Thief

The Intel Core i5-12400F paired with the AMD Radeon RX 5700 XT delivers its most compelling performance at 1080p, where it achieves a peak average of 154.1 FPS on Low settings, but the data clearly shows that this combination is heavily GPU-limited as resolution increases. At 4K Ultra, the system drops to 34.2 FPS, which is below the 60 FPS threshold for smooth gameplay, indicating that the graphics card is the primary bottleneck in demanding scenarios.

Resolution Scaling

The performance degradation from 1080p to 4K is steep and consistent across all settings presets, revealing a classic GPU-bound workload. At Low settings, the average frame rate falls from 154.1 FPS at 1920x1080 to 60.3 FPS at 3840x2160, representing a 60.9% reduction in throughput. This dramatic drop is expected, as the Radeon RX 5700 XT’s 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are pushed to their limits by the fourfold increase in pixel count.

The scaling pattern becomes more pronounced at higher quality presets. Moving from 1080p to 4K at Medium settings reduces performance from 117.8 FPS to 46.3 FPS, a 60.7% decline, while High settings see a similar 62.7% drop from 90.9 FPS to 33.9 FPS. The Ultra preset shows the most severe scaling, with average FPS falling from 84.4 at 1080p to just 34.2 at 4K, a 59.5% reduction. These consistent drops across all settings confirm that the limiting component is the GPU, not the CPU.

At 1440p, the system occupies a middle ground, with Low settings achieving 106.4 FPS and Ultra reaching 59.6 FPS. The 1440p High preset’s 58.7 FPS is nearly identical to the 4K Low result of 60.3 FPS, suggesting that the GPU’s pixel throughput ceiling is being approached in both scenarios. The data indicates that 1440p Ultra is the highest resolution and settings combination that maintains playable frame rates, barely exceeding the 60 FPS threshold.

GPU Role

The AMD Radeon RX 5700 XT, built on the RDNA 1.0 architecture with a 7 nm process from TSMC, provides the graphical muscle for this combination. Its 2560 shading units and 64 ROPs deliver a pixel rate of 121.9 GPixel/s and a texture rate of 304.8 GTexel/s, with FP32 performance rated at 9.754 TFLOPS. The GPU’s boost clock of 1905 MHz and game clock of 1755 MHz are the key drivers behind the observed frame rates, with the base clock set at 1605 MHz.

Memory configuration plays a critical role in Thief’s performance, particularly at higher resolutions. The 8 GB GDDR6 memory operates at 1750 MHz (14 Gbps effective) across a 256-bit bus, yielding 448.0 GB/s of bandwidth. This bandwidth is sufficient for 1080p and 1440p gameplay, but at 4K Ultra, the combination of increased pixel fill and texture demands likely saturates the memory subsystem, contributing to the sub-60 FPS results.

The GPU’s benchmark scores corroborate its mid-range positioning. It achieves a passmark G3D score of 16277 and a 3DMark Steel Nomad DX12 score of 2134, with a percentile rank of 68 among all GPUs. Its nearest rival, the NVIDIA RTX A5000 Mobile, scores 24763, a negligible 0.1% difference, while the Intel Arc A350M trails by 0.3%. These close margins suggest the RX 5700 XT remains competitive with newer mobile solutions despite its 2019 release date and end-of-life production status.

Settings Recommendations

For the best balance of visual quality and performance, the Medium preset at 1440p emerges as the optimal choice, delivering 79.4 FPS average. This configuration provides a comfortable margin above the 60 FPS threshold while retaining most visual fidelity. At 1080p, High settings achieve 90.9 FPS, which is ideal for competitive play or high-refresh-rate displays, while Ultra at 1080p still produces a respectable 84.4 FPS.

Players prioritizing maximum frame rates should select Low settings, which yield 154.1 FPS at 1080p and 106.4 FPS at 1440p. However, the visual compromise is substantial. For 4K gaming, only Low settings (60.3 FPS) reach playable levels, while Medium (46.3 FPS), High (33.9 FPS), and Ultra (34.2 FPS) all fall below 60 FPS, making them unsuitable for smooth gameplay on this hardware combination.

The data suggests that 1440p Medium is the sweet spot, offering 79.4 FPS with moderate visual enhancements over Low settings. The jump from Medium to High at 1440p costs 20.7 FPS (from 79.4 to 58.7), a significant penalty for marginal visual gains. Conversely, the difference between Low and Medium at 1440p is 27 FPS (from 106.4 to 79.4), indicating that Medium provides substantially better visuals without sacrificing too much performance.

CPU Role

The Intel Core i5-12400F provides a solid foundation for this gaming combination, though its influence on Thief’s frame rates is secondary to the GPU. This 6-core, 12-thread processor from the Alder Lake architecture operates at a base clock of 2.50 GHz and boosts up to 4.40 GHz, with a 65 W TDP. Its 18 MB of shared L3 cache and 1.25 MB per-core L2 cache ensure ample data throughput for game logic and physics calculations.

Synthetic benchmarks demonstrate the CPU’s capability. It scores 16518 in Cinebench R23 multicore and 2332 in single-core, while Geekbench results show 9138 multicore and 2221 single-core. The PassMark multithread score of 19433 and single-thread score of 3481 place it in the 77th percentile among all CPUs. Its nearest rival, the Intel Core i7-8700K, scores 19210, just 0.1% lower, while the AMD Ryzen 5 7533HS trails by 0.7%.

In Thief, the CPU’s 12 threads are more than sufficient to feed the GPU at 1080p, where frame rates exceed 150 FPS on Low settings. The bottleneck shifts entirely to the GPU as resolution increases, with the CPU’s 4.40 GHz boost clock ensuring minimal frame pacing issues. The 3DMark results, showing 5895 for 16 threads and 909 for single-thread, indicate balanced multi-threaded and single-threaded performance that suits this stealth game’s CPU demands.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest results across all presets. Low settings achieve 154.1 FPS, Medium 117.8 FPS, High 90.9 FPS, and Ultra 84.4 FPS. The difference between High and Ultra is just 6.5 FPS, suggesting diminishing returns at the highest preset. At 2560x1440, performance scales predictably: Low yields 106.4 FPS, Medium 79.4 FPS, High 58.7 FPS, and Ultra 59.6 FPS. Notably, Ultra slightly outperforms High at 1440p, an anomaly likely due to variable scene complexity during measurement.

The 3840x2160 results reveal the GPU’s limits. Low settings produce 60.3 FPS, which is barely playable, while Medium drops to 46.3 FPS. High and Ultra presets are nearly identical at 33.9 and 34.2 FPS respectively, indicating that the GPU’s pixel throughput is saturated regardless of minor settings changes. The data shows a clear pattern: each resolution step down from 1080p costs roughly 30-40% of frame rate at any given preset, with the most severe absolute drops occurring at Low settings due to their higher baseline FPS.

How This Combo Ranks

This Intel Core i5-12400F and AMD Radeon RX 5700 XT combination ranks 1251 out of 1642 tested combos for Thief, placing it in the lower-middle tier of the database. This ranking reflects the GPU’s age and mid-range positioning rather than any CPU deficiency, as the processor’s synthetic scores place it in the top quarter of all CPUs. The combo’s percentile position is consistent with the RX 5700 XT’s 68th percentile among GPUs, suggesting that the graphics card drags down the overall ranking.

The ranking implies that many other CPU-GPU pairings deliver higher frame rates in Thief, particularly those with more powerful graphics cards. However, the data also shows this combo is far from the bottom, with 391 combinations ranking below it. For a 1080p gaming setup, this pairing offers competitive performance, but for 4K gaming, it falls short of the top-tier results seen in higher-ranked configurations. The 1440p Medium result of 79.4 FPS represents the combo’s most favorable position relative to its rank, offering a playable experience that justifies its mid-pack standing.
