Ready Or Not

The Intel Core i5-9400 paired with the AMD Radeon RX 9070 presents a fascinating study in bottleneck dynamics for Ready Or Not. The benchmark data reveals a system capable of extreme frame rates at mainstream resolutions, yet one that surrenders significant performance at 4K Ultra settings. This combination sits at rank 639 out of 1748 tested combos, placing it in the 63rd percentile of all configurations. The CPU, a six-core Coffee Lake part with a 50th percentile standing against all processors, provides enough throughput for high-refresh gaming, while the GPU, a RDNA 4.0 part with a 79th percentile ranking, carries the visual load. The interaction between these two components defines the experience across the resolution spectrum.

Resolution Scaling

The frame rate curve from 1080p to 4K illustrates a classic GPU-bound scenario, but with a notable twist at the highest settings. At 1080p Low, the system produces 313 FPS, a figure that suggests the CPU is nearing its operational ceiling. Moving to 1440p Low, the score drops to 219.9 FPS, a 29.7% reduction, which is a predictable scaling pattern. However, at 4K Low, the system still manages 111.5 FPS, indicating that even with a substantial pixel increase, the GPU has enough headroom to maintain playable performance.

The scaling behavior changes dramatically when settings are raised. At High settings, the 1080p result is 274.8 FPS, while 1440p yields 172.4 FPS (a 37.3% drop), and 4K falls to 89.8 FPS (a 67.3% drop from 1080p). This steep decline at 4K High points to the GPU becoming the primary limiting factor. The pattern intensifies at Ultra settings: 1080p delivers 193.1 FPS, 1440p drops to 122.3 FPS, and 4K plummets to 64.7 FPS. The 4K Ultra result is 66.5% slower than the 1080p Ultra figure, demonstrating that the RX 9070's 16 GB frame buffer and 644.6 GB/s bandwidth are being heavily taxed by the game's highest visual fidelity at that resolution.

The data suggests that the i5-9400 is sufficient to feed the RX 9070 at lower resolutions and settings, but the GPU's workload scales aggressively with resolution. The 65W TDP CPU does not appear to be a severe constraint until the system approaches 300 FPS territory, where the 2.90 GHz base and 4.10 GHz boost clocks limit maximum output. For players targeting 1440p, the scaling from High to Ultra costs 50.1 FPS (172.4 to 122.3), a significant trade-off for marginal visual gains. At 4K, the jump from Medium to Ultra costs 36.9 FPS (101.6 to 64.7), which pushes the experience below the 70 FPS threshold many consider minimum for smooth tactical gameplay.

GPU Role

The AMD Radeon RX 9070 is the dominant component in this pairing, dictating performance at higher resolutions. Its boost clock of 2520 MHz and game clock of 2070 MHz provide the computational throughput required for Ready Or Not's tactical environments. The 56 RT cores, while not directly benchmarked in this game's data, contribute to the GPU's overall capability. The 128 ROPs deliver a pixel rate of 322.6 GPixel/s, which directly influences the 4K results.

The memory subsystem is critical to understanding the 4K scaling. With 16 GB of GDDR6 on a 256-bit bus, the GPU achieves 644.6 GB/s of bandwidth. This is the figure that supports 89.8 FPS at 4K High but struggles at 4K Ultra with 64.7 FPS. The 20.1 Gbps effective memory speed is a substantial resource, yet the Ultra preset's demands outpace it. The 36.13 TFLOPS of FP32 compute power is ample for this title, as evidenced by the 219.9 FPS at 1440p Low, but the fill-rate requirements at 4K Ultra expose the limits of the 357 mm² die.

The GPU's 79th percentile standing among all GPUs reflects its position as a high-midrange part. Its nearest rival, the NVIDIA A2, is 0.2% slower on average, while the AMD Radeon HD 7970 is 0.7% slower. This context shows the RX 9070 is not a flagship, but it is well above average. The 220W TDP suggests the card requires adequate cooling, and the 2x 8-pin connectors imply a robust power delivery system is needed, though the data does not include thermal throttling metrics. The PCIe 5.0 x16 interface is backward compatible with the i5-9400's Gen 3 slot, and the benchmark results confirm no bandwidth penalty is evident in the measured frame rates.

How This Combo Ranks

The combination of the i5-9400 and RX 9070 achieves a rank of 639 out of 1,748 tested combos in Ready Or Not. This places it in the top 36.6% of all configurations, a respectable position for a CPU that was end-of-life in 2018 paired with a GPU released in 2025. The ranking reflects the GPU's ability to compensate for the CPU's age. The CPU's 50th percentile standing against all processors is the weak link, but the GPU's 79th percentile partially offsets this deficit.

Compared to other combos that might use a newer mid-range CPU, this pairing loses ground in CPU-bound scenarios. The data does not provide direct comparison to other combos, but the rank implies that roughly 639 configurations outperform it. The delta between the i5-9400 and its nearest CPU rival, the i7-8809G, is only 0.6%, meaning the choice of CPU in this class has minimal impact on the overall ranking. The RX 9070's 0.2% deficit to the NVIDIA A2 in GPU benchmarks is equally small, suggesting that the combo's rank is more dependent on the game's specific engine demands than on synthetic benchmark deltas.

The 4K Ultra result of 64.7 FPS is the single lowest measured score, and it likely drags the combo's rank down relative to configurations with more powerful GPUs. However, the 1080p and 1440p results are strong, with the 1440p High score of 172.4 FPS being particularly competitive. The rank of 639 out of 1,748 is a balanced outcome, indicating that this combo is a viable choice for high-refresh 1080p and 1440p gaming, with acceptable 4K performance only at reduced settings.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest results. Low settings produce 313 FPS, Medium drops to 297.9 FPS, High yields 274.8 FPS, and Ultra reduces performance to 193.1 FPS. The gap between High and Ultra is 81.7 FPS, a 29.7% reduction that suggests Ultra imposes a significant shader load. The 1080p results are uniformly above 190 FPS, making this resolution the sweet spot for high-refresh monitors.

At 2560x1440, the scaling is more pronounced. Low settings achieve 219.9 FPS, Medium hits 191.1 FPS, High manages 172.4 FPS, and Ultra falls to 122.3 FPS. The difference between Low and Ultra is 97.6 FPS, a 44.4% reduction. This resolution still supports competitive frame rates, with even the Ultra preset staying above 120 FPS. The 1440p High result of 172.4 FPS is notably strong for a tactical shooter.

At 3840x2160, the GPU's limits become apparent. Low settings produce 111.5 FPS, Medium yields 101.6 FPS, High drops to 89.8 FPS, and Ultra plummets to 64.7 FPS. The spread from Low to Ultra is 46.8 FPS, a 42% reduction. The 4K Ultra score is the only result below 70 FPS across all measured configurations. The 4K Medium score of 101.6 FPS is the highest 4K result that maintains a triple-digit average, making it the recommended target for 4K displays.

Settings Recommendations

For 1080p and 1440p displays, the High preset offers the best balance of visual fidelity and performance. At 1080p, High delivers 274.8 FPS, which is 29.7% faster than Ultra's 193.1 FPS while providing near-identical visual quality in most tactical scenarios. At 1440p, High's 172.4 FPS is 50.1 FPS faster than Ultra's 122.3 FPS, a significant margin that ensures smooth gameplay during intense firefights. The data indicates that Ultra's additional effects are not worth the frame rate cost on this hardware.

For 4K displays, the Medium preset is the optimal choice. The 101.6 FPS average at 4K Medium is 11.8 FPS faster than High's 89.8 FPS and 36.9 FPS faster than Ultra's 64.7 FPS. The 4K Medium result maintains a comfortable margin above 60 FPS, while the 4K High result is playable but closer to the threshold. The 4K Low preset at 111.5 FPS offers the highest 4K frame rate, but the visual compromise is substantial for a game that relies on environmental cues for tactical awareness.

Players with high-refresh 1080p monitors (240 Hz or higher) can safely use High settings, as the 274.8 FPS result exceeds most display refresh rates. For 1440p 144 Hz monitors, High settings provide 172.4 FPS, which is sufficient headroom. The Ultra preset is only recommended for players who prioritize visual fidelity over frame rate and are willing to accept the 193.1 FPS at 1080p or 122.3 FPS at 1440p. In all cases, the measured data supports avoiding Ultra at 4K, as the 64.7 FPS result falls below the 70 FPS threshold for responsive aiming in a tactical shooter.
