Thief

The pairing of the Intel Core i5-14600KF with the AMD Radeon RX 570 produces a severely GPU-bound experience in Thief, with the data showing that the graphics card is the definitive performance ceiling. Across all resolutions, the range of average frame rates is narrow (20.1 FPS to 72.4 FPS), and the most demanding settings at 4K yield sub-30 FPS averages. The benchmark results indicate that while the CPU has ample headroom, the RX 570’s 4 GB VRAM and Polaris architecture limit the overall experience, making settings and resolution compromises mandatory for playable performance.

Settings Recommendations

For a playable experience at 1920x1080, the Low preset is the only option that provides a substantial performance margin. The data shows an average of 72.4 FPS at this setting, which is 21.1% higher than the Medium preset's 59.8 FPS and 58.1% higher than the High preset's 45.8 FPS. This makes Low the definitive choice for smooth gameplay, as it is the only tested configuration at this resolution that exceeds the 60 FPS threshold.

The Medium preset at 1080p remains viable, with a 59.8 FPS average that is close to the 60 FPS target, but the drop from Low to Medium is steep. The High preset at 45.8 FPS and Ultra at 41.1 FPS are below the smoothness threshold, indicating that the GPU struggles with the additional shading and texture work. At 2560x1440, the data shows a clear hierarchy: Low yields 50.9 FPS, Medium drops to 38.7 FPS, High falls to 29.3 FPS, and Ultra bottoms out at 26.2 FPS. None of these are ideal for fast-paced action, but Low is the only setting that approaches a consistent 50 FPS feel.

At 3840x2160, the results are uniformly poor. The Low preset produces a 33.0 FPS average, while Medium (20.5 FPS), High (20.7 FPS), and Ultra (20.1 FPS) all cluster near the low 20s. The minimal difference between Medium, High, and Ultra at 4K suggests that the 4 GB VRAM buffer is exhausted, and the GPU is bottlenecked by memory capacity rather than raw compute. Consequently, 4K is not a viable target for this combo, and users should prioritize resolution scaling down to 1080p for any semblance of fluidity.

How This Combo Ranks

The combo's position in the database is near the bottom, ranking 1558 out of 1642 tested combinations. This percentile placement, which puts it in the bottom 5% of all combos for Thief, reflects the severe imbalance between the high-end CPU and the entry-level GPU. The data shows that the pairing is not competitive for this title, as the CPU’s potential is wasted when paired with a GPU that cannot keep up with the frame rendering demands.

While the individual components have respectable average benchmark scores—the CPU sits in the 93rd percentile and the GPU in the 74th percentile—the combined result is poor. This indicates that the GPU is the limiting factor, and the combo's rank is a direct consequence of the GPU's inability to translate CPU headroom into higher frame rates. The rank of 1558 suggests that most other tested combos, even those with weaker CPUs, achieve better results in Thief due to having more balanced GPU performance.

GPU Role

The AMD Radeon RX 570 is the primary bottleneck in this configuration. Its 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth, but the capacity is the critical limitation at higher resolutions. The data shows that at 4K, the FPS differences between Medium, High, and Ultra are negligible (20.5, 20.7, and 20.1 FPS, respectively), which strongly suggests that the GPU is running out of VRAM and swapping textures, causing a hard performance cap.

The GPU’s base clock of 1168 MHz and boost clock of 1244 MHz are modest, and its 2048 shading units deliver 5.095 TFLOPS of FP32 compute. These specifications are sufficient for 1080p Low, but the 150 W TDP and dual-slot design are not geared toward high-fidelity rendering. The card's 74th percentile ranking among all GPUs is misleading in this context, as it is based on synthetic benchmarks like 3DMark (880 score) and Geekbench (42752 Vulkan score), which do not reflect real-world Thief performance. The data shows that the GPU's memory capacity is the primary constraint, not its compute throughput.

Measured FPS Breakdown

At 1920x1080, the measured FPS averages show a clear progression: Low leads at 72.4 FPS, followed by Medium at 59.8 FPS, High at 45.8 FPS, and Ultra at 41.1 FPS. The gap between Low and Medium is 12.6 FPS, while the gap between High and Ultra is only 4.7 FPS, indicating diminishing returns at the top end. The 1080p results are the only ones that offer any playable configurations, with Low and Medium meeting standard smoothness expectations.

At 2560x1440, the averages drop significantly: Low at 50.9 FPS, Medium at 38.7 FPS, High at 29.3 FPS, and Ultra at 26.2 FPS. The difference between Low and Medium is 12.2 FPS, which is a substantial cost for a modest visual upgrade. The gap between High and Ultra narrows to 3.1 FPS, again showing the GPU's diminishing returns as settings increase. At 3840x2160, the results are uniformly low: Low at 33.0 FPS, Medium at 20.5 FPS, High at 20.7 FPS, and Ultra at 20.1 FPS. The anomalous peak of Low at 33.0 FPS versus the sub-21 FPS results of the other settings highlights how severely the 4K resolution stresses the VRAM buffer.

Resolution Scaling

The data reveals a steep performance drop when scaling from 1080p to 4K. At Low settings, the FPS drops from 72.4 at 1080p to 50.9 at 1440p (a 29.7% reduction) and then to 33.0 at 4K (a 54.4% reduction from 1080p). This pattern indicates that the GPU is the limiting component, as the frame rate scales almost linearly with the number of pixels rendered.

At High settings, the drop is even more pronounced: 45.8 FPS at 1080p falls to 29.3 FPS at 1440p (a 36.0% drop) and then to 20.7 FPS at 4K (a 54.8% drop from 1080p). The fact that the 4K High and 4K Medium results (20.7 and 20.5 FPS) are nearly identical to 4K Ultra (20.1 FPS) confirms that the GPU is not compute-limited but memory-limited at this resolution. The CPU has no role in this bottleneck, as the i5-14600KF's 14 cores and 20 threads are more than sufficient for this 2014 title.

CPU Role

The Intel Core i5-14600KF plays a minimal role in this game's performance, as the data clearly shows the GPU as the limiting factor. With 14 cores, 20 threads, and a boost clock of 5.30 GHz, the CPU has a 93rd percentile ranking among all CPUs, with an average benchmark score of 49367. Its nearest rival, the Intel Core i5-14600K, scores 49166, a delta of 0.4%, indicating that the KF variant is virtually identical in performance.

The CPU's high single-core performance (4643 in Cinebench R23 single-core) is more than adequate for Thief's engine. The benchmark results show that the CPU is not causing any frame rate limitations, as the FPS differences across resolutions are entirely attributable to the GPU. If the CPU were the bottleneck, the FPS would remain constant regardless of resolution, but the data shows a consistent drop as resolution increases. The CPU's 24 MB of shared L3 cache and dual-channel DDR4/DDR5 memory support provide ample bandwidth for feeding the GPU, but the RX 570's 224.0 GB/s memory bandwidth is the ceiling.
