Ready Or Not

The Intel Core i5-11400F and Intel Arc B580 pairing in Ready Or Not delivers a decisive performance curve that hinges on resolution scaling and preset selection. The data shows a 6-core, 12-thread Rocket Lake processor with a 2.60 GHz base and 4.40 GHz boost clock, paired with a Battlemage GPU that carries 12 GB of GDDR6 memory on a 192-bit bus. This combination’s measured frames per second reveal where the bottleneck shifts between CPU and GPU, and the benchmark results indicate that players should treat 1440p as the sweet spot for this tactical shooter.

CPU Role — cores, clocks, and how they relate to this game's results

The Core i5-11400F provides six physical cores with twelve threads, a configuration that matters for Ready Or Not’s AI-driven squad mechanics and dense object interactions. Its 4.40 GHz boost clock offers strong single-thread responsiveness, which is critical for the game’s hit-registration and frame-pacing in firefights. The 12 MB of shared L3 cache helps keep frequently accessed map data close to the cores, reducing stutter during room-to-room transitions.

Benchmark results show this CPU sits in the 75th percentile against all processors, with an average benchmark score of 17181. Its nearest rivals include the AMD Ryzen 7 5700U at a 0% deltaPct and the Intel Core i7-1260P at -0.2% deltaPct, meaning the i5-11400F is statistically tied with those parts in synthetic workloads. For a tactical shooter, this level of compute headroom is sufficient: at 1080p Low, the combo reaches 216.9 FPS average, indicating the CPU is not the limiting factor at lower resolutions.

However, the picture changes at 4K. At 3840x2160 Ultra, the average FPS drops to 40.2, a 73% reduction from the 1080p Low figure. The CPU’s role here is to feed the GPU with draw calls, and the data shows the i5-11400F does not throttle the Arc B580 until the GPU is already saturated. The 3DMark 16-thread score of 5619 and max-thread score of 5652 are nearly identical, confirming that the processor’s scaling plateaus beyond its 12 threads—an expected trait for a 6-core part in a game that typically uses fewer than eight threads. The Cinebench R23 multi-core score of 14372 reinforces that this CPU can sustain high throughput, but Ready Or Not’s average FPS deltas between Low and Medium presets suggest the game leans more on GPU fill-rate than raw CPU muscle.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B580 is the dominant factor in this pairing. Built on TSMC’s 5 nm process with the Xe2-HPG architecture, it runs at a fixed 2670 MHz base and boost clock. Its 12 GB of GDDR6 memory at 19 Gbps effective delivers 456.0 GB/s of bandwidth across a 192-bit bus—a configuration that proves decisive at higher resolutions where texture streaming and shadow buffers expand.

The GPU’s 2560 shading units and 80 ROPs drive the pixel fill-rate of 213.6 GPixel/s, which explains the 1440p results. At 2560x1440 High, the combo averages 108.2 FPS, while Ultra drops to 74.9 FPS—a 31% performance penalty for the highest preset. The 4K data is more telling: 3840x2160 High yields 57.3 FPS, but Ultra falls to 40.2 FPS, a 30% reduction. This aligns with the GPU’s 66th percentile ranking among all GPUs, with an average benchmark score of 23021. Its nearest rival, the NVIDIA GeForce RTX 4060, sits at a -0.7% deltaPct, meaning the Arc B580 is effectively a performance peer to that card in this title’s synthetic metrics.

The 12 GB VRAM buffer is not exhausted at 4K Ultra in these measurements, but the 456.0 GB/s bandwidth becomes a constraint. The difference between 4K Medium (60.5 FPS) and 4K High (57.3 FPS) is only 5%, while the jump from High to Ultra costs 17.1 FPS. That suggests the Ultra preset’s additional texture and shadow quality settings push the ROPs and texture units—160 TMUs producing 427.2 GTexel/s—to their limit. The GPU’s 13.67 TFLOPS FP32 throughput is the ceiling here, and the data shows it is hit hardest at 4K Ultra.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS rows provide a clear hierarchy. At 1920x1080, every preset exceeds 120 FPS, with Low at 216.9, Medium at 189.1, High at 174, and Ultra at 120.3. For competitive play, Low is optimal, but High offers a 45% frame-rate reduction from Low while delivering better visibility for spotting enemies in dark environments. The 1080p Ultra figure of 120.3 FPS remains above the 100 FPS threshold that most tactical shooter players prefer.

At 2560x1440, the choice narrows. Medium averages 115.7 FPS, while High drops to 108.2 FPS—a modest 6% penalty. Ultra, however, falls to 74.9 FPS, a 35% decline from High. The data suggests High is the best balance at 1440p: it stays above 100 FPS and retains the visual fidelity needed for long-range engagements. Medium is a viable alternative if frame consistency is prioritized, but the 7.5 FPS difference between Medium and High is marginal.

For 3840x2160, the landscape is different. Low averages 71.6 FPS, Medium 60.5 FPS, and High 57.3 FPS. Ultra drops to 40.2 FPS, which is below the playable threshold for a game requiring precise aiming. The recommendation is Low at 4K, as it is the only preset that maintains a comfortable frame rate above 70 FPS. Medium is acceptable for cinematic play, but the 11.1 FPS gap between Low and Medium suggests the GPU’s bandwidth is a limiting factor. Overall, the benchmark data indicates that 1440p High is the optimal experience for this combo, delivering 108.2 FPS without the visual sacrifices of Low.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Intel Core i5-11400F + Intel Arc B580 combination ranks 1375th out of 1748 tested combos in Ready Or Not, placing it in the 21st percentile of all configurations. This rank is lower than what the raw FPS numbers might suggest, because the database includes higher-end CPUs and GPUs that push frame rates beyond 200 FPS at 1080p. The combo’s 1080p Ultra average of 120.3 FPS is respectable, but it is outpaced by combos featuring stronger multi-core processors and higher-tier GPUs.

The rank reflects the i5-11400F’s position as a mid-range 2021 processor. Its 75th percentile CPU ranking is offset by the Arc B580’s 66th percentile GPU ranking, and the combination does not exceed the sum of its parts. The nearest GPU rival, the RTX 4060, would likely place higher in the same CPU pairing due to its slightly better average benchmark score, but the deltaPct of -0.7% is within noise. The combo’s weakness is at 4K Ultra, where the 40.2 FPS result drags down its overall standing relative to combos with more powerful GPUs.

That said, the rank of 1375 out of 1748 is not a failure. The data shows this combo outperforms roughly 21% of all tested configurations, and it does so with a CPU that is end-of-life and a GPU that is active in the market. For a 1080p or 1440p gamer, this rank is acceptable, but for anyone targeting 4K, the data suggests looking at higher-ranked combos. The measured FPS at 1440p High (108.2) and 1080p High (174) demonstrate that the combo is well-suited to mainstream resolutions, even if it does not top the charts.
