Inside

Measured FPS Breakdown

At 3840x2160, the Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5080 delivers a measured average of 131 FPS on High settings. Dropping to Low settings raises the average to 170 FPS, while Medium settings produce a 157 FPS average with recorded minimum and maximum values of 133 FPS and 181 FPS respectively. The Ultra preset, the most demanding configuration tested, yields an average of 129 FPS at this resolution.

Moving to 2560x1440, the same combination produces an average of 153 FPS on High settings. The Low preset reaches 199 FPS on average, and Medium settings record a 183 FPS average with a minimum of 156 FPS and a maximum of 211 FPS. Ultra settings at 1440p deliver a 150 FPS average, which is notably higher than the 129 FPS average seen at 4K Ultra.

At 1920x1080, the frame rates scale upward across all presets. High settings average 171 FPS, Low settings average 222 FPS, and Medium settings average 205 FPS with minimum and maximum readings of 174 FPS and 235 FPS. The Ultra preset at 1080p achieves a 168 FPS average, making it the highest Ultra result across the three resolutions.

The pattern across all settings is consistent: Low always yields the highest average FPS, followed by Medium, then High, then Ultra. The gap between Low and Ultra narrows as resolution decreases. At 4K, the difference between Low (170 FPS) and Ultra (129 FPS) is 41 FPS. At 1440p, the spread is 49 FPS (199 versus 150). At 1080p, the spread is 54 FPS (222 versus 168). In relative terms, Ultra is approximately 24% slower than Low at 4K, roughly 25% slower at 1440p, and about 24% slower at 1080p, indicating that the preset scaling remains fairly uniform across resolutions.

CPU and GPU Roles

The recorded data shows that the GeForce RTX 5080 is the dominant component in this pairing for Inside, but the degree of GPU influence shifts with resolution. At 3840x2160, the GPU workload is heaviest, which is reflected in the larger absolute frame rate differences between presets. The jump from Low to Medium at 4K costs 13 FPS (170 to 157), while the jump from High to Ultra costs only 2 FPS (131 to 129). This compression at the top end suggests that Ultra is not substantially more demanding than High at 4K, at least for this game.

At 2560x1440, the scaling pattern changes. Low to Medium drops from 199 to 183 FPS, a 16 FPS reduction. High to Ultra drops from 153 to 150 FPS, a mere 3 FPS difference. The 1440p results are uniformly higher than their 4K counterparts, with the largest resolution-based gap appearing at Low settings: 199 FPS versus 170 FPS, a 29 FPS difference. The smallest resolution gap appears at Ultra, where 1440p is only 21 FPS ahead of 4K.

At 1920x1080, the CPU begins to matter more relative to the GPU, though the RTX 5080 still carries the load. The 1080p Low result of 222 FPS is only 23 FPS higher than the 1440p Low result of 199 FPS, and the 1080p Ultra result of 168 FPS is just 18 FPS higher than 1440p Ultra. This compression between 1440p and 1080p indicates that the i5-9400's six threads are starting to limit the upper bound of frame delivery, since the GPU has more headroom at lower resolutions than the CPU can feed. The 6-core, 6-thread configuration with a 2.90 GHz base and 4.10 GHz boost clock appears sufficient to keep the RTX 5080 well occupied, but the diminishing returns from 1440p to 1080p point to CPU involvement in the highest FPS ranges.

The i5-9400 sits at the 47th percentile among all CPUs in the database, with an average benchmark score of 2254. Its nearest rivals are all within a fraction of a percent in score, meaning the CPU is an average performer by database standards. The RTX 5080, by contrast, sits at the 87th percentile among all GPUs with an average benchmark score of 56083. This massive disparity in percentile ranking explains why the GPU dictates most of the measured FPS behavior, while the CPU only becomes a noticeable factor at 1080p where frame rates approach the 222 FPS mark.

How This Combo Ranks

Within the database of tested combinations for Inside, this specific pairing of the Intel Core i5-9400 and NVIDIA GeForce RTX 5080 ranks 1784 out of 3716 total combos. This places it just below the midpoint of all tested configurations, which is a meaningful result given the individual component percentiles. The GPU is in the 87th percentile, but the CPU is only in the 47th percentile, so the overall combo ranking reflects the weaker link in the chain.

The rank of 1784 out of 3716 means that roughly 48% of tested combos perform better in this game, while 52% perform worse. For a game like Inside, a puzzle platformer from 2016, the absolute frame rates are exceptionally high across all settings, so the combo rank is more a reflection of how other high-end GPU pairings behave than a statement about playability. The recorded data shows every preset at every resolution clears 129 FPS on average, which is far beyond the 60 FPS playable threshold used by the database.

The gap between the combo's rank and the GPU's individual percentile suggests that pairing this GPU with a stronger CPU would likely move the combo higher in the rankings, particularly at 1080p where the CPU constraint becomes visible. Conversely, the combo rank also indicates that the i5-9400, despite being a mid-pack CPU, does not drag the RTX 5080 down to unplayable levels in this title.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-9400, based on average benchmark score, include the Intel Core i7-1068NG7 with an average score of 2259, which is 0.2% faster, and the Intel Core i3-10305 with an average score of 2264, which is 0.4% faster. On the slower side, the Intel Core i7-10710U scores 2248 on average, 0.3% slower, and the AMD Ryzen 5 PRO 1500 scores 2246, 0.4% slower. Any of these CPUs would behave nearly identically to the i5-9400 in Inside, since the delta percentages are all below half a percent. A system builder swapping the i5-9400 for any of these four alternatives would see no meaningful change in frame rates.

For the NVIDIA GeForce RTX 5080, the nearest GPU rivals are the AMD Radeon 8060S with an average score of 55757, 0.6% slower, and the AMD Radeon RX 6750 GRE 12 GB with an average score of 55698, 0.7% slower. The AMD Radeon Pro W5700X scores 54828, 2.3% slower, while the AMD Radeon RX 9070 GRE scores 57367, 2.2% faster. These deltas are still small enough that all five GPUs would produce nearly indistinguishable frame rates in Inside. The RX 9070 GRE is the only rival that would deliver measurably higher FPS, and even that difference would be modest given the game's low overall demand.

Combining these two sets of alternatives, a system with an i7-1068NG7 and an RX 9070 GRE would be the closest faster configuration, while an i7-10710U with an RX 6750 GRE 12 GB would be the closest slower configuration. The benchmark data indicates that all of these permutations would remain well above the 60 FPS threshold at every resolution and preset.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 129 FPS. The database lists all four presets (High, Low, Medium, Ultra) as playable at 4K, so the best settings recommendation is Ultra. The minimum recorded frame rate at 4K Medium is 133 FPS, and there are no recorded minimums below that threshold for any preset, which means even the lowest observed frame rates do not approach the playable limit.

At 2560x1440, the best settings are again Ultra, with an average of 150 FPS. All four presets are playable. The Medium preset records a minimum of 156 FPS and a maximum of 211 FPS, showing that even the slower frames at 1440p are more than double the 60 FPS threshold.

At 1920x1080, the best settings remain Ultra, with an average of 168 FPS. The Medium preset records a minimum of 174 FPS and a maximum of 235 FPS, and the Low preset averages 222 FPS. The recommendation at every resolution is the same: run the game at Ultra, because the hardware has enough headroom to do so without dropping below 60 FPS.

The Verdict

This PC can run Inside without any difficulty. The verdict by resolution is uniform: at 3840x2160, 2560x1440, and 1920x1080, all four tested settings are playable, and the best settings choice is Ultra in every case. The recorded averages are 129 FPS at 4K Ultra, 150 FPS at 1440p Ultra, and 168 FPS at 1080p Ultra. The lowest average across all tested configurations is 129 FPS, which is more than double the 60 FPS playable threshold.

The data indicates that the RTX 5080 is the primary driver of performance, with the i5-9400 providing sufficient CPU throughput for this title. The game's 2016 release date and puzzle platformer genre mean it is not a demanding workload by modern standards, and the benchmark results confirm that this combination has substantial performance reserves. Even the most conservative interpretation of the measured data, accounting for the minimum FPS values recorded at Medium settings (133 FPS at 4K, 156 FPS at 1440p, 174 FPS at 1080p), shows no scenario where the system drops near the 60 FPS line.

Users who own this combination can enable Ultra settings at any resolution without concern. The only practical consideration is whether the display supports the frame rates being produced, since the system is capable of outputting up to 235 FPS at 1080p Medium and 222 FPS at 1080p Low.
