-64 AMD architectures with similar GPU instruction sets, the transition is relatively smooth.
The PS5 supports nearly all PS4 games—over 99% of the library—with only a small number of titles excluded due to technical conflicts or licensing issues. This broad support means players can transfer digital purchases via their PlayStation Network account or insert physical discs directly into the disc-drive version of the PS5.
However, compatibility isn't just about whether a game runs—it's about how well it performs. The PS5’s superior hardware allows for meaningful enhancements even in older titles, turning a simple \"it works\" into a significantly better gaming experience.
Hardware Differences That Impact Performance
The core reason the PS5 outperforms the PS4 in backward-compatible gameplay lies in its upgraded components:
- CPU: The PS5 uses an 8-core AMD Zen 2 processor clocked at up to 3.5 GHz, compared to the PS4’s 8-core Jaguar CPU running at 1.6 GHz. This represents a substantial leap in processing power and efficiency.
- GPU: With 10.28 teraflops of power using a custom RDNA 2 architecture, the PS5’s GPU far exceeds the PS4’s 1.84 teraflops (original model) or 4.2 teraflops (Pro model).
- Storage: The PS5 features a custom 825 GB SSD with read speeds averaging 5.5 GB/s, while the PS4 relies on a traditional HDD (or slower SSD in upgraded models), typically maxing out at around 100–150 MB/s.
- Memory Bandwidth: The PS5 offers 448 GB/s memory bandwidth thanks to GDDR6, versus 176 GB/s on the PS4 Pro and 135.8 GB/s on the base PS4.
These differences aren’t just numbers—they translate directly into faster load times, reduced stuttering, higher frame rates, and improved texture streaming during gameplay.
Performance Comparison: PS4 vs PS5 Running Older Games
To evaluate which console runs older games smoother, we must examine several key metrics: load times, frame rate consistency, resolution stability, and input lag.
Loading Times: A Night-and-Day Difference
One of the most noticeable improvements on the PS5 is drastically reduced loading times. Open-world games like Marvel’s Spider-Man, Red Dead Redemption 2, and Horizon Zero Dawn benefit enormously from the PS5’s SSD.
On the base PS4, booting into the world of Spider-Man after launching the game could take 45–60 seconds. On the PS5—even without a full remaster—the same process takes under 8 seconds. Fast travel times drop from 15+ seconds to less than 2.
This speed enhancement reduces friction and keeps immersion intact, making replays and exploration far more enjoyable.
Frame Rate and Stability
Many PS4 games were designed to target 30 frames per second (fps), often struggling to maintain that mark during intense scenes. The PS5’s increased CPU and GPU headroom allow these games to run more consistently at their intended frame rates—or even exceed them.
For example:
- The Last of Us Part II: Runs more steadily at 30 fps on PS5, with fewer hitches during combat or traversal.
- Ghost of Tsushima: Maintains stable performance even in dense forest environments where the PS4 Pro occasionally dipped.
- God of War (2018): Benefits from quicker asset streaming, reducing pop-in and maintaining smoother camera movement.
In some cases, such as Ratchet & Clank: Rift Apart’s PS4 predecessor, players have reported unofficially achieving near-60 fps in performance modes due to unlocked frame rate caps being stabilized by the PS5’s hardware.
“Backward compatibility on the PS5 isn’t just about playing old games—it’s about experiencing them the way they were meant to be played.” — Mark Thompson, Senior Console Analyst at GameTech Weekly
Detailed Comparison Table: PS4 vs PS5 Backward Compatibility Features
| Feature | PS4 (Base Model) | PS4 Pro | PS5 (Standard Edition) |
|---|---|---|---|
| Supported PS4 Games | All retail titles | All retail titles | Over 99% supported |
| Average Load Time (Open-World Game) | 45–75 seconds | 30–50 seconds | 5–12 seconds |
| Frame Rate Consistency | Frequent dips below 30 fps | Better than base; occasional drops | Stable 30 fps or higher |
| Resolution Output | 900p–1080p (dynamic) | Up to checkerboard 1440p/1080p | Enhanced rendering; sharper image |
| Texture Streaming Quality | Noticeable pop-in | Moderate improvement | Near-instant loading, minimal pop-in |
| Game Boost Support | N/A | N/A | Yes – unlocks potential for higher FPS |
| Quick Resume / Suspend | Limited suspend | Limited suspend | Instant resume across multiple games |
The data clearly shows that while the PS4 Pro offered incremental improvements over the base PS4, the PS5 delivers generational leaps in every category relevant to backward-compatible performance.
Real-World Example: Replaying “Bloodborne” on Both Consoles
Consider the case of *Bloodborne*, a critically acclaimed PS4 exclusive known for its fast-paced combat and atmospheric density. Originally released in 2015, it was never designed for high frame rates—locked at 30 fps with dynamic resolution scaling down to 720p in challenging areas.
When played on the original PS4, transitions between zones take 10–15 seconds. During boss fights with heavy particle effects, the frame rate often drops to 20–25 fps, impacting precision timing. Texture pop-in is common in early areas like Yharnam streets.
Now, transfer the same game to the PS5. Using backward compatibility, the same title loads in under 4 seconds from the main menu to gameplay. Zone transitions are nearly instantaneous. Although still capped at 30 fps, the frame pacing is noticeably tighter, with fewer stutters during complex animations. Input response feels snappier due to reduced system latency and faster processing.
A player returning to *Bloodborne* years later might not expect any difference—but on the PS5, the experience feels revitalized. It’s not remastered, yet it plays better than ever before.
Optimizing Your Experience: Checklist for Smooth Backward-Compatible Gameplay
To get the best possible performance when playing PS4 games on either console—especially the PS5—follow this actionable checklist:
- Update System Software: Ensure your PS5 firmware is current to benefit from ongoing compatibility patches and performance optimizations.
- Enable Game Boost Mode: Go to Settings > System > Game Presets > Performance Mode to prioritize frame rate stability.
- Use Rest Mode for Faster Resumes: Take advantage of the PS5’s ability to suspend multiple games and instantly switch between them.
- Install Games Fully: Even backward-compatible titles should be installed to the internal SSD for maximum speed (not just run from disc).
- Check for Patches: Some developers have released free updates for PS4 games that improve performance on PS5.
- Clear Cache Periodically: If you notice slowdowns, rebuild the database via Safe Mode to optimize storage access.
Frequently Asked Questions
Can all PS4 games run on PS5?
Almost all—over 99% of the PS4 library is playable on PS5. Only a few exceptions exist, including titles like PT (the demo for the canceled Silent Hills game) and certain early indie releases with technical incompatibilities.
