Ready Or Not

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

The Intel Core i5-9400 is a 6-core, 6-thread processor with no hyper-threading, built on the Coffee Lake architecture at 14 nm. It runs at a 2.90 GHz base clock and boosts to 4.10 GHz, with 9 MB of shared L3 cache. This CPU sits at the 47th percentile among all tested processors, with an average benchmark score of 2254. In Cinebench R23, it scores 6629 multi-core and 935 single-core; in Geekbench, it scores 5141 multi-core and 1389 single-core.

This is a processor from 2018, and its single-threaded performance is modest by current standards. The data shows that in Ready Or Not, the i5-9400 is paired with a GPU that is often the primary bottleneck, so the CPU's six threads are sufficient to feed the RX 570 in most scenarios — but not all. The CPU's nearest rivals in aggregate benchmark score are the Intel Core i7-1068NG7 (0.2% slower), Intel Core i3-10305 (0.4% slower), Intel Core i7-10710U (0.3% faster), and AMD Ryzen 5 PRO 1500 (0.4% faster). These deltas are trivial; the i5-9400 is effectively tied with all of them in raw CPU performance.

For a tactical shooter like Ready Or Not, which relies on dense AI, physics, and environmental destruction, the CPU's six threads can become a limiting factor when the action gets crowded. However, the measured FPS data indicates that at 1080p, even the Ultra preset achieves 60 FPS average, which suggests the CPU is not crippling performance outright. The game is more GPU-bound in this configuration. The i5-9400's lack of multi-threading means it cannot leverage extra logical cores for background tasks, but the game's engine appears to scale adequately with this six-core design at the tested settings.

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

The AMD Radeon RX 570 is a Polaris 20 chip on GCN 4.0 architecture, built at 14 nm by GlobalFoundries. It has 2048 shading units, 128 TMUs, and 32 ROPs. The GPU runs at a 1168 MHz base and 1244 MHz boost clock, with 4 GB of GDDR5 memory on a 256-bit bus delivering 224.0 GB/s bandwidth. Its FP32 performance is 5.095 TFLOPS, and the pixel rate is 39.81 GPixel/s. The card sits at the 74th percentile among all GPUs, with an average benchmark score of 28766.

The 4 GB VRAM is the critical constraint in Ready Or Not. At 4K Ultra, the GPU manages only 20 FPS average; at 4K High, it improves to 28 FPS. The data shows a steep drop as resolution and settings climb, which is consistent with a GPU running out of both memory capacity and raw throughput. The RX 570's nearest rivals in aggregate score are the AMD Radeon RX 6800M (0.4% slower), AMD Radeon R9 M295X (0.7% faster), AMD Radeon RX 470 (0.8% slower), and NVIDIA Quadro RTX 8000 (1.2% faster). The RX 570 is essentially performance-equivalent to these in general benchmarks, but in-game, its 4 GB frame buffer is a hard ceiling.

The GPU's texture rate of 159.2 GTexel/s and ROP count of 32 are adequate for 1080p gaming but quickly become overwhelmed at higher resolutions. The measured data confirms this: at 1080p Low, the combo hits 108 FPS average; at 4K Ultra, it falls to 20 FPS. This is not a CPU limitation — the CPU's six threads are constant across all resolutions, so the FPS collapse at 4K is entirely attributable to the GPU. The RX 570's memory clock of 1750 MHz (7 Gbps effective) is also a bottleneck, as the game's texture streaming demands at Ultra settings exceed what this bandwidth can sustain.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of GPU-bound scaling. At 1080p High, the combo achieves 86 FPS average; at 1440p High, it drops to 54 FPS (a 37% reduction); at 4K High, it falls to 28 FPS (a 48% reduction from 1440p). The scaling from 1080p to 4K is a 3.07x drop in pixel count, but the FPS drops by 67% (from 86 to 28) at High settings — not a linear relationship, indicating that the GPU's memory bandwidth and fill rate are being saturated.

At Low settings, the pattern is similar but less severe: 1080p Low yields 108 FPS, 1440p Low yields 68 FPS (37% drop), and 4K Low yields 36 FPS (47% drop from 1440p). The fact that even Low settings cannot maintain playable FPS at 4K underscores that the RX 570's 4 GB VRAM and 224 GB/s bandwidth are inadequate for this game at that resolution, regardless of graphical complexity.

The Medium settings data includes min/max FPS values, which provide additional insight. At 1080p Medium, the average is 94 FPS with a min of 80 and max of 108. At 1440p Medium, the average drops to 59 FPS with a min of 51 and max of 68. At 4K Medium, the average is 31 FPS with a min of 26 and max of 36. The min FPS at 4K Medium (26) is below what most players would consider smooth, and the gap between min and max (10 FPS) suggests occasional stutters — likely due to VRAM spilling when textures exceed 4 GB.

The limiting component is unambiguous: the CPU's performance is identical across all resolutions, and the FPS scaling tracks the GPU's workload almost perfectly. The i5-9400 has enough headroom at 1080p to push beyond 100 FPS on Low, but the RX 570 cannot maintain even 40 FPS at 4K on any setting. This is a textbook GPU-bound scenario, where the GPU's 4 GB memory and Polaris 20 core are the sole bottlenecks.

FAQ

Q: What is the best settings preset for this combo at 1080p?

A: At 1080p, the Medium preset delivers 94 FPS average (min 80, max 108), which is the highest playable average before the Ultra preset drops to 60 FPS. High settings yield 86 FPS, so Medium offers the best balance of smoothness and visual quality.

Q: Can this combo handle 4K gaming in Ready Or Not?

A: No. The data shows 4K Ultra at 20 FPS, 4K High at 28 FPS, 4K Medium at 31 FPS (min 26), and 4K Low at 36 FPS. All 4K results are below 40 FPS, making the game unplayable at that resolution with this hardware.

Q: Is the CPU or GPU the bigger bottleneck in this game?

A: The GPU is the clear bottleneck. The CPU's six threads are constant across resolutions, while FPS drops dramatically as resolution increases — from 108 FPS at 1080p Low to 36 FPS at 4K Low. This scaling pattern is characteristic of a GPU-bound workload.

Q: How does the RX 570 compare to its closest rivals in aggregate performance?

A: The RX 570 scores 28766 on average, with the RX 6800M at 0.4% slower, the R9 M295X at 0.7% faster, the RX 470 at 0.8% slower, and the Quadro RTX 8000 at 1.2% faster. These are all effectively equivalent in general benchmarks.

Q: What is the FPS difference between Low and Ultra settings at 1440p?

A: At 1440p, Low settings produce 68 FPS average, while Ultra produces 38 FPS. That is a 30 FPS difference (44% reduction) from Low to Ultra, showing that the GPU's performance is heavily dependent on graphical settings.

Q: Does the game ever dip below 60 FPS at 1080p Medium?

A: No. The minimum FPS at 1080p Medium is 80, with an average of 94. The only 1080p preset that dips below 60 FPS is Ultra, which averages exactly 60 FPS with no reported minimum.

How This Combo Ranks

This pairing of Intel Core i5-9400 + AMD Radeon RX 570 ranks 3544 out of 3714 tested combos in Ready Or Not. That places it in the bottom 5% of all configurations — a very low standing. The combo's performance is constrained almost entirely by the RX 570, which is an end-of-life GPU from 2017 with 4 GB VRAM. The CPU, while also aging (2018), is less of a liability because the game's GPU demands outpace its CPU demands at every tested resolution.

The rank of 3544 out of 3714 means that nearly all other tested combinations outperform this one in Ready Or Not. This is expected given the hardware's age: the GPU sits at the 74th percentile among all GPUs, but that percentile is based on aggregate benchmarks that do not account for the game's specific VRAM and bandwidth requirements. In this game, the RX 570's 4 GB frame buffer is a severe handicap, particularly at higher resolutions.

The CPU's 47th percentile ranking is also below average, but its six threads and 4.10 GHz boost clock are sufficient to avoid being the primary bottleneck. The data shows that the combo's FPS is consistently GPU-limited, so upgrading the CPU alone would yield little benefit in this game. The ranking reflects a system that is balanced in CPU-GPU pairing but outdated as a whole, with the GPU being the more urgent upgrade target.

At 1080p, the combo delivers playable performance across all settings. Low settings achieve 108 FPS average, which is the highest recorded value. Medium settings produce 94 FPS with a tight min/max range of 80 to 108, indicating consistent frame pacing. High settings yield 86 FPS, and Ultra drops to exactly 60 FPS average — the minimum threshold for smooth gameplay, but with no reported dips below that.

At 1440p, performance becomes marginal. Low settings maintain 68 FPS, Medium drops to 59 FPS (min 51), High falls to 54 FPS, and Ultra is unplayable at 38 FPS. The min FPS of 51 at Medium settings suggests occasional stutters, likely from VRAM pressure.

At 4K, all presets are below 40 FPS. Low settings produce 36 FPS, Medium averages 31 FPS with a min of 26, High drops to 28 FPS, and Ultra is a slideshow at 20 FPS. No 4K preset is playable, and the Medium min FPS of 26 confirms that the GPU is overwhelmed by the resolution's pixel count and texture demands. The data shows a consistent pattern: the RX 570 is only suitable for 1080p gaming in this title, with 1440p being borderline and 4K being entirely out of reach.
