Emulating PlayStation 3 games on PC has come a long way thanks to RPCS3, the leading PS3 emulator. What once seemed impossible is now a reality, with thousands of titles running smoothly if you have the right hardware.
The RPCS3 CPU Tier List ranks processors by emulation performance. Modern Ryzen and Intel CPUs dominate, while older AMD pre-Ryzen and Intel chips with under four cores fall into F-Tier due to poor compatibility.
This article breaks down the latest RPCS3 CPU Tier List for 2025, highlights the best CPUs for different budgets, and explains the factors that make some chips perform better than others. If you’re planning to build or upgrade your PC for emulation, this guide will help you make the right choice.
What is RPCS3 and Why CPU Performance Matters?
RPCS3 is an open-source PlayStation 3 emulator that allows PC gamers to play PS3 games with improved performance, higher resolutions, and modding options. But PS3 emulation is extremely demanding because of the console’s unique Cell processor.
Unlike typical PC games that lean heavily on the GPU, RPCS3 needs raw CPU power to translate the complex instructions of the Cell architecture into something a PC can understand.
This means higher clock speeds, strong single-core performance, modern instruction sets like AVX-512, and enough threads to handle the load all play a role in performance.
How We Ranked CPUs in This RPCS3 Tier List
The tier list is based on recent benchmarks, community testing, and official RPCS3 team recommendations. Processors are ranked by their ability to run demanding titles at stable frame rates with recommended accuracy settings.
The main factors include:
- Single-core speed – Higher clock speeds translate into better emulation.
- Instruction set support (AVX-512) – Essential for boosting RPCS3 performance in many games.
- Core and thread count – Helps with multitasking, but not as important as single-core power.
- Thermal stability – Sustained performance without throttling.
It’s also worth noting that performance can vary depending on the game. Some lighter titles may run fine on mid-range CPUs, while heavy games like Demon’s Souls or Uncharted 3 push processors to their limits.

RPCS3 CPU Tier List 2025 (Full Breakdown)
Here’s where today’s CPUs stand in the RPCS3 performance hierarchy.
S-Tier – Best of the Best CPUs
If you want flawless performance in nearly all PS3 games, this is the category to aim for.
- Intel Core i9-14900K / i9-13900K
- AMD Ryzen 9-7950X / Ryzen 7-9800X3D
These chips combine high clock speeds with massive core counts and AVX-512 support. They deliver stable 60 FPS or higher in demanding titles and are future-proof for years. The 9800X3D and 7950X also benefit from AMD’s massive cache design, which helps in emulation workloads.
A-Tier – High Performance CPUs
A step below S-tier but still excellent for most users.
- Intel i7-14700K / i5-13600K
- AMD Ryzen 7-9700X / Ryzen 7-7800X3D
These CPUs handle nearly all games smoothly, though the most demanding titles may show occasional drops. The i5-13600K in particular offers incredible value for its price and is one of the most recommended options for RPCS3 in 2025.
B-Tier – Mid-Range CPUs
Solid choices for gamers who don’t mind a few compromises.
- Intel i5-13400 / i5-12400
- AMD Ryzen 5-7600X / Ryzen 5-5600X
These CPUs are fine for lighter PS3 games and many 2D titles, but performance can dip in graphically intense or CPU-heavy games. Still, for budget-conscious players, these processors get the job done.
C-Tier – Entry Level / Budget CPUs
These are only recommended if you already own them.
- Older Intel 10th/11th Gen i5 and i7 CPUs
- AMD Ryzen 3000 series
They can run some PS3 games, but performance is inconsistent. Games that rely heavily on the Cell’s SPUs will struggle, and stuttering is common.
D / F-Tier – Not Recommended
Older CPUs without modern instruction sets, weak single-thread performance, or low clock speeds fall here. They are not suited for RPCS3, and upgrading is the only real solution.
Best Value CPUs for RPCS3 in 2025
While S-tier processors dominate in raw performance, not everyone needs to spend that much money. Here are the best value picks:
- Budget choice: Intel i5-13400 – Affordable and surprisingly capable for less demanding titles.
- Mid-range choice: Intel i5-13600K – Strikes the perfect balance of performance and price.
- High-end choice: AMD Ryzen 7-7800X3D – Excellent for both gaming and emulation with a reasonable price tag.

Key Factors Affecting RPCS3 CPU Performance
AVX-512 Support – Why It Matters
AVX-512 is a powerful instruction set that significantly boosts emulation. CPUs without it will always lag behind in RPCS3, regardless of core count or base speed.
Single-Core vs Multi-Core Balance
While multi-core CPUs are great for modern games, RPCS3 benefits far more from strong single-thread performance. That’s why chips with high boost clocks often outperform CPUs with more cores but weaker per-core strength.
Cooling & Thermal Throttling
Even the best CPU won’t perform well if it overheats. Good cooling ensures stable clock speeds, which directly impacts emulation smoothness.
Memory Speed and Latency
Faster RAM with lower latency improves performance in RPCS3, especially in heavy titles. Pairing your CPU with fast DDR5 memory can give a noticeable boost.
RPCS3 CPU Performance Benchmarks (2025)
Here’s a simplified look at how different tiers perform in popular games:
Game | S-Tier CPUs | A-Tier CPUs | B-Tier CPUs |
Demon’s Souls | 60+ FPS stable | 50–60 FPS | 30–45 FPS |
Persona 5 | 100+ FPS | 80–100 FPS | 60–70 FPS |
Uncharted 3 | 60 FPS | 45–55 FPS | 30–40 FPS |
Ratchet & Clank | 60+ FPS | 50 FPS | 30–40 FPS |
Upcoming CPUs and Future of RPCS3 Performance
Both Intel and AMD are preparing their next-generation chips for 2025 and beyond. Intel’s 15th Gen processors and AMD’s Zen 6 series are expected to bring even higher single-core speeds and better efficiency.
At the same time, the RPCS3 development team continues to optimize the emulator, improving compatibility and performance with each update.
Future builds may reduce CPU requirements slightly, but a strong processor will always be the foundation of smooth gameplay.
RPCS3 GPU tier list
RPCS3 doesn’t rely much on the GPU compared to the CPU. A decent modern graphics card can handle rendering, but the emulator mainly depends on your processor. Any mid-range GPU is usually enough for smooth gameplay.

Is RPCS3 CPU or GPU intensive
RPCS3 is mainly CPU intensive because it must recreate the PS3’s unique Cell processor. While a decent GPU is helpful for visuals, the biggest performance impact always comes from the CPU’s speed, instructions, and overall architecture strength.
RPCS3 Force CPU blit
Force CPU blit is a special RPCS3 setting that moves certain graphics tasks from the GPU to the CPU. It’s mostly used for fixing visual glitches but often reduces performance, so it should only be enabled carefully.
AVX-512 CPU list
AVX-512 is a special instruction set that speeds up RPCS3 greatly. Supported CPUs include Intel’s 11th Gen, some 12th Gen with BIOS tweaks, and newer high-end Xeons. AMD CPUs currently don’t support AVX-512 instructions at all.
