Thief

The Intel Core Ultra 5 225 and AMD Radeon RX 6750 XT combination delivers a highly capable 1080p and 1440p experience in Thief, with the data showing a clear shift in system bottleneck behavior as resolution increases. The measured frame rates indicate that while the CPU provides ample headroom for high-refresh gaming at lower resolutions, the GPU becomes the definitive limiting factor at 4K, where even the lowest settings struggle to maintain 60 FPS consistently.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 5 225 is a 10-core, 10-thread desktop processor built on the Arrow Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.90 GHz. It features a 20 MB shared L3 cache, with 192 KB of L1 and 3 MB of L2 per core. This configuration places it in the 85th percentile among all CPUs, with a benchmark data set showing strong single-thread and multi-thread performance. In Cinebench R23, the chip scores 3655 points in single-core and 25891 points in multi-core, indicating that it has the raw processing power to feed a discrete GPU in a 2014 stealth title like Thief without becoming a constraint.

The nearestRivals data positions this CPU in a tightly contested cluster. The AMD Ryzen 5 5600F posts an average benchmark score of 36945, which is a 0% delta from the Core Ultra 5 225's average of 36938. The Ryzen 5 5500X3D is just 0.2% behind, and the AMD Ryzen AI 7 PRO 450 trails by 0.4%. This means the Core Ultra 5 225 is statistically equivalent to its direct competitors in general compute workloads, but its architecture provides robust single-threaded performance that is relevant for Thief's engine.

In the context of Thief's measured results, the CPU's role is most apparent at 1080p. At 1920x1080 with Low settings, the combo hits 196 FPS, which is a very high frame rate that suggests the CPU is capable of pushing the game engine to its limits without bottlenecking the GPU. The fact that the Ultra 5 225 has a boost clock of 4.90 GHz and 10 physical cores means it can handle both the game's main thread and background tasks, ensuring that frame pacing remains stable even when the GPU is producing over 150 FPS. The data shows that at 1080p Medium, the average FPS is 148, which is still exceptionally high, further confirming that the CPU is not the primary limiter at this resolution.

However, the CPU's influence wanes as resolution increases. At 4K, the average FPS drops to 46 on High settings and 43 on Ultra, which is a massive reduction from the 1080p figures. This dramatic scaling indicates that the GPU is saturated at higher resolutions, and the CPU's fast cores are left waiting for the render pipeline to complete. The Core Ultra 5 225's 3 nm process node and 17,800 million transistors allow it to maintain high clock speeds under load, but the benchmark results make it clear that no amount of CPU headroom can compensate for the GPU's workload at 3840x2160.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6750 XT is a RDNA 2.0 architecture GPU with 12 GB of GDDR6 memory on a 192-bit bus, delivering a bandwidth of 432.0 GB/s. The card's base clock is 2150 MHz, with a boost clock of 2600 MHz and a game clock of 2495 MHz. The 40 ray accelerators and 2560 shading units provide the computational foundation for rasterization, and the 64 ROPs handle pixel output at a rate of 166.4 GPixel/s. This GPU sits in the 71st percentile among all GPUs, with a Passmark G3D score of 20700.

The nearestRivals list shows that the RX 6750 XT holds a slight edge over its closest competitors. The AMD Radeon R9 M395X has an average score of 25891, which is 0.5% lower than the RX 6750 XT's 26011. The FirePro W7100 and D700 trail by 0.6% and 0.7% respectively, while the NVIDIA GeForce RTX 3080 Ti Mobile is 1.1% behind. This indicates that the RX 6750 XT is a mid-to-high tier GPU that performs consistently across synthetic benchmarks, but the Thief data reveals how its real-world performance scales with resolution.

The GPU's 12 GB of VRAM is a significant asset for Thief, as the game's textures and geometry can consume substantial memory at higher resolutions. The measured FPS shows that at 2560x1440 with Medium settings, the combo achieves 102 FPS, with a minimum of 87 FPS and a maximum of 117 FPS. This suggests that the GPU has enough memory bandwidth and capacity to handle the game's assets at 1440p without stuttering or texture thrashing. The 432.0 GB/s bandwidth is crucial for maintaining smooth performance, as the game's open-ended stealth levels often require rapid loading of new areas.

The GPU's role becomes dominant at 3840x2160, where the 12 GB VRAM and 64 ROPs are pushed to their limits. At 4K High, the average FPS is 46, and at 4K Ultra, it drops to 43. The fact that the GPU cannot maintain 60 FPS at 4K even on Low settings (79 FPS average) indicates that the RX 6750 XT is the primary bottleneck at this resolution. The 13.31 TFLOPS FP32 compute performance is simply not sufficient to drive a 2014 game at 4K with high fidelity, and the data reflects this limitation clearly. The GPU's 2600 MHz boost clock helps at lower resolutions, but the sheer pixel count at 4K overwhelms the shading units and ROPs.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear and predictable scaling pattern across resolutions, which reveals the shifting balance between CPU and GPU load. At 1920x1080 with High settings, the combo produces 113 FPS. Moving to 2560x1440 on the same settings, the FPS drops to 78, a 31% reduction. At 3840x2160, the FPS falls further to 46, which is a 59% drop from the 1080p figure. This steep decline is characteristic of a GPU-bound scenario, where the rendering load increases exponentially with pixel count.

The scaling is even more pronounced on Low settings. At 1080p Low, the system delivers 196 FPS, which is a very high frame rate that suggests the CPU is the primary driver at this point. At 1440p Low, the FPS drops to 134, a 32% reduction, and at 4K Low, it falls to 79, a 60% drop from 1080p. The fact that the FPS at 4K Low (79) is still higher than the FPS at 4K High (46) indicates that the GPU's workload is heavily influenced by settings, but the resolution itself is the dominant factor in the performance degradation.

This scaling behavior points to the GPU as the limiting component at higher resolutions. The CPU's performance remains constant regardless of resolution, but the GPU's pixel throughput and texture fill rate are taxed more heavily as resolution increases. The RX 6750 XT's texture rate of 416.0 GTexel/s and pixel rate of 166.4 GPixel/s are sufficient for 1080p and 1440p, but at 4K, these rates are insufficient to maintain high frame rates. The data shows that the transition from 1440p to 4K results in a 41% FPS drop on High settings (from 78 to 46), which is a larger relative decrease than the 31% drop from 1080p to 1440p. This suggests that the GPU is hitting a performance wall at 4K, where the rendering pipeline becomes the bottleneck.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive picture of the system's performance across three resolutions and four settings presets. At 1920x1080, the combo delivers its best results. On Low settings, the average FPS is 196, which is the highest figure recorded in the dataset. Medium settings produce an average of 148 FPS, with a minimum of 126 and a maximum of 171, indicating a smooth experience with minimal frame drops. High settings yield 113 FPS, and Ultra settings produce 108 FPS. The small gap between High and Ultra (113 vs 108 FPS) suggests that the GPU has enough headroom at 1080p to handle the additional graphical effects of Ultra without a significant performance penalty.

At 2560x1440, the performance remains strong but shows a more pronounced impact from settings. Low settings produce 134 FPS, which is still very high and suitable for fast-paced stealth gameplay. Medium settings drop to 102 FPS, with a minimum of 87 and a maximum of 117, providing a stable experience that stays above 60 FPS at all times. High settings yield 78 FPS, and Ultra settings drop to 74 FPS. The 1440p data shows that the system can maintain over 60 FPS on all settings, making this resolution the sweet spot for a balance between visual quality and performance.

At 3840x2160, the performance degrades significantly, and the system struggles to maintain playable frame rates on higher settings. Low settings produce 79 FPS, which is the only 4K preset that exceeds 60 FPS. Medium settings drop to 60 FPS, with a minimum of 51 and a maximum of 69, which means the system will occasionally dip below 60 FPS during demanding scenes. High settings produce 46 FPS, and Ultra settings drop to 43 FPS. The 4K data indicates that the GPU is the limiting factor, as even the lowest settings cannot consistently maintain 60 FPS, and the higher presets result in sub-50 FPS performance that may be unsuitable for smooth gameplay.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this Intel Core Ultra 5 225 and AMD Radeon RX 6750 XT combination depend heavily on the target resolution and desired frame rate. For players using a 1920x1080 display, the Ultra preset is the clear recommendation, as it delivers 108 FPS average, which is more than sufficient for the game's stealth mechanics. The difference between High (113 FPS) and Ultra (108 FPS) is only 5 FPS, so the visual enhancements of Ultra come at a minimal performance cost. This makes Ultra the best choice for 1080p, as it provides the highest visual fidelity without sacrificing smoothness.

At 2560x1440, the Medium preset offers the best balance of performance and visual quality. The Medium settings produce 102 FPS average, with a minimum of 87 FPS, ensuring that the game never drops below 60 FPS. The High preset at 1440p yields 78 FPS, which is still playable, but the 24 FPS increase from High to Medium is significant enough to recommend Medium for a smoother experience. The Ultra preset at 1440p produces 74 FPS, which is close to High, but the Medium preset provides a more substantial performance buffer for demanding scenes.

For 3840x2160, the recommendation is more nuanced. The Low preset delivers 79 FPS, which is the only 4K setting that exceeds 60 FPS, but it compromises visual quality. The Medium preset produces 60 FPS average, with a minimum of 51 FPS, which means the game will occasionally dip below 60 FPS but remains largely playable. Given that the Medium preset at 4K offers a significant visual improvement over Low while maintaining a playable average frame rate, it is the recommended choice for 4K. The High and Ultra presets at 4K are not recommended, as their average frame rates of 46 and 43 FPS respectively are likely to cause noticeable stuttering in a game that requires precise movement and timing. The data indicates that the Medium preset at 4K is the highest setting that can be used without sacrificing playability.
