Inside

The Intel Core i5-12400 and AMD Radeon RX 6750 XT combination delivers a remarkably fluid experience in Inside, with the data indicating that the GPU is the primary performance ceiling only at the most demanding settings. The measured FPS reveals a system that is profoundly overqualified for this puzzle platformer, offering frame rates that far exceed display refresh rates in nearly every configuration. While the absolute scores are high, the scaling pattern between resolutions and settings provides a clear picture of how this specific duo handles the game's workload.

Resolution Scaling

The performance drop from 1080p to 4K is steep but consistent, pointing to a classic GPU-bound scenario at higher resolutions. At High settings, the average frame rate falls from 176.1 FPS at 1920x1080 to 128.9 FPS at 2560x1440, a reduction of roughly 27%. Pushing further to 3840x2160 yields 78.1 FPS, which is a 55% decrease from the 1080p figure. This pattern strongly indicates that the Radeon RX 6750 XT's rendering throughput is the limiting factor as pixel count increases.

The scaling behavior changes dramatically when the preset is lowered. At Low settings, the 1080p result is 317.8 FPS, which drops to 251.8 FPS at 1440p and then to 157.5 FPS at 4K. The fact that 4K Low still produces over 157 FPS suggests that even at high pixel densities, the GPU is not being pushed to its absolute limit in this title. The gap between Low and High settings at 4K is substantial — 157.5 FPS versus 78.1 FPS — which confirms that the graphics card's fill rate and shader performance are the dominant variables in this resolution range.

Interestingly, the scaling from 1440p to 4K is more punishing than from 1080p to 1440p across all settings. For example, at Medium settings, the drop from 1440p (206.2 FPS) to 4K (124.8 FPS) represents a 39% loss, whereas the drop from 1080p (284.1 FPS) to 1440p is only 27%. This non-linear degradation is typical of a GPU that is running out of memory bandwidth or raw compute headroom at higher resolutions. The 12 GB VRAM buffer is not the issue; rather, the 432.0 GB/s bandwidth and 13.31 TFLOPS of FP32 performance are being saturated.

How This Combo Ranks

Within the database of tested combinations, this pairing sits at rank 768 out of 1671 combos, placing it in the upper-middle tier of all possible CPU-GPU pairings for Inside. This percentile position is somewhat surprising given the excellent raw frame rates, but it reflects the fact that many other combinations — particularly those with newer, higher-end GPUs — produce even larger numbers in this undemanding title. The rank indicates that while this combo is far from the top, it is also nowhere near the bottom; it lands in the 54th percentile of all tested systems.

The ranking is likely held back by the GPU's position relative to its peers. The Radeon RX 6750 XT has an average benchmark score of 35327, which is nearly identical to the AMD Radeon RX 5600M (35264, deltaPct 0.2%) and slightly below the NVIDIA GeForce RTX 5070 Ti Mobile (35435, deltaPct -0.3%). In a game where even modest GPUs can achieve high frame rates, the differences between these rivals are marginal, yet they still affect the combo's standing. The i5-12400's average score of 19850 is similarly close to its rivals, with the Intel Core i7-9700 at 19831 (deltaPct 0.1%) and the Intel Core i7-8700 at 19894 (deltaPct -0.2%), meaning neither component dramatically boosts the combo's rank.

What the rank does not capture is the practical experience. A rank of 768 does not mean a poor experience; it simply means that 903 other combinations produce higher average frame rates. For a game like Inside, which is a side-scrolling puzzle platformer without intense action sequences, the difference between 169 FPS and 250 FPS at 1080p Ultra is unlikely to be perceptible to most users. The data shows that this combo delivers a flawless experience even if it does not top the charts.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor based on the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. In Inside, the CPU's role is minimal due to the game's relatively simple physics and logic systems. The benchmark results for the CPU show strong single-thread performance — a 3dmark_single_thread score of 910 and a passmark_single_thread score of 3456 — which is more than sufficient for this title's primary thread. The game does not appear to be heavily multithreaded, as the 3dmark_16_threads score of 5873 is only marginally higher than the 3dmark_8_threads score of 4745, suggesting diminishing returns beyond 8 threads.

The 18 MB of shared L3 cache and 1.25 MB L2 cache per core provide ample fast memory for the game's assets, but this is unlikely to be a bottleneck given the low system requirements of a 2016 puzzle platformer. The fact that the CPU's passmark_multithread score is 18747 and its percentileVsAllCpus is 77 indicates a capable mid-range processor, but in this specific workload, it is likely idling most of the time. The boost clock of 4.40 GHz ensures that any single-threaded bottleneck is easily overcome, and the 65W TDP means thermal throttling is not a concern in standard desktop configurations.

The data suggests that the CPU is not the limiting component at any resolution. Evidence for this comes from the FPS scaling: if the CPU were the bottleneck, we would expect similar frame rates across resolutions at the same settings. Instead, we see a clear decline from 1080p to 4K, which is the signature of GPU limitation. Even at 1080p Low, where the GPU has the least work, the CPU manages to feed it 317.8 FPS, proving that the i5-12400 is not holding back the Radeon RX 6750 XT.

Measured FPS Breakdown

At 1920x1080, the combination produces outstanding results across all presets. Low settings deliver 317.8 FPS, Medium reaches 284.1 FPS, High achieves 176.1 FPS, and Ultra drops to 169 FPS. The relatively small gap between High and Ultra (176.1 vs 169 FPS, a 4% difference) suggests that Ultra's additional effects are not particularly taxing on the GPU. The jump from Low to Medium is also modest, with only a 33.7 FPS difference, indicating that the game's medium preset adds visual quality without a proportional performance cost.

Moving to 2560x1440, the frame rates remain exceptionally high. Low settings produce 251.8 FPS, while Medium hits 206.2 FPS. High and Ultra are closer together at 128.9 FPS and 120.9 FPS, respectively. The difference between High and Ultra at this resolution is 8 FPS, which is even smaller than at 1080p, suggesting that the Ultra preset's additional load is largely resolution-independent. All 1440p results are above 120 FPS, meaning that even the most demanding preset is comfortably playable on high-refresh-rate monitors.

At 3840x2160, the GPU begins to show its limits. Low settings still produce a very playable 157.5 FPS, but Medium drops to 124.8 FPS. High and Ultra fall to 78.1 FPS and 76.2 FPS, respectively. The gap between High and Ultra narrows to just 1.9 FPS at 4K, which is within the margin of error and suggests that the Ultra preset is effectively no more demanding than High at this resolution. The significant drop from Medium to High (124.8 to 78.1 FPS) highlights a clear performance cliff, likely due to specific rendering features enabled in the High preset that are not present in Medium.

FAQ

*Q: Can this combo run Inside at 4K with playable frame rates?*

A: Yes, at Low and Medium settings, the average FPS is 157.5 and 124.8, respectively. High and Ultra settings yield 78.1 and 76.2 FPS, which are still playable but not ideal for high-refresh displays.

Q: What is the best resolution for a 144Hz monitor?

A: At 2560x1440, all presets exceed 120 FPS (Low: 251.8, Medium: 206.2, High: 128.9, Ultra: 120.9), making it the optimal resolution for 144Hz displays. At 1080p, even Ultra surpasses 169 FPS.

Q: How does the i5-12400 compare to its closest CPU rivals?

A: The i5-12400 has an average benchmark score of 19850, which is 0.1% higher than the Intel Core i7-9700 (19831) and 0.2% lower than the Intel Core i7-8700 (19894). The difference is negligible for gaming.

Q: Is the Radeon RX 6750 XT a bottleneck at 1080p?

A: No. At 1080p Low, the combo achieves 317.8 FPS, indicating the CPU is not limiting. The GPU only becomes the limiting factor at higher resolutions or higher presets, such as 4K High where it drops to 78.1 FPS.

Q: What is the frame rate difference between High and Ultra presets?

A: At 1080p, the difference is 7.1 FPS (176.1 vs 169). At 1440p, it is 8 FPS (128.9 vs 120.9). At 4K, it narrows to 1.9 FPS (78.1 vs 76.2). The Ultra preset offers marginal visual improvements for a minimal performance cost.

Q: Does the game use more than 6 CPU cores effectively?

A: The data suggests limited scaling beyond 8 threads. The 3dmark_8_threads score is 4745, while the 16-thread score is 5873, indicating that Inside likely relies on fewer cores, making the i5-12400's 6-core/12-thread configuration more than adequate.

Settings Recommendations

The optimal preset depends on the target resolution and refresh rate. For 1080p users with a 144Hz or 240Hz monitor, the Ultra preset at 169 FPS is the best choice, as it provides the highest visual fidelity while still exceeding the refresh rate of most displays. If the monitor is 360Hz, then dropping to High (176.1 FPS) or Medium (284.1 FPS) is necessary to fully utilize the display, but the visual trade-off may not be worth it given the small FPS difference between High and Ultra.

For 1440p, High settings at 128.9 FPS strike the best balance between visual quality and performance for 120Hz displays. Ultra at 120.9 FPS is also viable, but the 8 FPS gain from dropping to High is negligible. Medium at 206.2 FPS is the choice for 165Hz or 240Hz monitors, though it sacrifices some visual effects. Low at 251.8 FPS is unnecessary unless chasing maximum frame rates on a 240Hz+ panel.

At 4K, the recommendation is clearer. Medium settings at 124.8 FPS are the sweet spot for 120Hz displays, offering a significant improvement over High's 78.1 FPS. Low at 157.5 FPS is only recommended for 144Hz panels, and High or Ultra should be avoided unless the user prioritizes visuals over frame rate and is content with around 76-78 FPS. The data shows that the jump from Medium to High at 4K incurs a massive 46.7 FPS penalty, making it the least efficient setting transition in the entire dataset.

GPU Role

The AMD Radeon RX 6750 XT is the dominant component in this pairing, and its specifications directly explain the observed performance patterns. With 12 GB of GDDR6 memory on a 192-bit bus, the GPU provides 432.0 GB/s of bandwidth, which is more than sufficient for Inside's modest texture requirements. The 2560 shading units and 64 ROPs deliver a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s, which are the key metrics driving the FPS differences between presets and resolutions.

The GPU's clock speeds are notably high, with a base of 2150 MHz and a boost of 2600 MHz. The game clock of 2495 MHz is the typical operating frequency during gaming workloads, and this high clock speed is what allows the GPU to achieve such impressive frame rates at 1080p and 1440p. The FP32 performance of 13.31 TFLOPS is the theoretical peak, and the measured results suggest that Inside is able to utilize a significant portion of this compute power at lower resolutions.

The GPU's benchmark percentile of 79 places it above average among all GPUs, and its average score of 35327 is nearly identical to its nearest rivals. However, the data shows that the RX 6750 XT's performance in Inside is heavily influenced by the preset level. The 4K High result of 78.1 FPS versus the 4K Low result of 157.5 FPS demonstrates that the GPU's fixed-function units (ROPs, TMUs) are the limiting factor when advanced lighting and shadow effects are enabled. The 40 ray accelerators are present on this chip, but Inside does not appear to use ray tracing, meaning the rasterization pipeline is the primary workload. Overall, the GPU is a strong performer for this game, with the only weakness being its inability to maintain high frame rates at 4K with High or Ultra presets.
