Thief

Thief, the 2014 stealth classic, remains a demanding title for modern hardware, particularly at high resolutions. This analysis examines the Intel Core Ultra 7 155H paired with the AMD Radeon RX 7900M, a mobile combination that delivers a strong but resolution-dependent experience. The data shows this setup ranks in the 62nd percentile of all tested combinations, with performance scaling that clearly identifies the GPU as the primary bottleneck in this specific pairing.

How This Combo Ranks

The Intel Core Ultra 7 155H and AMD Radeon RX 7900M combination sits at rank 1076 out of 2851 tested combos in Thief. This places it in the top 38% of all systems tested, a solid position for a mobile platform. The ranking reflects a balanced pairing where neither component is severely mismatched for the game's engine, though the GPU becomes the limiting factor as resolution increases.

To contextualize this rank, the CPU itself holds the 83rd percentile among all processors tested. The GPU is even stronger, holding the 94th percentile among all graphics cards. The gap between the CPU's percentile and the overall combo rank indicates that Thief is not heavily CPU-bound at typical gaming resolutions. If the CPU were the limiting factor, we would expect the combo rank to be closer to the CPU's 83rd percentile. Instead, the 62nd percentile suggests the GPU's performance ceiling is being reached before the CPU's potential is exhausted.

Comparing the combo's measured frame rates to the CPU's synthetic benchmark scores reinforces this interpretation. The Core Ultra 7 155H achieves a Cinebench R23 multi-core score of 15028 and a single-core score of 1743. These are respectable numbers for a mobile chip, but in Thief, the frame rates at 1080p Ultra (115 FPS) and 4K Ultra (46 FPS) show a dramatic drop that aligns with GPU load, not CPU capability.

The combo's rank of 1076 out of 2851 means it outperforms 1775 other tested configurations. This is not a top-tier enthusiast desktop setup, but for a mobile platform with a 28W TDP CPU and a 180W TDP GPU, the position is competitive. The data indicates that users of this combo will experience smooth gameplay at 1080p, good performance at 1440p, and playable but compromised frame rates at 4K, particularly at higher settings presets.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, built on Intel's 7nm process. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The chip features a 24 MB shared L3 cache and supports DDR5 memory with a dual-channel bus providing 89.6 GB/s of bandwidth. Its TDP is 28W, which is typical for a high-end mobile processor.

In Thief, the CPU's role is to feed the GPU with draw calls and handle game logic. The game was released in 2014, and its engine is not particularly demanding on modern multi-core processors. The Core Ultra 7 155H's 16 cores and 22 threads are far more than Thief requires. The single-thread performance, as measured by a Cinebench R23 single-core score of 1743, is sufficient for the game's primary thread.

The data from the measured FPS supports the conclusion that the CPU is not the bottleneck. At 1080p with Low settings, the combo achieves 168 FPS. Moving to 1080p Ultra drops this to 115 FPS, a 31% reduction. This difference is more attributable to the GPU's workload increasing with better graphics settings rather than CPU limitations. Similarly, at 4K Low, the combo manages 84 FPS, while at 4K Ultra it drops to 46 FPS. The consistent pattern across resolutions is that higher settings presets cost more FPS, which is a GPU-bound behavior.

The CPU's Passmark multithread score of 24873 and its average benchmark score of 32697 place it in the 83rd percentile. Its nearest rivals include the Intel Core i5-14600T with an average score of 32707 (0% delta) and the AMD Ryzen AI 7 PRO 360 with 32662 (0.1% delta). These comparisons show that the Core Ultra 7 155H is squarely in the middle of its performance class. In Thief, the game's engine does not heavily leverage the CPU's multi-threading capabilities, so the frame rates are more dependent on the GPU's ability to render frames.

The CPU's 89.6 GB/s memory bandwidth is adequate for Thief's data streaming needs. The game's levels are not exceptionally large, and the dual-channel DDR5 configuration provides sufficient throughput. The 24 MB L3 cache also helps reduce memory latency for frequently accessed data. Overall, the CPU provides a stable foundation for the GPU to operate at its full potential, and the benchmark data shows no signs of CPU-induced frame rate dips.

GPU Role

The AMD Radeon RX 7900M is the dominant component in this pairing. It is based on the Navi 31 chip with RDNA 3.0 architecture, built on TSMC's 5nm process. The GPU has 16 GB of GDDR6 memory on a 256-bit bus, providing 576.0 GB/s of bandwidth. It features 4608 shading units, 288 texture mapping units, and 192 raster output units. The base clock is 1825 MHz with a boost clock of 2090 MHz. The GPU's TDP is 180W, which is high for a mobile part.

The RX 7900M holds the 94th percentile among all GPUs tested, with an average benchmark score of 97487. Its nearest rivals include the AMD Radeon Pro VII (score 97131, 0.4% delta) and the NVIDIA Quadro RTX 6000 (score 101872, -4.3% delta). This places the RX 7900M in the upper echelon of graphics cards, and its performance in Thief reflects this.

In Thief, the GPU's performance is the determining factor for frame rates at all resolutions. At 1080p Low, the combo achieves 168 FPS. This is a high frame rate, but it is not limited by the CPU. The GPU has ample headroom at this resolution and settings level. At 1080p Ultra, the frame rate drops to 115 FPS, a 31.5% decrease. This drop is due to the increased shading, texture, and geometry work required by the Ultra preset.

The RX 7900M's 16 GB of VRAM is a significant advantage in Thief. The game can use more than 8 GB of VRAM at 4K with high-quality textures, and the 16 GB capacity ensures that the GPU does not need to swap textures to system memory, which would cause stuttering. The 576.0 GB/s memory bandwidth is also crucial for handling the large texture sets and high-resolution rendering.

The GPU's pixel rate of 401.3 GPixel/s and texture rate of 601.9 GTexel/s indicate strong raw fill rate capabilities. The FP32 performance of 38.52 TFLOPS is substantial for a mobile GPU. These specifications translate into the measured frame rates: at 1440p High, the combo achieves 83 FPS, and at 4K High, it achieves 49 FPS. The scaling from 1440p to 4K at High settings shows a 41% reduction in FPS, which is consistent with the 2.25x increase in pixel count.

The GPU's RT cores (72) and support for DirectX 12 Ultimate are not heavily utilized in Thief, which was released before ray tracing became mainstream. The game uses DirectX 11 features, so the RX 7900M's modern architecture is not fully leveraged. However, the raw rasterization performance is more than sufficient to handle Thief's visual effects, including dynamic lighting and shadows.

Resolution Scaling

The measured FPS data shows a clear pattern of performance degradation as resolution increases. At 1080p Low, the combo achieves 168 FPS. At 1440p Low, this drops to 143 FPS, a 14.9% reduction. At 4K Low, the frame rate is 84 FPS, a 50% reduction from 1080p. This scaling is consistent with the pixel count increase: 1440p has 1.78x the pixels of 1080p, and 4K has 4x the pixels of 1080p.

The scaling for the Ultra preset follows a similar trajectory. At 1080p Ultra, the combo achieves 115 FPS. At 1440p Ultra, it drops to 79 FPS, a 31.3% reduction. At 4K Ultra, the frame rate falls to 46 FPS, a 60% reduction from 1080p. The larger percentage drop at Ultra settings compared to Low settings indicates that the GPU is working harder at higher settings, making the resolution increase more punishing.

The data reveals that the GPU is the limiting component at all resolutions above 1080p. If the CPU were the bottleneck, we would expect the frame rates to remain relatively constant across resolutions, or at least to scale in a sub-linear fashion. Instead, the frame rates drop proportionally with pixel count, which is characteristic of a GPU-bound scenario.

At 4K, the combo achieves playable frame rates only at Low settings (84 FPS) and Medium settings (64 FPS). The High preset at 4K yields 49 FPS, which is borderline playable, while the Ultra preset at 46 FPS is below the 60 FPS threshold that most gamers prefer. This indicates that 4K gaming on this combo requires compromising on visual quality to maintain smooth gameplay.

The 1440p resolution provides the best balance for this combo. At 1440p High, the combo achieves 83 FPS, which is smooth. At 1440p Ultra, it achieves 79 FPS, still well above the 60 FPS target. This suggests that 1440p is the sweet spot for this hardware, allowing for high visual settings without sacrificing frame rate.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. The data provides clear guidance for each resolution.

At 1920x1080, all settings presets are playable. The Low preset achieves 168 FPS, which is excellent for high-refresh-rate monitors. The Medium preset achieves 152 FPS with a minimum of 129 FPS, indicating stable performance. The High preset achieves 121 FPS, and the Ultra preset achieves 115 FPS. For 1080p gaming, the Ultra preset is recommended because it provides the highest visual quality while still maintaining an average frame rate above 110 FPS. The 4 FPS difference between High and Ultra at 1080p is minimal, so choosing Ultra is the best option.

At 2560x1440, the choice becomes more nuanced. The Low preset achieves 143 FPS, which is very high. The Medium preset achieves 109 FPS with a minimum of 92 FPS. The High preset achieves 83 FPS, and the Ultra preset achieves 79 FPS. For 1440p, the High preset is recommended as the best balance. It provides significantly better visuals than Medium while maintaining an average frame rate of 83 FPS, which is above the 60 FPS threshold. The Ultra preset at 79 FPS is also viable, but the 4 FPS gain from High to Ultra is marginal, and the High preset may have more headroom for demanding scenes.

At 3840x2160, the settings need to be chosen carefully. The Low preset achieves 84 FPS, which is playable. The Medium preset achieves 64 FPS with a minimum of 54 FPS, which is borderline. The High preset achieves 49 FPS, and the Ultra preset achieves 46 FPS, both of which are below the 60 FPS target. For 4K gaming, the Medium preset is the highest setting that maintains an average frame rate above 60 FPS. The minimum FPS of 54 for Medium indicates that there may be occasional dips below 60 FPS, but the average is acceptable. The Low preset is the safest choice for consistent 60+ FPS performance at 4K, but the Medium preset offers a better balance of visual quality and frame rate for most users.

The data shows that the combo's performance scales predictably with settings. For users who prioritize frame rate over visual fidelity, the Low preset at 1440p or 1080p provides the highest frame rates. For users who want the best visual experience, the Ultra preset at 1080p or the High preset at 1440p are the recommended choices. At 4K, users should stick to Medium or Low settings to maintain playable frame rates.
