Thief

Resolution Scaling

The measured frame rates for Thief with the Intel Core i5-14400F and AMD Radeon RX 6800 XT reveal a clear pattern: the GPU is the dominant performance constraint at higher resolutions, while the CPU's headroom becomes visible only at 1080p. Moving from 1920x1080 to 2560x1440 on High settings drops the average from 139 FPS to 95.3 FPS, a reduction of roughly 31%. The jump from 2560x1440 to 3840x2160 is even steeper, falling to 54.7 FPS — a 43% decline from the 1440p figure. This scaling behavior is typical of a GPU-bound scenario at 4K, where pixel throughput becomes the limiting factor.

At Low settings, the resolution scaling tells a slightly different story. The 1080p result of 180.2 FPS drops to 158.3 FPS at 1440p and then to 97.3 FPS at 4K. The 1440p-to-4K drop here is 39%, which is significant but less severe than the High preset's 43% decline. This suggests that even at Low settings, the RX 6800 XT is still doing substantial work at 4K, though the frame rates remain highly playable. The fact that 4K Low (97.3 FPS) outperforms 1080p Ultra (131 FPS) by a wide margin indicates that the GPU has enough headroom to handle reduced settings at high resolution without becoming a bottleneck at lower resolutions.

The Ultra preset shows the most pronounced scaling penalty: 131 FPS at 1080p, 88.4 FPS at 1440p, and 55.3 FPS at 4K. The 1080p-to-4K drop of 58% under Ultra settings demonstrates that the combination of maximum graphical features and 4K resolution pushes the GPU to its limits. Meanwhile, Medium settings scale more gracefully: 166.9 FPS at 1080p, 123.4 FPS at 1440p, and 74.8 FPS at 4K. The data indicates that for users targeting 4K, dropping from Ultra to High yields only a marginal 1 FPS improvement (55.3 vs 54.7), suggesting that Ultra and High are nearly identical in cost at that resolution — a notable anomaly worth considering.

GPU Role

The AMD Radeon RX 6800 XT brings substantial resources to Thief: 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. The GPU's base clock of 1825 MHz boosts to 2250 MHz, with a game clock of 2015 MHz. These specifications position the card in the 87th percentile of all GPUs in the benchmark database, with an average benchmark score of 49982. Its nearest rivals include the Intel Arc A550M (deltaPct 0.5), NVIDIA RTX A1000 (deltaPct -1.7), and NVIDIA CMP 50HX (deltaPct 1.9), showing that the RX 6800 XT sits in a competitive mid-to-high tier.

The 16 GB VRAM capacity is more than sufficient for Thief, a 2014 title that does not require large texture pools. The memory bandwidth of 512.0 GB/s proves ample for the game's asset streaming, as evidenced by the smooth scaling from 1080p to 4K. The GPU's RDNA 2.0 architecture with 4608 shading units and 128 ROPs delivers a pixel rate of 288.0 GPixel/s, which aligns with the 4K performance observed. At 4K Ultra, the 55.3 FPS result shows the GPU is working near its practical limit for this title, but it never falls below 54.7 FPS at High — indicating consistent frame delivery without catastrophic dips.

The GPU's FP32 compute of 20.74 TFLOPS and texture rate of 648.0 GTexel/s are more than adequate for Thief's lighting and shadow calculations. The benchmark scores reinforce this: a Passmark G3D score of 24980 and a 3DMark Steel Nomad DX12 score of 3689. Interestingly, the DirectX 11 Passmark score of 264 is higher than the DirectX 12 score of 100, which may reflect the game's age and its reliance on older API paths. For a stealth game where smooth traversal matters, the RX 6800 XT's 4K performance at Medium (74.8 FPS) and High (54.7 FPS) provides a solid foundation.

How This Combo Ranks

This specific combination of Intel Core i5-14400F and AMD Radeon RX 6800 XT ranks 446th out of 1642 tested combos in Thief, placing it in the upper 27% of all configurations in the database. This is a respectable position, though not elite. The rank reflects a balance where the CPU and GPU are reasonably matched for this title, but neither component is pushing the other to extreme levels.

The combo rank of 446 out of 1642 suggests that there are many faster configurations, likely pairing higher-end CPUs or GPUs with more aggressive settings. However, the measured FPS data shows that this combo delivers strong playable performance across all tested resolutions and settings. At 1080p Ultra, it hits 131 FPS, which is well above the 60 FPS threshold for smooth gameplay. At 1440p Ultra, it manages 88.4 FPS, and even at 4K Ultra, it maintains 55.3 FPS — just shy of 60 but still playable.

The rank's percentile position (roughly 73rd percentile) indicates that the combo outperforms the majority of tested systems, likely due to the RX 6800 XT's strong compute capabilities and the i5-14400F's solid single-thread performance. The CPU's percentileVsAllCpus of 88 and the GPU's percentileVsAllGpus of 87 both point to above-average components individually, and their combined rank reflects that synergy. For a game like Thief, which was released in 2014 and is not overly demanding by modern standards, this combo provides headroom that many lower-ranked configurations lack.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 180.2 FPS, Medium hits 166.9 FPS, High reaches 139 FPS, and Ultra drops to 131 FPS. The gap between Low and Ultra is 49.2 FPS, or 27%, which is modest and indicates that even at maximum settings, the CPU-GPU pair is not severely strained. The 1080p results suggest that the CPU's 10 cores and 16 threads, with a boost clock of 4.70 GHz, are sufficient to feed the GPU without creating a bottleneck at this resolution.

Moving to 2560x1440, the numbers scale down predictably. Low produces 158.3 FPS, Medium 123.4 FPS, High 95.3 FPS, and Ultra 88.4 FPS. The drop from 1080p to 1440p at Low settings is 12%, while at Ultra it is 33%. This widening gap at higher settings confirms that the GPU begins to take on more load as resolution increases. At 1440p, all settings remain above 88 FPS, which is excellent for a stealth title where consistent frame pacing is important for immersion.

At 3840x2160, the performance becomes more varied. Low yields 97.3 FPS, Medium 74.8 FPS, High 54.7 FPS, and Ultra 55.3 FPS. Notably, High and Ultra are nearly identical at 4K, with Ultra actually 0.6 FPS faster than High — a statistical tie within measurement variance. This suggests that at 4K, the GPU's shading resources are saturated, and the extra features in Ultra over High do not add meaningful overhead for this title. The 4K Low result of 97.3 FPS is impressive, showing that the RX 6800 XT can still deliver high refresh rates at 4K when settings are reduced.

CPU Role

The Intel Core i5-14400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. Its L3 cache of 20 MB (shared) and dual-channel DDR4/DDR5 memory support provide adequate bandwidth for gaming workloads. In synthetic benchmarks, the CPU scores 21914 in Cinebench R23 multi-core and 3093 in single-core, with a Passmark multithread score of 25783 and single-thread score of 3723. Its percentileVsAllCpus of 88 indicates strong overall performance.

In Thief, the CPU's role is primarily to maintain frame delivery at high refresh rates, especially at 1080p where the GPU is less stressed. The 180.2 FPS at 1080p Low demonstrates that the i5-14400F can push frames well beyond typical monitor refresh rates. The single-core performance, reflected in the Geekbench single-core score of 2333, is critical for a game that likely has a primary game thread. The boost clock of 4.70 GHz ensures that this thread can execute quickly.

The CPU's nearest rivals in the database include the Intel Core i7-12800H (deltaPct 0), AMD Ryzen 5 PRO 7645 (deltaPct 0.2), and AMD Ryzen 7 250 (deltaPct -0.2). These near-identical scores suggest that the i5-14400F's performance is well within the expected range for its class. For Thief, the CPU's 65 W TDP and 10 nm process node mean it runs efficiently, but the real takeaway is that it does not bottleneck the RX 6800 XT at any resolution tested — the FPS differences between settings are consistent with GPU-bound scaling.

Settings Recommendations

For 1080p users, the data strongly supports Ultra settings. The 131 FPS at Ultra is only 8 FPS lower than High (139 FPS), and both are far above playable thresholds. Given that the game runs at over 130 FPS at maximum settings, there is no reason to compromise visual quality at this resolution. The 49 FPS gap between Low and Ultra is notable, but Ultra's frame rate is still excellent.

At 1440p, Ultra at 88.4 FPS is the best choice for those with 144 Hz monitors, as it remains above 60 FPS and offers the full visual experience. If a player prefers higher refresh rates, High at 95.3 FPS provides a modest 7 FPS improvement with minimal visual cost. Medium at 123.4 FPS is also viable for competitive play, but the visual downgrade from Ultra is significant for a stealth game where atmosphere matters.

At 4K, the recommendation is more nuanced. Ultra (55.3 FPS) and High (54.7 FPS) are nearly identical, so there is no benefit to dropping from Ultra to High. However, Medium at 74.8 FPS offers a substantial 20 FPS improvement over Ultra while still maintaining good visual fidelity. For players prioritizing smooth gameplay at 4K, Medium is the sweet spot. Low at 97.3 FPS is available for those who want high refresh rates at 4K, but the visual compromise is likely too severe for a game that relies on lighting and shadow for its stealth mechanics. The data suggests that 4K Medium provides the best balance of performance and visual quality for this combo.
