Thief

Thief, a 2014 stealth title, remains a demanding benchmark even a decade later, and the combination of the Intel Core Ultra 5 225 and NVIDIA GeForce RTX 3080 Ti produces a compelling dataset. The measured frames per second (FPS) across resolutions and settings reveal a system that is consistently capable, but the performance scaling between presets and pixel counts tells a more nuanced story about where the bottleneck lies. This analysis examines the measured data to determine the optimal settings, the roles of the GPU and CPU, and how this specific pairing ranks against other tested configurations.

Settings Recommendations

The measured data for this combination in Thief clearly indicates that the High preset offers the best balance of visual fidelity and performance across all tested resolutions. At 1920x1080, the High preset delivers an average of 146 FPS, which is a substantial 7 FPS higher than the Ultra preset's 139 FPS. The performance gap widens at higher resolutions, with High achieving 100 FPS at 2560x1440 and 59 FPS at 3840x2160, compared to Ultra's 95 FPS and 56 FPS, respectively. The difference between High and Ultra is minimal in terms of average FPS, but the data suggests that the Ultra preset imposes a measurable cost without a corresponding benefit in the measured metrics.

While the Low preset delivers the highest frame rates—216 FPS at 1080p, 173 FPS at 1440p, and 102 FPS at 4K—it does so by sacrificing the visual quality that the game's stealth and atmosphere rely on. The Medium preset offers a middle ground, with 192 FPS at 1080p, 132 FPS at 1440p, and 77 FPS at 4K, showing a significant jump from Low but still below the High preset's stability. The data for Medium also includes measured minimum and maximum FPS values (e.g., 163-221 at 1080p), which are absent for High and Ultra, suggesting that Medium may exhibit more frame-time variance.

The High preset appears to be the sweet spot, as it provides a frame rate that is 5% higher than Ultra at 1080p and maintains playability at 4K with an average of 59 FPS. For users with high refresh rate monitors at 1080p or 1440p, the High preset's combination of performance and fidelity is the most sensible choice. At 4K, the High preset's 59 FPS is right at the threshold of smooth gameplay, and while the Ultra preset drops to 56 FPS, the difference is unlikely to be perceptible in a stealth game that doesn't require twitch reflexes. The recommendation, based purely on the measured data, is to prioritize the High preset for the best overall experience.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the primary driver of frame rates in this dataset, and its specifications align with the observed performance. The GPU features 12 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 912.4 GB/s. This ample memory capacity and bandwidth are crucial for Thief at higher resolutions, where texture data and geometry can quickly consume video memory. The measured FPS scaling from 1080p to 4K indicates that the GPU is the limiting factor, as the frame rate drops proportionally with the increase in pixel count.

The GPU's architecture, Ampere, is built on an 8 nm process with 28,300 million transistors. Its boost clock of 1665 MHz and a base clock of 1365 MHz are relatively modest, but the sheer number of shading units (10240) and texture mapping units (320) allow for substantial parallel processing power. The FP32 performance of 34.10 TFLOPS explains why the GPU can maintain high frame rates even at 1440p, where the High preset achieves 100 FPS. The data shows that the RTX 3080 Ti has enough raw compute to handle Thief's DirectX 12 workload, but the performance ceiling is reached at 4K Ultra, where the average FPS drops to 56.

The GPU's 12 GB VRAM is a key asset. At 4K with High settings, the GPU averages 59 FPS, indicating that memory capacity is not a bottleneck at this configuration. However, the jump from High to Ultra at 4K results in a 3 FPS drop (from 59 to 56), which could be attributed to increased memory pressure or more complex shader work. The GPU's passmark G3D score of 26896 and its 83rd percentile ranking among all GPUs further solidify its position as a high-end part that can handle demanding titles. The measured results confirm that the RTX 3080 Ti is more than sufficient for Thief, with its performance limited primarily by resolution and settings, not by its own capabilities.

Resolution Scaling

The measured FPS data across 1080p, 1440p, and 4K reveals a clear pattern of performance degradation that is characteristic of a GPU-bound scenario. At the High preset, the average FPS drops from 146 at 1920x1080 to 100 at 2560x1440, a 31.5% decrease, and then to 59 at 3840x2160, a further 41% decrease from the 1440p figure. This scaling is consistent with the increase in pixel count, where 4K has approximately 4 times the pixels of 1080p, requiring significantly more GPU processing power.

The Low preset shows a similar trend, with 216 FPS at 1080p dropping to 173 FPS at 1440p (a 19.9% decrease) and then to 102 FPS at 4K (a 41% decrease). The relative drops are smaller at lower settings because the GPU is not as heavily taxed, but the overall pattern remains. The Medium preset's data, which includes min and max FPS, shows an average of 192 FPS at 1080p, 132 FPS at 1440p, and 77 FPS at 4K. The min FPS values at 1440p (112) and 4K (66) are notably lower than the averages, suggesting that there are moments of increased complexity that cause frame drops.

This scaling indicates that the RTX 3080 Ti is the limiting component in this system. If the CPU were the bottleneck, we would expect to see a plateau in FPS at lower resolutions, where the GPU has more headroom. Instead, the FPS continues to rise dramatically from 4K to 1080p, confirming that the GPU's rendering throughput is the primary constraint. The data implies that for users targeting 4K, the High preset (59 FPS) is the upper limit for smooth gameplay, while 1440p and 1080p offer ample headroom for higher refresh rates.

How This Combo Ranks

In the context of all tested CPU and GPU combinations for Thief, this pairing of Intel Core Ultra 5 225 and NVIDIA GeForce RTX 3080 Ti ranks 436 out of 2851 tested combos. This places it in the top 15.3% of all configurations, which is a strong showing for a system with a mid-range CPU and a previous-generation high-end GPU. The combo's rank of 436 suggests that while it is not the absolute fastest, it outperforms the vast majority of tested systems, likely due to the GPU's substantial compute power.

The CPU's nearest rivals provide context for its contribution to this ranking. The Intel Core Ultra 5 225 has an average benchmark score of 36938, which is nearly identical to the AMD Ryzen 5 5600F (36945), with a delta percentage of 0. The CPU is also within 0.5% of the AMD Ryzen 5 5500X3D (37018) and the Intel Core i9-12900T (37112). This indicates that the CPU's performance is on par with these competitors, and its 85th percentile ranking among all CPUs shows it is a capable mid-range processor. The GPU, with its 83rd percentile ranking, is also a strong performer, but the combo's overall rank is likely driven by the GPU's ability to push high frame rates.

The rank of 436 out of 2851 is notable because it demonstrates that this combination is well-balanced for Thief. The CPU does not hold back the GPU to a significant degree, as evidenced by the high FPS at 1080p (216 FPS on Low), which indicates that the CPU can feed the GPU enough data to reach high frame rates. The data suggests that this combo is a solid choice for Thief, offering performance that is better than the majority of systems, though there is room for improvement with a more powerful CPU or a newer GPU.

CPU Role

The Intel Core Ultra 5 225 plays a supporting role in this combination, but its specifications are sufficient to avoid bottlenecking the RTX 3080 Ti in Thief. The CPU has 10 cores and 10 threads, with a base clock of 3.30 GHz and a boost clock of 4.90 GHz. This core count and clock speed are adequate for a game from 2014, which typically relies more on single-threaded performance and fewer cores. The CPU's cache structure includes 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3 cache, which helps reduce memory latency.

The CPU's benchmark scores support its capability. In Cinebench R23, it scores 25891 in multi-core and 3655 in single-core, showing strong performance in both areas. The PassMark single-thread score of 4412 is particularly relevant for Thief, as the game's engine likely benefits from high single-core performance. The CPU's 85th percentile ranking among all CPUs indicates that it is better than most, and its nearest rivals—the AMD Ryzen 5 5600F and Ryzen 5 5500X3D—have nearly identical average scores, confirming its competitive standing.

In Thief, the CPU's role is to process game logic, physics, and draw calls. The measured FPS at 1080p Low (216 FPS) suggests that the CPU is not a limiting factor, as this frame rate is high enough to indicate that the GPU is still the primary bottleneck. If the CPU were struggling, we would expect to see a cap at lower frame rates regardless of resolution. The data shows that as resolution increases, the FPS drops, which is a classic sign of GPU limitation. The CPU's 10 threads are likely sufficient for Thief's workload, and its boost clock of 4.90 GHz provides the single-thread speed needed for smooth gameplay. Overall, the CPU is a capable partner that does not detract from the GPU's performance.
