Thief

The Intel Core i5-14400F and AMD Radeon RX 9070 XT combination delivers a performance curve in Thief that is heavily dictated by resolution, with the GPU taking on an increasingly dominant role as pixel count rises. At 1920x1080, the system is clearly capable of pushing frame rates well beyond the bounds of typical high-refresh monitors, but the scaling pattern reveals where the bottlenecks lie. Moving from 1080p to 1440p at High settings, the average frame rate drops from 147 FPS to 101 FPS, a reduction of roughly 31%. This significant dip indicates that the graphics card is already becoming a limiting factor at 1440p, despite the CPU’s strong single-threaded performance. The trend accelerates at 4K, where the High preset yields just 59 FPS, a 60% drop from the 1080p result. This steep decline is a classic sign of a GPU-bound scenario, where the Radeon RX 9070 XT’s raw throughput is the primary determinant of performance.

The data suggests that at 1080p, the system is balanced enough that the CPU can still flex its muscles. The 182 FPS at Low settings at 1080p represents the ceiling of what this combo can achieve in Thief, indicating that even the Core i5-14400F’s 10 cores and 16 threads are sufficient to feed the GPU at this resolution. However, the gap between Low and Ultra at 1080p is 42 FPS, which is substantial but narrower than the 46 FPS gap seen at 1440p between the same settings. This compression at higher resolutions further confirms that the GPU is the primary constraint. At 4K, the difference between Low and Ultra is also 46 FPS, but the absolute numbers are much lower, with the Ultra preset dipping to 56 FPS. This pattern strongly suggests that while the CPU is not a bottleneck at 1080p, its headroom becomes less relevant as the resolution increases, and the RX 9070 XT’s performance ceiling becomes the sole arbiter of playability.

Resolution Scaling

The frame rate scaling from 1080p to 4K paints a clear picture of a system that is balanced at lower resolutions but becomes unequivocally GPU-limited at 4K. At 1080p, the High preset delivers 147 FPS, which is a strong result for a stealth title where fluid motion is crucial for observing enemy patterns. Stepping up to 1440p, the same preset yields 101 FPS, a 46 FPS reduction. This is a substantial penalty, but the result remains highly playable, especially for a game from 2014. The most dramatic shift occurs when moving to 4K, where the High preset falls to 59 FPS. This 42 FPS drop from 1440p represents a 42% performance loss, underscoring that the RX 9070 XT is working at its limits with the increased pixel count.

Looking at the Medium preset, which includes frame time data, the scaling is equally telling. At 1080p, the system averages 165 FPS with a minimum of 140 FPS, showing excellent stability. At 1440p, the average drops to 132 FPS with a minimum of 112 FPS, still very smooth. However, at 4K, the Medium preset averages 78 FPS with a minimum of 66 FPS. The 66 FPS minimum at 4K is the first sign of potential stutter in demanding scenes, suggesting that the GPU is hitting its memory bandwidth limits or shader processing capacity. The fact that the 4K Medium result (78 FPS) is lower than the 1440p High result (101 FPS) confirms that resolution scaling is not linear and that the GPU’s 16 GB of VRAM and 644.6 GB/s bandwidth are being taxed heavily at 4K. The data indicates that for a locked 60 FPS experience at 4K, players must stick to the High preset, as the Ultra preset’s 56 FPS average falls just below that threshold.

The scaling behavior also reveals that the CPU is not a limiting factor until very high frame rates. The jump from 1080p High (147 FPS) to 1080p Low (182 FPS) shows that the i5-14400F can support a 35 FPS increase when the GPU load is reduced. This headroom suggests that for competitive play or high-refresh displays, the CPU can keep pace. However, at 4K, the difference between Low and High is only 43 FPS (102 vs. 59), which is proportionally smaller. This is because the GPU is so heavily loaded that reducing settings has diminishing returns on frame rate, as the bottleneck shifts entirely to the Radeon RX 9070 XT’s compute units.

Settings Recommendations

The measured data provides a clear hierarchy for optimal settings, balancing visual fidelity against frame rate stability. For players targeting 60 FPS at 4K, the High preset is the sweet spot, delivering 59 FPS on average. The Ultra preset is technically not viable for a consistent 60 FPS experience, as it averages 56 FPS, which could lead to noticeable frame pacing issues on a standard 60 Hz display. The Medium preset at 4K offers a more comfortable margin with 78 FPS, but the visual downgrade from High is often unnecessary for a game like Thief, where atmospheric lighting and shadow detail are critical for stealth gameplay. Therefore, for 4K users, High is the recommended preset, as it provides the best visual experience while remaining just within the bounds of playable frame rates.

At 1440p, the choice is more flexible. The Ultra preset averages 96 FPS, which is excellent for high-refresh monitors, and the High preset at 101 FPS is nearly identical in performance. The data shows that the difference between Ultra and High at 1440p is only 5 FPS, making Ultra the obvious choice for those with a 144 Hz or higher display. The Medium preset at 1440p yields 132 FPS, which could be preferred by competitive players seeking maximum responsiveness, but the visual compromise is significant given the small performance gap to Ultra. For 1080p users, the situation is even more straightforward. The Ultra preset averages 140 FPS, which is above the refresh rate of most 144 Hz monitors, and the High preset (147 FPS) is only marginally faster. Given that the game is from 2014 and the hardware is modern, running Ultra at 1080p is the recommended path, as there is no meaningful performance sacrifice for the highest fidelity settings.

The data also reveals that the Low preset is rarely the best choice. At 1080p, it offers 182 FPS, but the visual degradation is severe and unnecessary when Ultra provides 140 FPS. The only scenario where Low might be considered is at 4K for players who prioritize frame rate over everything else, as it delivers 102 FPS, a significant jump from the High preset’s 59 FPS. However, this comes at the cost of the game’s visual identity, which relies heavily on shadow and lighting effects for its stealth mechanics. For most users, the Medium preset at 4K (78 FPS) offers a better balance of playability and visual quality than Low, as it maintains some level of graphical fidelity while staying above the 60 FPS threshold.

GPU Role

The AMD Radeon RX 9070 XT is the clear workhorse in this configuration for Thief, and its specifications align with the observed performance at higher resolutions. The GPU is built on the RDNA 4.0 architecture with a Navi 48 chip, featuring 4096 shading units and 128 ROPs. Its boost clock of 2970 MHz and game clock of 2400 MHz provide substantial compute power, translating to a FP32 performance of 48.66 TFLOPS. This raw throughput is what drives the 4K results, where the GPU is fully saturated. The 16 GB of GDDR6 memory on a 256-bit bus provides a bandwidth of 644.6 GB/s, which is crucial for the high-resolution textures and complex scenes in Thief. The data shows that at 4K, the Medium preset’s minimum FPS of 66 suggests that memory bandwidth is being utilized heavily, but the 16 GB capacity is not a limiting factor, as the game’s VRAM footprint is likely well below this threshold.

The GPU’s performance percentile of 55 against all GPUs is modest when considering its position in the Radeon RX 9000 series, but this is a reflection of the benchmark suite rather than its in-game performance. In Thief specifically, the RX 9070 XT demonstrates its capability by maintaining playable frame rates at 4K Ultra, which is a demanding task for any graphics card. The nearest rivals in the synthetic benchmarks, such as the AMD Radeon HD 7770M and NVIDIA GeForce GTX 570, have significantly older architectures and far lower average scores, but the RX 9070 XT’s delta of just 0.1% to 1% in these synthetic tests is misleading. In actual gaming workloads, the RDNA 4.0 architecture’s modern feature set, including DirectX 12 Ultimate support, provides a clear advantage over those older parts. The GPU’s 128 ROPs are particularly relevant for a game like Thief, which relies on pixel-heavy effects like soft shadows and volumetric lighting, and the data suggests that the ROP throughput is sufficient to handle these effects at 4K without catastrophic frame rate drops.

The GPU’s clock behavior also plays a role in the scaling. The boost clock of 2970 MHz is indicative of the card’s ability to sustain high frequencies under load, which is evident in the 1080p results where the GPU is less stressed. At 1080p Low, the 182 FPS result suggests that the GPU is not the bottleneck, and the CPU is providing the necessary instructions to keep the card fed. However, as resolution increases, the GPU’s compute load becomes the primary factor, and the frame rates scale accordingly. The pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s are high figures that support the 4K performance, but the data shows that even with these specs, the Ultra preset at 4K (56 FPS) pushes the card to its limits. This indicates that for players seeking higher frame rates at 4K, reducing settings to High is a more effective strategy than relying on the GPU’s raw power alone.

How This Combo Ranks

The Intel Core i5-14400F and AMD Radeon RX 9070 XT combination ranks 815th out of 3720 tested combos in Thief, placing it in the top 22% of all systems tested. This is a strong performance, especially considering the game’s age and the hardware’s modern architecture. The ranking reflects the system’s ability to maintain high frame rates across all resolutions, with the 1440p results being particularly impressive. The fact that this combo achieves a 96 FPS average at 1440p Ultra places it well above the median system, which is likely constrained by older GPU architectures. The CPU’s percentile of 83 against all CPUs and the GPU’s percentile of 55 against all GPUs indicate that the processor is a relative strength, but the GPU’s raw performance in Thief is what drives the ranking.

The ranking also highlights the balance between the components. The i5-14400F’s 10 cores and 16 threads, with a boost clock of 4.70 GHz, provide ample processing power for the game’s AI and physics, but the RX 9070 XT’s 48.66 TFLOPS of FP32 performance is the primary driver of the high frame rates. In the context of the nearest rival systems, the combo’s performance is notably better than what the synthetic benchmarks would suggest. While the GPU’s nearest rivals in synthetic tests (like the GTX 570) have significantly lower average scores, the RX 9070 XT’s modern architecture and higher memory bandwidth give it a clear advantage in actual gameplay. The combo’s rank of 815 out of 3720 means that it outperforms the vast majority of systems, which reflects the synergy between the 14th-gen Intel CPU and the RDNA 4.0 GPU.

The ranking also reflects the system’s versatility. At 1080p, the combo is capable of delivering 182 FPS at Low settings, which is more than enough for any competitive scenario. At 4K, it can still manage 59 FPS at High settings, making it a viable 4K gaming system for titles that are not overly demanding. This range of performance is what pushes the combo into the top quartile of tested systems. The data indicates that for a stealth game like Thief, which benefits from high frame rates for smooth camera movement and precise timing, this combo provides an excellent experience without requiring any compromises at 1440p.

CPU Role

The Intel Core i5-14400F plays a supporting role in this configuration, but its specifications are more than adequate for Thief’s demands. The CPU features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. This hybrid design, which combines performance and efficiency cores, is well-suited for a game that relies on single-threaded performance for its core logic. The CPU’s Cinebench R23 single-core score of 3055 and multi-core score of 21645 indicate that it has strong single-threaded capabilities, which are crucial for maintaining high frame rates at lower resolutions. The data supports this, as the 1080p Low result of 182 FPS shows that the CPU is not a bottleneck when the GPU load is minimized.

The CPU’s 20 MB of shared L3 cache and 1.25 MB of L2 cache per core provide adequate memory bandwidth for the game’s data access patterns. The dual-channel memory bus, supporting both DDR4 and DDR5, allows for flexible system configuration, though the exact memory speed is not specified in the data. In Thief, the CPU’s role is primarily to handle the game’s AI routines and physics calculations, which are not excessively demanding for a 2014 title. The benchmark results show that the CPU’s performance is within 0.5% of its nearest rivals, such as the Intel Core i9-11900 and AMD Ryzen 7 6800HS, indicating that it is a well-rounded processor for gaming.

However, the CPU’s influence on frame rates diminishes as resolution increases. At 4K, the difference between the Low and Ultra presets is 46 FPS, which is identical to the difference at 1440p. This suggests that the CPU is not the limiting factor at higher resolutions, as the GPU’s workload becomes the dominant constraint. The CPU’s 65W TDP and Intel Socket 1700 compatibility make it an easy component to cool and integrate, but these are qualitative aspects that do not directly impact the measured frame rates. The data indicates that for Thief, the i5-14400F provides sufficient headroom to avoid bottlenecking the RX 9070 XT at 1080p and 1440p, but it is not the primary driver of performance at 4K. This is a well-balanced pairing for a game that is more GPU-intensive at higher resolutions.
