Thief

The Intel Core Ultra 5 225 pairs with the AMD Radeon RX 570 in Thief, a combination that produces a narrow operating window between playability and slideshow. Benchmark results place this pairing at rank 2744 out of 2851 tested combos, meaning it outperforms only a small fraction of the database’s configurations. The data shows a system constrained primarily by the graphics card, where even the strongest CPU headroom cannot compensate for the GPU’s memory and compute limitations at higher resolutions.

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 processor from the Core Ultra Series 2, built on Arrow Lake-S architecture using a 3 nm process from TSMC. Its base clock runs at 3.30 GHz with a boost clock of 4.90 GHz, and it carries 20 MB of shared L3 cache alongside 3 MB of L2 per core. This processor sits in the 85th percentile of all CPUs in the database, with an average benchmark score of 36938, putting it statistically level with the AMD Ryzen 5 5600F (deltaPct 0) and slightly ahead of the AMD Ryzen 5 5500X3D (deltaPct -0.2) and the AMD Ryzen AI 7 PRO 450 (deltaPct -0.4).

For Thief, a 2014 stealth title, the CPU’s single-thread performance matters more than its multi-core muscle. In Cinebench R23, the Ultra 5 225 scores 3655 in single-core and 25891 in multi-core, indicating that per-thread capability is strong enough to feed even a modest GPU without bottlenecking at lower resolutions. The 10 threads are more than sufficient for a game of Thief’s era, which typically leverages only a few cores for gameplay logic and physics. The PassMark single-thread score of 4412 further confirms that the CPU can handle frame pacing at high refresh rates, though the measured FPS data shows this is rarely relevant here since the GPU caps output.

The processor’s 65 W TDP and dual-channel DDR5 memory support with 102.4 GB/s bandwidth provide ample memory throughput for the game’s data streaming needs. However, the benchmark results indicate that the CPU is never the limiting factor in this pairing. At 1080p Low, the system reaches 75 FPS average, but at 1080p Ultra it drops to 41 FPS, a pattern that points to GPU saturation rather than CPU stalls. The CPU’s 85th percentile ranking versus the GPU’s 74th percentile suggests a slight imbalance favoring the processor, but Thief’s engine is not demanding enough to expose CPU weaknesses even at the highest settings.

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

The AMD Radeon RX 570 is a Polaris 20 chip built on GCN 4.0 architecture with a 14 nm process from GlobalFoundries. It operates at a base clock of 1168 MHz and a boost clock of 1244 MHz, with 4 GB of GDDR5 memory on a 256-bit bus delivering 224.0 GB/s bandwidth. The GPU has 2048 shading units, 128 texture mapping units, and 32 ROPs, which translates to a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. Its FP32 throughput is 5.095 TFLOPS, and it supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

This GPU ranks in the 74th percentile of all GPUs in the database, with an average benchmark score of 28766. Its nearest rivals include the AMD Radeon RX 6800M (deltaPct -0.4), the AMD Radeon R9 M295X (deltaPct 0.7), the AMD Radeon RX 470 (deltaPct -0.8), and the NVIDIA Quadro RTX 8000 (deltaPct 1.2). The RX 570 is an end-of-life product released in April 2017, and its 4 GB VRAM is a critical limitation for Thief at higher resolutions.

In Thief, the GPU’s role is dominant across all measured scenarios. At 1080p Low, the RX 570 delivers 75 FPS average, which is the highest result in the entire dataset. But stepping to Medium drops the average to 57 FPS, High to 43 FPS, and Ultra to 41 FPS. The VRAM buffer becomes a bottleneck at 1440p and 4K, where the 4 GB capacity is insufficient for the game’s texture streaming at High and Ultra presets. The memory bandwidth of 224.0 GB/s helps at lower settings but cannot overcome the capacity shortfall. The data shows that the GPU’s compute power is adequate for 1080p gameplay, but its memory subsystem limits higher-resolution performance.

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

The measured FPS data reveals a steep resolution penalty that confirms the GPU as the primary bottleneck. At 1080p Low, the system averages 75 FPS. Moving to 1440p Low, the average falls to 51 FPS, a 32% drop. At 4K Low, the average plummets to 30 FPS, which is a 60% reduction from the 1080p baseline. This scaling pattern is typical of a GPU that cannot sustain fill-rate demands as pixel count increases.

For Medium settings, the drop is similarly stark: 57 FPS at 1080p, 39 FPS at 1440p (a 32% decrease), and 23 FPS at 4K (a 60% decrease from 1080p). High settings follow the same trajectory: 43 FPS at 1080p, 30 FPS at 1440p, and 17 FPS at 4K. Ultra settings are nearly identical to High at each resolution: 41 FPS at 1080p, 28 FPS at 1440p, and 17 FPS at 4K.

The fact that High and Ultra produce nearly identical results at each resolution (17 FPS at 4K for both) suggests that the game’s Ultra preset does not add significant GPU load beyond High, or that the RX 570 is already saturated at High. The narrowing gap between High and Ultra at higher resolutions indicates that the GPU is hitting a hard performance ceiling. The CPU’s performance headroom is irrelevant here, as the FPS drops scale almost linearly with pixel count, which is a classic sign of GPU-bound rendering. The 4K results (17-30 FPS) are unplayable, while 1440p offers marginal playability only at Low (51 FPS), and 1080p is the only resolution where the system consistently exceeds 40 FPS across all settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of Intel Core Ultra 5 225 and AMD Radeon RX 570 ranks 2744 out of 2851 tested combos in Thief. This places the pairing in the bottom 4% of all configurations in the database. The rank reflects the GPU’s age and memory limitations, not the CPU’s capabilities. The Ultra 5 225 is a modern processor with an 85th percentile CPU ranking, but its pairing with a 74th percentile GPU from 2017 drags the combined score down significantly.

In this game, the combo’s rank is driven almost entirely by the GPU. The data shows that the CPU’s nearest rivals (AMD Ryzen 5 5600F, AMD Ryzen 5 5500X3D, AMD Ryzen AI 7 PRO 450, Intel Core i9-12900T) all have average scores within 0.5% of the Ultra 5 225, meaning any of these CPUs would produce nearly identical results with the RX 570. Conversely, the GPU’s rivals (RX 6800M, R9 M295X, RX 470, RTX 8000) span a wider performance range, and swapping in a stronger GPU would shift the combo rank substantially. The measured FPS data underscores this: the system’s performance at 1080p Low (75 FPS) is acceptable, but the 4K results (17-30 FPS) place it at the bottom of the database’s tested configurations. The rank of 2744 out of 2851 is a direct consequence of the GPU’s 4 GB VRAM and Polaris compute limits, which cannot handle Thief’s higher-resolution demands.

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

At 1920x1080, the system delivers its best results. Low settings produce an average of 75 FPS, which is the highest score in the entire dataset. Medium settings average 57 FPS with a minimum of 48 FPS and a maximum of 65 FPS. High settings average 43 FPS, and Ultra settings average 41 FPS. The jump from Low to Medium is a 24% drop, while the drop from Medium to High is another 25%, but High to Ultra only costs 5% performance.

At 2560x1440, the averages fall across the board. Low settings average 51 FPS, Medium averages 39 FPS with a minimum of 33 FPS and a maximum of 45 FPS, High averages 30 FPS, and Ultra averages 28 FPS. The gap between Low and Medium is 24%, Medium to High is 23%, and High to Ultra is 7%. The 1440p results show that only Low settings remain consistently above 50 FPS, while Medium stays above 30 FPS but below 40 FPS.

At 3840x2160, the system struggles to maintain playability. Low settings average 30 FPS, which is exactly at the threshold of playability for some users. Medium averages 23 FPS with a minimum of 19 FPS and a maximum of 26 FPS. High averages 17 FPS, and Ultra also averages 17 FPS. The 4K results are uniformly poor, with the minimum FPS at Medium (19 FPS) dipping below 20 FPS, indicating severe frame drops during demanding scenes.

Settings Recommendations — which preset gives the best experience per the measured rows

The data indicates that 1080p is the only viable resolution for this combination, and within that resolution, Low settings offer the most comfortable experience. At 1080p Low, the system averages 75 FPS, which provides smooth gameplay without any frame rate concerns. Medium settings at 1080p still deliver 57 FPS, which is acceptable for most players, and the minimum of 48 FPS suggests occasional dips but no sustained stuttering.

For players prioritizing visual quality, 1080p High at 43 FPS is playable but sits close to the edge of smoothness, while 1080p Ultra at 41 FPS offers marginal improvement over High at a 5% cost. The data does not justify using Ultra over High at 1080p, as the visual difference is likely minimal while the frame rate penalty is measurable.

At 1440p, only Low settings (51 FPS) provide a consistently playable experience. Medium at 39 FPS is borderline, and High (30 FPS) and Ultra (28 FPS) are too sluggish for fast-paced stealth gameplay. At 4K, all settings fall below 30 FPS, making the resolution unplayable regardless of preset. The best experience per the measured rows is 1080p Low for maximum fluidity, or 1080p Medium as a compromise between visual fidelity and frame rate. Users should avoid 1440p High/Ultra and all 4K settings, as the measured averages fall below 30 FPS, which is insufficient for Thief’s traversal and combat mechanics.
