Thief

The Intel Core i5-14400F and AMD Radeon RX 5700 XT combination delivers a playable but resolution-sensitive experience in Thief, with the GPU acting as the primary performance limiter at higher settings. The data shows a clear pattern: frame rates scale inversely with resolution and preset quality, but the scaling curve reveals that the RX 5700 XT is the component holding this combo back at 4K, while the i5-14400F provides ample headroom at lower resolutions.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the magnitude of the drop varies significantly depending on the preset. At 1080p High settings, this combo averages 88 FPS, which drops to 60 FPS at 1440p (a 31.8% reduction) and further to 35 FPS at 4K (a 60.2% reduction from 1080p). This scaling pattern strongly suggests that the RX 5700 XT's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are being saturated as pixel count increases, particularly at the 4K resolution where the GPU's 256-bit memory bus and 9.754 TFLOPS of FP32 compute are insufficient to maintain high frame rates.

The Low preset tells a different story. At 1080p Low, the combo achieves 152 FPS, which drops to 104 FPS at 1440p (31.6% reduction) and 61 FPS at 4K (59.9% reduction from 1080p). The consistent percentage drops across presets—roughly 32% from 1080p to 1440p and 60% from 1080p to 4K—indicate that resolution scaling is the dominant factor, not preset complexity. This is characteristic of a GPU-bound scenario where the RX 5700 XT's pixel fill rate of 121.9 GPixel/s becomes the bottleneck at higher resolutions.

The Medium preset provides the most granular data, with min and max FPS recorded at every resolution. At 1080p Medium, the combo delivers 115 FPS average with a minimum of 98 FPS and maximum of 133 FPS. At 1440p Medium, the average drops to 79 FPS with a minimum of 67 FPS and maximum of 91 FPS. At 4K Medium, the average falls to 47 FPS with a minimum of 40 FPS and maximum of 54 FPS. The min-to-max variance remains consistent at roughly 30% across all resolutions, suggesting stable frame pacing rather than sudden spikes or drops.

The transition from Medium to High at 4K is particularly telling: Medium averages 47 FPS while High averages 35 FPS, a 25.5% penalty for the quality increase. This indicates that the RX 5700 XT has very little headroom at 4K, and any increase in shading complexity or texture detail directly impacts performance. At 1080p, the High-to-Ultra transition costs 4 FPS (88 to 84), but at 4K, the same transition costs only 1 FPS (35 to 34), showing that the GPU is already so saturated at 4K High that Ultra settings add negligible additional load—the bottleneck is the GPU's raw throughput, not the specific preset features.

How This Combo Ranks

This specific combination of the Intel Core i5-14400F and AMD Radeon RX 5700 XT ranks 2731 out of 3720 tested combos in Thief, placing it in the bottom 26.6% of all configurations. This relatively low ranking is surprising given the individual components' benchmark scores, suggesting that the game's engine is particularly demanding on the GPU subsystem rather than CPU throughput.

The i5-14400F itself performs admirably in synthetic benchmarks, with an average benchmark score of 32279 and a percentile ranking of 83 among all CPUs. Its nearest rivals include the AMD Ryzen 7 PRO 8840U (avg score 32233, deltaPct 0.1), Intel Core i9-11900 (avg score 32226, deltaPct 0.2), and AMD Ryzen 7 6800HS (avg score 32354, deltaPct -0.2). The CPU's Cinebench R23 multicore score of 21645 and single-core score of 3055 demonstrate strong processing capability that should not bottleneck most games.

Meanwhile, the RX 5700 XT has an average benchmark score of 16361 and ranks in the 59th percentile among all GPUs. Its nearest rivals are the AMD Radeon Pro 5600M (avg score 16351, deltaPct 0.1), NVIDIA RTX PRO 6000 Blackwell (avg score 16408, deltaPct -0.3), and AMD Radeon PRO W7500 (avg score 16415, deltaPct -0.3). The GPU's 3DMark Steel Nomad DX12 score of 2134 and Passmark G3D score of 16277 are respectable but not exceptional, placing it in the mid-range tier.

The combination's low rank in Thief specifically, despite both components having near-average or above-average benchmark scores, indicates that this game is particularly sensitive to the RX 5700 XT's architectural limitations. The RDNA 1.0 architecture, while efficient at 7 nm, lacks the raw compute density of newer designs, and the 8 GB VRAM capacity becomes a constraint at higher resolutions and settings.

GPU Role

The AMD Radeon RX 5700 XT is the clear limiting factor in this combination for Thief. Its 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which is sufficient for 1080p gameplay but becomes strained at 1440p and especially 4K. The GPU's boost clock of 1905 MHz and game clock of 1755 MHz (with a base clock of 1605 MHz) allow it to reach 9.754 TFLOPS of FP32 performance, but this is simply not enough to maintain 60 FPS at 4K Ultra, where the combo averages only 34 FPS.

The memory subsystem is particularly relevant in Thief, a game from 2014 with relatively modest VRAM requirements. At 1080p, the 8 GB capacity is more than sufficient, evidenced by the 152 FPS Low and 84 FPS Ultra results. However, at 4K, the texture bandwidth demands increase substantially, and the RX 5700 XT's 448.0 GB/s becomes a bottleneck. The 14 Gbps effective memory speed (1750 MHz memory clock) is competitive for its generation but trails newer GPUs with higher bandwidth.

The GPU's 2560 shading units, 160 texture mapping units, and 64 raster output pipelines deliver a texture rate of 304.8 GTexel/s and pixel rate of 121.9 GPixel/s. These specifications explain the 4K performance: the pixel rate is insufficient to fill 8.3 million pixels per frame at high frame rates. The RDNA 1.0 architecture's compute capabilities, while strong for its time, show their age in this workload. The Passmark DirectX 11 score of 116 and DirectX 12 score of 64 highlight that the GPU is better suited to older APIs, which aligns with Thief's 2014 release date and its likely DirectX 11 rendering path.

The GPU's thermal and power characteristics—225 W TDP with a dual-slot cooler and 1x 6-pin + 1x 8-pin power connectors—suggest it can sustain boost clocks under load, but the measured performance indicates that architectural limits, not thermal throttling, are the constraint.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combination depend heavily on the target resolution and desired frame rate. For 60 FPS gameplay, the data shows that only 1080p and 1440p can achieve this target, and only at certain presets.

At 1080p, the High preset delivers 88 FPS, which is well above the 60 FPS target and provides a good balance of visual quality and performance. The Ultra preset at 1080p yields 84 FPS, a mere 4 FPS penalty for maximum quality, making it the recommended choice for users with 1080p displays who want the best visual experience without sacrificing smoothness. The Medium preset at 115 FPS and Low at 152 FPS are available for users with high-refresh-rate monitors, but the visual quality trade-off is significant.

At 1440p, the High preset achieves exactly 60 FPS, making it the minimum viable option for smooth gameplay at this resolution. The Ultra preset drops to 57 FPS, which is borderline but may be acceptable for users who prioritize visual fidelity over a perfect 60 FPS lock. The Medium preset at 79 FPS is the sweet spot for 1440p, offering a comfortable margin above 60 FPS while retaining moderate visual quality.

At 4K, none of the presets achieve 60 FPS. The Low preset averages 61 FPS, barely crossing the threshold, but the visual quality at Low is likely unacceptable for most users. The Medium preset at 47 FPS is the highest quality option that remains playable, though users will need to tolerate frame rates in the 40-54 FPS range. The High preset at 35 FPS and Ultra at 34 FPS are not recommended for 4K, as the frame rates fall below the generally accepted playability threshold.

For users with variable refresh rate displays, the Medium preset at 1440p (79 FPS average, 67-91 FPS range) or Medium at 1080p (115 FPS average, 98-133 FPS range) provides the most consistent experience with the least frame-time variance. The data suggests that Medium settings offer the best balance of visual quality and performance across all resolutions, with the 1440p Medium configuration being the most versatile choice for this hardware combination.

CPU Role

The Intel Core i5-14400F plays a supporting role in this combination, providing more than enough processing power for Thief's requirements. With 10 cores and 16 threads, the CPU offers substantial multi-threaded capability, evidenced by its Cinebench R23 multicore score of 21645 and Passmark multithread score of 25470. The boost clock of 4.70 GHz (base 2.50 GHz) delivers strong single-threaded performance, with a Geekbench single-core score of 2058 and Cinebench R23 single-core score of 3055.

The CPU's architecture, Raptor Lake-R on a 10 nm process, provides efficient instruction handling. Its Passmark data compression score of 315521 and data encryption score of 16949 indicate robust integer performance, while the floating-point math score of 61319 shows strong FPU capability. These characteristics make the i5-14400F well-suited for handling game logic, physics calculations, and AI routines in Thief, which is a stealth game that typically requires moderate CPU resources.

The 20 MB of shared L3 cache and 1.25 MB per-core L2 cache (with 80 KB per-core L1) provide ample data locality for game workloads. The CPU's 83rd percentile ranking among all CPUs, with an average benchmark score of 32279, places it well above the median. Its nearest rival, the AMD Ryzen 7 PRO 8840U, scores nearly identically (32233, deltaPct 0.1), while the Intel Core i9-11900 (32226, deltaPct 0.2) and AMD Ryzen 7 6800HS (32354, deltaPct -0.2) bracket its performance.

The evidence that the CPU is not the bottleneck comes from the resolution scaling pattern. If the CPU were limiting performance, frame rates would remain similar across resolutions. Instead, the data shows a consistent 60% reduction from 1080p to 4K across all presets, which is the signature of a GPU-bound scenario. The CPU's 65 W TDP and 10 nm process node ensure it can maintain boost clocks without thermal throttling, further supporting its role as a reliable foundation for the GPU to perform within its limits.

The i5-14400F's memory support for both DDR4 and DDR5, with dual-channel configuration, provides flexibility for system builders. Its PCIe Gen 5 support with 16 lanes ensures the RX 5700 XT (which uses PCIe 4.0 x16) has ample bandwidth for data transfer. The CPU's 10 cores and 16 threads are more than sufficient for a 2014 game title, meaning the performance ceiling in Thief is determined entirely by the GPU's rendering capabilities, not CPU throughput.
