Thief

The Intel Core i5-14600K paired with the NVIDIA GeForce RTX 5080 delivers a dramatic range of performance in Thief, scaling from exceptionally high refresh rates at 1080p to more demanding, still-playable frame rates at 4K. The data reveals a system that is heavily GPU-bound at higher resolutions, while the CPU's strong single-threaded performance helps maintain impressive triple-digit frame rates at lower settings.

Resolution Scaling

The measured FPS data for this combo shows a clear and predictable pattern of performance degradation as resolution increases, but the magnitude of that drop varies significantly based on the graphics settings selected. At Ultra settings, the transition from 1920x1080 to 2560x1440 results in a frame rate decrease from 171.5 FPS to 131.1 FPS, a drop of roughly 40 FPS. Pushing further to 3840x2160 at Ultra yields 78.4 FPS, which is less than half of the 1080p result. This steep decline indicates that at 4K Ultra, the RTX 5080's rendering workload becomes the primary limiting factor, with the 14-core CPU providing ample headroom.

The scaling pattern shifts when examining the Low settings preset. At 1920x1080 Low, the combo achieves 206.4 FPS, and this only falls to 184 FPS at 2560x1440. Even at 4K Low, the system maintains 141.5 FPS. The relatively small performance penalty between 1080p and 1440p at Low settings suggests that the CPU and GPU are both contributing to the result, but the system is still capable of feeding the GPU effectively. The most interesting data point appears when comparing the High and Ultra presets at 4K: High produces 78.6 FPS while Ultra produces 78.4 FPS, a negligible difference of 0.2 FPS. This near-identical result at the highest resolution suggests that the game's Ultra preset at 4K is hitting a hard performance ceiling, likely related to the GPU's compute or memory subsystem limits rather than the settings themselves.

The Medium preset at 4K achieves 105.8 FPS, which sits comfortably between the Low and High results. The overall scaling from 1080p to 4K at Medium shows a 45% reduction in frame rate, from 191.9 FPS down to 105.8 FPS. This indicates that the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are sufficient for the game's demands, and the bottleneck is primarily the GPU's shading and rasterization throughput. The data consistently shows that higher resolutions amplify the GPU's role, while lower resolutions allow the CPU's capabilities to shine through.

GPU Role

The NVIDIA GeForce RTX 5080, built on the Blackwell 2.0 architecture, plays the dominant role in shaping Thief's performance at higher resolutions. The GPU's 16 GB of GDDR7 memory across a 256-bit bus provides 960.0 GB/s of bandwidth, which appears more than adequate for this 2014 title, as evidenced by the minimal performance delta between High and Ultra at 4K. The card's boost clock of 2617 MHz and base clock of 2295 MHz are key contributors to the raw throughput, allowing the 10752 shading units to process the game's geometry and lighting effects efficiently.

The GPU's 89th percentile ranking among all tested GPUs, based on its average benchmark score of 59188, positions it as a high-end part. In the context of Thief, the RTX 5080's nearest rivals in average benchmark score include the Intel Arc A570M at 58239 (1.6% lower) and the Intel Arc Pro A60 at 60326 (1.9% higher). This competitive positioning matters because the performance differences seen in the measured FPS data are primarily a function of the GPU's architectural efficiency at different settings. The 56.28 TFLOPS of FP32 compute power is the likely reason the card can push past 200 FPS at 1080p Low, where the game's older DirectX 12 Ultimate (12_2) rendering pipeline is less demanding.

At 4K Ultra, the RTX 5080's 112 ROPs and 879.3 GTexel/s texture rate are what keep the frame rate above 78 FPS. The 84 RT cores, while not necessarily utilized by this game, contribute to the card's overall feature set and DirectX 12 Ultimate support. The GPU's 360 W TDP and dual-slot design indicate a high-power part, but the measured results show that this power translates directly into frame rate headroom at every resolution tested. The card's performance in Thief reflects its position in the broader GPU landscape, where it sits in the 89th percentile, comfortably ahead of most competing parts but with some rivals like the Intel Arc Pro A60 slightly outpacing it in synthetic benchmarks.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the combo demonstrates its peak capability: Low settings achieve 206.4 FPS, Medium hits 191.9 FPS, High reaches 171 FPS, and Ultra delivers 171.5 FPS. The minimal difference between High and Ultra at 1080p (0.5 FPS) mirrors the pattern seen at 4K, suggesting that the game's Ultra preset offers no additional visual benefit beyond High for this hardware.

Moving to 2560x1440, the frame rates remain robust but show the expected decline. Low settings produce 184 FPS, a 22.4 FPS drop from 1080p. Medium achieves 166.1 FPS, while High falls to 139.5 FPS and Ultra to 131.1 FPS. The gap between Medium and High at 1440p is 26.6 FPS, which is larger than the 20.9 FPS gap at 1080p, indicating that the higher resolution amplifies the cost of the High preset's additional effects.

At 3840x2160, the performance scales down further. Low settings maintain 141.5 FPS, which is still highly playable and demonstrates the GPU's headroom even at 4K. Medium produces 105.8 FPS, while High and Ultra yield 78.6 FPS and 78.4 FPS, respectively. The consistency between High and Ultra at 4K, with a spread of only 0.2 FPS, is the most notable data point. This suggests that the Ultra preset's additional rendering features do not meaningfully tax the RTX 5080 beyond what High already requires, or that the system is constrained by another factor such as draw call throughput or memory latency.

The complete dataset shows a monotonic decrease in performance with both increasing resolution and increasing settings quality. The largest single-step drop occurs between 1440p Medium (166.1 FPS) and 4K Medium (105.8 FPS), a 60.3 FPS decrease, while the smallest drop is between 1080p High (171 FPS) and 1080p Ultra (171.5 FPS), which actually shows a slight increase of 0.5 FPS, likely within measurement variance.
