Thief

The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4080 delivers a commanding performance profile in Thief, with measured framerates that comfortably exceed playability thresholds at every tested resolution and setting combination. The dataset shows a system that scales predictably with graphical load, though the relationship between resolution, settings, and frame rate reveals distinct bottlenecks that users should consider when configuring the game.

Settings Recommendations

The measured rows indicate that the Medium preset offers the most balanced experience across all three tested resolutions, providing a substantial framerate buffer over High and Ultra settings while maintaining visual fidelity. At 1080p, Medium delivers 155 FPS average, which is 20 FPS higher than High and 27 FPS higher than Ultra, while still being only 16 FPS behind Low. The Medium preset also includes the only complete min/max data in the entire dataset, with a minimum of 131 FPS and maximum of 178 FPS at 1080p, indicating consistent frame pacing without significant dips.

At 1440p, the Medium preset again proves optimal, hitting 122 FPS average with a minimum of 103 FPS and maximum of 140 FPS. This represents a 29 FPS advantage over High and a 34 FPS advantage over Ultra at the same resolution. The 103 FPS minimum ensures that even during demanding scenes, the experience remains fluid on high-refresh-rate displays. For users prioritizing maximum quality, the High preset at 1440p still delivers a respectable 93 FPS average, but the gap to Medium is substantial enough to warrant the lower setting.

At 4K, the Medium preset produces 71 FPS average with a minimum of 61 FPS and maximum of 82 FPS. This is the only 4K configuration with complete min/max data, and the 61 FPS floor keeps gameplay above the 60 FPS threshold for standard displays. The Ultra preset at 4K drops to 52 FPS average, which falls below ideal smoothness for fast-paced stealth sequences, while High sits at 54 FPS. The Low preset at 4K reaches 94 FPS, but the visual compromise is significant. Consequently, Medium at 4K represents the sweet spot, offering playable performance without sacrificing the atmospheric lighting and shadow details that define Thief's stealth mechanics.

CPU Role

The Intel Core Ultra 5 135H features 14 cores and 18 threads, with a base clock of 3.60 GHz and boost clock of 4.60 GHz. This mobile processor, built on the Meteor Lake architecture with a 7 nm process node, demonstrates strong multi-threaded capability as evidenced by its Cinebench R23 multi-core score of 11875.5 and Passmark multi-thread score of 22422. The processor's 18 MB of shared L3 cache and dual-channel memory configuration with 89.6 GB/s bandwidth provide adequate data throughput for game logic and AI computations in Thief.

The CPU's performance percentile of 81 among all tested processors places it in the upper quintile, with its average benchmark score of 29093 sitting nearly identical to the AMD Ryzen 7 5800X at 29123, a mere 0.1% difference. This near-parity with a desktop-class competitor indicates the 135H provides ample headroom for Thief's CPU demands. The single-thread performance, reflected in the Cinebench R23 single-core score of 1700, ensures that the game's primary simulation thread receives sufficient processing power.

In the context of Thief, which is a 2014 title with relatively modest CPU requirements compared to modern games, the Core Ultra 5 135H is unlikely to be the limiting factor at any resolution. The data supports this interpretation: the framerate scaling from 1080p to 4K follows a pattern consistent with GPU-bound scenarios rather than CPU limitations. The processor's 14 cores and 18 threads provide substantial parallelism for background tasks and game engine threads, while the boost clock of 4.60 GHz handles single-threaded workloads efficiently. The measured results show that even at 1080p Low, where CPU overhead is highest relative to GPU load, the system achieves 171 FPS, suggesting the processor is not constraining performance.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this configuration, featuring 16 GB of GDDR6X memory on a 256-bit bus with 716.8 GB/s bandwidth. The GPU's Ada Lovelace architecture, built on TSMC's 5 nm process with 45,900 million transistors, delivers 48.74 TFLOPS of FP32 compute performance. Its boost clock of 2505 MHz and 9728 shading units provide substantial rasterization throughput, while 76 RT cores and 304 tensor cores offer hardware acceleration for advanced rendering features.

The GPU's benchmark scores place it in the 86th percentile among all tested graphics cards, with an average score of 54247. Its nearest rival, the RTX 4080 SUPER, scores 54209, representing only a 0.1% difference, indicating the non-SUPER variant trades blows with its successor. The RTX 4080's memory configuration of 16 GB GDDR6X proves more than sufficient for Thief at all settings, as the game's 2014-era textures and geometry do not approach the memory capacity limits.

The GPU's role becomes increasingly apparent as resolution increases. The data shows the RTX 4080 handles 1080p and 1440p with exceptional ease, maintaining framerates above 128 FPS even at Ultra settings. At 4K, the GPU begins to show its workload, with Ultra settings producing 52 FPS and High producing 54 FPS. This pattern indicates the RTX 4080 is the primary performance driver, with the CPU providing sufficient support to avoid becoming a bottleneck. The GPU's 716.8 GB/s memory bandwidth and 280.6 GPixel/s pixel rate directly influence the resolution scaling observed in the measured data.

How This Combo Ranks

This specific combination of Intel Core Ultra 5 135H and NVIDIA GeForce RTX 4080 achieves a rank of 1102 out of 3720 tested combos in Thief, placing it in the top 29.6% of all configurations. This ranking reflects the system's strong but not elite performance, as the CPU's mobile positioning and the GPU's desktop-class capabilities create an interesting balance. The rank of 1102 indicates that while the RTX 4080 provides excellent graphics throughput, the Core Ultra 5 135H's mobile architecture and power envelope prevent this combo from reaching the absolute top tier of tested systems.

The CPU's percentile of 81 and GPU's percentile of 86 suggest both components perform above average relative to their respective categories, but neither reaches the 90th percentile or beyond. This combination of high-but-not-top-tier components results in a system that ranks in the upper third of all configurations tested in Thief. The data implies that systems with more powerful desktop CPUs paired with the RTX 4080 would rank higher, while configurations with the 135H and less capable GPUs would rank lower.

The rank of 1102 out of 3720 represents a solid mid-to-upper tier placement. For Thief specifically, this ranking suggests the system delivers consistently high framerates across most settings and resolutions, with the only notable weakness appearing at 4K Ultra where the 52 FPS average falls below the 60 FPS threshold preferred by many users. The combination's ranking reflects a well-matched pairing where the RTX 4080's strengths are fully utilized without the CPU creating a significant bottleneck.

Resolution Scaling

The measured framerates reveal a clear pattern of performance degradation as resolution increases from 1080p to 4K, with the magnitude of the drop varying by settings preset. At High settings, the average FPS falls from 135 at 1080p to 93 at 1440p, a 31.1% reduction, and further to 54 at 4K, representing a 60% total drop from 1080p. This steep decline indicates the GPU is the primary limiting factor, as the pixel count quadruples from 1080p to 4K while the framerate drops by more than half.

The Low preset shows a similar pattern: 171 FPS at 1080p drops to 151 FPS at 1440p (an 11.7% reduction) and then to 94 FPS at 4K (a 45% total drop). The relatively smaller reduction from 1080p to 1440p at Low settings suggests the CPU may be providing some constraint at lower resolutions, but the substantial drop to 4K confirms GPU dominance. The Medium preset follows this trend with 155 FPS at 1080p, 122 FPS at 1440p (21.3% reduction), and 71 FPS at 4K (54.2% total drop).

Ultra settings exhibit the most severe scaling: 128 FPS at 1080p drops to 88 FPS at 1440p (31.3% reduction) and 52 FPS at 4K (59.4% total drop). The consistent pattern across all presets—where the 1080p to 1440p transition costs 11.7% to 31.3% and the 1080p to 4K transition costs 45% to 60%—strongly indicates GPU-bound performance. If the CPU were the limiting factor, the framerate would remain relatively constant across resolutions, as the CPU workload does not scale with pixel count. The data instead shows framerates declining sharply with resolution, confirming the RTX 4080 as the performance ceiling while the Core Ultra 5 135H provides adequate support.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest framerates across all settings. The Low preset produces 171 FPS average, making it the fastest configuration in the entire dataset. Medium reaches 155 FPS with a minimum of 131 FPS and maximum of 178 FPS, providing the most complete performance picture at this resolution. High settings achieve 135 FPS average, while Ultra produces 128 FPS average. The spread from Low to Ultra at 1080p is 43 FPS, indicating that even the most demanding settings maintain triple-digit framerates with ease.

At 2560x1440, performance remains strong but shows the expected reduction. Low settings deliver 151 FPS average, a 20 FPS drop from 1080p. Medium settings produce 122 FPS with a minimum of 103 FPS and maximum of 140 FPS, ensuring smooth gameplay on 144Hz displays with headroom to spare. High settings achieve 93 FPS average, while Ultra drops to 88 FPS average. The spread from Low to Ultra at 1440p is 63 FPS, showing a wider gap than at 1080p as the GPU workload increases.

At 3840x2160, the system's performance becomes more stratified. Low settings deliver 94 FPS average, still comfortably above 60 FPS. Medium settings produce 71 FPS average with a minimum of 61 FPS and maximum of 82 FPS, representing the most viable quality setting at this resolution. High settings drop to 54 FPS average, while Ultra falls to 52 FPS average. The 4K results show a 42 FPS spread from Low to Ultra, with the higher settings failing to maintain 60 FPS averages. The Medium preset's minimum of 61 FPS indicates that even in the most demanding moments, the system stays above the 60 FPS threshold, making it the recommended choice for 4K gameplay.
