Thief

The Intel Core Ultra 5 225 and Intel Arc B580 combination delivers a playable experience in Thief, but the data clearly indicates that the graphics card is the primary bottleneck at higher resolutions. The combo ranks in the 25th percentile of all tested configurations, with performance scaling that is heavily dependent on both resolution and quality settings. While the CPU provides ample headroom, the GPU's limits become apparent as the pixel count increases, making this a pairing best suited for 1080p and lighter 1440p workloads.

Resolution Scaling

The measured frame rates reveal a steep performance drop as resolution increases, a classic sign of GPU-bound rendering. At 1080p with High settings, the combo produces 87 FPS. Moving to 1440p drops this to 60 FPS, a 31% reduction. The jump to 4K is even more punishing, with the average falling to 35 FPS, a 60% reduction from the 1080p figure. This scaling pattern is consistent across all settings presets, indicating that the Intel Arc B580's rendering throughput is the limiting factor.

The data shows that the gap between Low and Ultra settings narrows as resolution rises. At 1080p, the difference between Low (150 FPS) and Ultra (83 FPS) is 67 FPS, a substantial margin. At 1440p, the spread shrinks to 46 FPS (103 FPS Low vs. 57 FPS Ultra). At 4K, the difference compresses further to 28 FPS (61 FPS Low vs. 33 FPS Ultra). This compression suggests that at 4K, the GPU is so saturated that even reducing the workload through lower settings cannot fully compensate for the raw pixel count, though it does push the average from 33 FPS to a more playable 61 FPS.

The performance drop from 1440p to 4K is particularly steep. At Medium settings, 1440p yields 78 FPS, while 4K falls to 46 FPS, a 41% decline. This implies that the memory bandwidth and pixel fill rate of the Arc B580 are insufficient for sustained 4K performance, even on a 2014 title. The 456.0 GB/s bandwidth and 213.6 GPixel/s pixel rate are adequate for 1440p but become strained at 4K, where the GPU must process four times the pixels of 1080p.

Conversely, the scaling from 1080p to 1440p is less severe but still notable. At Ultra settings, the drop is from 83 FPS to 57 FPS, a 31% reduction. This suggests that the GPU can handle moderate resolution increases but begins to lose its margin as settings are raised. The CPU, with its 10 cores and 10 threads, does not appear to be a limiting factor in these scenarios, as the frame rate scales consistently with resolution rather than showing signs of CPU-related stalls.

How This Combo Ranks

In the database of tested hardware combinations for Thief, this pairing of the Intel Core Ultra 5 225 and Intel Arc B580 achieves a rank of 2138 out of 2851 total combos. This places it in the lower 25% of all tested systems, indicating that while it is functional, it is far from a top-tier configuration for this game. The rank reflects the combination's overall performance, which is dragged down by the GPU's limitations at higher resolutions.

The CPU itself is a strong performer in synthetic benchmarks, with an average benchmark score of 36938 and a percentile rank of 85 among all CPUs. Its nearest rivals include the AMD Ryzen 5 5600F (0% delta), AMD Ryzen 5 5500X3D (-0.2% delta), AMD Ryzen AI 7 PRO 450 (-0.4% delta), and Intel Core i9-12900T (-0.5% delta). This places the Ultra 5 225 in the upper echelon of processors, suggesting it is not the weak link in this pairing.

The GPU, however, is a different story. The Intel Arc B580 has an average benchmark score of 23021 and a percentile rank of 68 among all GPUs. Its nearest rivals include the AMD Radeon RX 580 2048SP (-0.2% delta), NVIDIA GeForce RTX 2080 (0.6% delta), NVIDIA GeForce RTX 3080 (-0.7% delta), and NVIDIA P106-100 (-1% delta). Interestingly, the B580's average score sits between the RTX 2080 and RTX 3080, but its in-game performance in Thief is clearly below what those older high-end cards would deliver, highlighting that synthetic scores do not always translate directly to game performance.

The combo rank of 2138 suggests that many other CPU-GPU pairings deliver better results in Thief. This is likely due to the B580's driver overhead or architectural quirks in this specific title, as the GPU's raw compute capabilities (13.67 TFLOPS FP32) are respectable. The data indicates that users seeking higher ranks would need a more powerful GPU, as the CPU is already performing near the top of its class.

GPU Role

The Intel Arc B580 is the primary determinant of frame rates in this configuration, particularly at higher resolutions. Its 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is sufficient for 1080p and 1440p but becomes a constraint at 4K. The memory operates at 2375 MHz (19 Gbps effective), and the GPU has a base and boost clock of 2670 MHz. These clocks are identical, suggesting a fixed operating point rather than dynamic boosting.

The GPU's architecture, Xe2-HPG on a 5 nm process, includes 2560 shading units, 160 TMUs, and 80 ROPs. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are moderate figures that explain the performance drop at 4K. The B580's 20 ray tracing cores are present but not directly relevant to Thief, which does not heavily utilize RT features.

The measured FPS data shows that the GPU is the bottleneck in most scenarios. At 4K Ultra, the combo manages only 33 FPS, which is below the threshold for smooth gameplay. Even at 4K Low, the 61 FPS average is only marginally playable, indicating that the GPU is struggling to maintain consistent frame delivery. The 1440p results are more favorable, with High settings achieving 60 FPS and Medium hitting 78 FPS, suggesting that this resolution is the practical ceiling for this GPU in Thief.

The GPU's performance relative to its rivals is telling. While its average benchmark score is within 1% of the RTX 2080 and RTX 3080, the actual in-game results in Thief are likely lower due to driver maturity. The B580's PassMark G3D score of 15748 is respectable, but its DirectX 11 score of 128 and DirectX 12 score of 76 suggest that API-specific optimizations may be lacking. This could explain why the combo ranks lower than expected in Thief, which has specific rendering requirements.

Measured FPS Breakdown

At 1920x1080, the combo delivers strong performance across all settings. Low settings produce an average of 150 FPS, which is far above the refresh rate of most monitors. Medium settings yield 114 FPS with a minimum of 97 FPS and maximum of 131 FPS, indicating stable frame delivery. High settings drop to 87 FPS, while Ultra settings bring the average down to 83 FPS. These numbers suggest that 1080p is the sweet spot for this pairing, with even Ultra settings maintaining a playable frame rate.

Moving to 2560x1440, the performance drops noticeably. Low settings still manage 103 FPS, which is excellent, but Medium falls to 78 FPS (min 66, max 90), and High drops to 60 FPS. Ultra settings dip to 57 FPS, which is on the lower edge of playability for fast-paced action. The data shows that 1440p is viable for this combo, but users will need to compromise on settings to maintain smooth gameplay.

At 3840x2160, the GPU's limitations become starkly apparent. Low settings achieve 61 FPS, which is playable, but Medium falls to 46 FPS (min 39, max 53), and High drops to 35 FPS. Ultra settings produce only 33 FPS, making the game nearly unplayable at this resolution. The frame time variance at 4K Medium (39-53 FPS) indicates inconsistent performance, which can be distracting during gameplay.

The data reveals a clear pattern: the combo is capable of high frame rates at 1080p, adequate performance at 1440p, and marginal results at 4K. The 1080p Medium setting offers a good balance, with 114 FPS average and a tight frame time range. For users prioritizing visual quality, 1440p High at 60 FPS is the maximum playable setting, while 4K should be avoided unless the user is willing to accept sub-40 FPS averages.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is at 1080p with Medium settings. This configuration delivers an average of 114 FPS with a minimum of 97 FPS and maximum of 131 FPS, providing a smooth and responsive experience. The frame time consistency at this setting is excellent, with only a 34 FPS spread between minimum and maximum, suggesting minimal stuttering.

For users with 1440p monitors, High settings at 60 FPS is the recommended choice. This provides a solid balance between visual fidelity and performance, though the average is exactly at the 60 FPS mark, which could result in occasional dips below that threshold. Medium settings at 78 FPS offer more headroom and are a safer choice for competitive play or if the user is sensitive to frame drops.

At 4K, the data suggests that only Low settings are viable, with an average of 61 FPS. However, this comes with significant visual compromises. Medium settings at 46 FPS are borderline playable but may feel sluggish, while High and Ultra settings are not recommended due to sub-40 FPS averages. Users with 4K displays should consider lowering the resolution to 1440p for a better experience.

The Ultra preset is generally not recommended for this combo. At 1080p, it achieves 83 FPS, which is acceptable, but the marginal visual improvement over High is not worth the 4 FPS difference. At 1440p, Ultra drops to 57 FPS, which is below the 60 FPS target, and at 4K, it falls to 33 FPS, which is unplayable. The High preset offers a better balance, with 87 FPS at 1080p and 60 FPS at 1440p.

CPU Role

The Intel Core Ultra 5 225 is a strong processor that does not bottleneck the system in Thief. With 10 cores and 10 threads, it provides ample processing power for the game's CPU-bound tasks. The base clock of 3.30 GHz and boost clock of 4.90 GHz are respectable, and the 20 MB of shared L3 cache helps with data locality. The CPU's Cinebench R23 multi-core score of 25891 and single-core score of 3655 indicate robust performance across both lightly and heavily threaded workloads.

The CPU's synthetic benchmarks suggest it is more than capable of feeding the GPU. The PassMark multi-thread score of 30459 and single-thread score of 4412 are both strong, and the data compression score of 302811 indicates efficient handling of memory-intensive tasks. The CPU's 102.4 GB/s memory bandwidth, while not exceptional, is sufficient for this game's requirements.

In the context of Thief, the CPU's role is to manage game logic, AI, and physics calculations. The frame rate scaling with resolution and settings suggests that the CPU is not the limiting factor, as performance drops consistently with GPU workload rather than showing CPU-related bottlenecks. At 1080p Low, the combo achieves 150 FPS, which is likely near the CPU's maximum frame delivery capability, but this is still well above the 60 FPS target.

The CPU's nearest rivals in the benchmark database include the AMD Ryzen 5 5600F (0% delta) and AMD Ryzen 5 5500X3D (-0.2% delta), indicating that the Ultra 5 225 is competitively positioned. Its 85th percentile ranking among all CPUs confirms that it is a high-end processor. The 3 nm process node and Arrow Lake architecture contribute to its efficiency, with a TDP of 65 W being notably low for a desktop CPU of this performance class.

The data suggests that the CPU is not the bottleneck in this pairing. The measured FPS values in Thief are consistently limited by the GPU, particularly at resolutions above 1080p. For users looking to improve performance, upgrading the GPU would yield greater benefits than upgrading the CPU. The CPU's 10 threads are sufficient for this 2014 title, which does not heavily utilize multi-core processing, and its high single-core performance ensures that legacy game engines run smoothly.
