Thief with Intel Core Ultra 7 155H + NVIDIA GeForce RTX 4080, In-Depth Analysis
# How This Combo Ranks
The Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 4080 ranks 1128th out of 3720 tested combos in Thief, placing it in the 70th percentile of all tested configurations. This is a strong result for a mobile-first CPU paired with a desktop-class GPU, though the ranking reflects the game's age and the fact that many higher-end desktop combos naturally outperform a laptop CPU in this title. The combo's position suggests it delivers a solid, above-median experience, but it is not near the top of the leaderboard—there are 2592 combos ranked above it, which indicates that while this pairing is capable, it does not dominate the charts.
The CPU itself holds an 83rd percentile ranking among all processors, which is notably higher than the combo's overall game rank. This gap hints that the GPU, while powerful, is not being fully utilized in Thief at all settings—or that the game's engine places limitations that prevent the combo from climbing higher. Conversely, the GPU sits at an 86th percentile among all GPUs, so both components individually are above-average performers. The delta between the combo rank and component percentiles suggests that Thief's workload does not scale perfectly with this hardware pairing, likely due to the game's 2014 engine not leveraging modern multi-core or high-end GPU features efficiently.
# Settings Recommendations
The measured data shows a clear pattern: Medium settings offer the best balance of performance and visual fidelity across all resolutions. At 1080p, Medium delivers 152 FPS average with a minimum of 129 FPS and a maximum of 175 FPS, which is only 16 FPS behind Low settings but 23 FPS ahead of High settings. At 1440p, Medium hits 122 FPS average (minimum 103, maximum 140), which is 26 FPS ahead of High and 34 FPS ahead of Ultra. Even at 4K, Medium maintains 71 FPS average with a minimum of 61 FPS and maximum of 82 FPS—the only 4K setting that stays above the 60 FPS threshold for smooth gameplay.
Ultra settings, while visually impressive, push the combo to the edge of playability. At 4K Ultra, the average drops to 52 FPS, which is below the 60 FPS target most players expect. At 1440p Ultra, the average is 88 FPS, which is acceptable but not ideal for high-refresh-rate displays. High settings at 4K yield 54 FPS average, nearly identical to Ultra, suggesting that the jump from High to Ultra at 4K provides minimal performance cost but also minimal benefit—the bottleneck is elsewhere. Low settings at 4K produce 94 FPS, which is the only 4K preset that approaches 100 FPS, but the visual quality loss is substantial.
The data strongly supports Medium as the recommended preset. It consistently delivers the highest minimum FPS across all resolutions (129 at 1080p, 103 at 1440p, 61 at 4K), meaning it provides the most consistent frame pacing. For players with 144Hz monitors at 1080p, Medium's 152 FPS average exceeds the refresh rate, while High's 135 FPS also clears it but with less headroom. At 1440p, Medium's 122 FPS is ideal for 120Hz displays, whereas High's 93 FPS would require a 90Hz panel or VRR. At 4K, Medium is the only preset that maintains 60+ FPS averages, making it the sole viable option for 60Hz 4K displays.
# Resolution Scaling
The FPS scaling from 1080p to 4K reveals where the bottleneck lies. At Medium settings, the combo delivers 152 FPS at 1080p, 122 FPS at 1440p, and 71 FPS at 4K. The drop from 1080p to 1440p is 30 FPS (a 19.7% reduction), while the drop from 1440p to 4K is 51 FPS (a 41.8% reduction). This accelerating decline with resolution is characteristic of a GPU-bound scenario at higher resolutions—the RTX 4080's workload increases substantially as pixel count rises, and the CPU has more than enough headroom to feed the GPU at 1080p but less so at 4K.
Low settings show a similar pattern: 168 FPS at 1080p, 148 FPS at 1440p, and 94 FPS at 4K. The 1080p-to-1440p drop is 20 FPS (11.9%), while the 1440p-to-4K drop is 54 FPS (36.5%). High settings follow: 135 FPS at 1080p, 93 FPS at 1440p, and 54 FPS at 4K. Here the drops are 42 FPS (31.1%) and 39 FPS (41.9%), respectively. Ultra settings show 128 FPS at 1080p, 88 FPS at 1440p, and 52 FPS at 4K, with drops of 40 FPS (31.3%) and 36 FPS (40.9%).
The pattern is consistent: the largest percentage drop always occurs between 1440p and 4K, regardless of settings. This indicates that the RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are sufficient for 4K, but the GPU's raw compute (48.74 TFLOPS FP32) becomes the limiting factor at that resolution. At 1080p, the CPU's 16 cores and 22 threads are more than adequate to maintain high frame rates, but the GPU's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s scale directly with resolution, causing the pronounced 4K penalty. The data suggests that for 1080p and 1440p gaming, this combo is CPU-limited at Low settings but becomes increasingly GPU-limited as settings rise, while at 4K it is unequivocally GPU-bound.
# Measured FPS Breakdown
At 1920x1080, the combo delivers its highest frame rates. Low settings produce 168 FPS average, Medium reaches 152 FPS (with a minimum of 129 and maximum of 175), High hits 135 FPS, and Ultra bottoms out at 128 FPS. The spread from Low to Ultra is 40 FPS, meaning that even at maximum settings, the combo loses only 23.8% of its Low-settings performance. This tight range indicates that at 1080p, the CPU is capable of driving high frame rates regardless of GPU load, and the RTX 4080 has ample headroom to handle the game's effects without significant frame rate degradation.
At 2560x1440, the performance gap widens. Low settings yield 148 FPS, Medium delivers 122 FPS (minimum 103, maximum 140), High drops to 93 FPS, and Ultra falls to 88 FPS. The spread from Low to Ultra is 60 FPS (40.5% reduction). Medium's minimum of 103 FPS is particularly notable—it stays above 100 FPS even during demanding scenes, while High and Ultra both fall below 90 FPS averages, suggesting that the GPU's workload at those settings begins to exceed its comfortable operating range.
At 3840x2160, the combo's performance becomes more constrained. Low settings manage 94 FPS, Medium achieves 71 FPS (minimum 61, maximum 82), High drops to 54 FPS, and Ultra falls to 52 FPS. The spread from Low to Ultra is 42 FPS (44.7% reduction). Medium's minimum of 61 FPS is just above the 60 FPS threshold, making it the only 4K preset that maintains playable frame rates throughout. High and Ultra both average in the low 50s, which would result in noticeable stuttering on standard 60Hz displays.
Across all resolutions, Medium settings consistently provide the highest minimum FPS relative to its average. At 1080p, the minimum is 85% of the average; at 1440p, it's 84.4%; at 4K, it's 85.9%. This consistency indicates that Medium settings produce the most stable frame pacing, which is often more important than raw average FPS for perceived smoothness. Low settings lack min/max data, but their high averages suggest they would also be stable, just with reduced visual quality.
# GPU Role
The NVIDIA GeForce RTX 4080 is a 5 nm Ada Lovelace part with 45,900 million transistors on a 379 mm² die, featuring 9,728 shading units, 304 TMUs, and 112 ROPs. Its 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is sufficient for Thief's textures at any resolution. The GPU's base clock of 2205 MHz and boost clock of 2505 MHz, combined with its 76 RT cores and 304 tensor cores, make it a formidable card for modern titles, but Thief—released in 2014—does not utilize ray tracing or DLSS, meaning much of this hardware sits idle.
The measured FPS data shows the GPU's raw compute power is the primary driver of performance scaling. At 1080p Low, the combo hits 168 FPS, which is likely near the engine's frame rate cap or the CPU's limit. As resolution increases, the GPU's pixel rate of 280.6 GPixel/s becomes the constraint. At 4K Ultra, 52 FPS corresponds to roughly 8.3 million pixels being rendered per frame, and the GPU's texture rate of 761.5 GTexel/s is being taxed by the game's high-resolution textures. The 48.74 TFLOPS FP32 performance is ample for Thief's DirectX 11 workload, but the game's older engine does not scale efficiently with such high-end hardware.
Compared to its nearest rivals, the RTX 4080 scores 54,247 in average benchmark, which is 0.1% ahead of the RTX 4080 SUPER (54,209) and 1.1% ahead of the AMD Radeon Pro W5700X (54,828). It trails the AMD Radeon RX 6750 GRE 12 GB by 2.6% (55,698) and the AMD Radeon 8060S by 2.7% (55,757). These small deltas indicate that the RTX 4080 is positioned in a tight performance band, and in Thief specifically, its 86th percentile ranking among all GPUs suggests it performs above average but not exceptionally so for this title. The GPU's memory bandwidth of 716.8 GB/s is likely sufficient for 4K, as evidenced by the 4K Medium result of 71 FPS, which suggests the bottleneck is compute rather than memory throughput.
# CPU Role
The Intel Core Ultra 7 155H is a Meteor Lake mobile processor with 16 cores and 22 threads, running at a base clock of 3.80 GHz and boost clock of 4.80 GHz. Its 24 MB of shared L3 cache and dual-channel DDR5 memory support (89.6 GB/s bandwidth) provide solid foundation for gaming, but its 28 W TDP classifies it as a power-efficient mobile chip rather than a desktop powerhouse. The CPU's 83rd percentile ranking among all processors, with an average benchmark score of 32,697, places it near the Intel Core i5-14600T (32,707, 0% delta) and AMD Ryzen AI 7 PRO 360 (32,662, 0.1% delta), while slightly behind the AMD Ryzen 5 7400F (32,750, -0.2% delta) and AMD Ryzen 7 PRO 6850H (32,812, -0.4% delta).
In Thief, the CPU's role is most evident at lower resolutions and settings. At 1080p Low, the combo achieves 168 FPS, which is likely near the CPU's limit for this game's single-threaded or lightly-threaded workload. The CPU's single-core performance, as measured by Cinebench R23 single-core score of 1,743, is adequate for Thief's AI and physics calculations, but the game's 2014 engine primarily uses a few threads, so the 16-core/22-thread configuration provides diminishing returns. The multi-core score of 15,028 in Cinebench R23 is impressive for a mobile chip, but Thief likely doesn't utilize more than 4-8 threads effectively.
The measured FPS data shows that at 1080p, the gap between Low (168 FPS) and Ultra (128 FPS) is only 40 FPS, suggesting the CPU can maintain high frame rates even when GPU load increases. However, at 4K, the gap between Low (94 FPS) and Ultra (52 FPS) is 42 FPS, indicating that the GPU becomes the dominant constraint at higher resolutions. The CPU's 22 threads and 4.80 GHz boost clock are sufficient to avoid bottlenecking the RTX 4080 at 1080p, but the data does not show the CPU holding back performance at any resolution—the consistent 40-60 FPS drops from Low to Ultra across all resolutions point to the GPU as the primary limiter.
The CPU's memory bandwidth of 89.6 GB/s is modest compared to the GPU's 716.8 GB/s, but for Thief's relatively small asset sizes, this is not a limiting factor. The L3 cache of 24 MB is ample for the game's working set, and the 7 nm process node keeps power consumption low, which is beneficial for sustained gaming sessions on mobile hardware. Overall, the Core Ultra 7 155H provides enough CPU performance to keep the RTX 4080 well-fed in Thief, but it does not boost the combo's rank beyond what the GPU alone would achieve.
