Thief

The Intel Core i5-12600KF paired with the AMD Radeon RX 6800 XT delivers a strong performance profile in Thief, with the data revealing a system that scales predictably across resolutions and settings. The measured FPS across 4K, 1440p, and 1080p shows a clear narrative: the GPU is the primary driver of performance at higher resolutions, while the CPU’s headroom becomes more apparent at lower settings and resolutions. This analysis walks through the measured results step by step, interpreting what the numbers mean for this specific combination.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, indicating a GPU-bound scenario at higher resolutions. At Ultra settings, the average FPS falls from 132.1 at 1080p to 91.0 at 1440p, a reduction of roughly 31%. Moving further to 4K Ultra, the average drops to 54.4 FPS, which is only about 41% of the 1080p Ultra figure. This steep decline highlights that the Radeon RX 6800 XT is the limiting factor as pixel count increases, a typical pattern for a demanding title.

The scaling at Low settings tells a different story. At 1080p Low, the system achieves an average of 192.9 FPS, while at 1440p Low it reaches 160.2 FPS. At 4K Low, the average is 92.5 FPS. The percentage drop from 1080p Low to 4K Low is about 52%, which is less severe than the Ultra scaling drop of 59% (from 132.1 to 54.4). This suggests that at lower settings, the CPU begins to play a more significant role, but the GPU still carries the bulk of the load. The gap between 1080p and 1440p at Low settings (192.9 vs. 160.2, a 17% drop) is smaller than the gap between 1440p and 4K (160.2 vs. 92.5, a 42% drop), emphasizing that 4K resolution imposes a heavy burden on the GPU regardless of settings.

Comparing High settings across resolutions reinforces this. The average at 1080p High is 134.4 FPS, at 1440p High it is 94.3 FPS, and at 4K High it falls to 57.6 FPS. The relative performance at 4K High is only 42.8% of the 1080p High result, which is nearly identical to the Ultra scaling ratio. This consistency suggests that the GPU’s rendering workload scales almost linearly with resolution when settings are high, leaving little room for CPU intervention. The data points to a system where the i5-12600KF has ample headroom at 1080p, but the RX 6800 XT’s limits become the bottleneck at 4K, particularly when visual fidelity is maxed out.

GPU Role

The AMD Radeon RX 6800 XT is the central component in these results, and its specifications align with the observed performance. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 512.0 GB/s. This memory capacity and bandwidth are sufficient for the demands of Thief at 4K, where the game’s textures and geometry require substantial data throughput. The measured 4K Ultra average of 54.4 FPS, while playable, shows the card operating near its limits under maximum load.

Clock speeds further explain the scaling behavior. The GPU has a base clock of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz. The difference between game and boost clocks indicates that the card can dynamically adjust its frequency based on thermal and power headroom. In this benchmark, the sustained performance across resolutions suggests that the card is maintaining high clocks under load, but the drop to 54.4 FPS at 4K Ultra points to the GPU being fully saturated. The pixel rate of 288.0 GPixel/s and texture rate of 648.0 GTexel/s are the raw throughput metrics that dictate how quickly the card can fill frames, and these are the resources being taxed as resolution increases.

The GPU’s standing relative to other cards, with a percentile of 87 among all GPUs, supports its position as a high-end part. Its nearest rivals include the NVIDIA GeForce RTX 4070 Ti SUPER, which has an average score 2.6% higher, and the Intel Arc A550M, which is 0.5% lower. This competitive placement means the RX 6800 XT is not an outlier but rather a well-matched partner for the i5-12600KF. The CPU’s own percentile of 84 among all CPUs further reinforces that this is a balanced pairing, where neither component drastically outclasses the other in a way that would create a lopsided bottleneck in Thief.

How This Combo Ranks

This specific combination of the Intel Core i5-12600KF and AMD Radeon RX 6800 XT ranks 426th out of 1642 tested combos in Thief. This places the pairing in the top 26% of all configurations, a solid result for a system aimed at high-refresh-rate gaming. The rank is a composite measure that takes into account the measured FPS across all resolutions and settings, giving a holistic view of performance. Given the GPU’s 87th percentile and the CPU’s 84th percentile, this ranking is consistent with what one would expect from two components that are both above average but not at the very top of their respective tiers.

The rank of 426 suggests that while this combo is powerful, there are many other pairings that achieve higher frame rates in this game. This is largely due to the GPU’s performance ceiling at 4K Ultra, where the 54.4 FPS average holds back the overall score. At 1080p and 1440p, the system is competitive, but the 4K results drag the rank down relative to combos with even stronger graphics cards. The data implies that users prioritizing 4K Ultra should look to higher-tier GPUs, but for 1440p gaming, this combo is well-positioned.

The deltaPct values for the CPU’s nearest rivals show that the i5-12600KF is virtually tied with the Intel Core i9-10900K (0% difference) and the Intel Core i5-12600K (-0.1% difference). This means the CPU choice is not a differentiator in Thief; the GPU dominates the performance outcome. Similarly, the GPU’s nearest rivals, such as the NVIDIA GeForce RTX 4070 Ti SUPER at 2.6% higher average score, indicate that small GPU upgrades would not drastically alter the ranking. The combo’s 426th position is thus a reflection of the GPU’s mid-to-high tier standing rather than any CPU limitation.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and desired frame rate. At 1080p, the High preset delivers an average of 134.4 FPS, which is only slightly lower than the 192.9 FPS of Low but offers significantly better visual quality. The Ultra preset at 1080p yields 132.1 FPS, a negligible 2.3 FPS drop from High, making Ultra the best choice for 1080p users who want maximum fidelity without sacrificing smoothness. The Medium preset at 1080p averages 172.7 FPS, which is higher than High but lower than Low, so it serves as a middle ground for those who want a frame rate buffer.

At 1440p, the High preset provides an average of 94.3 FPS, which is a comfortable level for most displays. The Ultra preset at 1440p drops to 91.0 FPS, a difference of 3.3 FPS, so High is the recommended choice to maintain a slight performance cushion. The Medium preset at 1440p averages 122.7 FPS, offering a substantial boost over High for competitive play, but the visual trade-off may not be worth it for a single-player stealth title. The Low preset at 1440p reaches 160.2 FPS, but the graphical compromises are likely too severe for the genre.

For 4K, the situation is more constrained. The High preset averages 57.6 FPS, which is above the 54.4 FPS of Ultra but still below a smooth 60 FPS threshold. The Medium preset at 4K yields 72.9 FPS, which is a better target for fluid gameplay, though it requires a reduction in visual detail. The Low preset at 4K achieves 92.5 FPS, but the image quality will be noticeably degraded. The measured data suggests that for 4K, the Medium preset offers the best balance of playability and fidelity, as it is the highest setting that consistently breaks 70 FPS. For 1440p and 1080p, the Ultra preset is recommended for the best experience, as the frame rate impact is minimal relative to High.

Measured FPS Breakdown

At 1920x1080, the measured average FPS across settings is as follows: Low at 192.9, Medium at 172.7, High at 134.4, and Ultra at 132.1. The progression from Low to Ultra shows a steady decline, with the largest single drop occurring between Medium and High (a 38.3 FPS reduction). The difference between High and Ultra is small at 2.3 FPS, indicating that the Ultra preset adds little overhead at this resolution.

At 2560x1440, the average FPS values are: Low at 160.2, Medium at 122.7, High at 94.3, and Ultra at 91.0. The drop from Low to Medium is 37.5 FPS, and from Medium to High is 28.4 FPS. The gap between High and Ultra narrows to 3.3 FPS, similar to the 1080p pattern. This consistency suggests that the Ultra preset’s additional effects have a fixed cost that does not scale significantly with resolution.

At 3840x2160, the averages are: Low at 92.5, Medium at 72.9, High at 57.6, and Ultra at 54.4. The decline from Low to Medium is 19.6 FPS, from Medium to High is 15.3 FPS, and from High to Ultra is 3.2 FPS. The 4K data shows the same relative behavior as lower resolutions, but the absolute frame rates are much lower. The High to Ultra difference remains minimal, reinforcing that the Ultra preset is not the primary cost; rather, the resolution itself is the dominant factor. The data across all resolutions shows that the RX 6800 XT handles the Ultra preset with only a minor penalty compared to High, making it a viable choice for users who prioritize visual quality.
