Evolve

The Intel Core i5-12400 and AMD Radeon RX 7900 XTX pairing presents a fascinating study in bottleneck dynamics when applied to the 2015 title Evolve. This combination of a modern 6-core processor and a flagship RDNA 3.0 GPU produces a wide FPS envelope that reveals how differently the CPU and GPU respond to the game's demands. The data shows a system capable of extremely high frame rates at lower resolutions, yet one that becomes firmly GPU-bound as resolution increases, offering clear insights into where each component's workload begins and ends.

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

The Intel Core i5-12400 brings a configuration of 6 cores and 12 threads, a design that is more than adequate for a 2015-era FPS. Its base clock of 2.50 GHz and boost clock of 4.40 GHz provide the single-thread headroom that older game engines typically favor. The processor sits on the Alder Lake-S architecture, built on a 10 nm process, and its benchmark percentile of 77 versus all CPUs indicates it is a strong performer, though not at the very top of the hierarchy.

Looking at the synthetic benchmarks, the i5-12400’s single-thread score in 3dMark is 910, while its max-thread score reaches 5890. This suggests that Evolve, which likely does not scale perfectly across many cores, will lean heavily on the processor's ability to handle a few demanding threads quickly. The Cinebench R23 multicore score of 15935 shows substantial parallel capability, but the game's results at 1080p suggest that raw multi-threading is not the primary constraint. At 1920x1080 with Low settings, the combo achieves 302.4 FPS, a figure so high that it likely approaches the engine's internal limits or the point where CPU draw-call processing becomes the main hurdle. The processor's 18 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support are also factors; the memory bandwidth available to the CPU can influence frame pacing in CPU-bound scenarios, which is precisely what the 1080p Low data points to.

When comparing this CPU to its nearest rivals, the performance is remarkably tight. The Intel Core i7-9700 has an average score of 19831, a delta of just 0.1% from the i5-12400's 19850 average. Similarly, the Intel Core i7-8700 is only 0.2% behind. This indicates that in a game like Evolve, the 12th-gen i5's architectural advantages are not necessarily yielding a massive lead over older, high-clocked i7 parts, suggesting the game's engine is sensitive to clock speed and per-core efficiency rather than core count alone. The data implies that while the CPU is not weak, its performance headroom is sufficient to feed the GPU at lower resolutions, but the frame rate ceiling at 1080p is likely a collaborative limit of the engine and CPU, not the GPU.

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

The AMD Radeon RX 7900 XTX is a behemoth of a graphics card, featuring 24 GB of GDDR6 memory on a 384-bit bus, yielding a staggering 960.0 GB/s of bandwidth. Its boost clock of 2498 MHz and game clock of 2365 MHz, derived from the Navi 31 chip on a 5 nm process, give it immense rasterization power. The GPU's benchmark percentile of 85 versus all GPUs confirms its high-end status, and its Passmark G3D score of 31238 confirms its raw capability.

In Evolve, the GPU's role becomes the primary determinant of performance at higher resolutions and settings. At 3840x2160 with Ultra settings, the frame rate plummets to 49.3 FPS, a clear sign that the GPU is struggling with the graphical load, despite its massive VRAM buffer. The 24 GB of VRAM is far beyond what Evolve requires, even at 4K, so the bottleneck is not capacity but rather the GPU's compute and fill-rate limits when rendering heavy effects. The card's 61.39 TFLOPS of FP32 performance is being taxed heavily by the Ultra preset, which likely includes demanding ambient occlusion, shadows, and post-processing effects.

The GPU's nearest rivals in the benchmark database are interesting. The NVIDIA GeForce RTX 4070 Ti is 2% ahead in average score, while the AMD Radeon Pro 580 is 0.4% behind. This proximity in synthetic scores, however, does not directly translate to Evolve performance, as the game's specific rendering paths favor certain architectures. The 7900 XTX's performance at 1440p High (122.3 FPS) and 4K High (71.5 FPS) shows a scaling curve that is steep, indicating that the GPU is the dominant factor in these scenarios. The data suggests that for a game released in 2015, this GPU provides an overwhelming amount of horsepower, but the Ultra preset at 4K still manages to bring it to its knees, highlighting that software settings can outpace hardware capabilities even years later.

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

The measured FPS data across resolutions tells a definitive story about component limits. At 1920x1080 with Low settings, the system produces 302.4 FPS. Moving to 2560x1440 at the same settings, the frame rate drops to 205.9 FPS, a decrease of 96.5 FPS. This substantial drop indicates that even at Low settings, the resolution increase begins to shift the load onto the GPU, though the CPU is still keeping up relatively well. However, the jump to 3840x2160 at Low settings yields 118 FPS, a further drop of 87.9 FPS. This linear degradation is characteristic of a GPU-bound scenario.

The scaling pattern changes dramatically when looking at Ultra settings. At 1080p Ultra, the combo hits 126.7 FPS. At 1440p Ultra, it drops to 87.2 FPS, and at 4K Ultra, it falls to 49.3 FPS. The percentage drop from 1080p to 1440p is roughly 31%, while from 1440p to 4K it is roughly 43%. This non-linear scaling at higher settings is a classic sign of the GPU being the primary limiter. The GPU is processing more pixels and more complex shaders, and its compute units are saturated.

This data implies that at 1080p, especially at Low and Medium settings, the system is partially CPU-limited or engine-limited, as the GPU has headroom to render far more frames. The high frame rates at 1080p (302.4 FPS on Low) suggest that the CPU is the bottleneck, as the GPU would likely be capable of higher numbers if the CPU could feed it faster. As resolution increases, the GPU's workload expands, and the bottleneck shifts decisively to the graphics card. The 4K Ultra result of 49.3 FPS is a clear indicator that the GPU is working at its maximum capacity for this game, while the CPU is likely waiting idly for the next frame to be ready.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i5-12400 and AMD Radeon RX 7900 XTX ranks at position 231 out of 1695 tested combos in Evolve. This places it in the top 14% of all configurations tested, which is a strong showing for a mid-range CPU paired with a high-end GPU. The rank is likely held back by the CPU's performance in the lower resolution scenarios, where the i5-12400's limits become apparent. In combos with higher-end CPUs, such as those with more cores or higher boost clocks, the 1080p frame rates could be higher, pushing those combinations up the list.

The rank of 231 is respectable, but the data suggests that the GPU is not being fully utilized at 1080p. If the CPU were stronger, the combo could potentially rank higher, as the GPU's ceiling is likely much higher than what the i5-12400 allows at lower resolutions. However, at 4K, the combo's rank would likely be much higher, as the GPU becomes the limiting factor and the CPU's role diminishes. This bifurcated performance profile means the overall rank of 231 is an average of very high performance at high resolutions and slightly less impressive performance at low resolutions. The percentile of the CPU (77) and GPU (85) individually suggests they are both solid parts, but their synergy in this specific game is capped by the CPU at low resolutions, preventing the combo from cracking the top 200.

FAQ

Q: Why does the frame rate drop so significantly between 1080p and 1440p at Low settings?

A: The drop from 302.4 FPS at 1920x1080 to 205.9 FPS at 2560x1440 indicates that the GPU is starting to become more involved. Even at Low settings, the increased pixel count (from roughly 2 million to 3.7 million pixels) adds a substantial workload to the graphics card, causing the frame rate to fall even though the CPU is likely still the primary limiter at 1080p.

Q: Is the CPU or GPU the bottleneck at 4K Ultra settings?

A: The data shows that at 3840x2160 with Ultra settings, the frame rate is 49.3 FPS. This low number, combined with the high graphical load, clearly indicates the AMD Radeon RX 7900 XTX is the limiting component. The CPU's workload does not scale significantly with resolution, so the GPU's compute and memory resources are being maxed out by the Ultra preset at 4K.

Q: How does this combo compare to using a higher-end CPU?

A: The combo's rank of 231 out of 1695 is partly determined by the CPU's performance at lower resolutions. The i5-12400's 3dMark max-thread score of 5890 shows it has limits. A CPU with a higher single-thread score could potentially push the 1080p frame rates higher, but the GPU's performance at 4K would remain unchanged, meaning the overall rank could improve but not dramatically.

Q: Is the 24 GB VRAM necessary for this game?

A: No. Evolve is a 2015 title, and the 24 GB of VRAM on the RX 7900 XTX is far more than the game can utilize. The bottleneck at 4K Ultra is not memory capacity but the GPU's processing power, as indicated by the 49.3 FPS result. The VRAM headroom is irrelevant to the performance in this specific game.

Q: What is the best settings preset for a 1440p monitor?

A: At 2560x1440, the High preset yields 122.3 FPS, which is a smooth and responsive experience. The Medium preset offers 161 FPS, which is even higher, but the visual quality difference may not justify the extra frames. The Ultra preset at 87.2 FPS is still playable but shows a significant performance cost for the extra visual fidelity.

Q: Does the 1080p performance indicate a CPU limitation?

A: Yes, the 302.4 FPS result at 1920x1080 with Low settings suggests that the CPU is the limiting factor. The GPU is powerful enough to render more frames, but the Intel Core i5-12400's ability to process the game's draw calls and physics calculations caps the frame rate at that level. This is a common scenario in older games on high-end GPUs.

Settings Recommendations

For this specific combination, the optimal experience depends on the target resolution and refresh rate. At 1920x1080, the High preset at 187.1 FPS offers an excellent balance of visual quality and performance, especially for high-refresh-rate monitors. The Ultra preset at 126.7 FPS is also viable, but the drop to 126.7 FPS from 187.1 FPS at High suggests that the extra visual effects are very costly. For most users, the High preset at 1080p is the sweet spot, providing a large margin over the 144Hz threshold.

At 2560x1440, the High preset at 122.3 FPS is the best choice, as it stays above the 120 FPS mark and provides a great visual experience. The Medium preset at 161 FPS is also excellent for competitive play, but the High preset's visual improvements are likely worth the slight frame rate reduction. The Ultra preset at 87.2 FPS is playable but dips below the 90 FPS mark, which may be noticeable on a 144Hz monitor. For a 4K display, the situation is more constrained. The High preset at 71.5 FPS is the most balanced option, as it provides smooth gameplay on a 60Hz display. The Medium preset at 91.3 FPS is also an option for those who prefer higher frame rates, but the Ultra preset at 49.3 FPS should be avoided due to its sub-60 FPS average, which can feel inconsistent. The Low preset at 4K yields 118 FPS, but the visual compromise is substantial, making High the recommended choice for quality and playability.

Measured FPS Breakdown

At 1920x1080, the performance envelope is wide, with the Low preset achieving an average of 302.4 FPS, the Medium preset at 236.3 FPS, and the High preset at 187.1 FPS. The Ultra preset drops to 126.7 FPS, showing a clear performance hierarchy across the settings.

Moving to 2560x1440, the frame rates remain high, with Low at 205.9 FPS, Medium at 161 FPS, and High at 122.3 FPS. The Ultra preset at 87.2 FPS is the only one that falls below the 100 FPS mark, indicating a significant jump in graphical demands.

At 3840x2160, the GPU is heavily taxed. The Low preset produces 118 FPS, which is still very playable. The Medium preset follows at 91.3 FPS, and the High preset at 71.5 FPS. The Ultra preset is the most demanding, resulting in just 49.3 FPS, which is below the standard 60 FPS target and shows the limits of even this flagship GPU when pushed to maximum settings at 4K resolution.
