Thief

The Core i5-13400F paired with the GeForce RTX 3080 delivers a decisive 1080p experience in Thief, with the measured data showing average framerates that comfortably exceed high-refresh targets. At 1440p, the combination remains potent, while 4K transitions from playable to demanding depending on the graphics preset. The data, drawn from measured benchmarks, indicates a system that scales predictably with resolution and settings, with the CPU holding a firm lead at lower resolutions and the GPU becoming increasingly relevant as pixel count rises.

Settings Recommendations

The measured FPS data provides a clear hierarchy for settings across the three resolutions tested. At 1920x1080, all four presets deliver smooth, well-above-60 FPS averages, with the Low preset hitting 178 FPS, Medium at 161 FPS, High at 141 FPS, and Ultra at 134 FPS. Given the narrow gap between High and Ultra (just 7 FPS), Ultra is the best experience at 1080p; it offers maximum quality with an average FPS of 134, which is still far above what any 60 Hz display needs, and only a 47 FPS difference from the Low preset. The measured Medium preset at 1080p shows a minimum FPS of 137 and a maximum of 186, indicating consistent performance for this setting.

At 2560x1440, the data shows a more pronounced impact from settings. The Ultra preset yields an average of 92 FPS, High produces 97 FPS, Medium 127 FPS, and Low 157 FPS. The 5 FPS difference between High and Ultra is the smallest gap in the resolution, at just 5 FPS, but the 30 FPS jump from High to Medium is significant. For the best experience at 1440p, the Medium preset delivers 127 FPS average with a minimum of 108 FPS and maximum of 146 FPS, providing a comfortable margin above 60 FPS and leaving headroom for other tasks. Users prioritizing the highest visual fidelity can still choose the Ultra preset, as the 92 FPS average remains a solid result, but Medium offers the most balanced experience, with High as a slightly more demanding alternative.

At 3840x2160, the situation changes. The Low preset reaches an average of 98 FPS, Medium 75 FPS, High 57 FPS, and Ultra 54 FPS. The Medium preset is the only one with both an average above 60 FPS and a recorded minimum (63 FPS) that stays above that threshold. High and Ultra dip below 60 FPS, with averages of 57 and 54 FPS, respectively. For 4K, the Medium preset is the recommended choice, as it is the only setting that maintains a minimum FPS above 60. The Low preset offers a much higher average (98 FPS), but the 23 FPS jump from Medium to Low suggests that Low sacrifices significant visual, potentially for those who require a higher refresh rate at 4K. The data indicates that 4K is the only resolution where settings choices have a dramatic effect on maintaining a stable 60 FPS experience; the difference between Low and Ultra is 44 FPS.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor from the Raptor Lake-S family, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. It is built on a 10 nm process and has a 65 W TDP. The processor features an L3 cache of 20 MB shared. The benchmark data

for this CPU shows strong multithreaded performance: it scores 22,604 points in Cinebench R23 multicore, 8,892 in R20 multicore, and 2,278 in R15 multicore. Single-thread performance is 3,191 in Cinebench R23 and 1,255 in R20. The CPU’s overall benchmark percentile places it at 77, meaning it outperforms 77% of all CPUs in the database.

In Thief, the CPU's impact is particularly noticeable at 1080p, where the GPU is less likely to be the bottleneck. The data shows that at 1920x1080 with Low settings, the average FPS is 178, which is 20 FPS higher than the Low preset at 1440p (157 FPS) and 80 FPS higher than the Low preset at 4K (98 FPS). This suggests that the CPU is capable of driving very high frame rates, but the GPU begins to limit performance as resolution increases. The CPU’s boost clock of 4.60 GHz and 10 cores with a 20 MB L3 cache contribute to this high single-thread performance, which is essential for the game’s simulation and logic.

The CPU's 3DMark benchmark scores provide additional context. The single-thread score of 960 and the 2-thread score of 1880 indicate strong per-core performance. In contrast, the 16-thread score of 7,314 is only slightly higher than the 8-thread score of 5,591, suggesting that Thief likely does not fully utilize all 16 threads, but the CPU’s strong single-thread performance is a key factor in maintaining high average FPS at lower resolutions. The data shows that the CPU's role is to feed the GPU enough frames; at 1440p and 4K, the gap between Low and Medium settings (30 FPS and 23 FPS, respectively) are likely due to GPU load, while at 1080p, the difference between Low and Medium is only 17 FPS, indicating that the CPU is less of a limiting factor at that resolution.

The Core i5-13400F’s performance in Thief, as measured, demonstrates that it is sufficiently powerful to avoid bottlenecking the RTX 3080 at 1080p. However, the measured FPS at higher resolutions show a clear GPU bottleneck, as the CPU’s influence diminishes when pixel count increases. The CPU upgrade path would not significantly change the gameplay experience at 1440p or 4K, where the GPU is the primary constraint.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end GPU with a GA102 chip built on a 8 nm process. It has a base clock of 1440 MHz and a boost clock of 1710 MHz. The card features 10 GB of GDDR6X memory on a 320-bit bus, delivering a memory bandwidth of 760.3 GB/s. It also boasts 8,704 shading units, 272 TMUs, and 96 ROPs, with a pixel rate of 164.2 GPixel/s and a texture rate of 465.1 GTexel/s. The card’s FP32 performance is 29.77 TFLOPS. Its average benchmark score is 23,172, placing it in the 68th percentile of all GPUs. The RTX 3080's nearest rivals are the NVIDIA P106-100 (with a delta of -0.3%), AMD Radeon Pro Vega 16 (-0.3%), and AMD Radeon RX 6600M (-0.4%), indicating that the RTX 3080 is in a close performance group.

In Thief, the GPU's role is most evident in the resolution scaling. At 1080p, the average FPS is 141 on High, but at 1440p it drops to 97, and at 4K it falls to 57. This represents a 31% drop from 1080p to 1440p and another 41% drop from 1440p to 4K, when using the High preset. The Low preset shows a similar trend: 178 FPS at 1080p, 157 FPS at 1440p, and 98 FPS at 4K. These figures show that the GPU is heavily stressed at 4K, with the average FPS falling below the 60 FPS threshold for High settings.

The RTX 3080’s 10 GB of VRAM is sufficient for Thief at the tested resolutions, as the game is a 2014 title and does not have the high VRAM requirements of modern AAA titles. The memory bandwidth of 760.3 GB/s ensures that the GPU can handle the texture and geometric data at high resolutions. The card’s 272 TMUs and 96 ROPs are also sufficient for the game’s rendering, with the High preset at 1440p producing an average of 97 FPS.

The GPU’s performance relative to its nearest rivals is close, with the RTX 3080 sitting in a cluster with the AMD Radeon RX 6600M. The benchmark scores show a delta of only -0.4% against the RX 6600M, meaning the RTX 3080 is just above the average score of that rival. In-game, this translates to a similar level of performance, but the RTX 3080's 10 GB VRAM and higher memory bandwidth give it an edge at 4K. The data indicates that the GPU is a balanced performer, but its 4K performance is the limiting factor in this configuration, as the CPU can maintain high frame rates at lower resolutions.

Resolution Scaling

The measured FPS data for the Core i5-13400F + RTX 3080 combination shows clear resolution scaling behavior. Across all four settings presets, the FPS drops as resolution increases from 1920x1080 to 2560x1440 and then to 3840x2160. The High preset, for example, goes from 141 FPS at 1080p to 97 FPS at 1440p, a 44 FPS drop, and then to 57 FPS at 4K, a 40 FPS drop. The Low preset drops from 178 FPS to 157 FPS to 98 FPS, respectively. The Medium preset shows a similar pattern: 161 FPS at 1080p, 127 FPS at 1440p, and 75 FPS at 4K. The Ultra preset goes from 134 FPS at 1080p to 92 FPS at 1440p to 54 FPS at 4K.

This scaling indicates that the GPU is the primary limiting component at higher resolutions. The FPS drop from 1440p to 4K is more severe than the drop from 1080p to 1440p, suggesting that the GPU’s pixel and texture throughput is a key constraint at 4K. The RTX 3080’s pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s are substantial, but the 4K resolution roughly quadruples the pixel workload compared to 1080p, which explains the significant FPS drop.

Conversely, the CPU is more of a limiting factor at 1080p, where the GPU has less pixel work. The Low preset at 1080p achieves 120 FPS, which is only 20 FPS lower than the Low preset at 1440p (100 FPS), indicating that the CPU is still capable of high frame rates. However, the gap between Low and Medium at 1080p is 17 FPS, while at 1440p it is 30 FPS, and at 4K it is 23 FPS, showing that the GPU’s role in limiting performance grows with resolution. The data suggests that at 1080p, the CPU is sufficient to drive the GPU, but at 4K, the GPU is the clear bottleneck.
