Ready Or Not

# Ready Or Not with AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5090

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 5090 delivers exceptional performance in Ready Or Not, ranking 2nd out of 1,748 tested CPU-GPU combinations. This pairing demonstrates that a 6-core Zen 4 processor can fully feed one of the most powerful consumer graphics cards available, producing frame rates that exceed the refresh rates of virtually all mainstream displays across every resolution and settings combination tested. The data reveals a system that is consistently GPU-limited at higher resolutions but shows increasing CPU influence as resolution drops, with the RTX 5090's enormous 32 GB VRAM buffer and 1.79 TB/s bandwidth ensuring no memory-related bottlenecks even at 4K Ultra.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound signature with a strong CPU ceiling emerging at lower resolutions. At High settings, the average FPS drops from 429.2 at 1920x1080 to 268.3 at 2560x1440, representing a 37.5% reduction, then further to 143.8 at 3840x2160, a 46.4% reduction from 1440p. This progressive decline demonstrates that the RTX 5090's rendering workload scales predictably with pixel count, but the relatively modest 37.5% drop from 1080p to 1440p suggests the CPU begins to constrain performance at the lowest resolution.

The Low settings data confirms this interpretation. At 1080p Low, the system produces 537.4 FPS, which is exceptionally high and indicates the Ryzen 5 8400F's 4.70 GHz boost clock is the limiting factor at this resolution. Moving to 1440p Low yields 342.8 FPS (a 36.2% drop), while 4K Low produces 181.1 FPS (a 47.2% drop from 1440p). The fact that 1080p Low does not scale proportionally to 1440p Low — the 36.2% reduction is smaller than the 47.2% drop seen from 1440p to 4K — is strong evidence that at 1080p, the CPU's single-thread performance (3dmark_single_thread score of 951) is preventing the GPU from reaching its full potential.

At Ultra settings, the pattern shifts decisively toward GPU limitation. The 98.7 FPS at 4K Ultra represents a massive 67.1% drop from the 300.5 FPS at 1080p Ultra, and the 191.9 FPS at 1440p Ultra is 36.1% lower than the 1080p result. This steep scaling curve at Ultra settings indicates that the RTX 5090's 104.8 TFLOPS FP32 compute capacity is being fully exercised, with the game's most demanding visual effects overwhelming even this flagship GPU at 4K.

GPU Role

The RTX 5090's specifications are central to understanding the measured results. With 21,760 shading units operating at a boost clock of 2407 MHz, the card delivers 104.8 TFLOPS of FP32 throughput, which is directly reflected in the 4K Ultra performance of 98.7 FPS. The 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, a figure that ensures Ready Or Not's texture streaming and geometry loads never stall the rendering pipeline, even at 4K with Ultra settings where memory pressure would typically be highest.

The card's 176 ROPs and 423.6 GPixel/s pixel rate explain why the resolution scaling at Medium and High settings is so smooth. At 4K Medium, the system achieves 152.9 FPS, and at 4K High it reaches 143.8 FPS — a modest 6.0% penalty for the visual upgrade from Medium to High. This suggests that the RTX 5090's texture rate of 1,636.8 GTexel/s is more than sufficient for Ready Or Not's texture-heavy scenes, with the bottleneck shifting to pixel throughput only at the most demanding Ultra preset.

The GPU's nearest rivals in the benchmark database include the RTX 5090 D with an average score of 84,241 (0.1% higher), the RTX 5050 Mobile at 84,171 (0.2% higher), and the AMD Radeon PRO W6600 at 83,209 (1.3% higher). The RTX 5090's own average benchmark score of 84,306 places it in the 94th percentile of all GPUs, confirming that the measured FPS results in Ready Or Not are consistent with the card's broader computational capabilities.

How This Combo Ranks

The AMD Ryzen 5 8400F + NVIDIA GeForce RTX 5090 combination holds the 2nd position out of 1,748 tested combos in Ready Or Not, placing it in the top 0.1% of all systems benchmarked. This ranking is remarkable given the CPU's modest 6-core/12-thread configuration, which suggests that Ready Or Not is not heavily multithreaded — the game appears to respond more strongly to raw GPU horsepower than to CPU thread count.

The CPU's benchmark profile supports this interpretation. In 3dmark tests, the Ryzen 5 8400F scores 6,165 with max threads but only 951 in single-thread, while Cinebench R23 shows 20,851 multicore and 2,943 singlecore. The nearest CPU rivals include the AMD Ryzen 7 2700X (average score 25,057, 0% delta), the AMD Ryzen AI 5 PRO 340 (25,099, -0.1% delta), and the AMD Ryzen 5 7500F (24,993, 0.3% delta). The 8400F's 82nd percentile ranking among all CPUs, combined with the 2nd place combo ranking, demonstrates that in this game, the GPU dominates the performance equation.

The substantial gap between the 8400F's average benchmark score of 25,064 and its 2nd place combo ranking indicates that Ready Or Not's engine scales efficiently with the RTX 5090's capabilities. The 4K Ultra result of 98.7 FPS, while lower than other settings, still represents a highly playable experience and is likely near the practical limit for this game's most demanding configuration.

Measured FPS Breakdown

At 1920x1080, the system delivers extraordinary frame rates across all settings. Low produces 537.4 FPS, Medium reaches 472 FPS, High achieves 429.2 FPS, and Ultra drops to 300.5 FPS. The 44.1% reduction from Low to Ultra at 1080p indicates that even at this resolution, the GPU is the primary bottleneck — the CPU's capability is demonstrated by the 537.4 FPS Low result, which is among the highest figures recorded in the database.

At 2560x1440, performance remains exceptionally high. Low yields 342.8 FPS, Medium delivers 296.4 FPS, High achieves 268.3 FPS, and Ultra produces 191.9 FPS. The 21.9% drop from Low to Ultra at 1440p is smaller than the 44.1% drop at 1080p, suggesting that the CPU's influence diminishes as resolution increases — the GPU's workload grows, but the CPU's frame preparation time remains constant.

At 3840x2160, the GPU becomes the clear limiting factor. Low produces 181.1 FPS, Medium delivers 152.9 FPS, High achieves 143.8 FPS, and Ultra drops to 98.7 FPS. The 45.5% reduction from Low to Ultra at 4K mirrors the 1080p pattern, but the absolute values indicate that the RTX 5090's pixel rate is the dominant constraint. The 98.7 FPS Ultra result is particularly notable as it demonstrates that even a flagship GPU cannot maintain triple-digit frame rates in Ready Or Not's most demanding mode.

FAQ

A: The 8400F has an average benchmark score of 25,064, which is essentially identical to the AMD Ryzen 7 2700X at 25,057 (0% delta), and slightly higher than the AMD Ryzen 5 7500F at 24,993 (0.3% higher). It trails the AMD Ryzen AI 5 PRO 340 by 0.1%.

Q: Is Ultra settings viable with this combo?

A: Yes, but with caveats. At 1080p Ultra, the system produces 300.5 FPS, and at 1440p Ultra it reaches 191.9 FPS. At 4K Ultra, the 98.7 FPS result is still playable but may not satisfy players targeting 120+ FPS on high-refresh displays.

Settings Recommendations

For players seeking the highest frame rates, the Low preset at 1080p yields 537.4 FPS, while 1440p Low provides 342.8 FPS — both are far beyond any display's refresh capabilities. The Medium preset offers a compelling balance: at 1080p it produces 472 FPS, at 1440p it reaches 296.4 FPS, and at 4K it maintains 152.9 FPS, which exceeds 144 Hz displays at all resolutions.

The High preset is the recommended choice for visual quality without sacrificing performance. At 4K, High produces 143.8 FPS, which is only 6.0% lower than Medium's 152.9 FPS but delivers noticeably better visual fidelity. The Ultra preset at 4K drops to 98.7 FPS, a 31.4% reduction from High, making it suitable only for players with 60-90 Hz displays or those who prioritize maximum image quality over frame rate. For most users, High settings at 1440p (268.3 FPS) or 4K (143.8 FPS) represent the optimal balance of visual quality and performance, with the data clearly showing diminishing returns when moving from High to Ultra.

CPU Role

The AMD Ryzen 5 8400F's 6 cores and 12 threads, based on the Zen 4 Phoenix architecture on a 4 nm process, provide sufficient processing power for Ready Or Not. The CPU's base clock of 4.20 GHz and boost clock of 4.70 GHz allow it to maintain high single-thread performance, as evidenced by its 3dmark single-thread score of 951 and Cinebench R23 singlecore result of 2,943. The 16 MB of shared L3 cache and 83.2 GB/s memory bandwidth contribute to the system's ability to feed the RTX 5090 with frame data.

The CPU's benchmark results show strong multithreaded capability, with a 3dmark max threads score of 6,165 and Cinebench R23 multicore score of 20,851. However, the game's performance pattern — where 1080p Low achieves 537.4 FPS but 1080p Ultra drops to 300.5 FPS — suggests that Ready Or Not's engine is not heavily dependent on CPU thread count. The CPU's 82nd percentile ranking among all processors, combined with its 2nd place combo ranking, indicates that the Ryzen 5 8400F is more than adequate for this game, even when paired with the RTX 5090.

The delta between the CPU's performance at 1080p Low (537.4 FPS) and 4K Ultra (98.7 FPS) demonstrates that the CPU's role diminishes as GPU load increases. The CPU's 65 W TDP and unlocked multiplier suggest headroom for overclocking, which could potentially improve the 1080p Low result, but the data shows that the system's 2nd place ranking out of 1,748 combos leaves minimal room for improvement through CPU tuning alone.
